User need to configure the DNS server IP address manually. PPPoE Active Mode, Max Idle Time and Redial Period can be configured. When “Connect on Demand” is selected, PPPoE will establish the connection with the remote access concentrator only when hosts in the local subnet need to access the internet. If the parameter is set “Keep Alive”, PPPoE will establish the connection with the remote access concentrator upon boot-up. Default setting of Max Idle Time is 30 minutes. Only when PPPoE works under Connect on Demand mode, it will be disconnected if PPPoE connection has been idle for the Max Idle Time. When last attempt failed, C1n CPE/AP will attempt to establish the PPPoE connection at Redial Period.
C1n_Configuration_Manual_-_fm_1.0.0.x_for_US_&_Canada_20130116.doc Commercially Confidential 23 4.9.2 LAN Configuration In Gateway Mode, the C1n can be a DHCP server, a DHCP relay or none of them. When the DHCP Server Mode sets to Server, the C1n will act as a DHCP server and use the settings specified in the field Start IP Address, Maximum Number of DHCP Users and DNS to serve the wireless clients. 1. Configure the Local IP Address and Subnet Mask Length. Local IP Address is the gateway IP address for the client who associates C1n CPE/AP. Only the clients under the same subnet of local IP address can get IP address from C1n Super WiFi CPE/AP. 2. Configure the Start IP Address, Maximum Number of DHCP Users, and DNS, see Figure 16. 3. Reboot the C1n Figure 16 Configure DHCP Server
C1n_Configuration_Manual_-_fm_1.0.0.x_for_US_&_Canada_20130116.doc Commercially Confidential 24 When the DHCP Server Mode sets to Relay, the C1n will redirect all DHCP requests from the wireless clients to a backend DHCP server with IP address specified by the Relay Server IP Address. 1. Configure the Relay Server IP Address, see Figure 17. 2. Reboot the C1n Figure 17 Configure DHCP Relay Server When the DHCP Server Mode sets to Disabled, the C1n will neither be a DHCP server nor a DHCP Relay and hence the wireless clients CANNOT get IP addresses from the C1n CPE/AP to access the Internet. Instead, each wireless client should set a fixed static IP address which is in the same network domain as the C1n.
C1n_Configuration_Manual_-_fm_1.0.0.x_for_US_&_Canada_20130116.doc Commercially Confidential 25 4.9.3 Port Forwarding Configuration In Gateway mode, the user can configure the Port Forwarding. Port Forwarding is the technique to forward a private port to public port. The external user can reach a port on a private IP address from the outside via C1n. This allows the remote computers to connect a specific computer with a private LAN. 1. Configure the Private IP, Private Port, Type and Public Port, see Figure 18. 2. Choose Enable 3. Reboot the C1n Figure 18 Configure Port Forwarding 4.9.4 DMZ Configuration Demilitarized Zone is a physical or logical sub network that contains and exposes services to external network. By enable DMZ zone, external user can only access client with IP configured in DMZ IP. DMZ feature could be configured only under gateway mode and DMZ IP should be under LAN IP subnet.

If the AP loses its backhaul connectivity, it forces the clients to re-associate with another AP by changing its SSID to a default “C1n Safe Mode XXX”, where “XXX” is the MAC address of the 2.4GHz radio in hexadecimal. This action can protect the client from connecting to a AP which has no backhaul to the Internet end. Default Access Link Safe Mode is Disabled. Press the icon Enabled, C1n CPE will work under Access Link Safe Mode. In the case where multiple physical backhauls are available, the Backhaul Link Self-Healing feature will switch to other backhaul if the current one goes down. For example, when default backhaul is set to 5GHz Radio, once the 5GHz Bridge link is broken down, C1n Super WiFi CPE/AP will try Ethernet end as its new backhaul. Default setting is Disabled. After enabled the Backhaul Link Self-Healing, Default Backhaul Link can be configured. Three different Ping Host can be added to the list for monitoring the connectivity. If either Access Link Safe Mode or Backhaul Link Self-Healing is enabled, the AP will ping those specified hosts periodically at the Ping Interval configured.

