 Managing the Radio  |  161  Aprisa SR+ User Manual 1.6.0 PO  QoS > Traffic Priority    TRAFFIC PRIORITY  Default Management Data Priority The Default Management Data Priority controls the priority of the Ethernet management traffic relative to Ethernet  customer  traffic.  It  can  be  set  to  Very  High,  High,  Medium  and  Low.  The  default  setting  is Medium. This priority is also used for traffic if the remote serial port is not available for the radio hardware data port option e.g. if the base station is 2E2S and a remote radio is 4E0S.  SERIAL PRIORITY This  parameter  controls  the  per  port  priority  of  the  serial  customer  traffic  relative  to  the  Ethernet customer  traffic.  If  equal  priority  is  required  to  Ethernet  traffic,  this  setting  must  be  the  same  as  the Ethernet Data Priority setting. The serial data priority can be set to Very High, High, Medium and Low. The default setting is Low.  A  queuing  system  is  used  to  prioritize  traffic  from  the  serial  and  Ethernet  interfaces  for  over  the  air transmission.  A  weighting  may  be  given  to  each  data  type  and  this  is  used  to  schedule  the  next transmission over the air e.g. if there are pending data packets in multiple buffers but serial data has a higher weighting it will be transmitted first. The serial buffer is 20 serial packets (1 packet can be up to 512 bytes). There are four priority queues in the Aprisa SR: Very High, High, Medium and Low. Data is added to one of these queues  depending on  the priority  setting. Data  leaves  the queues  from highest priority  to lowest: the Very High queue is emptied first, followed by High then Medium and finally Low.
162  |  Managing the Radio   Aprisa SR+ User Manual 1.6.0 PO  ETHERNET PRIORITY This  parameter  controls  the  per  port  priority  of  the  Ethernet  customer  traffic  relative  to  the  serial customer traffic. If equal priority is required to serial traffic, this setting must be the same as the Serial Data Priority setting. The  Ethernet  Priority  enables users  to  set the  priority  of Ethernet  port  ingress  frames.  The  priority for each port can be:  1.  From PCP priority bits (VLAN priority) in VLAN tagged frames or priority tag (VLAN 0) frames  2.  From DSCP priority bits in an IP packet (DSCP in IPv4 TOS field)  3. All frames are set to ‘very high’ priority 4. All frames are set to ‘high’ priority 5. All frames are set to ‘medium’ priority 6. All frames are set to ‘low’ priority The default setting is Low.  A queuing system is used to prioritize customer traffic from the serial and Ethernet interfaces for over the air  transmission.  A  weighting  may  be  given  to  each  data  type  and  this  is  used  to  schedule  the  next transmission over the air e.g. if there are pending data packets in multiple buffers but serial data has a higher weighting it will be transmitted first. The Ethernet buffer is 10 Ethernet packets (1 packet can be up to Ethernet MTU, 1536 bytes). There are four priority queues in the Aprisa SR+: Very High, High, Medium and Low. Data is added to one of these queues depending on the priority setting. Data leaves the queues from highest priority to lowest: the Very High queue is emptied first, followed by High then Medium and finally Low.   Default Priority When the priority of an Ethernet port uses the PCP bits (VLAN priority) values the ‘Default Priority’ option is enabled, allowing the priority of untagged VLAN frames to be set.  When  the  priority  of  an  Ethernet  port  uses  the  DSCP  priority  (in  IPv4  TOS  field)  values  the  ‘Default Priority’ option is enabled, allowing the priority of ARP frames to be set.
