1. RAy2 – Microwave LinkThe microwave link RAy2 is designed as a high-speed point-to-point wireless bridge for data transmissionunder the latest requirements of modern wireless transmission equipment.RAy2 works with an ethernet interface and can be used in backhaul networks as well as a last-mileterminal.The design of microwave link RAy2 reflects effort on meeting the strictest criteria of ETSIstandards, particularly for durability against interference, high receiver sensitivity and high output powerto achieve maximum link distance. The native gigabit Ethernet interface is able to cope with full speeduser data throughput at low latency. High availability of the link (up to 99.999%) is able to be achievedusing hitless Adaptive coding and modulation. RAy2 microwave links can also be operated as a ShortRange Device (SRD).The link properties can be summarised as:• High data throughput• Spectrum effeciency• Robustness• Security - cofiguration via http, https, ssh• User friendly interface, advanced diagnosticsKey technical features see Chapter 10, Technical parametersNoteOperation of the RAy2-xx is described in this user manual.Operation of the RAy11, RAy17 and RAy24 is described in User Manual RAy11,17,241.Operation of the RAy10 is described in the RAy10 User Manual2.1http://www.racom.eu/eng/products/m/ray17/index.html2http://www.racom.eu/eng/products/m/ray/index.html11© RACOM s.r.o. – RAy2 Microwave LinkRAy2 – Microwave Link
2. Implementation Notes2.1. Link calculationBefore a microwave link can be installed, an analysis and calculation of the microwave link must bemade first. The analysis should take place before the site survey itself to get a clear idea about the di-mensions of the antennas. The analysis consists of the following steps:• Free space loss calculation• Link budget calculation• Rain attenuation• Multipath fading• Fade margin• Fresnel zones calculationThis chapter explains the individual steps and an example of link design is given at the end.NOTE - For quick reference you can use the calculator on www.racom.eu12.1.1. Free space loss calculationAs the electromagnetic waves travel through open space they are attenuated. This attenuation is de-scribed as Free-space Loss. The loss depends on the distance travelled by signal and its frequency.Longer distance and higher frequency both mean greater attenuation. Free-space loss can be calculatedthus:FSL = 32.44 + 20log f+ 20log DWhere:FSL free-space loss (dB)ffrequency of the emitted signal (MHz)Dlength of the link (km)2.1.2. Link budget calculationThe goal is to design a link producing a received signal stronger than the receiver's sensitivity at therequired BER (typically 10-6). Since every radio signal in earth atmosphere is subject to fading, somedifference between received signal level under normal circumstances and receiver sensitivity is neededto serve as a fade margin. The minimum value of fade margin can be calculated from the requirementfor link availability (e.g. 99.999% of the time). The required margin depends on the length of the linkas well as other factors such as rain attenuation, diffraction and multipath propagation.If we ignore the additional loss along the path, the received signal strength can be calculated using theformula for signal propagation in free space as follows:PR=PT+GT+GR-FSLWhere1http://www.racom.eu/eng/products/microwave-link.html#calculation_obsahRAy2 Microwave Link – © RACOM s.r.o.12Implementation Notes
PRreceived power level (dBm)PTtransmitted power (dBm)GTtransmitting antenna gain (dBi)GRreceiving antenna gain (dBi)FSL free space loss (dB)PRmust be:PR>PSWhere:PSreceiver sensitivity (dBm)The receiver’s sensitivity defines the minimum level of the received signal at which the receiver is ableto process the signal without losses or affecting the transmitted data (for BER better then 10-6).2.1.3. Fade marginDetermining sufficient fade margin is the most important step in microwave link design. If the marginis too small, the link will be unstable – as a result, sufficient availability of the link or quality of theprovided services cannot be guaranteed. On the other hand, unnecessarily large margin makes thelink more expensive (higher performance, larger and more expensive antennas) and increases thecost of creating the microwave link.The following paragraphs describe the two most significant types of signal strength loss – rain andmultipath attenuation, which are the most frequent along with free space loss. Mutual relation betweenrain and multipath attenuation rules out the possibility that the link could be affected by both types ofattenuation at the same time – these types of attenuation do not add up. To determine the fademargin it is necessary to calculate both rain and multipath attenuation. The larger of the two types ofattenuation determines the value of fade margin. In areas with high precipitation, rain attenuation canbe expected to be more prominent. By contrast, links located in drier climates and little inclination, willsuffer more from multipath attenuation.2.1.4. Rain attenuationFor frequencies of about 10 GHz rain attenuation starts to become increasingly effective. Precipitationis not identical in all areas which is why ITU released a recommendation Rec. ITU-R PN.837-1 forsplitting the world into 15 regions according to precipitation intensity see Fig. 2.1, for more detail Ap-pendix B, Rain zone map. In the areas with higher precipitation greater rain attenuation must be expectedand a greater signal fade margin must be established; see the calculation of link availability.The following properties are inherent to rain attenuation:• It increases exponentially with rain intensity• It becomes significantly larger as the distance travelled increases (>10 Km)• Horizontal polarization causes greater rain attenuation than vertical polarization• Rain outage increases dramatically with frequency and path length13© RACOM s.r.o. – RAy2 Microwave LinkImplementation Notes
Fig. 2.1: Rain zone map, based on Rec.ITU-R PN.837-1Rain attenuation can be calculated using ITU-R outage model, which consists of the following:Obtain the rain rate R0.01 exceeded for 0.01 per cent of the time (with an integration time of 1 min).R0.01 values are defined for 15 rain zones and different time percentages and they are given in ITU-RRecommendation P.837.Tab. 2.1: Rain rate R (mm/h) ITU-R P.837QPNMLKJHGFEDCBAPercentageof time (%)1412542158231.70.62.10.70.5<0.11.04934151174213474.52.44.52.820.80.37265352215122010128685320.196105654033232818201512139650.0311514595636042353230282219151280.0114220014095105704555455441292621140.0031702501801201501005583657870424232220.001Compute specific attenuation γR(dB/km) for the frequency, polarization, specific rain rate using ITU-Rrecommendation P.838.

In regions with higher precip-itation the difference in attenuation is more marked. The microwave links RAy17 and RAy24 use bothpolarizations, hence the need to consider the worse of the two, i.e. horizontal polarization. When ACM15© RACOM s.r.o. – RAy2 Microwave LinkImplementation Notes
is active we recommend using horizontal polarization in the direction with lower data traffic (typicallyup-link).2.1.5. Multipath fadingMultipath fading is another dominant fading mechanism. A reflected wave causes a phenomenon knownas multipath, meaning that the radio signal can travel multiple paths to reach the receiver. Typically,multipath occurs when a reflected wave reaches the receiver at the same time in opposite phase asthe direct wave that travels in a straight line from the transmitter.Multipath propagation gives rise to two kinds of signal degrading effects, i.e., flat fading and frequencyselective fading. Flat fading is a reduction in input signal level where all frequencies in the channel ofinterest are equally affected and is dependent on path length, frequency, and path inclination. In addition,it is strongly dependent on the geoclimatic factor K.To calculate the probability of outage due to multipath propagation of microwave links the ITU-Rprobability model can be used which describes a single frequency (or narrowband) fading distributionsuitable for large fade depths A in the average worst month in any part of the world (based on ITU-RP.530-14). The calculation for detailed link design is given as follows [1]:P0=Kd3.4(1+|εP|)-1.03f0.8×100.00067hL-A/10where:dlink distance (km)ffrequency (GHz)hLaltitude of lower antenna (m)Afade depth (dB)K is geoclimatic factor and can be obtained from:K= 10-4.6-0.0027dN1The term dN1 is provided on a 1.5° grid in latitude and longitude in ITU-R Recommendation P.453.The data are available in a tabular format and are available from the Radiocommunication Bureau(BR). E.g. in Central Europe the values dN1 range from -242 to -362.From the antenna heights heand hr(meters above sea level), calculate the magnitude of the path in-clination │εP│ (mrad) using the following expression:where:dlink distance (km)hr, heantenna heights above sea level (m)RAy2 Microwave Link – © RACOM s.r.o.16Implementation Notes
2.1.6. Fresnel zones calculationThe position of obstacles between points of the bridge can significantly influence the quality of the mi-crowave link. The radio signal doesn't only radiate along the line of sight, but also in the area aroundit, i.e. in the so-called 1st Fresnel zone. Within this zone 90 % of the energy is transmitted between thetransmitter and receiver antenna. This space has the shape of an ellipsoid. If it is disturbed the link haspoorer transmission properties and a higher quality antenna is required. For this reason the positionof the antenna can be just as important as its height above ground. 60 % of the 1st Fresnel zone isconsidered as the most important.rDF1d1× ×Fig. 2.6: Fresnel zoneThe general equation for calculating the first Fresnel zone radius at any point P in between the endpointsof the link is the following:Where:F1first Fresnel Zone radius in metresd1distance of P from one end in metresd2The distance of P from the other end in metresλ wavelength of the transmitted signal in metresThe cross sectional radius of each Fresnel zone is the highest in the center of link, shrinking to a pointat the antenna on each end. For practical applications, it is often useful to know the maximum radiusof the first Fresnel zone.