Under AP mode, the Auto Channel Selection is disabled by default; the C1n is fixed on Channel 6. When Enabled of Auto Channel Selection is chosen, C1n Super WiFi CPE/AP can scan all available radio channels which are assigned to the regulatory domain. The “cleanest” channel is then selected as the operating channel. NOTE: After changing frequency channel, it takes around 3 minutes for C1n to optimize its 2.4GHz radio performance.
C1n_Configuration_Manual_-_fm_1.0.0.x_for_US_&_Canada_20130116.doc Commercially Confidential 28 4.11.1 Service Set IDentifier (SSID) and Virtual Access Point (VAP) In order for the C1n CPE/AP and mobile clients to communicate, they must all be configured to use the same SSID for communication both at the VAP and clients ends. SSID broadcast can be enabled or disabled by selecting Suppress SSID. Suppress SSID is used to prevent unauthorized users scanning for SSID while still allowing users who know the correct SSID to connect. NOTE: Suppress SSID can be enabled only when C1n works under AP mode. 4.11.2 Wireless Mode and Radio Frequency Altai C1n Super WiFi CPE/AP can offer 2.4GHz radio access, the following tables list the operation mode and available frequency under the particularly wireless mode. Default setting of AP mode radio is working on 2.4GHz 300Mbps (802.11ng HT40) and default channel is channel 3 (2422MHz). 2.4GHz Radio Mode Data Rate Channels Radio Frequency 802.11b 11Mbps 1,2,3,4,5,6,7,8,9,10,11 2412MHz-2462MHz 802.11b/g 54Mbps 1,2,3,4,5,6,7,8,9,10,11 2412MHz-2462MHz 802.11ng HT20 130Mbps 1,2,3,4,5,6,7,8,9,10,11 2412MHz-2462MHz 802.11ng HT40 300Mbps 3,4,5,6,7,8,9 2422MHz-2452MHz Table 2 2.4GHz Radio Frequency 4.11.3 Transmit Power The value of the Transmit Power depends on both the gain of the 2.4GHz antenna and the maximum value of the Effective Isotropic Radiated Power (Max EIRP) allowed by the country in which C1n is used. The Transmit Power should be configured within the given range as shown in Figure 20 NOTE: Click the Update icon to store the changed settings. 4.11.4 Channel Bandwidth There are two kinds of Channel Bandwidth, 20MHz and 10MHz. 4.11.5 Bridge Distance This feature is used to specify the Bridge distance value in kilometers using slider or enter the value manually. The value could be modified between 0 and 5.Changing the distance value will change the ACK Timeout to the appropriate value of the distance in order to make C1n getting best performance at that distance. 4.11.6 LED signal There are 6 LEDs at the back of C1n, the 4 LEDs in the right side are used for signal strength indication in CPE mode or AP mode. These 4 LEDs altogether can display 8 levels of signal strength in the following manner.

The 8 displayed signal levels are classified as: Table 4 LED signal level 4.11.7 Advanced Radio Setting More radio parameters can be verified and altered by selecting the Advanced icon in the field of Advanced Setting. The parameters are shown in Figure 21. Data Rate: Default setting is "best". When the "best" data rate is chosen, the C1n AP attempts to deliver unicast data frames at the highest possible "optimal" data rate that allows for reliable data transmission. If there are obstacles or interferences, the AP automatically steps down to a lower optimal data rate. Furthermore, the optimal data rate is adjusted periodically by the AP, based on past performance of the data transmissions at different data rates. Fragment Threshold: It means the size of each frame. If it is set to 256 bytes and the size of data block is 1024 bytes, the data block will be divided to four frames to send. RTS/CTS Threshold: RTS is a flow control mechanism to prevent collision between 802.11b and 802.11g mobile stations to send data to the access point in the same time. CTS is another flow control mechanism to prevent collision when two mobile stations, who do not know the existence of each other, send data to the access point in the same time. RTS and CTS are used for point-to-multipoint bridge application and they are enabled when the threshold set to 2346.