 Managing the Radio  |  163  Aprisa SR+ User Manual 1.6.0 PO  PRIORITY DEFINITIONS PCP (Priority Code Point) These  settings  provide  priority  translation  /  mapping  between  the  external  radio  LAN  VLAN  priority network  and the radio  internal  VLAN priority  network,  using the  VLAN  tagged  PCP (Priority  Code Point) priority field in the Ethernet/VLAN frame.    The IEEE 802.1Q specification defines a standards-based mechanism for providing VLAN tagging and class of  service  (CoS)  across  Ethernet  networks.  This  is  accomplished  through  an  additional  VLAN  tag,  which carries VLAN tag ID and frame prioritization information (PCP field), inserted within the header of a Layer 2 Ethernet frame. Priority Code Point (PCP) is a 3-bit field that indicates the frame priority level (or CoS). The operation of the PCP field is defined within the IEEE 802.1p standard, which is an extension of 802.1Q. The standard establishes  eight  levels  of  priority,  referred  to  as  CoS  values,  where  CoS  7  (‘111’  in  PCP  filed)  is  the highest priority and CoS 0 (‘000’) is the lowest priority.  The  radio  in  bridge  mode  used  the  PCP  value  in  the  VLAN  tag  to  prioritize  packets  and  provide  the appropriate QoS treatment per traffic type. The radio implements 4 priority queuing techniques that base its QoS on the VLAN priority (PCP). Based on VLAN priority bits, traffic can be put into a particular Class of Service (CoS) queue. Packets with higher CoS will always serve first for OTA transfer and on ingress/egress Ethernet ports. The ‘PCP priority definition’ tab is used to map ingress VLAN packet with PCP priority to the radio internal CoS  (priority). Since, in  most  of  the  cases  the  radio VLAN  network  is  connected  to  the corporate  VLAN networks,  the  network  administrator  might  like  to  have  a  different  VLAN  priority  scheme  of  the  radio network  CoS.  For  example,  management  traffic  in  the  multi-gigabit  corporate  VLAN  network  might  be prioritize with priority 7 (highest priority) and SCADA traffic with priority 5, but in the narrow bandwidth radio network, SCADA traffic will be map to radio very high CoS / priority (i.e. set PCP 5 = Very high) and management traffic might will be map to radio medium CoS / priority (i.e. set PCP 7 = medium) in order to serve first the mission-critical SCADA traffic over the radio network.
164  |  Managing the Radio   Aprisa SR+ User Manual 1.6.0 PO  This is done by mapping the external radio network VLAN priority to the internal radio CoS / priority using the ‘PCP priority definition’ tab. The radio support 4 queues, thus at maximum an 8 -> 4 VLAN priority / CoS mapping is done.  Default  mapping  of  ingress  packet  VLAN  priority  to  radio  CoS  /  priority  shown  in  the  ‘PCP  priority definition’ tab.
 Managing the Radio  |  165  Aprisa SR+ User Manual 1.6.0 PO  DSCP (Differentiated Services Code Point) These settings provide translation / mapping between the external radio IP priority network and the radio internal IP priority network, using the DSCP (DiffServ Code Point) priority field in the IP packet header.    Differentiated  Services  (DiffServ)  is  a  new  model  in  which  traffic  is  treated  by  routers  with  relative priorities based  on the IPv4 type of  services (ToS)  field. DSCP  (DiffServ Code  Point)  standard defined in RFC 2474 and RFC 2475. DiffServ increases the number of definable priority levels by reallocating bits of an IP packet for priority marking.  The DiffServ architecture defines the DiffServ (DS) field, which supersedes the ToS field in IPv4 to make per-hop  behaviour  (PHB)  decisions  about  packet  classification  and  traffic  scheduling  functions.  The  six most significant bits of the DiffServ field (in the IPv4 TOS field) is called as the DSCP. The standardized DiffServ  field  of  the  packet  is  marked  with  a  value  so  that  the  packet  receives  a  particular routing/forwarding treatment or PHB, at each router node. Using DSCP packet classification, traffic can be partition into multiple priority levels. The radio in router mode uses the DSCP value in the IP header to select a PHB behaviour for the packet and provide the appropriate QoS treatment. The radio implements 4 priority queuing techniques that base its  PHB  on  the  DSCP  in  the  IP  header  of  a  packet.  Based  on  DSCP,  traffic  can  be  put  into  a  particular priority / CoS (Class of Service) queue. Packets with higher CoS will always serve first for OTA transfer and on ingress / egress Ethernet ports. The ‘DSCP priority definition’ tab is used to map ingress IP packet with DSCP priority to the radio internal priority / CoS. Since, in most of the cases the radio routed network is connected to the corporate routed networks, the network administrator might like to have a different routed network priority scheme of the radio network, for example  management traffic in  the multi-gigabit corporate routed network  might be prioritize with DSCP EF (expedite forwarding) code (DSCP highest priority), and SCADA traffic with DSCP AF11 (assured forwarding) code (high priority), but in the narrow bandwidth radio network, SCADA traffic will be map to radio very high CoS / priority (i.e. set AF11 = Very high) and management traffic might map to radio low CoS / priority (i.e. set EF = Low)  in order to serve first the mission-critical SCADA traffic over the radio network.
166  |  Managing the Radio   Aprisa SR+ User Manual 1.6.0 PO  This is done by mapping the external radio network DSCP priority to the internal radio CoS / priority levels using the ‘DSCP priority definition’ tab. The radio support four queues, thus at maximum a 64 -> 4 CoS / priority mapping is done. Default mapping of ingress packet DSCP priority to radio CoS shown in the ‘DSCP priority definition’ tab. The radio maps all 64 DSCP values. The user can configure most common used 21 DSCP codes and the rest are mapped by default to low CoS / priority.
