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.

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.

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.
Aprisa SR+ User Manual 1.6.0 PO
164 | Managing the Radio
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.

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
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.

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.

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.
Aprisa SR+ User Manual 1.6.0 PO
Managing the Radio | 169
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.

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.

SNMPv3 Authentication Passphrase
The SNMPv3 Authentication Passphrase can be changed via the SNMPv3 secure management protocol
interface (not via SuperVisor).
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.
functionality is built into many commercial SNMP managers.
Similar
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.

Summary
It is necessary to record the new passphrases loaded into the Aprisa SR+ radios and then load the
passphrases into the SNMP manager. There is a separate passphrase for the two supported forms of
authentication (MD5 and SHA1) only as well as the two forms of authentication used in combination the
two forms of encryption (DES and AES). It is vital to change all passphrases even if the depreciated
mechanism are not used (MD5 and DES) otherwise an attacker could still use the default passphrases.

Reset Unknown Passphrases with the Command Line Interface
As it is not possible for users to read previously set passphrases, a CLI command is available from Aprisa
SR+ software release 1.4.0 to ‘reset’ the SNMPv3 USM users back to defaults.
Note: USM users are not related to CLI and SuperVisor users. This command will only be accessible to the
CLI ‘admin’ user logins.
To reset unknown passphrases:
1. Telnet into each radio in the network and via the CLI reset the passphrases
2. Login to the radio with:
Login: admin
Password: *********
3. Set all SNMP3 users to default values with the ‘snmpusm reset’ command (see ‘SNMP3 users to default
values’ below for the list of default values).

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.

Security > SNMP
In addition to web-based management (SuperVisor), the network can also be managed using the Simple
Network Management Protocol (SNMP) using any version of SNMP v1/2/3. 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.
Aprisa SR+ User Manual 1.6.0 PO
Managing the Radio | 195
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).

Security > RADIUS
This page displays the current settings for the Security RADIUS.
RADIUS - Remote Authentication Dial In User Service
RADIUS is a client / server system that secures the radio link against unauthorized access. It is based on
open standard RFCs: RFC 2865/6, 5607, 5080 and 2869. It is used for remote user Authorization,
Authentication and Accounting.
When a user logs into a radio with RADIUS enabled, the user’s credentials are sent to the RADIUS server
for authentication of the user.
Transactions between the RADIUS client and RADIUS server are authenticated through the use of a shared
secret, which is never sent over the network.
For a RADIUS server to respond to the radio, it must configured with and respond to the following
Management-Privilege-level attributes:
Admin Level = 4
Technician Level = 2
Viewer Level = 1
A RADIUS server can act as a proxy client to other RADIUS servers or other kinds of authentication servers.

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.

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 reestablishing 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.

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

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.

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.

Start Transfer
This parameter when activated distributes (broadcasts) the new Software Pack to all remote stations in
the network.
Note: The distribution of software to remote stations does not stop customer traffic from being
transferred. However, due to the volume of traffic, the software distribution process may affect customer
traffic.
Software distribution traffic is classified as ‘management traffic’ but does not use the Ethernet
management priority setting. Software distribution traffic priority has a fixed priority setting of ‘very
low’.
To distribute software to remote stations:
This process assumes that a Software Pack has been loaded into the base station with the file transfer
process (see ‘Software > File Transfer’ on page 238).
1. To ensure that the Network Table is up to date, it is recommended running the node discover function
(see ‘Discover Nodes’ on page 218).
2. Click on ‘Start Transfer’.
Note: This process could take anywhere between 40 minutes and several hours depending on channel size,
Ethernet Management Priority setting and the amount of customer traffic on the network.
3. When the distribution is completed, activate the software with the Remote Software Activation.
Pause Transfer
This parameter when activated, pauses the distribution process and shows the distribution status. The
distribution process will continue from where it was paused with Resume Transfer.
Cancel Transfer
This parameter when activated, cancels the distribution process immediately.
During the distribution process, it is possible to navigate away from this page and come back to it to check
progress. The SuperVisor session will not timeout.

Monitoring > Address Tables
ARP Table
This page displays the current Address Resolution Protocols (ARP) on the radio. 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.

Ethernet MAC Learning Table
This page displays the current Ethernet Media Access Control (MAC) Address table on the radio LAN
network. 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.

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.

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.
Aprisa SR+ User Manual 1.6.0 PO
Managing the Radio | 283
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.

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.

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.
Aprisa SR+ User Manual 1.6.0 PO
Managing the Radio | 291
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).