The C1n AP transmits beacons for each supported BSS, with each BSS using the same beacon interval. The beacon interval is a value between 25 and 1000 ms. The following table showed is the best suggested interval worked with the current operated APs. Note that it is not suggested to change the parameters in Advanced Radio Settings unless you are experienced administrators. Number of active VAPs Auto Beacon Interval (ms) 1 100 2 200 3 300 4 400 Table 5 Beacon Interval Table DTIM: Default setting is 1. The DTIM interval, also known as the data beacon rate, denotes the frequency at which AP beacon will include a DTIM. This frequency is measured in the number of beacon intervals, and is a value between 1 and 255. Multicast Rate: This option allows Multicast packets to be sent in higher rates (up to the 54 Mbps) than commonly used (1 Mbps at IEEE 802.11b mode, 6 Mbps at IEEE 802.11g/a mode). This is ALTAI's C1n proprietary feature thus it may be incompatible with the devices from other vendors. Both C1n based devices the sender (Station) and the receiver (Access Point) must have the same Multicast Rate configured in order to achieve better multicast packet throughput performance Short Preamble: Default setting is "Enabled". Short preamble usage is only available for 802.11b. If this option is set to "Enabled", both short and long preamble are used. Only long preambles are used when Short Preamble is set to ‘Disabled’. Protection Mode: Default setting is "None". C1n turns off CTS protection under protection mode disabled. C1n will turns on CTS protection when Protection Mode is set to ‘always’. If Protection Mode is set to "Auto", the C1n dynamically turns on and off CTS protection depending on whether there are any 802.11b STAs associated/any traffic from associated 802.11b STAs. Short Slot Time: Default setting is "disable". In 802.11g mode, if this feature is enabled, the C1n advertises and uses 9 us slot times until the first client associates that cannot support 9 us. Then, C1n advertises and uses 20 us slot times until all the stations that cannot support 9 us have timed out. If it is disabled, the C1n only uses long slot times. In 802.11b mode only long slot times are used. QoS: Default setting is "Enabled". If QoS Mode is set to "Disabled", all traffic has equal priority and equal chance of being delivered in a timely manner. When congestion occurs, all traffic has an equal chance of being dropped. If QoS Mode is set to "Enabled", the QoS implementation is based on WMM, which is a subset of the 802.11e draft. It prioritizes traffic between the AP/Bridge and wireless client device/peer bridge device, on a per VAP basis. This control enables QoS for 2.4GHz radios.

AP Signal The “Lock to AP Mac” function is used to allow the CPE to maintain connection to a particular AP with a specific MAC under Station mode. With AP lock on, the CPE will lock to the defined MAC address and no roam between several Access Points with the same SSID. The MAC address will be automatically filled in when user chooses the preferred SSID from scanning list. Min AP signal can be configured under station mode VAP. C1n measure the signal strength of remote SSID. Station mode VAP can only associate to remote SSID with higher signal strength than min AP signal threshold. Default Min.ap signal Strength value is "-94". The value can be set from -94 to -10. The MAC address of the preferred AP can be inputted, if the AP is found and the signal strength is higher than the min.ap signal strength, the C1n will connect to the AP. If the C1n received signal is lower than the min.ap signal strength and does not have the Lock MAC address set, it will connect to another AP with same broadcast SSID. 4.11.12 AP Mode By clicking AP, user can switch C1n from Station mode to AP mode.