 Managing the Radio  |  167  Aprisa SR+ User Manual 1.6.0 PO  QoS > Traffic Classification These  settings  provide  multiple traffic  classification  profiles  based on classification  rules. Profiles for  a specific  traffic  type, protocol  or application can  be  assigned to  a  particular  VLAN and  CoS /  priority in bridge mode or to CoS / priority in router mode to provide the appropriate QoS treatment. For example SCADA traffic, management traffic, FTP traffic, can each have its own profile build with a set of classification rules. A profile can be build using multiple classification rules based on ports, Ethernet, IP,  TCP  /  UDP  headers  fields  (i.e.  L1/2/3/4  header  fields)  such  as:  Ethernet  port  #1,  VLAN  ID,  VLAN priority, IP DSCP Priority, MAC/IP address, TCP / UDP port fields to identify and classify the specific traffic type. When an ingress packet matches the profile L2/3/4 header fields settings, the packet is assigned to a particular VLAN  and CoS /  priority in  bridge mode  or to CoS  / priority  in router  mode to  provide the appropriate QoS treatment. The  radio  supports  four  CoS  /  priority  queues:  very  high,  high,  medium  and  low.  These  queues  are connected to a strict priority scheduler which dispatches packets from the queues out to the egress port by always serving first the ‘very high’ priority queue, whenever there is a packet in this queue. When the highest priority queue empties, the scheduler will serve the next high priority queues and so on. So when SCADA traffic is assigned to a ‘Very high’ priority, it will always served first and send over-the-air (OTA) whenever SCADA traffic enters to the radio, giving it the highest priority over other traffic type.  These settings are different for Bridge Mode and Router Mode.
168  |  Managing the Radio   Aprisa SR+ User Manual 1.6.0 PO  Bridge Mode Traffic Classification Settings    TRAFFIC CLASSIFICATION VLAN  bridge  mode traffic  classification  settings  provide  mapping  /  assigning  of profiles (set  by  rules to match a specific traffic type) to a VLAN ID and VLAN CoS / priority. The profile which is used to match to a specific  traffic type  will be identified in  the radio  network  by its associated VLAN ID  and  VLAN CoS  / priority to provide the appropriate QoS treatment. CoS / Priority can be set to very high, high, medium, low priority.    Profile name A free form field to enter the profile name with a maximum of 32 chars.  Assigned Priority Traffic  packets  that match  the  applied  profile  rules  will  be  assigned  to  the  selected  ‘assigned  priority’ setting of Very High, High, Medium and Low. This field cannot be set to Don’t Care. This applies profile rule mapping to the VLAN CoS / Priority with the appropriate internal radio assigned priority setting of Very High, High, Medium and Low.
 Managing the Radio  |  169  Aprisa SR+ User Manual 1.6.0 PO  Assigned VLAN ID Traffic packets  that match  the applied  profile rules  will be  assigned to  the selected  ‘assigned VLAN ID’ setting of VLAN ID in the range of 0 to 4095.  A VLAN ID of an ingress packet matching the classification rule (see ‘VLAN ID’ rule in next page) shall be changed to the ‘assigned VLAN ID’ setting, if below conditions are met: 1.  The VLAN ID of Ingress packet is same as PVID of the ingress port. 2.  Packet is received untagged at the port  If the VLAN ID of the tagged ingress packet is not the same as the PVID of the ingress port, then it shall not  be  changed  and  the  ‘assigned  VLAN  ID’  setting  is  ignored  i.e.  ingress  VLANs  will  pass-through unchanged.  If ‘assigned VLAN ID’ value is set in the ‘port VLAN membership’ under Ethernet > VLAN (port x tab), then this VLAN will be available for ingress and egress on the Ethernet and RF ports, otherwise this VLAN will only be available in one direction on the egress RF port. For example, if the base station Ethernet port 1 ‘assigned VLAN ID’ = 100 (VLAN-100) and it is also defined in the ‘port VLAN membership’ under Ethernet > VLAN (port 1 tab) and the remote sends a packet to the base with a VLAN of 100, this packet will be egress out to Ethernet port 1 (tagged or untagged based on the ‘egress action’ definition). If the VLAN-100 wasn’t set in the ‘port VLAN membership’, then the base station will drop a packet from the remote.  This setting parameter can be ‘Don’t Care’ (Assigned VLAN ID = 0) which means that the VLAN ID of ingress frame will never be modified.  Active Activates or deactivates the profile rule.   Controls The Save button saves all profiles to the radio. The Cancel button removes all changes since the last save or first view of the page if there has not been any saves.