If you use the maximum performance of antenna with dia-meter of 30 cm, complete the radio formula as follows:PR=PT+GT+GR−FSL = 5 + 32.2 + 32.2 − 129.1 = −59.7 dBFade margin:A= |PS|−|PR| = 79 − 59.7 = 19.3 dBThe resulting fade margin is larger than the required 11 dB. Current legislation in the Czech Republicallows maximum EIRP of +20, i.e. the sum of transmit power and antenna gain at the transmittercan be 20 dB at the most. For 99cm antennas, TX power can be up to 20 - 42 = -22 dB, the resultantequation is as follows:PR=PT+GT+GR−FSL = -22 + 42 + 42 − 129.1 = −67.1 dB19© RACOM s.r.o. – RAy2 Microwave LinkImplementation Notes
Fade margin:A= |PS|−|PR| = 79 − 67.1 = 11.9 dBFade margin is now only 12 dB which corresponds to link availability > 99.99% of the time in a year.Technical literature often gives the minimum fade margin of 20 dB. For very long links (more than10 km) fade margin will, indeed, be approximately 20 dB. For shorter links, however, such largemargin is not necessary. It is helpful to first conduct the calculation above to receive an idea of theattenuation affecting the link.The resultTo achieve the required transmission capacity and link availability for link distance of 4 km, transmitpower -22 dBm and 99 cm antennas were selected for both sides of the link.Sources for Chapter Chapter 2, Implementation Notes:[1] Lehpamer, H.: Microwave transmission network, Second edition, ISBN: 0071701222, McGraw-HillProfessional, 2010.ITU-R recommendation used:• ITU-R P.453-10 – The radio refractive index: its formula and refractivity data• ITU-R P.530-14 – Propagation data and prediction methods required for the design of terrestrialline-of-sight systems• ITU-R P.837-1 and 6 – Characteristics of precipitation for propagation modelling• ITU-R P.838-3 – Specific attenuation model for rain for use in prediction methods• ITU-R P.310, ITU-R P.526, ITU-R P.676, ITU-R P.834, ITU-R P.835RAy2 Microwave Link – © RACOM s.r.o.20Implementation Notes
3. ProductRAy2 microwave links enable transmissions in both bands requiring license fees and those that arefree. They work as a point-to-point link in a full duplex setting with transfer speeds of up to 360 Mbps.Bandwidth can be configured from 1.75 up to 56 MHz. Modulation can be fixed or adaptive and canbe adjusted from QPSK to 256QAM. RAy2 microwave links can also be operated as a Short RangeDevice (SRD).Fig. 3.1: RAy2 – Microwave linkThe link is formed by two FOD (Full Outdoor) units. In the case of links operating in the RAy2-17 andRAy2-24 bands, both units have identical hardware. In the case of links operating in licensed bands,one unit (labeled L) is transmitting in the Lower and receiving in the Upper part of the band. The otherunit (labeled U) is operating vice versa.RAy2 links require the use of external parabolic antennas. Parabolic antennas from different producersare available.Cross polarization - valid only for links operating in the RAy2-17 and RAy2-24 bands:One side of the link uses one polarization for transmission (e.g. horizontal) and the opposite polarizationfor receiving (e.g. vertical). The other side of the link is turned by 90°. It therefore transmits and receivesusing opposite polarizations with respect to the other unit.21© RACOM s.r.o. – RAy2 Microwave LinkProduct
3.1. MountingFig. 3.2: RAy2 Microwave link – antenna and FOD unitThe antenna is attached to the mast using a holder adjustable in two planes. The RAy2 unit is thenmounted on the antenna.There are two possible mounting positions – for horizontal and vertical polarization. Installation andadjustment of the holder is described in the Section 6.2, “Antenna mounting”.NoteThe RAy2-10 and RAy2-11 units must be mounted with the same polarization while theunits RAy2-17 and RAy2-24 must be mounted with reverse polarity, see Cross polarization.3.2. ConnectorsEach unit is equipped with the following interfaces:■ ETH1+POE – Gigabit metallic Ethernet port. This port is capable of powering the unit with anyPower over Ethernet power source working according to IEEE 802.3at standard.■ ETH2 – Slot for user exchangeable SFP module. A wide range of optical modules is available. Bothsingle or dual mode transceivers can be used. An SFP module with metallic RJ45 interface canalso be used.The SFP status LED is located just next to the slot.■ P – DC power connector.HW button for service purposes.■ S – USB service connector.RSS voltage output connectors.ImportantIt is strongly recommended to use a high quality SFP module. The SFP modules listed inAccessories are thoroughly tested by RACOM and are guaranteed to function with RAy2units. It is possible to use any other SFP module, but RACOM cannot guarantee they willbe completely compatible with RAy2 units.RAy2 Microwave Link – © RACOM s.r.o.22Product
The SFP status LED function: The LED status is controlled directly from the SFP module. Its functionis specific for each SFP module. The typical behaviour is an indication of the received signal strength.Should the signal be in the proper power range (not too strong and not too weak), the LED is shining.Fig. 3.3: Connectors covered Fig. 3.4: Connectors uncoveredImportantIt is recommended that the ETH cable should be grounded at both ends of the connection.For example, the connector CON-RJ45-UBNT-CAT6 and ETH socket on the control panelshould have a grounded sheath as should the connection to the RAy2 unit.All bushings and plugs (including the original plugs in the ports) must be fitted with O-ringsand carefully tightened. Otherwise, the unit is not protected against moisture intake and cannot offer guaranteed functionality.For detailed description see Connectors and Start up.3.3. Power supplyThe microwave unit can be powered either by PoE or a DC power source:•Standard PoE plus (IEEE 802.3at) power source connected to the “ETH1+POE” connector.Supported voltage range is 40 — 60 V, distances up to 100 m. Internal RJ45 pins wiring is :○ (V+) ... 1,2,4,5○ (V-) ... 3,6,7,8It is possible to use all 8 pins or only 4 pins. Use:○ either 4,5 (V+) and 7,8 (V-)○ or 1,2 (V+) and 3,6 (V-)○ or both simultaneously•Any kind of DC power source connected to “P” 3-pin connector.Supported voltage range is 20 — 60 V.ImportantThe microwave unit doesn't support a combination of both power supplies. Only one powersupply can be connected at any one time.23© RACOM s.r.o. – RAy2 Microwave LinkProduct
The internal DC power source uses galvanic separation. If the galvanic separated power source isused and the DC power line needs to be grounded (either positive or negative wire), the middle pin ofthe 3-port DC connector can be used to make a connection between ground and the respective powerwire, see Grounding options (d),(e). If grounding is required it should only be made in one of the followingways: on the DC power source side or using the 3-port DC connector plugged into the unit.The next figure shows all available grounding options. We recommend the use of a galvanic separatedpower source and no additional DC grounding - see Fig. 3.5, “Grounding options” version c).+DC +RAy2GND+DC +RAy2GND+DC +RAy2GND+DC +RAy2GND+DC +RAy2GNDa)b)c)d)e)Fig. 3.5: Grounding optionsGND +HW buttonFig. 3.6: Power supply connector 1Fig. 3.7: Power supply connector 2RAy2 Microwave Link – © RACOM s.r.o.24Product

5. Step-by-step GuideThe following chapters will guide you step by step through preparation, installation and activation ofthe RAy2 link:• Pre-installation check out•Installation (Chapter 6, Installation)•Advanced configuration (Chapter 7, Configuration)•Troubleshooting (Chapter 9, Troubleshooting)Pre-installation ChecklistFamiliarise yourself with the controls and prepare your configuration ahead of the installation of thelink on the mast tube.Both units (without antennas) can lie on a desk with flanges running parallel and facing up at an angle;on a non-metal desk they can also face downward. In the case of units RAy2-17 and RAy2-24 turn theunit holders so that they are roughly perpendicular to each other. In the case of units operating in licensedbands (RAy2-10, RAy2-11), turn unit holders so that they are roughly parallel to each other. Use anethernet cable to connect each of the units to a PoE source and connect a PC to one of them for con-figuration.Take the following steps to establish a connection between the PC and RAy2 and perform a basicsetup.Fig. 5.1: Link Configuration (RAy2-17, perpendicular holders)RAy2 Microwave Link – © RACOM s.r.o.36Step-by-step Guide
WarningDuring operation, never bring the waveguides of the stations close to each other. There isa risk of damaging sensitive input circuits.5.1. Service accessThe RAy2 link is supplied with a default configuration of access parameters:Unit L has the service IP address 192.168.169.169 and mask 255.255.255.0,Unit U has the service IP address 192.168.169.170 and mask 255.255.255.0,access is allowed over HTTP, HTTPS or SSH,the username is admin and the password is also admin.On your PC setup an IP address that is within the mask, e.g. 192.168.169.180.Then open the https configuration interface, e.g.https://192.168.169.169Other access options are described in the chapter Configuration - Link settings - Service access of thismanual.When connection has been established, use the Service access menu to customise access parameters.Default IP addresses should be replaced with well-chosen operating addresses. Leaving default ad-dresses in place can lead to network problems later.The menu contains parameters for the entire link, both for the Local and remote Peer units. If a connec-tion has been established, both sets of parameters have been set. While working with an isolated unit,only Local parameters are functional for the currently connected unit.NoteIf the link is OK and there are no parameters shown of the station Peer, it is necessary toclick on Refresh.Follows the description of basic settings. After entering values on the screen always save the contentby clicking on Apply.NoteIf there is any problem with https certificate after completing the firmware upgrade, pleasesee the Annex Https certificate for further steps.37© RACOM s.r.o. – RAy2 Microwave LinkStep-by-step Guide