IEEE 802.1Q is also the name of the standard issued by this process, and in common usage the name of the encapsulation protocol used to implement this mechanism over Ethernet networks. This protocol allows for individual VLANs to communicate with one another with the use of a layer-3 (network) router. 802.11 802.11 refers to a family of specifications developed by the IEEE for wireless LAN technology. 802.11 specifies an over-the-air interface between a wireless client and a base station or between two wireless clients. The IEEE accepted the specification in 1997. 802.11a An extension to 802.11 that applies to wireless LANs and provides up to 54 Mbps in the 5GHz band. 802.11a uses an Orthogonal Frequency Division Multiplexing (OFDM) encoding scheme rather than Frequency Hopping Spread Spectrum (FHSS) or Direct Sequence Spread Spectrum. 802.11b Also referred to as 802.11 High Rate or Wi-Fi. It is an extension to 802.11 that applies to wireless LANS and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz band. 802.11b uses only DSSS. 802.11b was a 1999 ratification to the original 802.11 standard, allowing wireless functionality comparable to Ethernet. 802.11e A supplement to the IEEE 802.11 wireless LAN (WLAN) specification for enhancements to the 802.11 Medium Access Control (MAC) to improve and manage Quality of Service (QoS), provide Classes of Service (CoS), and enhanced security and authentication mechanisms. 802.11g The 802.11g specification is a standard for Wireless Local Area Networks (WLANs) that offers transmission over relatively short distances at up to 54 megabits per second (Mbps), compared with the 11 Mbps theoretical maximum with the earlier 802.11b standard. Networks employing 802.11g operate at radio frequencies between 2.400 GHz and 2.4835 GHz, the same band as 802.11b. But the 802.11g specification employs Orthogonal Frequency Division Multiplexing (OFDM), the modulation scheme used in 802.11a, to obtain higher data speed. Computers or terminals set up for 802.11g can fall back to speeds of 11 Mbps. This feature makes 802.11b and 802.11g devices compatible within a single network. Modification of an 802.11b access point to 802.11g compliance usually involves only a firmware upgrade. 802.11i A supplement to the IEEE 802.11 wireless LAN (WLAN) specification for enhanced security through the use of stronger encryption protocols such as the Temporal Key Integrity Protocol (TKIP) and AES Counter-Mode Cipher Block Chaining Message Authentication Code Protocol (AES-CCMP). These protocols provide replay protection, cryptographically keyed integrity checks, and key derivation based on the IEEE 802.1X port authentication standard. ACL Access Control List: It is a table that tells a computer operating system which access rights each user has to a particular system object, such as a file directory or individual file. ad-hoc mode An 802.11 networking framework in which devices or stations communicate directly with each other, without the use of an Access Point (AP). Ad-hoc mode is also referred to as peer-to-peer mode or an Independent Basic Service Set (IBSS). Ad-hoc mode is useful for establishing a network where wireless infrastructure does not exist or where services are not required.

More commonly, it refers to the rated throughput capacity of a network protocol or medium. The frequency range necessary to convey a signal measured in units of hertz (Hz). broadcast A data frame or packet that is transmitted to every node on the local network segment (as defined by the broadcast domain). Broadcasts are known by their broadcast address, which is a destination network and host address with all the bits turned on. channel Communication path wide enough to permit a single RF transmission. Multiple channels can be multiplexed over a single cable in certain environments. dB decibels: Unit for measuring relative power ratios in terms of gain or loss. Units are expressed in terms of the logarithm to base 10 of a ratio and typically are expressed in watts. dB is not an absolute value, rather it is the measure of power lost or gained between two devices. Because antennas and other RF devices/systems commonly have power gains or losses on the orders of magnitude or even orders of four orders of magnitude, dB is a more easily used expression. dBd decibels over Dipole: A relative gain measurement with respect to a half wave dipole (0 dBd = 2.14 dBi) using a standard dipole antenna as a reference. dBi dBi referenced to an isotropic antenna, which theoretically is perfect in terms of symmetric patterns of radiation. Real world antennas do not perform with even nominal amounts of symmetry, but this effect generally is used to the advantage of the system designer. dBm decibels per Milliwatt: 0 dBm is defined as 1 mw at 1 kHz of frequency at 600 ohms of impedance. DHCP Dynamic Host Configuration Protocol: Provides a mechanism for allocating IP addresses dynamically so that addresses can be reused when hosts no longer need them. DNS Domain Name Server: System used on the Internet for translating names of network nodes into addresses. DSSS Direct Sequence Spread Spectrum: One of two types of spread spectrum radio technology used in wireless LAN (WLAN) transmissions. To increase a data signal's resistance to interference, the signal at the sending station is combined with a higher-rate bit sequence that spreads the user data in frequency by a factor equal to the spreading ratio.