186  |  Managing the Radio   Aprisa SR+ User Manual 1.6.0 PO  Key Encryption Key Summary  The security of over-the-air-rekeying depends on a truly random Key Encryption Key.  This is why the use of a Raw Hexadecimal key is recommended as a plain text phrase based on known spelling and grammar constructs  is  not  very random.  The  default  Key  Encryption  Key  is  provided only  to  allow  testing  of  the security  mechanism  and  is  not  intended  for  operational  use.  Using  the  default  Key  Encryption  Key undermines  the  security  of  the  AES  payload  encryption  because  an  attacker  using  the  default  Key Encryption Key would immediately recover the AES payload key after the first over-the-air-rekeying event.  When the Security Level is set to Strong, various protections are applied to the Key Encryption Key setting to prevent tampering.  In addition, the Key Encryption Key Type, Key Encryption Key Size, and the Key Encryption Key itself are  all  loaded from a customer prepared USB  key.   This is a one way operation to prevent key recovery from radios.  While the ability to save a Key Encryption Key to USB exists in Standard Security Level, the Strong Security Level Key Encryption Key is not compromised because the Strong Key Encryption Key is not the same as the Standard Security Level Key Encryption Key.

When  viewing  /  managing  the  details  of  the  users  via  SNMPv3,  the  standard  SNMP-USER-BASED-SM-MIB interface is used. This interface can be used to change the SNMPv3 Authentication Passphrase of the users. The SNMPv3 Authentication Passphrase of a user required to be changed cannot be changed by the same user i.e. a different user must be used for the transactions.  Generate New Keys from SNMPv3 USM User Passphrases Net-SNMP  is  a  suite  of  open  source  software  for  using  and  deploying  the  SNMP  protocol.    Similar functionality is built into many commercial SNMP managers. This next step of loading the Aprisa SR+  radios with keys generated from  USM user  passphrases requires the SNMPv3 USM Management utility provided as part of NET-SNMP. The utility is called ‘snmpusm’.  It provides a range of commands including the management of changing passwords for SNMPv3 users.  In order to use this utility, the user will need to install NET-SNMP on a Linux (or Windows®) or machine.  The examples below are from the Linux environment.  This tool automatically obtains the engine ID from the target radio before generating the keys and loading them into the target.

SNMPv3 Context Addressing  SNMPv3 is not user configurable and user can use this option with any NMS. The radio SNMP management interface  supports  SNMPv3/2  context  addressing.  The  SNMv3  context  addressing  allows  the  user  to  use secure SNMPv3 management while improving NMS performance. A NMS (Network Management System) can access any remote radio directly by using its IP address or via the base / master station SNMPv3 context addressing. The SNMPv3 context addressing can compress the SNMPv3 management traffic OTA (Over The Air) to the remote station by up to 90% relative to direct OTA SNMPv3 access to remote station, avoiding the radio narrow bandwidth traffic loading.

MIB files are supplied, and these can be  used by  a dedicated SNMP  Manager, such  as  Castle Rock’s  SNMPc, to  access  most of  the radio’s configurable parameters.  For  communication  between  the  SNMP  manager  and  the  radio,  Access  Controls  and  Community  strings must be set up as described in the following sections. A  SNMP  Community  String  is  used  to  protect  against  unauthorized  access  (similar  to  a  password).  The SNMP  agent  (radio  or  SNMP  manager)  will  check  the  community  string  before  performing  the  task requested in the SNMP message.  ACCESS CONTROL SETUP A SNMP Access Control is the IP address of the radio used by an SNMP manager or any other SNMP device to access the radio. The Aprisa SR+ allows access to the radio from any IP address.  Read Only The default Read Only community string is public.   Read Write The default ReadWrite community string is private.
 Managing the Radio  |  195  Aprisa SR+ User Manual 1.6.0 PO  SNMP Manager Setup  The  SNMP manager  community  strings  must  be  setup  to access  the  base station  and remote /  repeater stations.  To  access  the  base  station,  a  community  string  must  be  setup  on  the  SNMP  manager  the  same  as  the community string setup on the radio (see ‘Security > SNMP’ on page 194). SNMP access to remote / repeater stations can be achieved by using the radio’s IP address and the normal community string or by proxy in the base station.  SNMP Access via Base Station Proxy To access the remote / repeater stations via the base station proxy, the community strings must be setup on the SNMP manager in the format: ccccccccc:bbbbbb Where: ccccccccc is the community string of the base station and bbbbbb is the last 3 bytes of the remote station MAC address (see ‘Network Status > Network Table’ on page 271).  The SNMP  Proxy  Support  must be  enabled  for this  method  of SNMP  access  to operate  (see  ‘SNMP  Proxy Support’ on page 187).