Menu Link - Service access - Users•Edit - enter the menu.•New password – choose a password and enter it.•Confirm password – enter the password again to confirm.Fig. 5.4: Configuration menu Link settings – Service access – Services5.1.4. Menu Maintenance - Feature keysThe firmware of the microwave link is capable of controlling the maximum user data speed. The defaultuser speed without the feature key is the minimum for the respective hardware unit. The feature keyto assign the maximum user data speed, should be installed prior to physical installation. For furtherdetails see the section called “Feature keys”.5.2. Basic link configurationDefault radio parameters depend on the specific type of link and the specific channel allocation table.Channels are typically set in the lower part of the band, the smallest bandwidth, QPSK modulation,and low power. Both units in the pair should be capable of immediate communication. If it is possible towork with these radio parameters at the installation location, the link can be activated. On an operatinglink the required operating parameters can then be set up.If a change in the parameters is necessary, it is done in the menu Link settings – Radio and saved byclicking Apply. This applies when working on both units simultaneously if they are connected, otherwiseeach unit is configured individually. When configuring units individually, pay attention to correct settingsof duplex pair for channels TX and RX. For example, if one station has TX channel L1, then the secondstation must also have the channel RX L1.5.3. Link testVerify the functionality of the radio link:•Switch in screen Status - Brief.•Status Bar displays Link: Ok.RAy2 Microwave Link – © RACOM s.r.o.40Step-by-step Guide
If the alarm message appears at Local or Peer, this doesn’t necessarily mean there is a problem.The message indicates that the limit at any of the monitored parameters has been exceeded. Es-sential is the Link: Ok message on the status bar.•The Status screen contains values for both Local and Peer units. N/A next to Peer indicates thatthe data from the Peer unit has not been transferred. If Link is Ok, simply click Refresh at the bottomof the screen and Peer data will be updated.•Menu Status – Detailed – Radio indicates link RSS and SNR values, in case of ACM also the selectedmodulation and Netbitrate. If the ATPC function is enabled (menu Link settings – Radio) it also in-dicates instantaneous / max. allowed power and for SNR and RSS values it indicates immediate /target value size.•Menu Tools – Live data – Bar indicators displays current size of RSS, SNR and BER.•Menu Tools – Ping allows you to send a ping test to the selected IP address.Try out the possibility of modulation:•Modulation ACM. In menu Link settings – Radio enable ACM. Set the TX modulation parameter tothe required maximum value. In menu Status – Brief – Radio you can monitor (Refresh or Start)changes in used modulation based on the instantaneous SNR signal quality. The status and qualityof modulation is demonstrated well in menu Tools – Live data – RX constellation diagram, hit Refresh.•To set a fixed modulation go to Link settings - Radio, switch off ACM and set the TX modulation toa value from the range of QPSK through 256-QAM based on the results of the previous test. If youchoose modulation higher than allowed by SNR, the connection will be lost. Status Link will lose itsOk value. Both units will need to be moved closer to resume the link. If this is not possible, use theethernet to access each unit individually and set the basic modulation QPSK. You can monitor thequality of the received signal under Tools – Live data – RX constellation diagram.Verify the functionality of the entire link:• If possible, connect user devices to both RAy2 units over PoE and test mutual communication.• Another way of testing this is to connect a PC to the other unit and send a ping from one PC to theother.• The minimum variant of this test is to use an ethernet cable connection from the PC connected tothe local RAy2 to the PC connected to the remote RAy2 and test communication between bothunits over ethernet. This will verify ethernet functionality.Prepare installation configuration:•Bandwidth e.g. 3.5 MHz. To get the highest possible receiver sensitivity, set the bandwidth as narrowas possible according to specific frequency band.• TX channel: Use your allocated channel. If you don't have allocated channel yet, use for examplechannel L1.• RX channel will setup automatically when channel lock activates.• Set TX modulation QPSK to get the highest possible sensitivity.• Set RF power according to selected antenna and according to individual frequency licence. Set theoutput power as high as possible.• Set a new users access passwords.• Record the access parameters from the Service access menu, especially the IP addresses.• Restart by interrupting the power supply to verify that the parameters are stored correctly and thelink works.After this preparation phase you can continue to install your devices in a working environment.41© RACOM s.r.o. – RAy2 Microwave LinkStep-by-step Guide
6. Installation6.1. Line of sight testBefore you install the device to a mast tube, verify visually that the view in the direction of the remoteunit is unobstructed.Line of sight considerations:• Free Fresnel zones. Signal needs space wider than the diameter of the antenna.• Trees at the lower end of the Fresnel zone. They will be taller in a few years.• Possible building development.•Objects in the close proximity of the antenna such as edges of other antennas, their mounting racks,edges of the roof.6.2. Antenna mounting6.2.1. Mounting methods• Mounting on the mast tube can be achieved by:○ right-side mounting or○ left-side mounting• Mounting the FOD unit for antenna polarization can be achieved using:○ horizontal RX polarization mounting or○ vertical RX polarization mountingIn both cases mount the unit with the connectors facing downwards at an angle.Fig. 6.1: Horizontal RX polarization– see the arrow signFig. 6.2: Vertical RX polarization– see the arrow signRAy2 Microwave Link – © RACOM s.r.o.42Installation
Fig. 6.3: Left-side mounting– horizontal RX polarizationFig. 6.4: Right-side mounting– vertical RX polarizationFig. 6.5: Right-side mounting – horizontal RX polarization43© RACOM s.r.o. – RAy2 Microwave LinkInstallation
Changing the mounting methodAn antenna bracket is supplied as standard partly assembled, and ready for right-side mounting.On changing the Jirous antenna bracket for left-side mounting the adjustment bolt (part No. 11) andswivel bolt (part No. 6) need to be unscrewed, then shift the bracket body (part No.5) to the other sideof clamp plate (part No. 4), (do not turn upside down) and then insert bolt (part No. 6) into the secondhole on the mounting plate holder and through the same hole on the clamp plate and secure in placewith the nuts. The adjustment bolt (item No. 11) and nuts are switched to the other side of the clampplate (part No. 4). It is also necessary to switch the hanging bolt (part No. 7) on the antenna mountingplate to the second hole so that after switching sides with the antenna it is on the top again.In the case of the antenna when changing the method of mounting from right-side to left-side it is onlynecessary to rotate the plastic cover of the antenna. This is not only important from an aesthetic pointof view, so that the RACOM logo is not upside down, but also because there is a discharge channelon the lower edge of the dish (except for ø380 mm dishes).Fig. 6.6: Changing the mounting methodWhen changing the polarization from horizontal to vertical only the FOD unit needs to be turned through90° around the central antenna pin by unscrewing the four bolts on the dish using a No. 6 Allen key.ImportantThe RAy2-17 and RAy2-24 links are equipped with a polarization duplexer and work in bothpolarizations simultaneously, see Cross polarization. One side of the link must thereforebe installed in vertical polarization and the other in the horizontal polarization.RAy2 Microwave Link – © RACOM s.r.o.44Installation
6.2.2. Mounting the FOD unit on the antennaRAy2 microwave bridge equipment is generally supplied as several component parts packaged separ-ately in a box.• Two parabolic antennas with assembled mounting plates. There are also 4 screws in a small plasticbag in the box.• Two brackets for mounting the antenna to the mast.• Two FOD stations, each separate in a box, in a single package.• Other accessories based on the order placed (for more detailed information see chapter Chapter 4,Accessories)A No. 17 spanner and a No. 6 Allen key are required for mounting the mechanical parts of the antenna.Spanner No. 17 serves for precisely setting the direction of the antenna. Both spanner and key can befound in the RAy Tool set for installing RAy2 microwave bridges.It is advisable to lightly lubricate the retaining screws eg. by the supplied grease.Fig. 6.7: Close up image of the mounted bracket showing numbered partsa. Prepare the antenna bracket based on the diameter of the mast tube. For smaller diameters facethe bent part of the saddle plate (part No. 3) inwards. For larger diameters it should face outwards.Screw the bolts (part No. 1) into the clamp plate (part No. 4) so that they protrude approx. 1 cmthrough the clamp plate. Clamp the saddle plate to the mast by tightening the nuts (part No. 2) onthe bolts.Fig. 6.8: Position of the saddle plate forø 40–80 mmFig. 6.9: Position of the saddle plate forø 65–115 mm45© RACOM s.r.o. – RAy2 Microwave LinkInstallation
b. Slide the antenna bracket onto the mast tube and clamp to the mast by tightening the nuts.Recommendation: Keep the gap between the two saddle plates (part No. 3) as wide as possible,so the horizontal angle adjustement screw can fit in this gap. The range of horizontal adjustementis consequently wider. This has a bigger effect when the mast diameter is smaller.Fig. 6.10: Attaching the bracket to the mast tube Fig. 6.11: Bracket on the mast tubec. Screw the hanging bolt (part No. 7) into the upper hole of the mounting plate so that the antennacan be hung on the mounting plate holder. Hang the antenna on it and tighten the lower bolt. (partNo. 8)Fig. 6.12: Hanging the bolt on the holder Fig. 6.13: Correct position of the mounting plateRAy2 Microwave Link – © RACOM s.r.o.46Installation
d. Tighten both bolts to the plate before continuing with installation to prevent any unnecessarymovements of the equipment. Before precisely adjusting the vertical direction of the antenna uponcompleting installation it will be necessary to unscrew them again as the lower bolt (part No. 8)passes through the adjustment block and the upper one (part No. 7) serves as the axis of rotation.Fig. 6.14: Tightening the upper bolt tothe mounting plateFig. 6.15: Tightening the lower bolt tothe mounting platee. Before installing the FOD unit on the antenna first unscrew the 4 bolts on the back of the antennaenough so that the unit can be slid on to them. Then check whether the "O" ring is correctly fittedon the antenna pin, and make sure it is not damaged and has been lubricated with grease – seeSection 6.2.3, “Lubrication and preservation of the antenna pivot”. Then remove the protectiveplastic cover from the central pin of the antenna and fit the FOD unit to it carefully so as not todamage the "O" ring. Secure it in place with the four bolts. Carefully ensure the correct polarizationof the antenna – see Section 6.2.1, “Mounting methods”. Finally tighten the bolts with a No. 6 Allenkey.Fig. 6.16: Dish before installing the FOD unit Fig. 6.17: Tightening bolts on the FOD unit47© RACOM s.r.o. – RAy2 Microwave LinkInstallation
f. The precise horizontal direction the antenna is pointing in can be adjusted using the bolt with twonuts (part No. 10 and 12). Once the direction has been set the antenna is fixed in place by tighteningthe nuts against the bracket to prevent further movement of the antenna. The vertical direction theantenna is pointing in can be adjusted by turning the fine adjustment bolt (part No. 9) by thebracket mounting plate. After selecting the correct direction the position is secured by tighteningthe bolt – see point d. (part No. 7 and 8). The correct position in both directions is found by monit-oring RSS voltage, see Section 6.5.2, “Directing antennas”.Fig. 6.18: Horizontal adjustment of theantenna directionFig. 6.19: Vertical adjustment of theantenna directiong. After pointing the antenna in the right direction tighten the bolts on the bracket on the axes of rotation(part No. 6 and 11). Then check again that all other bolts have been sufficiently tightened. We cannow proceed to connect the FOD unit to the user network.Fig. 6.20: Tightening the axis at the fineadjustment boltFig. 6.21: Tightening the axis at the bracketRAy2 Microwave Link – © RACOM s.r.o.48Installation
6.2.3. Lubrication and preservation of the antenna pivotBefore fitting the FOD unit bush onto the antenna pivot ensure that the "O" ring (part No. 1) is in thecorrect position. It is also essential to prevent moisture getting in between these two parts. This moisturecould cause oxidation which would complicate disassembly of this mechanical coupling in the future.For this reason we need to treat these surfaces with the grease which is supplied in the box marked"SILIKONOVE MAZIVO". If you use a different grease for lubrication then it should be a Teflon or asilicon grease.Fig. 6.22: Grease points on the antenna pivot and FOD unit bushGrease the internal area of the bush on the FOD unit (2) and the "O" ring (1) with a thin even layer thatallows the pin to slide easily into the bush without damaging the "O" ring. Grease the area beyond the"O" ring on the antenna pin (3) with a thicker layer so that it fills the gap caused by the play betweenthe pin and the bush (max. 0.1 mm/ø) thus preventing moisture getting in. Installation should be carriedout according to the antenna installation description – see point f of this description.The tub with grease is supplied with the RAy2 units.6.2.4. Flexible waveguideAny type of antenna may be connected to the RAy2 unit using a flexible waveguide. Flexible waveguidemounting kit can be ordered as an accessory part.Fig. 6.23: Flexible waveguide assembly49© RACOM s.r.o. – RAy2 Microwave LinkInstallation
6.3. Connectors assemblyThe FOD communication unit can be connected to the user network by metallic or fibre Ethernet cable.The unit is equipped with those connectors:■ ETH1+POE – Gigabit metallic Ethernet port. This port can power the unit with any Power overEthernet power source working according to IEEE 802.3at standard.■ ETH2 – Slot for user exchangeable SFP module. A wide range of optical modules is available. Bothsingle or dual mode transceivers can be used. The SFP module with metallic RJ45 interface canbe used as well. Please see the Important notice.The SFP status LED is located just next to the slot.■ P – DC power connector.HW button for service purposes.■ S – USB service connector.RSS voltage output connectors.Fig. 6.24: FOD communication unit connectorsImportantBefore connecting the FOD communication unit to the supply (to the user network) the FODunit must be grounded according to Section 6.4, “Grounding”.RAy2 Microwave Link – © RACOM s.r.o.50Installation
Assembly procedure:Fig. 6.25: Bushing and connector assemblyFig. 6.26: Bushing incl. lengthening and connector assembly• Put on the cable: the nut No.1, rubber sealing No.2, bushing No.3 and O-ring No.4.• Attach the appropriate connector No.5 to the cable.• Plug the connector No.5 into the RAy2 unit.• Screw the bushing No.3 with the sealing O-ring into the RAy2 unit.• Move the rubber sealing No.2 along the cable to fit in the bushing. Screw the nut No.1 on bushingNo.3.• (If you use extension ring No. 6 lubricate its thread with grease.)Disassembly procedure:• Release the nut No.1• Remove the rubber sealing No.2• Unscrew the bushing No.3 with O-ring No.4 (and extension No.6 with O-ring No.7).• Remove the connector.51© RACOM s.r.o. – RAy2 Microwave LinkInstallation
Fig. 6.27: Bushing including long lengtheningAll necessary parts are delivered as an accessory SET-RAY2-CON-B. If the lengthening is neededuse the extension SET-RAY2-EXT35 containing the parts No.6 and No.7 or use the longer extensionSET-RAY2- EXT-F50.The rubber sealing is delivered with three different internal diameters to fit different cable diameters.The rubber is diagonally cut to enable sealing of cables with preinstalled connectors.ImportantAll bushings and plugs (including the original plugs in the ports) must be fitted with O-rings and carefully tightened. Failure to do so may result in moisture accessing the in-ternal workings. In such a situation the functionality cannot be guaranteed.•• Before screwing extension ring (part No.6) into the RAy2 housing, lubricate its threadwith grease.• When using other bushing or connector than the delivered there is a danger of bad sealor damaging the connector. Interior space can be small.6.4. GroundingThe lightning and overvoltage protection system example, designed in accordance with regulation CSNEN 62305.1. Where possible the antenna should be located in an LPZ 0B protection zone with the use of alocal or artificial air termination device for protection against direct lightning strikes.2. When meeting conditions for ensuring electrical insulation (distance from the lightning conductor)in accordance with article 6.3, it is not recommended to ground the load-bearing structure andantenna to the external air termination network. Grounding should be attached to the protectivesystem of the internal LV wiring or grounded internal structures using a CYA 6 mm2bonding con-ductor , see Fig. 6.28, “Grounding installation 1”RAy2 Microwave Link – © RACOM s.r.o.52Installation