C1n_Configuration_Manual_-_fm_1.0.0.x_for_US_&_Canada_20130116.doc Commercially Confidential 54 EIRP Effective Isotropic Radiated Power: Term for the expression of the performance of an antenna in a given direction relative to the performance of a theoretical (isotropic) antenna and is expressed in watts or dBW. EIRP is the sum of the power sent to the antenna plus antenna gain. encryption The conversion of information into a scrambled form that effectively disguises it to prevent unauthorized access. Every encryption scheme uses some well-defined algorithm, which is reversed at the receiving end by an opposite algorithm in a process known as decryption. Ethernet Baseband LAN specification invented by Xerox Corporation and developed jointly by Xerox, Intel, and Digital Equipment Corporation. Ethernet networks use CSMA/CD and run over a variety of cable types at 10 Mbps. Ethernet is similar to the IEEE 802.3 series of standards. FastRoamingTM The Trapeze Mobility System feature that quickly hands off a roaming user's credentials. Mobility Exchanges in a Trapeze Mobility Domain pass each other this vital user information to permit seamless roaming. This allows 802.1X and non-802.1X, MAC-authenticated devices, such as 802.11 phones, to roam quickly between Mobility Exchanges. FCC Federal Communications Commission: U.S. government agency that supervises, licenses, and controls electronic and electromagnetic transmission standards. The FCC Rules in Title 47 of the Code of Federal Regulations govern telecommunications in the United States. Wireless LANs must comply with Part 15 of the FCC rules, which are written specifically for RF devices. firmware Software instructions set permanently or semipermanently in ROM. FHSS Frequency Hopping Spread Spectrum: One of two types of spread spectrum radio technology used in wireless LAN (WLAN) transmissions. The FHSS technique modulates the data signal with a narrowband carrier signal that “hops” in a predictable sequence from frequency to frequency as a function of time over a wide band of frequencies. Interference is reduced, because a narrowband interferer affects the spread spectrum signal only if both are transmitting at the same frequency at the same time. The transmission frequencies are determined by a spreading (hopping) code. The receiver must be set to the same hopping code and must listen to the incoming signal at the proper time and frequency to receive the signal. FPGA Field Programmable Gate Array: An FPGA is a specially made digital semiconductor often used for prototyping. With an FPGA, a design engineer is able to program electrical connections on site for a specific application, without paying thousands of dollars to have the chip manufactured in mass quantities. FTP File Transfer Protocol: Defined in RFC 959, it is a Application protocol that is part of the TCP/IP protocol stack, used for transferring files between network nodes. gateway In the IP community, an older term referring to a routing device. Today, the term router is used to describe nodes that perform this function, and gateway refers to a special-purpose device that performs an application-layer conversion of information from one protocol stack to another. handoff The process of transferring the handling of that cellular call to the new base station.
C1n_Configuration_Manual_-_fm_1.0.0.x_for_US_&_Canada_20130116.doc Commercially Confidential 55 host address Logical address configured by an administrator or server on a device. Logically identifies this device on an internetwork. https Hypertext Transfer Protocol over Secure Sockets Layer: An Internet protocol developed by Netscape to encrypt and decrypt network connections to web servers. Built into all secure browsers, HTTPS uses the Secure Sockets Layer (SSL) protocol as a sublayer under the regular HTTP application layer, and uses port 443 instead of HTTP Port 80 in its interactions with the lower layer, TCP/IP. ICMP Internet Control Message Protocol: Defined in RFC 792, it is a Network layer Internet protocol that reports errors and provides other information relevant to IP packet processing. IEEE Institute of Electrical and Electronic Engineers: An American professional society whose standards for the computer and electronics industry often become national or international standards. In particular, the IEEE 802 standards for LANs are widely followed. infrastructure network In an infrastructure network, all communications are relayed through an AP (AP). Wireless devices can communicate with each other or with a wired network. The network is defined by the distance of mobile stations from the AP, but no restriction is placed on the distance between stations. Stations must request association with the AP to obtain network services, which the AP can grant or deny based on the contents of the association request. Like most corporate wireless LANs (WLANs), which must access a wired LAN for file servers and printers, Trapeze Networks Mobility System is an infrastructure network. IP Internet Protocol: Defined in RFC 791, it is a Network Layer protocol that is part of the TCP/IP stack and allows connectionless service. IP furnishes an array of features for addressing, type-of-service specification, fragmentation and reassembly, and security. IP address Often called an “Internet address”, this is an address uniquely identifying any device (host) on the Internet (or any TCP/IP network). Each address consists of four octets (32 bits), represented as decimal numbers separated by periods (a format known as “dotted-decimal”). Every address is made up of a network number, an optional subnetwork number, and a host number. The network and subnetwork numbers together are used for routing, while the host number addresses an individual host within the network or subnetwork. The network and subnetwork information is extracted from the IP address by using the subnet mask. There are five classes of IP addresses (A-E), which allocate different numbers of bits to the network, subnetwork, and host portions of the address. LOS Line Of Sight: Refers to the fact that there must be a clear, unobstructed path between the transmitters and receivers. This is essential for our LMDS products and enhances general performance in every RF deployment as opposed to partial or completely obstructed data paths. The opposite to LOS is NLOS, or Non Line Of Sight. MAC address Media Access Control address: A Data Link Layer hardware address that every port or device needs to connect to a LAN segment. These addresses are used by various devices in the network for accurate location of logical addresses. MAC addresses are defined by the IEEE standard, and their length is six characters, typically using the burned-in address (BIA) of the local LAN interface. Variously called “hardware address”, “physical address”, “burned-in address” or “MAC-layer address”. MTU Maximum Transmission Unit: The largest packet size, measured in bytes, that an interface can handle.