 Managing the Radio  |  217  Aprisa SR+ User Manual 1.6.0 PO  Maintenance > Advanced    NETWORK  Node Registration Retry (sec) This parameter sets the base station poll time at startup or the remote / repeater station time between retries until registered. The default setting is 10 seconds.  Base Station Announcement Period (min) This  parameter  sets  the  period  between  base  station  polls  post  startup.  The  default  setting  is  1440 minutes (24 hours). When  a  new  base  station  powers  on,  it  announces  its  presence  and  each  remote  that  receives  the announcement message will be advised that a new base station is present and that they should re-register. This  allows  the  new  base  station  to  populate  its  Network  Table,  with  knowledge  of  the  nodes  in  the network. If, during this initial period, there is some temporary path disturbance to one or more remotes, they may miss the initial announcement messages and be left unaware of the base station change. For this reason, the base station must periodically send out announcement messages to pick up any stray nodes and the period of these messages is the base station Announcement Period. Setting this parameter to 0 will stop periodic announcement messages being transmitted.  If a critical parameter is changed in the base station, such as IP address, then the change is distributed to the network using base station announcement message. Note that in this case, an announcement is sent immediately independent of the Announcement Period setting.
218  |  Managing the Radio   Aprisa SR+ User Manual 1.6.0 PO  Node Missed Poll Count This parameter sets the number of times the base station attempts to poll the network at startup or if a duplicate IP is detected when a remote / repeater station is replaced. The default setting is 3.  Discover Nodes This parameter when activated triggers the base station to poll the network with Node Missed Poll Count and Node Registration Retry values.  Decommission Node(s) This  parameter  when  activated  resets  the  network  registrations  to  remove  the  entire  network  from service. Note: Take care using this option.   Broadcast Time This parameter when activated sends the base station Date / Time setting to all the remote and repeater stations in the network and sets their Date / Time. This option applies to the base station only.  Automatic Route Rediscovery This parameter enables the radio to transmit route discovery messages when packets are unacknowledged.  When  enabled,  unacknowledged  unicast  packets  are  converted  into  uni-broadcast  messages  and  sent through the network. All nodes see the message and populate their routing tables accordingly. When  the  destination  node  is  reached,  it  sends  a  route  response  message  via  the  shortest  path.  The intermediate nodes see this message and populate their routing tables in the reverse direction, thus re-establishing the route. The default setting is disabled.  GENERAL Frequency Tracking Frequency  Tracking  enables  the  receiver  to  track  any  frequency  drift  in  the  transmitter  to  maintain optimum SNR and radio link performance over the full temperature range. When enabled, remote  stations  adjust their  receive  frequency  to the  frequency  of the incoming packet rate and the base station notifies remote stations if their transmit frequency requires adjustment. The default setting is Enabled.
 Managing the Radio  |  219  Aprisa SR+ User Manual 1.6.0 PO  MAINTENANCE FILES  There are three maintenance file types which can saved / restored to / from PC or USB flash drive:  Note: Some brands of USB flash drives may not work with 4RF radios.  File - Configuration Settings Action  Action Option Save to PC This saves the file with a filename of ‘Config.4’ to a binary encrypted file. This can then be saved from the Browser popup (example is Windows Internet Explorer 11). The file should be renamed to be able to identify the radio it was saved from.    Save to Radio USB This saves the file with a filename of ‘asrcfg_1.6.0’ to a binary encrypted file on the radio USB flash drive root directory. Restore from PC This restores all user configuration settings from a binary encrypted file on a PC directory to the radio. A reboot warning message will warn of a pending reboot after the PC file is selected. Clicking OK will open a browser file selection window to select the file.  Note: If you are using Explorer, it must be IE10 or above for this feature to work correctly. Restore from Radio USB This restores all user configuration settings from a binary encrypted file on the USB root directory to the radio.  Note:  ‘Payload  Encryption  Key’  and  ‘Key  Encryption  Key’  parameters  (see  ‘Security  >  Setup’)  are  not saved  to  the  configuration  file.  When  a  ‘Restore  from  PC’  or  ‘Restore  from  Radio  USB’  is  used,  these parameters  will  retain  their  existing  values  so  are  not  changed  by  the  operation  of  restoring  the configuration file.
220  |  Managing the Radio   Aprisa SR+ User Manual 1.6.0 PO  File - Event History Log Action  Action Option Save to PC This saves the file with a filename of ‘Info.tar.gz’ to a binary encrypted file. This can then be saved from the Browser popup (example is Windows Internet Explorer 11). The file should be renamed to be able to identify the radio it was saved from. The ‘gz’ file is normally for sending back to 4RF Limited for analysis but can be opened with WinRar.    Save to Radio USB This saves the file with a filename of e.g. ‘alarm_173.10.1.30_2014-11-10,15.54.14.txt’ to a text file on the radio USB flash drive root directory.