3. If it is not possible to set up conditions of electrical insulation in accordance with article 6.3 we re-commend connecting the load-bearing structure at roof level to the external air termination networkvia an 8mm diameter FeZn conductor and shielding the data cable before entry to the buildingwith a grounding kit and CYA 6 mm2conductor to the bonding bus, and if not already set up thenalso to the external air termination network, see Fig. 6.29, “Grounding installation 2”4. If there is not an external LPS on the building we recommend routing lightning current through an8mm FeZn conductor to a common grounding system, or to a separate grounding electrode witha ground resistance up to 10 Ω.5. For limiting the overvoltage transferred over the data cable and into the building we recommendfitting surge protection at the interface between zones LPZ 0 and LPZ 1 connected via a CYA 4mm2conductor to the same grounding point as the antenna or the antenna mast.6. We recommend protecting the PoE power supply from overvoltage on the LV side with suitableclass D surge protection.The RAy2 unit is grounded to the flange at the fixing screws using an M8 screw. An insulated coppercable with a minimum cross-section of 6 mm2terminated with a terminal lug is used as a protectiveconductor. The conductor should have a green/yellow plastic cover along its whole length. Forgrounding a RAy grounding kit can be ordered as an accessory (see Chapter 4, Accessories) containinga grounding terminal ZSA16, 40 cm grounding strip 15 mm wide, and 100 cm of cable with groundinglugs. For instructions on installing terminals see the datasheet RAy grounding kit1. A qualified personmust install the antenna.Racom supplies surge protection for installation on Ethernet cables entering buildings. For more detailssee Surge protection2.Additional safety recommendations• Only qualified personnel with authorisation to work at heights are entitled to install antennas onmasts, roofs and walls of buildings.• Do not install the antenna in the vicinity of electrical wiring. The antenna and bracket should notcome into contact with electrical wiring at any time.• The antenna and cables are electrical conductors. During installation electrostatic charges maybuild up which may lead to injury. During installation or repair work to parts of the antenna lead,bare metal parts must be temporarily grounded.• The antenna and antenna cable must be grounded at all times. See Section 6.4, “Grounding”.• Do not mount the antenna in windy or rainy conditions or during a storm, or if the area is coveredwith snow or ice.• Do not touch the antenna, antenna brackets or conductors during a storm.1http://www.racom.eu/download/hw/ray/free/eng/07_prislusenstvi/ZSA16-en.pdf2http://www.racom.eu/eng/products/microwave-link.html#accessoriesRAy2 Microwave Link – © RACOM s.r.o.54Installation

6.5. Start upConnect a power supply to the installed FOD unit and connect the configuration PC. Use an internetbrowser (such as Mozilla Firefox) to enter the configuration menu.6.5.1. Noise on the siteThis is particularly true for installation of links working in free bands, where the user has no securedfrequency.Analyse the level of noise in the individual channels using the spectrum analyzer under Tools – Livedata – Frequency spectrum analyzer. If necessary adjust the choice of working channel on the basisof the results.While doing so respect the rule that in one location all units emit a signal in the Upper part of the rangeand receive it in the Lower part of the range, or the other way round. A transmitter must not be installedin the part of the spectrum where other units function as receivers.6.5.2. Directing antennasIf it is possible, use a narrow channel, low modulation and high power for the first antenna directingalignment. Working on both ends of the link simultaneously is favourable. Connect a voltmeter to theconnectors and observe RSS changes in 2 V DC range. A stronger signal corresponds to lower voltage.Alternate units on both sides and slowly adjust the antenna vertically and horizontally to find the positionwith the strongest reception. At the same time look for the main signal maximums. To differentiatebetween the main and the side maximums refer to the Main and side lobes paragraph.RSS measurementFor correctly setting the bridge and positioning it in the right direction it is advisable to connect a PCand use the diagnostic capabilities of the RAy2 station. In uncomplicated cases it is enough to connecta voltmeter via connectors and adjust to the lowest indicated voltage. Voltage is calibrated accordingto signal strength. E.g.:RSS -65 dBm corresponds to voltage 0.65 V,RSS -80 dBm corresponds to voltage 0.80 V etc.Fig. 6.38: RSS connectorsFig. 6.39: RSS connectors- connecting a voltmeter57© RACOM s.r.o. – RAy2 Microwave LinkInstallation
Main and side lobesDirectional antennas have a specific angle within which radio waves can be transmitted or received(Angle of Tx/Rx).The strongest signal is emitted in a forward direction; the main lobe is a graphical representation of itsdirection of travel and strength.However signals are also emitted and received from unwanted directions through side lobes. In receivingantennas this is a highly significant factor contributing to the level of interference in a radio network(See Fig. 6.40, “Antenna lobe diagram”).Fig. 6.41, “Signal strength graph” provides an indication of comparative signal strength from differentbeams emitted from a directional antenna.AntennaAngle of T / Rx xMain lobeBack lobeSide lobes090-90000Fig. 6.40: Antenna lobe diagram0-180Angle (Degrees)Directivity (dBi)Main lobeSide lobesSide lobelevel18030 60-60 -30Fig. 6.41: Signal strength graphPlacing the antennas to the correct antenna alignment is very important to ensure the strongest signalis received:Fig. 6.42: Correct alignment diagramRAy2 Microwave Link – © RACOM s.r.o.58Installation

6.5.3. Link testBasic parameters of the link are shown in the menu Status – Brief, its quality is characterized by RSSand SNR. Values on Status screens can be refreshed manually by pressing the Refresh button orin real time with a period of several seconds after activating the Start button. Press the Stop button toterminate the periodic refresh of values.The RSS, SNR and BER values can also be viewed on the screen Tools – Live data – Bar indicators.After pressing the Start button, values will be refreshed with a period of one second.After installation, it is good to reset the statistics using the Clear stats button in menu Status – Detailed.This allows easier diagnostics of the link’s reliability over time.6.5.4. Parameters setupAfter both antennas have been aligned, setup operation parameters for the link. In the case of linksoperating in the free band, setup the parameters based on survey results from the tool Tools – Livedata – Frequency analyser. In the case of links operating on a licensed band, setup the parametersbased on the assigned license:• Bandwidth• Channel Selection (TX / RX channel)•Modulation (TX modulation) – ACM is recommended. When selecting fixed modulation it is necessaryto account for the fade margin. If fixed modulation is setup close to a possible maximum, then adeterioration in RSS could endanger the link both for data transfer as well as service access.• Transmit power (TX power), or ATPC• Verify and record IP addresses• Define access channels – https / telnet / ssh / ssh with password• Check the users password settings.Restart both units by interrupting their power supply and verify the status of the link. This verifies thatall parameters have been stored correctly in the memory.Select Tools – Maintenance – Backup – Settings (Local & Peer) - Download and save the configurationto backup file “cnf_backup.tgz”.This completes the installation.

7.4.3. Service accessServicesAccess routes for link configuration.Fig. 7.9: Menu Link settings – Service access – ServicesThere are two modes of accessing the internal management system of the microwavelink: standard and directServicechannelstandard:Both units are configured with the separate IP addresses, Netmasks, Gateways andManagement VLANs. IP addresses of both units doesn't have to belong in to thesame sub-net. The Internal VLAN is required to encapsulate the internal service trafficbetween both units of the microwave link. There are additional internal service ad-dresses used for this internal service traffic (see IPv4 address - Local section forfurther details).RAy2 Microwave Link – © RACOM s.r.o.72Configuration
direct:Both units are configured with the separate IP addresses but with the same Netmask,Gateway and the Management VLAN. IP addresses of both units must belong into the same sub-net. There is no need for Internal VLAN to handle the internal servicetraffic between both units of the microwave link. No additional internal service ad-dresses exist.NOTE: It is strongly recommended to use Management VLAN to encapsulate andprioritize the management traffic when the direct mode is selected. If the ManagementVLAN is not used (while in direct mode), the internal service traffic is NOT prioritized.Service IP address, by default 192.168.169.169 for L unit and 192.168.169.170 for Uunit. Four addresses 169.254.173.236/30 are used for internal communication. MustIPv4 address- Localnot be used as service IP address. Those four addresses are not used while Servicechannel is set to direct mode.UnknownIP address For easier identification of service IP address, RAy is equipped with LLDP protocol. Thisprotocol sends a broadcast every 60 seconds with the following information:IP addressManagement addressSerial numberSystem DescriptionType (e.g. RAY2-17-L)Chassis SubtypeIEEE 802.1 - Port and Protocol VLAN IDPort and Protocol VLAN Identifier: (e.g. 300 (0x012C))but only if Management VLAN is enabledThe message can be recorded and converted into a readable form using an LLDP client.A suitable tool for this purpose is Wireshark IP traffic analyzing tool, with free licensesavailable for both Windows and Linux. To locate the message easily, use the Capturefilter "ether proto 0x88cc” in Wireshark.Management address of the Peer station. This address has to be set up when theService channel is set to direct mode.IPv4 address- PeerMask for service access, 24 by default.NetmaskDefault gateway for service access; empty by default.GatewayEnables access via VLAN management. Blocks access for https, ssh and telnet con-figuration via untagged packets (without VLAN) making only VLAN access possible.VLAN management is off by default.WARNING:By enabling VLAN management, ALL accesses are blocked for configuration usingnormal (untagged) LAN! During tests, you may enable VLAN management on oneManagementVLANunit only (if the Service channel = standard). Then it is possible to access the link viaLAN and VLAN either directly or via radio link.VLAN management id, by default 1.