C1n_Configuration_Manual_-_fm_1.0.0.x_for_US_&_Canada_20130116.doc Commercially Confidential 56 NAT Network Address Translation: An algorithm instrumental in minimizing the requirement for globally unique IP addresses, permitting an organization whose addresses are not all globally unique to connect to the Internet, regardless, by translating those addresses into globally routable address space. NLOS Non Line Of Sight. Also known as obstructed path or pathway. noise Undesirable communications channel signals. NTP Network Time Protocol: Protocol built on top of TCP that ensures accurate local time-keeping with reference to radio and atomic clocks located on the Internet. This protocol is capable of synchronizing distributed clocks within milliseconds over long time periods. OFDM Orthogonal Frequency Division Multiplexing: A technique that splits a wide frequency band into a number of narrow frequency bands and sends data across the subchannels. The wireless networking standards 802.11a and 802.11g are based on OFDM. open system authentication The sender and the recipient do not share a secret key. Each party generates its own key-pair and asks the receiver to accept the (usually randomly) generated key. Once accepted, this key is used for a short time only, then a new key is generated and agreed upon. So, it is a two-step authentication method, in which sender first sends its identity and in response of that it gets the authentication results. ping Packet Internet Groper: ICMP echo message and its reply. Often used in IP networks to test the reach ability of a network device. PoE Power over Ethernet: A technology, defined in the developing IEEE 802.3af standard, to deliver dc power over twisted-pair Ethernet data cables rather than power cords. The electrical current, which enters the data cable at the power-supply end and comes out at the device end, is kept separate from the data signal so neither interferes with the other. Remote Bridge A bridge located on a network system separate from the host system. RF Radio Frequency: Any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation. RFC Request For Comments: Document series used as the primary means for communicating information about the Internet. Some RFCs are designated by the IAB as Internet standards. Most RFCs document protocol specifications, such as Telnet and FTP, but some are humorous or historical. RFCs are available online from numerous sources. shared key authentication Shared key authentication supports authentication of STAs as either a member of those who know a shared secret key or a member of those who do not. Shared key authentication accomplishes this with the use of the WEP privacy mechanism. Therefore, this authentication scheme is only available if the WEP option is implemented. The required secret, shared key is presumed to have been delivered to participating STAs via a secure channel that is independent of IEEE 802.11. During the shared key authentication exchange, both the challenge and the encrypted challenge are transmitted. This facilitates unauthorized discovery of the pseudorandom number (PRN) sequence for the key/IV pair used for the exchange. Implementations should therefore avoid using the same key/IV pair for subsequent frames.