 Managing the Radio  |  221  Aprisa SR+ User Manual 1.6.0 PO  File - Configuration Script Action  Action Option Load and Execute This loads and executes configuration script files. There are sample configuration script files on the product CD in a directory called ‘Master Configuration’. The purpose of these files is to use as templates to create your own configuration scripts. Note: Be careful using this feature as incompatible configurations will change the radios settings and break radio connectivity.  Note: Activating this function will over-write all existing configuration settings in the radio (except for the non-saved  settings  e.g.  security  passwords,  licence  keys  etc)  without  any  verification  of  the  command setting  in  the  radio.  Precautions  should  be  taken  to  prevent  radio  outages  with  incorrect  radio configurations. The following process steps are recommended: a.  Save the current radio configuration to a PC or USB before uploading the new configuration script file b.  Upload the new configuration script file to the radio  c.  If  for  some  reason  the  radio  doesn’t  work  as  expected,  the  saved  configuration  file  can  be uploaded to the radio (roll back to previous configuration).  Retain IP Address This  parameter  when  enabled  ensures  that  the  radio  IP  address  is  not  changed  when  the  radio configuration settings are restored from a configuration file with a different IP radio address. It prevents the radio losing connectivity when the configuration settings are restored from a configuration file.  Revert Config if Connection Lost When the Maintenance Files feature is used on remote radios from the base station, this parameter allows the configurations to be restored to the previous configuration if the connection is lost. This must be set before executing the Configuration Settings / Configuration Script restore functions.

Severity Function Critical The Critical severity level indicates that a service affecting condition has occurred and an  immediate  corrective  action  is  required.  Such  a  severity  can  be  reported,  for example, when a managed object becomes totally out of service and its capability must be restored. Major The Major severity level indicates that a service affecting condition has developed and an urgent  corrective action is required. Such a severity can be reported, for example, when there is a severe degradation in the capability of the managed object and its full capability must be restored. Minor The  Minor  severity  level  indicates  the  existence  of  a  non-service  affecting  fault condition and that corrective action should be taken in order to prevent a more serious (for example, service affecting) fault. Such a severity can be reported, for example, when the detected alarm condition is not currently degrading the capacity of the managed object. Warning The Warning  severity level indicates the detection of a potential or impending service affecting fault, before any significant effects have been felt. Action should be taken to further  diagnose  (if  necessary)  and  correct  the  problem  in  order  to  prevent  it  from becoming a more serious service affecting fault.

The  radio  implemented ARP protocol is used for resolution of network layer addresses into link layer addresses. It is used to map a IPv4  address  to  an  Ethernet  MAC address.  The  ARP  table shows  the  results  of  the ARP  protocol  linkage between IPv4 address and Ethernet MAC address of the devices attached to the radio. In a layer 2 bridge LAN, an upper layer protocol may include the IP address of the destination, but since it is  an Ethernet LAN network,  it also  needs  to know  the  destination  MAC address.  First,  the  radio  uses a cached  ARP table  to  look up  the  IPv4 destination address  for the  matching  MAC address  records. If  the MAC  address  is  found,  it  sends  the  IPv4  packet  encapsulated  in  Ethernet  frame  with  the  found  MAC address. If the ARP cache table did not produce a result for the destination IPv4 address, the radio sends a broadcast  ARP  message  requesting  an  answer  (of  MAC  address  that  matches)  for  IP  address.  The destination device responds with its MAC address (and IP). The response information is cached in  radios’ ARP table and the message can now be sent with the appropriate destination MAC address.    ADDRESS TABLES  Title Function IP Address The IPv4 address of a neighboring device in the radio LAN network  MAC Address The ARP result matching or mapping MAC address from the IPv4 address.

In order for the radio to switch frames between Ethernet LAN ports efficiently, the radio layer 2 bridge  maintains  a  MAC  address  table.  When  the  radio  bridge  receives  a  frame,  it  associates  the  MAC address of the sending network device with the LAN port on which it was received. The bridge dynamically learns and builds the MAC address table by using the MAC  source address of  the frames received. When the radio bridge receives a  frame for a MAC  destination address not listed in its address table, it floods the frame to all LAN ports of the same LAN  (or in case of VLAN, to the specific VLAN)  except  the  port  that  received  the  frame.  When  the  destination  bridge  device  replies,  the  radio bridge  adds  its  relevant  MAC  source  address  and  interface  port  number  to  the  MAC  address  table.  The switch then forwards subsequent frames to a single LAN port without flooding all LAN ports.    ADDRESS TABLES  Title Function MAC Address The learned MAC address of a neighboring bridge device in the LAN network. Interface The Ethernet port interface the MAC address has learned  Age left The aging time of this MAC entry will stay in the table, even if this MAC address is not used.