(IEEE 802.3 Clauses 28 and40)1000BASE-X Fiber Auto-Negotiation (IEEE 802.3 Clause 37)SGMII Auto-Negotiation (Cisco specification)Auto-Negotiation provides a mechanism for transferring information from the localunit to the link partner to establish speed, duplex and Master/Slave preferenceduring a link session.Auto-Negotiation is initiated upon any of the following conditions:Power up resetHardware resetSoftware resetRestart Auto-NegotiationTransition from power down to power upThe link goes downThe 10/100/1000BASE-T Auto-Negotiation is based on Clause 28 and 40 of theIEEE 802.3 specification. It is used to negotiate speed, duplex and flow controlover CAT5 (or higher) UTP cable. Once Auto-Negotiation is initiated, the devicedetermines whether or not the remote device has Auto-Negotiation capability. Ifso, the device and the remote device negotiate the speed and duplex with whichto operate.If the remote device does not have Auto-Negotiation capability, the device usesthe parallel detect function to determine the speed of the remote device for100BASE-TX and 10BASE-T modes. If a link is established based on the parallel93© RACOM s.r.o. – RAy2 Microwave LinkConfiguration
detect function, it is then required to establish the link at half-duplex mode only.Refer to IEEE 802.3 clauses 28 and 40 for a full description of Auto-Negotiation.1000BASE-X Auto-Negotiation is defined in Clause 37 of the IEEE 802.3 specific-ation. It is used to auto-negotiate duplex and flow control over fibre cable.If the PHY enables 1000BASE-X Auto-Negotiation and the link partner does not,the link cannot linkup. The device implements an Auto-Negotiation bypass mode.SGMII Auto-Negotiation. SGMII is a de-facto standard designed by Cisco. SGMIIuses 1000BASE-X coding to send data as well as Auto-Negotiation informationbetween the PHY and the MAC. However, the contents of the SGMII Auto-Negoti-ation are different than the 1000BASE-X Auto-Negotiation.WARNING: If one device provides Auto-negotiation and the other works with amanual link parameters settings (i.e. without Auto-negotiation) the link operatesin half-duplex mode. If the manual settings is set to full-duplex, the Out collisionsmay occur.Speed / duplex Ethernet link speed and duplex mode can be selected. Both parameters can beeither auto negotiated or set manually. When the Auto negotiation parameter isdisabled, only manual setting of the speed and duplex is possible. In most casesit is better to enable the auto negotiation and use "auto / auto" speed and duplexsettings.There are two possibilities to force the link to operate in specific speed and duplex:Auto negotiation enabled. Select the desired Speed / duplex. The auto negoti-ation process advertises only this specified link mode. The link partner is askedto use it.Auto negotiation disabled. Select the desired Speed / duplex. The link is set tothis specified link mode. The link partner has to be set manually to the samemode.Flow control The flow control mechanism is handled by sending Pause frames to the connecteddevice. There are several modes of Pause frames generation:Pause frames disabled.no pausePause frames transmission and reception enabled.symmetricPause frames transmission enabled, reception disabled.asymmetric(send)Pause frames reception enabled, transmission disabled.asymmetric(receive)Auto-Negotiation has to be enabled to enable Pause frames sending and receiving.Forceflow control If the Auto-Negotiation is disabled and Flow control is required, the Force flowcontrol parameter can be used.

Both modes enable the PHY to wake up on itsRAy2 Microwave Link – © RACOM s.r.o.94Configuration
own by detecting activity on the Ethernet cable. The energy detect modes onlyapply to the copper media.In the first sense mode, if the PHY detects energy on the line, it starts to Auto-Ne-gotiate sending FLPs (Fast Link Pulse) for 5 seconds. If at the end of 5 secondsthe Auto-Negotiation is not completed, then the PHY stops sending FLPs and goesback to monitoring received energy. If Auto-Negotiation is completed, then the PHYgoes into normal 10/100/1000 Mbps operation. If during normal operation the linkis lost, the PHY will re-start Auto-Negotiation. If no energy is detected after 5seconds, the PHY goes back to monitoring received energy.In sense pulse mode, the PHY sends out a single 10 Mbps NLP (Normal Link Pulse)every one second. Except for this difference, this is identical to the previous mode(sense) operation. If the device is in sense mode, it cannot wake up a connecteddevice; therefore, the connected device must be transmitting NLPs.

Tagged frames use an Ether Type of 0x8100.normalPorts that are expected to be connected to standard Ethernet devicesshould use this mode.Inactive options are not required.DSAProvider mode uses user definable Ether Types per port (see Ethertype parameter) to define that a frame is Provider Tagged. Ports thatproviderare connected to standard Provider network devices, or devices thatuse Tagged frames with an Ether Type other than 0x8100 should usethis mode.Frames that ingress this port with an Ether Type that matches the port'sEther Type parameter will be considered tagged, will have the tag'sVID and PRI bits assigned to the frame (i.e. they will be used forRAy2 Microwave Link – © RACOM s.r.o.96Configuration
switching and mapping), and will have the Provider Tag removed fromthe frame. If subsequent Provider Tags are found following the 1stProvider Tag, they too will be removed from the frame with their VIDand PRI bits being ignored. Modified frames will be padded if required.Frames that ingress this port with an Ether Type that does not matchthe Ether Type parameter will be considered untagged. The ingressingframes are modified so they are ready to egress out Customer ports(Normal Network Frame Mode ports) unmodified.Frames that egress this port will always have a tag added (even if theywere already tagged). The added tag will contain this port's Ether Typeas its Ether Type. The PRI bits will be the Frame Priority FPri assignedto the frame during ingress. The VID bits will be the source port's DefaultVID bits (if the source port was in Normal Network mode), or the VIDassigned to the frame during ingress (if the source port was in Providermode).Valid only for the "p5 CPU" port.ethertype DSA Ether Type DSA mode uses standard Marvell DSA Tagged frame in-formation following a user definable Ether Type (see Ether type para-meter). This mode allows the mixture of Normal Network frames withDSA Tagged frames and is useful on ports that connect to a CPU.Frames that ingress this port with an Ether Type that matches the port's"Ether Type" will be considered DSA Tagged and processed accordingly.The frame's Ether Type and DSA pad bytes will be removed so theresulting frame will be ready to egress out Marvell DSA Tag Mode portsunmodified. Frames that ingress this port with a different Ether Typewill be considered Normal Network Frames and processed accordingly.Marvell DSA Tag control frames that egress this port will always getthe port's "Ether Type" inserted followed by two pad bytes of 0x00 beforethe DSA Tag. Marvell DSA Tag Forward frames that egress this portcan egress just like the control frames (with the added Ether Type andpad) or they can egress as if the port was configured in Normal Networkmode. This selection is controlled by the port's Egress Mode bits above.Frame type Ethernet frame type (often called EtherType) is used to indicate which protocol isencapsulated in the payload of an Ethernet Frame.

Whena port has flow control enabled, this parameter can be used to limit how long this portcan be Paused or Back Pressured off to prevent a port stall through jamming.The Flow Control on the port is (temporarily) disabled when the Pause refresh framescount exceeds the value of this parameter.Setting this parameter to 0 will allow continuous jamming to be received on thisport.Pause limit out[frame] Limit the number of continuous Pause refresh frames that can be transmitted fromthis port – assuming each Pause refresh is for the maximum pause time of 65536slot times. When full-duplex Flow Control is enabled on this port, this parameter isused to limit the number of Pause refresh frames that can be generated from thisport to keep this port’s link partner from sending any data.Clearing this parameter to 0 will allow continuous Pause frame refreshes to egressthis port as long as this port remains congested.Setting this parameter to 1 will allow 1 Pause frame to egress from this port foreach congestion situation.Setting this parameter to 2 will allow up to 2 Pause frames to egress from thisport for each congestion situation, etc.Ignore Framechecksum Ignore Frame checksum (FCS) - or in other words - Force good FCS in the frame. Whenthis parameter is not set (default behaviour), frames entering this port must have a goodCRC or else they are discarded. When this parameter is set, the last four bytes of framesreceived on this port are overwritten with a good CRC and the frames are accepted bythe switch (assuming that the frame’s length is good and it has a destination).RAy2 Microwave Link – © RACOM s.r.o.98Configuration

Thispriority takes values from 0 to 3, and controls the processing of frames inside the switch.• Untagged frames are provided with 802.1p priority by default.• Priorities may be remapped.• The priority can also be overwritten by the Advanced menu priority derived from a VLAN, SA and/orDA addresses.The Frame priority (FPri) is processed in a similar manner. Frame coming from the network and framebeing sent to the network is marked by this priority.PIRLBetween the port and the common switch there may be between 1 and 5 “flow restrictors” working inparallel according to the schedule “leaky bucket”.

Their passageis regulated thus avoiding network congestion. If there is a framework that does not match the filter ofany Resource, this then passes to the switch without restrictions.Switching blockIn this block (L2-switch) each frame is routed to a designated port according to the Advanced menu.Egress queueBlock output queues. Each port receives frames from the L2 switch through 4 queues (No. 3-0). Thehighest priority has a queue No. 3.