C1n_Configuration_Manual_-_fm_1.0.0.x_for_US_&_Canada_20130116.doc Commercially Confidential 57 SNMP Simple Network Management Protocol: SNMP forms part of the Internet Protocol suite, as defined by the Internet Engineering Task Force (IETF). It is a Network management protocol used almost exclusively in TCP/IP networks. SNMP provides a means to monitor and control network devices, and to manage configurations, statistics collection, performance, and security. SNMP2 Simple Network Management Protocol Version 2: Version 2 of the popular network management protocol. SNMP2 supports centralized as well as distributed network management strategies, and includes improvements in the SMI, protocol operations, management architecture, and security. SSID Service Set Identifier: A 32-character (maximum) unique identifier attached to the header of packets sent over a WLAN that acts as a password when a mobile device tries to connect to the Basic Service Set. STP Spanning-Tree Protocol: Bridge protocol that uses the spanning-tree algorithm, enabling a learning bridge to dynamically work around loops in a network topology by creating a spanning tree. Bridges exchange BPDU messages with other bridges to detect loops, and then remove the loops by shutting down selected bridge interfaces. Refers to both the IEEE 802.1 Spanning-Tree Protocol standard and the earlier Digital Equipment Corporation Spanning-Tree Protocol upon which it is based. The IEEE version supports bridge domains and allows the bridge to construct a loop-free topology across an extended LAN. The IEEE version generally is preferred over the Digital version. subnet mask A 32-bit address mask used in IP to identify the bits of an IP address that are used for the subnet address. Using a mask, the router does not need to examine all 32 bits, only those selected by the mask. telnet The standard terminal emulation protocol within the TCP/IP protocol stack. Defined in RFC 854, it is a method of remote terminal connection, enabling users to log in to remote networks and use those resources as if they were locally connected. throughput Rate of information arriving at, and possibly passing through, a particular point in a network system. VAP Virtual Access Point: It is a logical entity that exists within a physical Access Point (AP). When a single physical AP supports multiple “Virtual APs”, each Virtual AP appears to stations (STAs) to be an independent physical AP, even though only a single physical AP is present. VLAN Virtual LAN: Group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. Because VLANs are based on logical instead of physical connections, they are extremely flexible. VLAN tag It works by tagging each frame, i.e. an Ethernet header extension that enlarges the header from 14 to 18 bytes. The VLAN tag contains the VLAN ID and priority. WDS can preserve the MAC address of client packets across links between accent points. WDS have to be enabled when repeater AP WDS is enabled.
C1n_Configuration_Manual_-_fm_1.0.0.x_for_US_&_Canada_20130116.doc Commercially Confidential 58 WEP Wired Equivalent Privacy: A security protocol for wireless local area networks (WLANs) defined in the 802.11b standard. WEP is designed to provide the same level of security as that of a wired LAN. LANs are inherently more secure than WLANs because LANs are somewhat protected by the physicalities of their structure, having some or all part of the network inside a building that can be protected from unauthorized access. WLANs, which are over radio waves, do not have the same physical structure and therefore are more vulnerable to tampering. WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another. However, it has been found that WEP is not as secure as once believed. WEP is used at the two lowest layers of the OSI model - the data link and physical layers; it therefore does not offer end-to-end security. Wi-Fi Wireless Fidelity: Wi-Fi is a label for devices conforming to the IEEE 802.11b standard for WLAN. The IEEE 802.11b standard has been published by the IEEE, which does not perform conformance testing. In order to establish such a conformance testing process, the Wi-Fi Alliance (formerly known as WECA) has been formed, which tests devices for conformance with the IEEE 802.11b standard and issues the Wi-Fi label for conforming devices. WME Wireless Multimedia Extensions: Also known as Wi-Fi Multimedia (WMM), it is a Wi-Fi Alliance interpretability certification, based on the IEEE 802.11e draft standard. It provides basic Quality of service (QoS) features to IEEE 802.11 networks. WMM prioritizes traffic according to 4 AC (Access Categories) - voice, video, best effort and background. However, it does not provide guaranteed throughput. It is suitable for simple applications that require QoS, such as Wi-Fi Voice over IP (VoIP) phone. WPA Wi-Fi Protected Access: WPA was created by the Wi-Fi Alliance in 2002, in part out of impatience with the slow-moving IEEE 802.11i standard. The industry consortium’s consensus was that an alternative to WEP was needed quickly, and WPA was the result. To avoid multiple standards and conflicts later on, WPA was designed from the get-go to be compatible with IEEE 802.11i and was based on its early draft specifications.