278  |  Managing the Radio   Aprisa SR+ User Manual 1.6.0 PO  Protected Station The majority of  SuperVisor  screens are  the same  for the  standard  radio and  the protected  station. The following screens are specific to the protected station.  Logging into a Protected Station When SuperVisor detects a protected station, it operates in Single Session Management operation mode.  When in Single Session Management mode, SuperVisor will automatically detect the two individual Aprisa SR+  radios  configured  to  pair  together  for  protection,  and  manage  the  two  units  in  a  single  browser session.  To the user, it will appear as managing a single unit, but SuperVisor will interact with the two individual units at a lower level. The user can login with the IP address of either the Primary or Secondary radio to manage the protected station  (don’t  use  the  PVIP  address  as  it  is  not  a  management  IP  address).  SuperVisor  will  present  all information  appropriately  where  ‘Common  Parameters’  will  be  presented  to  the  user  as  a  single parameter  e.g.  TX  and  RX  Frequencies  and  ‘Unit  Specific  Parameters’  will  be  presented  to  the  user  as Primary or Secondary parameters e.g. Events and Alarms. When saving data, SuperVisor will also validate and ensure that the correct settings are written to both units.  The  SuperVisor  Single  Session  Management  ensures  that  both  units  of  the  protected  station  are always configured correctly to complement each other as protected partners. The user can still login with two different sessions to the active and standby radios. If the user opens two session management, one session logged into the active radio and a second session logged into the standby radio, the Multiple Management Sessions pop-up message will show the user names and IP addresses of the active and standby radio.  Parameter Errors On  protected  station  screens,  parameter  values  displayed  in  red  indicate  discrepancies  in  common parameter  values  between  the  primary  and  secondary  radios  (see  ‘Protected  Station:  Terminal  > Summary’  on  page  279 for  an  example  of  the  red  display).  The  value  displayed  is  from  the  ‘addressed radio’. These value discrepancies can occur if the two protected station radios have been separately configured. The  discrepancies  can  be  corrected  by  re-entering  the  values  in  one  of  the  radios.  The  value  will  be copied to the partner radio.

282  |  Managing the Radio   Aprisa SR+ User Manual 1.6.0 PO  Protected Station: Terminal > Operating Mode    OPERATING MODES Terminal Operating Mode The  Terminal  Operating  Mode  can  be  set  to  Base,  Base  Repeater,  Repeater,  Remote  or  Point-To-Point station. The default setting is Remote.  Option Function Base The base station manages all traffic activity between itself, repeaters and remotes. It is the center-point of network where in most cases will be connected to a SCADA master. Base Repeater The Base-Repeater has the same function as the base station (and repeater station), but used when peer to peer connections between remotes is required via the base station. Base MMS The Base-MMS has the same function as the base station, but used when Migration Master Station operation is required (see Aprisa SR+ MMS User Manual). Repeater The repeater forwards packets coming from base station and other repeaters e.g. in daisy chain LBS mode and /or remote stations. Remote The remote in most cases is used as the end-point of the SCADA network connected to an RTU or PLC device for SCADA network control and monitoring. Point To Point Configures a full duplex radio for Point-To-Point (PTP) operation. Changing from PMP or PTP or vice versa requires the radio to be ‘restored to factory default settings’ which will clear all previous radio setup and configuration. See Aprisa SR+ User Manual 1.6.0 PTP for all Point-To-Point setup and configuration.
 Managing the Radio  |  283  Aprisa SR+ User Manual 1.6.0 PO  Ethernet Operating Mode The  Ethernet  Operating  Mode  defines  how  Ethernet  /  IP  traffic  is  processed  in  the  radio.  The  default setting is Bridge.  Option Function Bridge Bridge mode inspects each incoming Ethernet frame source and destination MAC addresses to determine if the frame is forwarded over the radio link or discarded. Gateway Router Gateway Router mode inspects each incoming IP source and destination IP addresses to determine if the packet is forwarded over the radio link or discarded. In this mode, all Ethernet interfaces have the same IP address and subnet. Router Router mode inspects each incoming IP source and destination IP addresses to determine if the packet is forwarded over the radio link or discarded. In this mode, each Ethernet interface has a different IP address and subnet.  SR Compatible The SR Compatible option enables over-the–air point-to-multipoint interoperation between an Aprisa SR+ network and New Aprisa SR radios. The default setting is unticked. When the Aprisa SR+ ‘SR Compatible’ option is activated, the Aprisa SR+ locks its modulation to QPSK (as per the New Aprisa SR modulation) and disables functionality which is not available in  the New Aprisa SR for full compatibility / interoperability operation. This  compatibility  option  allows  the  user  a smooth migration  to  Aprisa SR+  when  higher  speeds  of  120, 60 kbit/s (at 25, 12.5 kHz channel sizes), Adaptive Coding and Modulation, full duplex and more features are required.