The emptying rate isgoverned by the Rate limit parameter.A Frame sent from the port to the network can be identified by priority FPri, although it is also possibleto change its tag: see menu VLAN - Egress mode.RAy2 Microwave Link – © RACOM s.r.o.100Configuration
Port based ingress rate limiting, see also the Functional diagramFig. 7.25: Menu Switch settings - PIRLThe device supports per port TCP/IP ingress rate limiting along with independent Storm prevention.Port based ingress rate limiting accommodates information rates from 64 Kbps to 1 Mbps in incrementsof 64 Kbps, from 1 Mbps to 100 Mbps in increments of 1 Mbps and from 100 Mbps to 1000 Mbps inincrements of 10 Mbps.In addition to this, the device supports Priority based ingress rate limiting. A given ingress rate resourcecan be configured to track any of the four priority traffic types. One of the popular schemes for imple-menting rate limiting is a leaky bucket. The way a leaky bucket scheme works is that the bucket drainstokens constantly at a rate called Committed Information Rate (CIR) and the bucket gets replenishedwith tokens whenever a frame is allowed to go through the bucket. All calculations for this bucket aredone in tokens. Therefore, both bucket decrementing and incrementing is performed using tokens (i.e.,frame bytes are converted into bucket tokens for calculation purposes).The device supports a color blind leaky bucket scheme.The traffic below Committed Burst Size limit (CBS Limit) is passed without any further actions. If thetraffic burst were to continue and the bucket token depth approaches closer to the Excess Burst Sizelimit (EBS Limit) by less than the CBS Limit, then a set of actions are specified. Note that if the framegets discarded then the equivalent number of tokens for that frame will not get added to the bucket.There are the two default ingress limiting rules already configured in the switch default configuration.They limit the maximum allowed ARP traffic comming to the CPU port to 10Mbps from Eth1 and 10Mbpsfrom Eth2 ports.101© RACOM s.r.o. – RAy2 Microwave LinkConfiguration

BRF is Bucket Rate factor and BI isBucket increment.Burst allocation[b] The Burst allocation (BA) is dependent of the Bucket increment, the CommittedBurst Size limit and the Excess Burst Size limit.The formula for the BA is as follows: BA = 8 * (EBS-CBS) / BI.Where EBS is the Excess Burst Size limit, CBS is the Committed Burst Size limitand BI is the Bucket increment.The Burst allocation size should be less than switch internal memory which is 1Mb.CBS min The minimum value for the CBS limit is related to the maximum frame size andBucket increment.The CBS limit should always be bigger than the CBS min.The calculation for CBS min is as follows:CBS min = BI * MaxFrameSize [bytes].Where BI is the Bucket increment.If the CBS limit is lower than this value (i.e. to allow a large burst), then an ingressstream composed of maximum sized frames may exceed the Committed InformationRate. It is for this reason that we recommend the CBS limit value always staysabove the CBS min value. Also, the CBS limit should never exceed the EBS limit.EBS limit Excess Burst Size limit.The EBS limit should always be bigger than CBS limit.

When this occurs the frame willnot be ingress rate limited.Accountedbytes This parameter determines which frame bytes are to be accounted for in the rateresource's rate limiting calculations.There are for different supported configurations:Frame based configures the rate limiting resource to account forthe number of frames from a given port mapped to this rate re-source.framePreamble (8bytes) + Frame’s DA to CRC + IFG (inter frame gap,12 bytes)layer 1Frame’s DA to CRClayer 2Frame’s DA to CRC - 18 - 4(if the frame is tagged)layer 3A frame is considered tagged if it is either Customer of Provider tagged during in-gress.EBS limit action This parameter controls what kind of action is performed when the EBS limit hasbeen exceeded. Three types of action can be selected:The frame that was received on the port will get discarded.drop105© RACOM s.r.o. – RAy2 Microwave LinkConfiguration
In this mode an Ethernet flow control frame gets generated (if theflow control is enabled for that port) and sent to the source portflow controlbut the incoming frame gets passed through the rate resource. Ifthe port is operating in half-duplex mode then the port gets jammed.The frame that was received on the port is accepted even thoughthere are not enough tokens to accept the entire incoming frame.acceptThis mode is expected to be selected for TCP based applications.It is not recommended for media streaming applications wheredata timing is critical.Flow control mode is expected to be programmed on ports that have a trusted flowcontrol mechanism available. The EBS limit action is a per-port characteristic. If aport has multiple rate resource buckets then all buckets enabled are expected tobe programmed with the same EBS limit action.Sampling mode This mode is used for sampling one out of so many frames/bytes that are beingmonitored. The stream could be identified by the ingress engine as a Policy mirrorand packet sampling can be applied for that streeam using one of the rate resources.In this mode, once the rate resource's "EBS Limit" is exceeded, the next incomingframe from this port that is assigned to this resource gets sent out to the mirrordestination. After sending a sample frame, the token count within the rate resourceis reset to zero and the bucket increments continue for each subsequent framearrival.The sampling mode is useful for limiting the number of Mirror frames sent to themirror destination.Flow controlde-assertion This parameter controls the flow control de-assertion when EBS limit action is setto generate a flow control message. There are two modes available:Flow control gets de-asserted only when the ingress rate resourcehas become empty.emptyFlow control gets de-asserted when the ingress rate resource hasenough room to accept at least one frame of size specified by theCBS limit.For example, if the CBS limit is programmed to be 2k Bytes, thenthe flow control will get de-asserted if there is at least 2k Bytesworth of tokens available in the ingress rate resource.CBS limitBucket type Any given bucket can be programmed to be aggregate rate based or traffic typebased.Rate based ingress rate limit: Limits all types of traffic on the ingress port.Traffic type based ingress rate limit: Limits a specific type of traffic on the ingressport.Mask operation This parameter controls whether an ingress frame must meet both Priority andFrame type requirements to be counted for ingress rate calculations or if meetingonly one requirement is sufficient to be counted for ingress rate calculations forthis rate resource.Priority Any combinations of the four queue priorities can be selected. Frames with markedpriority are accounted for in this ingress rate resource.If there is no priority selected, priority of the frame doesn't have any affect on theingress rate limiting calculations done for this ingress rate resource.RAy2 Microwave Link – © RACOM s.r.o.106Configuration
Frame type Any of the following frame types can be selected to be tracked as part of the rateresource calculations:Management (MGMT), Multicasts, Broadcasts, Unicasts, Address Resolution Pro-tocol (ARP), TCP Data, TCP Ctrl, UDP, Non-TCPUDP (covers IGMP, ICMP, GRE,IGRP and L2TP), IMS, PolicyMirror, PolicyTrap, Unknown Unicasts or UnknownMulticasts.More than one frame type can be selected for a given rate resource.107© RACOM s.r.o. – RAy2 Microwave LinkConfiguration

Port 6.Eth1Eth2CPUAirSchedulingmode Port's Scheduling mode.The device supports strict priority, weighted round robin, or a mixture on a peregress port selection basis.In the strict priority scheme all top priority frames egress for a port until that priority’squeue is empty, then the next lower priority queue’s frames egress, etc. This ap-proach can cause the lower priorities to be starved out preventing them fromtransmitting any frames but also ensures that all high priority frames egress theswitch as soon as possible.In the weighted scheme an 8, 4, 2, 1 weighting is applied to the four priorities unlessan alternate weighting is programmed into the QoS Weights Table. This approachprevents the lower priority frames from being starved out with only a slight delayto the higher priority frames.RAy2 Microwave Link – © RACOM s.r.o.108Configuration
Some applications may require the top priority queue, or the top two priority queuesto be in a fixed priority mode while the lower queues work in the weighted approach.All scheduling modes are selectable on a per port basis.The port scheduling mode can be one of the following values:Use a weighted round robin queuing scheme.weighted RRBUse Strict for priority 3 and use weighted round robin for prior-ities 2,1 and 0strict pri 3Use Strict for priorities 3 and 2 and use weighted round robinfor priorities 1 and 0strict pri 3, 2Use a Strict priority scheme for all prioritiesstrictSpeed guard The speed guard controls automatically the Egress data rate shaping according toavailable capacity of the Air channel. The Air channel capacity check and the Egressshaping adjustment takes place approx. once per 50 ms.Count mode Egress rate limiting count mode. This parameter is used to control which bytes inthe transmitted frames are counted for egress rate limiting as follows:The egress rate limiting is done based on frame count [fps] asopposed to the byte count [kbps] of the packet.framePreamble (8bytes) + Frame’s DA to CRC + IFG (inter frame gap,12 bytes)layer 1Frame’s DA to CRClayer 2Frame’s DA to CRC - 18 - 4(if the frame is tagged)layer 3Only one tag is counted even if the frame contains more than one tag. A frame isconsidered tagged if the egress frame going out onto the wire is tagged.Rate [kbps] /[fps] Egress data rate shaping. When Rate = 0 egress rate limiting is disabled.NOTE: The Count mode parameter is used to control which bytes in the trans-mitted frames are counted for egress rate limiting.If the egress shaping is controlled by frame rate, the desired frame rate can varyfrom 7.6k to 1.488M frames per second. Valid values are between 7600 and1488000.If the egress shaping is controlled by bit rate, the desired rate can vary from 64kbps to 1 Gbps in the following increments:Desired rate between 64 kbps and 1 Mbps in increments of 64 kbpsDesired rate between 1 Mbps to 100 Mbps in increments of 1 MbpsDesired rate between 100 Mbps to 1 Gbps in increments of 10 MbpsTherefore, the valid values are:64, 128, 192, 256, 320, 384,..., 960,1000, 2000, 3000, 4000, ..., 100000,110000, 120000, 130000, ..., 1000000Frame overhead[B] Egress Rate Frame Overhead adjustment.This parameter is used to adjust the number of bytes that need to be added to aframe’s IFG (inter frame gap) on a per frame basis. This is to compensate for aprotocol mismatch between the sending and the receiving stations. For exampleif the receiving station were to add more encapsulations to the frame for the nodes109© RACOM s.r.o. – RAy2 Microwave LinkConfiguration
further down stream, this per frame adjustment would help reduce the congestionin the receiving station.This adjustment, if enabled, is added to the Egress Rate Control’s calculatedtransmitted byte count meaning Egress Rate Control must be enabled for thisFrame Overhead adjustment to work.Weight table The weighted round robin alternate weighting can be defined here. The sequenceof the output queue numbers (0,1, 2 or 3) defines the sequence of the output queueframe egressing.

An indicative description of the function of each block:FrameAn incoming frame contains the destination MAC address DA and the source address SA. The VLAN802.1p priority can be contained in the Ethernet header and the DSCP priority in the IP header. If theframe is a member of a VLAN, it carries it's VID number and 802.1q priority in the tag.VLANA frame is received through ports Eth1, Eth2, Air or from microwave CPU. The head of the frame maychange at this time based on parameters set in the VLAN menu.All untagged frames are assigned a VID. A tagged (VLAN) framework can have its own VID overwrittenby a default VID.The packet priority can be ovewritten according to parameter menus QoS, VLAN and ATU.The FID for searching in the ATU table is allocated to the frame within the VLAN menu (by the inputport) or from the corresponding VID in the VTU table.Member parameter can limit the allowed output direction of ports.Frames sent from a unit transfers through an output port. The Egress mode parameter bound to theport either adds or removes the VLAN tag.VTUValues in the VID determine search results from the VTU table. These are created manually. The SIDindex (enabled ports in terms of STP) FID index (for searching in the address table ATU) taken fromthis search result are assigned to the frame. This FID will overwrite the FID from menu VLAN.Based on this, the VTU can also overwrite the priority of this frame.The permitted output ports and method of working with VLAN tag on the output are also defined here.STUThe Spanning tree protocol in this table maintains the status of ports from the viewpoint of the authorizednetwork throughput and the learning of routing. Protocol MSTP is used.Each VTU entry uses some of the entries in the STU. Entries in the ATU are created in accordancewith these assigned states.The port state behaviour is determined by the STP.ATU settingsAny assigned parameters dictate how the ATU table should be used.The Global section of this menu provides for passage of MGMT frames (e.g. BPDU).In the Port settings section, the behaviour of individual port is defined:115© RACOM s.r.o. – RAy2 Microwave LinkConfiguration
- Behaviour of the ATU table in terms of automatically creating records (Learning, Hold at 1, ATU refresh,Learn limit).- Discarding frames according to the source addresses.- Handling frames with unfamiliar destination addresses.- The frames' priority can be overridden by the SA or the DA.ATUThe ATU table determines the output port on the RAy according to the DA in the frame.Records are arranged according to the FID and the MAC addresses.The table is created and maintained based on informations contained in incoming frames (learning).Manual recording is also possible.The record can be dynamic or static.Priority frames with a static record can be overridden by the SA or DA.The results of searching the ATU provide the set of output ports or trunk number.RSTPThe RSTP demon turns off redundant paths through the network (switch ports), or re-activates themin the case of failure in other branch.The Global section of this menu contains switch priority for the RSTP and necessary time constants.The Port settings section holds the value of each port as seen by the RSTP. This information indicatesif the RSTP shuts down or restarts a redundant port if a route is interrupted.TrunkThe Trunk enables the distribution of data load on multiple ports. The ratio of distribution is determinedby parameter Balancing mode.RAy2 Microwave Link – © RACOM s.r.o.116Configuration

Priority only tagged frames (with a VIDof 0x000) are considered untagged. This feature works whether 802.1q is enabled onthe port or not.If the port is configured in Provide Mode and this parameter is enabled, frames thatcontain an Ether Type that matches the port's PortEType (Ether type parameter) thathave a non-zero VID will be discarded.Discarduntagged When this parameter is enabled all non-MGMT frames that are processed as untagged,are discarded as they enter this switch port. Priority only tagged frames (with a VIDof 0x000) are considered untagged. This feature works whether 802.1q is enabled onthe port or not.If the port is configured in Provide Mode and this parameter is enabled, frames thatdon't contain an Ether Type that matches the port's PortEType (Ether type parameter)that have a non-zero VID will be discarded.VTU priorityoverride When this parameter is set to anything other than none, VTU priority overrides canoccur on this port. A VTU priority override occurs when the determined VID of a frameresults in a VID whose Use VID priority parameter is enabled. When this occurs three(other than none) forms of priority overrides are possible:Normal frame priority processing occurs.noneThe VID priority value assigned to the frame's VID (in the VLANdatabase) is used to overwrite the frame's previously determinedframeFPri (frame priority). If the frame egresses tagged the priority in theframe will be this new VID priority value - the frame is permanentlymodified.RAy2 Microwave Link – © RACOM s.r.o.120Configuration
The VID priority value assigned to the frame's VID (in the VLANdatabase) is used to overwrite the frame's previously determinedqueueQPri (queue priority). The QPri is used internally to map the frameto one of the egress queues inside the switch. QPri override will notaffect the contents of the frame in any way.Both the above overrides take place on the frame.frame+queueThe VTU Priority override has higher priority than the port's Default Priority and theframe's IEEE and/or IP priorities. The priority determined by the frames' VID canhowever be overridden by the frames' SA and/or DA Priority Overrides.Force defaultVID Force to use Default VID. When 802.1q is enabled on this port and this parameter isenabled, all Ingress frames' VID are ignored and the Default VID is assigned and re-placed into the frame (if the frame egresses tagged). When this parameter is disabledall IEEE802.3ac Tagged frames with a non-zero VID use the frames' VID unmodified.When 802.1q is disabled on this port, this bit has no effect.Default VID Default VLAN Identifier. When 802.1q is enabled on this port the Default VID parameteris used as the IEEE Tagged VID added to untagged or priority tagged frames duringegress that ingressed from this port. It is also used as a tagged frame's VID if theframe's VID was 0x000 (i.e., it is a priority tagged frame) or if the port's Force DevaultVID is enabled.When 802.1q is disabled on this port, the Default VID field is assigned to all framesentering the port (whether tagged or untagged). This assignment is used internal tothe switch.FID Port's Default Filtering Information Database (FID). This parameter can be used withnon-overlapping VLANs to keep each VLAN's MAC address mapping database sep-arate from the other VLANs. This allows the same MAC address to appear multipletimes in the address database (at most one time per VLAN) with a different portmapping per entry. This field is overriden by the FID returned from a VTU hit and itshould be zero if not used. It must be a unique number for each independent, non-overlapping, address database if used.IGMPsnooping IGMP and MLD Snooping. When this parameter is enabled and this port receives anIPv4 IGMP frame or an IPv6 MLD frame, the frame is switched to the CPU port over-riding the destination ports determined by the DA mapping. When this parameter isdisabled IGMP/MLD frames are not treated specially.IGMP/MLD Snooping is intended to be used on Normal Network or Provider portsonly.ARPmirroring When this parameter is enabled non-filtered Tagged or Untagged Frames that ingressthis port that have the Broadcast Destination Address with an Ethertype of 0x0806are mirrored to the CPUDest port. This mirroring takes place after the ingress mappingdecisions to allow ARPs to get to a CPU that is otherwise isolated. When this bit iscleared to a zero no special ARP handling will occur.VLAN tunnel When this parameter is disabled, the port based VLANs defined in the VLAN Table,802.1q VLANs defined in the VTU and Trunk Masking are enforced fo ALL frames.When this parameter is enabled, the port based VLAN Table masking, 802.1q VLANmembership masking and the Trunk Masking are bypassed for any frame enteringthis port with a DA that is currently 'static' in the ATU. This applies to unicast as wellas multicast frames.121© RACOM s.r.o. – RAy2 Microwave LinkConfiguration
While enabled, the Unicast frames with the management CPU DA can go from theEth1 and Eth2 ports in to the CPU port. The static record with the CPU DA in the ATUtable has to be configured (it is pre-configured by default).Member(VLAN Table) The In Chip Port based VLAN Table contains parameters used to restrict the outputports to which an input port can send frames. These parameters (VLANTable bits)are used for all frames, except for MGMT frames, even if 802.1q is enabled on thisport. These parameters restrict where a port can send frames to (unless a VLANTunnelframe is being received). If ForceMap (Learning) is enabled, these parameters indicatewhich port or ports all frames that ingress this port are sent to overriding the mappingfrom the address database.The default setting prevents sending frames from Eth1 to Eth2 and vice versa. Thisis very important for separating different networks (e.g. different customers) connectedto separate user ports.The Link authorization guard affects the user data flow through the Air channel. Whenthe Link authorization guard is enabled, the user Ethernet ports to Air port connectioncontrol is disabled. Parameter status of user Ethernet to Air port connection changesdynamically according to Link authorization status.RAy2 Microwave Link – © RACOM s.r.o.122Configuration

Port 6.Eth1Eth2CPUAirLearning(ForceMap) When this parameter is disabled, normal frame processing occurs.When this parameter is enabled, all received frames will be considered MGMT (MG-MT=Management frames, frames that can tunnel through Blocked ports) and aremapped to the port or ports defined in the VLANTable bits overriding the mappingfrom the address database. The forcing function is needed to get BPDU frames toegress specific ports by the CPU for the Spanning Tree Protocol. ForceMapped frameswill egress ports that are not in the Disabled port state (i.e., they are MGMT framesand will egress via Blocked ports). This parameter is accessible by the CPU's IngressHeader so the CPU can enable and disable MGMT and forcing on a frame by framebases.NOTE: Learning is disabled on MGMT frames, so enabling this parameter alsodisables learning on frames entering this port.Hold at 1 Hold Aging ATU Entries at an Entry State value of 1. When this parameter is disabled,a zero normal Aging occurs for ATU entries associated with this port. When thisparameter is enabled ATU entries associated with this port will age down to an Entrystate of 1 but will not go to 0. This feature can be used (for example) to keep dynamicrecords in the ATU table.ATU refresh Normal address learning is enabledunlockedAuto refreshing of known addresses will occur even if this port isLocked. Already known addresses will be auto refreshed (i.e., theirknownEntry State will be updated to 0x7 whenever this address is used asa source address in a frame on this port) even when this port isLocked.CPU directed learning (needed for 802.1X MAC authentication) isenabled. Automatic SA learning and refreshing is disabled in thismode.lockedDA mapping When this parameter is enabled, normal switch operation occurs where a frame's DAis used to direct the frame out of the correct port. When this parameter is disabled theframe will be sent out of the port defined by EgressFloods even if the DA is found inthe address database. The static ATU table records are used, even in DA mappingdisabled status.129© RACOM s.r.o. – RAy2 Microwave LinkConfiguration
Egress block Egress Flooding mode. The DA of every unicast and multicast frame is searched inthe ATU. If the DA is found in the address database it is considered known. If it is notfound it is considered unknown. Frames with known DA's are not affected by this re-gister.Frames with unknown DA's generally flood out all the ports (except the port they ori-ginally came in on). This register can be used to prevent frames with unknown DA'sfrom egressing this port as follows:Do not egress any frame with an unknown DA (unicast or multicast)unknownDo not egress any frame with an unknown multicast DAunknownmulticastDo not egress any frame with an unknown unicast DAunknownunicastEgress all frames with an unknown DA (unicast and multicast)noneSA filtering Source Address Filtering method:No frame will be filtered (i.e. discarded) as a result of the contentsof its Source Address field.disabledIngressing frames will be discarded if their SA field is not in the ATU'saddress database (i.e. it's a new or unknown Source Address) or ifdropon lock this port's bit is not set in the PortVec bits for the frames' SA (i.e. thisport is not the source port for that MAC address).