Redundant (Protected Station) The SR+ radio is part of an Aprisa SR+ Protected Station. The RF ports and interface ports from two standard Aprisa SR+ radios are switched to the standby radio if there is a failure in the active radio Monitored Hot Standby (Protected Station) Set to make this SR+ radio part of an Aprisa SR+ Protected Station. The RF ports and interface ports from two standard Aprisa SR+ radios are switched to the standby radio if there is a failure in the active radio. The standby radio is monitored to ensure its correct operation should a switch-over be required. See ‘Monitored Alarms’ on page 333 for the list of monitored alarms. Serial Data Driven Switching The SR+ radio is part of an Aprisa SR+ Data Driven Protected Station. Provides radio and RS-232 serial port user interface protection for Aprisa SR+ radios.  Automatic Periodic Switch Duration The Automatic Periodic Switch Duration sets the time interval for automatic switch-over from the active radio to the standby radio. This  feature  will  automatically  switch-over  from  the  active  radio  to  the  standby  radio  if  there  are  no alarms  preventing  the  switch-over  to  the  standby  radio.  It  can  be  used  to  provide  confidence  that  the standby radio is still operational maybe after many days of standby operation. The maximum number of days that can be set is 49 days. The default setting is 0 which disables the automatic switch-over feature.

290  |  Managing the Radio   Aprisa SR+ User Manual 1.6.0 PO  Protected Station Virtual IP Address (PVIP) The  Protected  Station  Virtual  IP  Address  (PVIP)  is  the  IP  Address  of  the  active  radio  whether  it  is  the primary radio or the secondary radio. The PVIP is available in both bridge and router modes. In router mode, the PVIP can be used as ‘next hop’ IP address by external routers to reach the protected station so the protection station switch will always be transparent to the external devices and routers. In both bridge and router modes, the PVIP is used in terminal server mode in remote protected stations. The PVIP is used to reach the protected remote station from the SCADA master connected to base station in terminal server mode. Note:  The radio IP address should be used for SNMP management as using the PVIP for SNMP management will result in undefined behaviour if a switch-over occurs during an SNMP transaction. Thus, using PVIP for SNMP network management is not recommended. After a switch-over, new active radio owns the PVIP and will send out a gratuitous ARP to clear the MAC learning tables of upstream switches/routers. Set the static IP Address of the PVIP using the standard format xxx.xxx.xxx.xxx. The default IP address is 0.0.0.0.  Subnet Mask Set the Subnet Mask of the radio using the standard format xxx.xxx.xxx.xxx. The default subnet mask is 255.255.0.0.  Gateway Set  the  Gateway  address  of  the  radio,  if  required,  using  the  standard  format  xxx.xxx.xxx.  The  default Gateway is 0.0.0.0.
 Managing the Radio  |  291  Aprisa SR+ User Manual 1.6.0 PO  RADIO INTERFACE IP SETTINGS  The RF interface IP address is the address that traffic is routed to for transport over the radio link. This IP address is only used when Router Mode is selected i.e. not used in Bridge Mode. Radio Interface IP Address Set the IP Address of the RF interface using the standard format xxx.xxx.xxx.xxx. The default IP address is in the range 10.0.0.0.  Radio Interface Subnet Mask Set the  Subnet  Mask of  the RF  interface  using  the standard format  xxx.xxx.xxx.xxx.  The default  subnet mask is 255.255.0.0 (/16).  Note 1: If the base station RF interface IP address is a network IP address, and if the remote radio is also using a network IP address within the same subnet or different subnet, then the base radio will assign an automatic RF interface IP address from its own subnet. When the base radio has  a host specific RF interface IP address, then all the remotes must  have a host specific RF interface IP address from the same subnet. Note  2:  When a  remote radio is configured for  Router Mode  and the base  radio is  changed from Bridge Mode  to Router  Mode  and  the  RF  interface IP  address is  set  to AUTO  IP configuration  (at  least the  last octet of the RF interface IP address is zero), it is mandatory to configure the network topology by using the ‘Decommission Node’ and ‘Discover Nodes’ (see ‘Maintenance > Advanced’ on page 217).