Otherwise, the frameswill be discarded if their SA field is not in the ATU's address database(i.e. it's a new or unknown Source Address) or if this port's bit is notset in the PortVec bits for the frames' SA (i.e. this port is not thesource port for that MAC address). This mode is a form of MAC based802.1X where some frames can be forced to the CPU for furtherauthentication prior to full authorization.Learn limit(LearnLimit) When this parameter is set to zero, normal address learning and frame policy occurs.When this parameter is non-zero the number of MAC addresses that can be learnedon this port are limited to the value of this parameter. Automatic learning and framepolicy will occur normally until the number of unicast MAC addresses auto-learnedfrom this port reaches the port's LearnLimit (addresses that were learned from thisport but were aged out are not counted - i.e., this register limits the number of 'active'unicast MAC addresses associated to this port). When the LearnLimit has been reachedany frame that ingresses this port with a source MAC address not already in the ad-dress database that is associated with this port will be discarded (the port will act asif the port is Locked and the port's DropOnLock SAFiltering mode is set). Normal auto-learning will resume on the port as soon as the number of 'active' unicast MAC ad-dresses associated to this port is less than the LearnLimit (due to address aging).Care is needed when enabling this feature:Enable "Learn to all" (GL1-0x0A:11:3 Learn2All=1)RAy2 Microwave Link – © RACOM s.r.o.130Configuration

An SA ATU priority override occurs when the source address of a frameresults in an ATU hit where the SA's MAC address returns an EntryState that indicatesPriority Override. When this happens three forms of priority overrides are possible(other than none):Normal frame priority processing is active.nonePRI value assigned to the frame's SA (the MAC priority field in theATU database) is used to overwrite the frame's previously determinedframeframe priority (FPri). If the frame egresses, the tagged priority in theframe will be this new PRI value.The two upper bits of the PRI value assigned to the frame's SA (theMAC priority field in the ATU database) are used to overwrite thequeueframe's previously determined queue priority (QPri). The QPri is usedinternally to map the frame to one of the egress queues inside theswitch. QPri override will not affect the contents of the frame in anyway.Both above overrides take effect on the frameframe+queueThe SA ATU Priority Override has a higher priority than the port's Default Priority, theframe's IEEE and/or IP priorities and the VTU Priority Override.

Portassociation(PAV)Port Association Vector for ATU learning. The value in these bits (one bit per port) isused as the port's DPV on automatic ATU Learning or Entry_State refresh wheneverthese bits contain a non-zero value. When these bits are all zero, automatic Learningand Entry_State refresh is disabled on this port.For normal switch operation, this port's bit should be the only bit set in the vector.These bits must only be changed when frames are not entering the port.The PAV bits can be used to set up port trunking (along with the VLANTable bits). Forthe two ports that form a trunk, set both of their port's bits in both port's PAV registers(this Port association parameter for both ports of the trunk), then use the VLANTableto isolate the two ports from each other, or to use the Trunk Mask table to steer thetraffic from the other ports down the desired trunk line of the pair using DA/SA LoadBalancing.RAy2 Microwave Link – © RACOM s.r.o.132Configuration

RSTPFig. 7.41: Menu Switch settings - Advanced - RSTPThe Rapid Spanning Tree Protocol (RSTP) is a network protocol that ensures a loop-free topology forany bridged Ethernet local area network. The basic function of RSTP is to prevent bridge loops andthe broadcast radiation that results from them. Spanning Tree Protocol also allows network design toinclude spare (redundant) links to provide automatic backup paths if an active link fails, without thedanger of bridge loops, or the need for manual enabling/disabling of these backup links.RSTP enable When RSTP is enabled, the bridge is created and RSTP service is initiated. Shouldthe RAy2 unit be connected via two Etherent cables (using Eth1 and Eth2 ports), theactive participation of the RSTP protocol may be necessary. If the parameter is notenabled, the RAy2 unit transfers the BPDU frames transparently.NOTE: To enable proper RSTP functionality, these switch parameters has to be set:Switch settings / Interface / Port advanced / Frame mode / p5 CPU: "ether typeDSA"Switch settings / Interface / Port advanced / Ether type / p5 CPU: "0xDADA"Switch settings / Advanced / ATU settings / Reserved multicast to CPU: "Enable"Bridgepriority The priority value is a number between 0 and 61440 in incremental steps of 4096,with a default value of 32768. Lower priority values are 'better'. The bridge with thelowest priority value will be elected 'root bridge'.Hello time [s] The hello time is the time between each Bridge Protocol Data Unit (BPDU) that is senton a port. Hello time is equal to 2 seconds by default.RAy2 Microwave Link – © RACOM s.r.o.138Configuration
Max age [s] The max age timer controls the maximum length of time that passes before a bridgeport saves its configuration BPDU information. This time is set to 20 sec by default.Forwarddelay [s] The forward delay is the time that is spent in the listening and learning state. This timeis equal to 15 sec by default.Algorithm This parameter sets the bridge's spanning tree algorithm to operate in normal (RSTP)or force it to operate in slow (STP) mode. In normal mode, RSTP reverts back to STPon ports where it sees other hosts operating in STP mode.Port name Identification of the internal switch port.

TrunkFig. 7.42: Menu Switch settings - Advanced - TrunkPort trunking is supported by the device using any combinations of ports. The ports that are to be as-sociated with the trunk need to have all the port members' defined with the same Trunk Id and theEnabled parameter has to be enabled.When a frame enters a Trunk Port its Source Address (SA) is learned with its association to the ingressport's TrunkID number. In this way the contents of the address database contain the same associationwith the frame's SA regardless of the link of the trunk the frame entered the switch.When frames are routed back toward a trunk the frame will have its Destination Address (DA) foundfrom the address database. If the frame's DA is unknown the frame will try to flood out all ports of thetrunk (this is OK in so far as this will be fixed with load balancing). If the frame's DA is found, the entrywill indicate mapping to a trunk and the entry's DPV bits will contain the TrunkID associated with thisframe's DA. This TrunkID needs to be converted into a DPV (Destination Port Vector) that the rest ofthe switch can use. This is accomplished by accessing the Trunk Mapping table using the TrunkID thatwas in the ATU's entry.Balancingmode Hash DA and SA for TrunkMask selection. Trunk load balancing is accomplished usingthe frame's DA and SA fields to access one of eight Trunk Masks.

Remote unit authorizationThe RAy2 unit in default configuration, establishes a connection with any remote unit and both unitsact as a communication pair. Should the higher protection from the unauthorized communication take-over be required, it is possible to use the so called Secured mode of remote unit authorization. Thismode is based on locking the two specific units into one communication pair. Units with Secured modeRAy2 Microwave Link – © RACOM s.r.o.168Command Line Interface
activated refuse to make a connection with any other communication unit. The units are locked usingthe unique authorization keys. The keys are exchanged between the units concerned. The authorizationkeys can be backed up to an external medium to be able to make a service unit exchange, if necessary.Should The Link authorization quard be disabled, the user data occurs even it the remote unit is notauthorized.The Secured mode set up process consists of a few steps:• Unique authorization keys generation:cli_link_key_gen -t b• Authorization keys exchange between the two communication units:cli_link_key_swap• Authorization keys activation:cli_link_key_apply -t bParameter -t determines whether we configure the whole link (-t b) or only one unit (-t l).• Secured mode activation. Both sides of the link must have identically secured mode set On or Off:cli_cnf_set -t b SVC_SECURE_PEER_MODE=on PEER_SVC_SECURE_PEER_MODE=on• Secured mode de-activation:cli_cnf_set -t b SVC_SECURE_PEER_MODE=off PEER_SVC_SECURE_PEER_MODE=off• Backup of the keys to an external medium. The backup has to be performed to be able to makeservice exchange of the corrupted unit, if necessary. The new exchanged unit is not able to makean active connection with the other unit if it is not loaded with the proper authorization key.cli_link_key_save -s s -f <file>The key is backed up to a selected file in the internal unit file system. It can be transferred to anexternal medium using for example the scp client.• Authorization key restoration from the external medium.The key has to be transferred to the unit internal file system first.

9. Troubleshooting•Polarization incorrectInstall the unit with the correct horizontal or vertical polarization: The arrow mark (placed just nextto the Status LED) indicates the unit RX polarization. When the arrow is perpendicular to the earth,the unit receives a signal in vertical polarization. When the arrow is parallel to the earth, the unitreceives a signal in horizontal polarization. The connectors must point downward at an angle.•The link cannot be establishedStart with the most “resilient” configuration. This configuration depends on the type of unit. We re-commend using the narrowest available bandwidth (e.g. 3.5 MHz), the lowest modulation level(QPSK) and maximum available output power. TX and RX channels must be the same as the RXand TX channels in the remote unit. When the connection has been established and the antennashave been directed, proceed with operation parameters.Units operating in licensed bands (RAy2-10, RAy2-11) are mounted with the same RX polarization(the polarization indication arrows show the same polarization on both units).Units working in the bands equipped with RAy2-17 and RAy2-24 units must be mounted with oppositepolarization; one with RX horizontal polarization (horizontal arrow) and the second with RX verticalpolarization (vertical arrow).•Access to the Local unit is blockedAccess to the Local unit may be accidentally blocked, for instance by disabling HTTPS access. Ifyou can access the Remote unit over HTTPS, type its address in your web browser's address field.The link will transfer the packet over the Local unit with blocked service access all the way to theRemote unit, which will give you access to the control menus of both units. Warning, the Remoteunit will report as Local.•Distinguishing Local-RemoteA unit accessed via service access always reports as Local. If you connect through another (peer)unit and radio channel, a certain amount of caution is necessary. For example, do not reduce thetransmission power so that the link interrupts accidentally. Errors of this type should be fixed by therollback function within approx. 1 minute.Resolution can be done by comparing the length of ping on Local and Remote. Pinging the unitbehind the radio channel is slower. The difference is more pronounced in the case of a long packetand the low speed of the radio channel.•Access securityFor better protection against unauthorised access to configuration you should only allow as fewkinds of access as possible. The most secure type is SSH with key – leave only SSH active with"only key" choice.•RSSTo configure the link and monitor its state, several menus display the RSS signal strength. Pleasekeep in mind, that Ray2 is not a measuring instrument, hence the precision of the RSS reading isRAy2 Microwave Link – © RACOM s.r.o.170Troubleshooting
limited. Though, in most situations the RSS reading accuracy is better than ± 2dB, the absoluteRSS value should not be used for accurate comparisons e.g. between two links.•Problem with https certificateSee the Appendix G, Https certificate•Overexcited receiverA natural property of each radio receiver is to compress the signal in one of the functional blocks,typically in a second receiving mixer. A downside of this property is the distortion of the input signal(decrease in the signal to noise ratio, i.e. the distortion measured as SNR).In extreme cases, this can lead to the disintegration of the radio link due to reduced signal to noiseratio (distortion). Extreme limits for guaranteed availability of the RAy2 connections are:○ -30 dB for all channel bandwidths and fixed modulation 256QAM○ -10 dB for all channel bandwidths and fixed modulation QPSK171© RACOM s.r.o. – RAy2 Microwave LinkTroubleshooting
