Aprisa SR User Manual

Packet Size (Bytes)

This parameter sets the maximum over-the-air packet size in bytes. A smaller maximum Packet Size is
beneficial when many remote stations or repeater stations are trying to access the channel. The default
setting is 1550 bytes.

As radios dispatched from the factory have a Packet Size set to the maximum value of 1550 bytes, if a new
radio is installed in an existing Field Access Network (network), the Packet Size must be changed to ensure
it is the same value for all radios in the network. The new radio will not register an existing network if the
Packet Size is not the same as the other radios in the network.

This packet size includes the wireless protocol header and security payload (0 to 16 bytes). The length of
the security header depends on the level of security selected.

When the security setting is 0, the maximum user data transfer over-the-air is 1516 bytes.

When encryption is enabled, the entire packet of user data (payload) is encrypted. If authentication is
being used, the security frame will be added (up to 16 bytes). The wireless protocol header is then added
which is proprietary to the Aprisa SR. This is not encrypted.

Packet Time to Live (ms)

This Time To Live (TTL) parameter sets the time a packet is allowed to live in the system before being
dropped if it cannot be transmitted over the air. It is used to prevent old, redundant packets being
transmitted through the Aprisa SR network. The default setting is 1500 ms.

In the case of serial poll SCADA networks such as MODBUS and IEC 60870.50.101, it is important to ensure
the replies from the RTU are in the correct sequence and are not timed out replies from Master requests.
If the TTL value is too long, the SCADA master will detect sequence errors.

It is recommended to use a TTL which is half the serial SCADA timeout. This is commonly called the ‘scan
timeout’ or ‘link layer time out’ or ‘retry timeout’.

When using TCP protocols, a TTL of 1500 ms is recommended because a TCP re-transmission usually occurs
after approximately 3 second.

In SCADA networks which use both serial and Ethernet, it is recommended that the TTL is set to half the
serial SCADA timeout for serial remotes, and 1500 ms for Ethernet (TCP) remotes. For example, if the
serial SCADA timeout is 1000 ms, a remote radio which is connected to the serial RTU should be set to
500 ms, a remote radio which is connected to a Ethernet (TCP) RTU should have a 1500 ms timeout.

In this case, the base station TTL should be set to 1500 ms as well; or which ever is the longer TTL of
serial or Ethernet.

Aprisa SR User Manual

Option

Function

Disabled

Every packet received by the radio will be forwarded to the
relevant interface.

Automatic

The radio will filter (discard) packets not destined for itself
according to the Aprisa SR traffic protocols

Option

Function

Broadcast

Serial port traffic from the network is broadcast on all serial ports
on this radio. This will include the RS-232 port derived from the
USB port.

Segregate

Serial port traffic from the network from a specific port number is
directed to the respective serial port only.

Packet Filtering

Each Aprisa SR radio can filter packets not destined for itself. The Packet Filtering parameter controls this
functionality.

In an Aprisa SR network, all communication from remote stations is destined for the base station in the
Aprisa SR network communication protocol. In a repeater network, a remote station will send a message
to the base station. The repeater station will receive this and then repeat the message. The repeated
message will then be received by the base station. Other remote stations connected to the repeater
station will receive this message and depending on the Packet Filtering parameter, either forward this
packet or discard it.

This filtering capability can provide the ability for remote stations to communicate with each other when
connected to a repeater, particularly useful in the event of losing communication with a SCADA Master,
assuming the Aprisa SR network is still operational.

Note: IP Header Compression must be disabled for this feature to operate correctly (see ‘IP Header
Compression Ratio’ on page 101).

The default setting is Automatic.

Note: The Aprisa SR network is transparent to the protocol being transmitted; therefore the Packet
Filtering parameter is based on the Aprisa SR addressing and network protocols, not the user (SCADA, etc.)
traffic protocols.

Serial Data Stream Mode

This parameter controls the traffic flow in the radio serial ports.

The default setting is Broadcast.

Aprisa SR User Manual

TRAFFIC SETTINGS

Serial Data Priority

The Serial Data Priority controls the 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 (see ‘Ethernet Data Priority’ on page 100).

The serial data priority can be set to Very High, High, Medium and Low. The default setting is Very High.

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 Data Priority

The Ethernet Data Priority controls the 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 (see ‘Serial Data Priority’ on page 100)

The Ethernet Data Priority can be set to Very High, High, Medium and Low. The default setting is Very
High.

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, 1500 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 Management Priority

The Ethernet Management Priority controls the priority of the Ethernet management traffic relative to
Ethernet customer traffic.

The Ethernet Management Priority can be set to Very High, High, Medium and Low. The default setting is
Medium.

Option

Function

Compression
Disabled

Disables IP Header Compression.

High

State information is synchronized less frequently thus achieving
the best compression ratio.

Medium

State information is synchronization less frequently than ‘High’
setting but more frequently than ‘Low’ setting.

Low

State information is synchronized frequently thus reducing the
compression ratio.

Background Bulk Data Transfer Rate

This parameter sets the data transfer rate for large amounts of management data.

The default setting is high.

DATA COMPRESSION

IP Header Compression Ratio

The IP Header Compression implements TCP/IP ROHC v2 (Robust Header Compression v2. RFC4995,
RFC5225, RFC4996) to compress the IP header. IP Header Compression allows for faster point to point
transactions, but only in a star network.

IP Header Compression module comprises of two main components, Compressor and Decompressor. Both
these components maintain some state information for an IP flow to achieve header compression.
However, for reasons like packet drops or station reboots this state information can go out of sync
between compressor and decompressor resulting in compression and/or decompression failure resulting in
loss of packets.

The Compression Ratio controls the rate at which compressor and decompressor synchronize state
information with each other. Frequent synchronization results in reduced ratio.

The default setting is High.

When IP Header Compression is enabled, it is important that the Network Radius is set correctly. If it was
incorrectly set to 1, header compression could not be interpreted by radius 2 radios.

Aprisa SR User Manual

SNMPv3 Authentication Passphrase

The Authentication Passphrases can be changed via SNMP (not SuperVisor).

When viewing / managing the details of the users via SNMP, the standard SNMP-USER-BASED-SM-MIB
interface is used. This interface can be used to change the Authentication Passphrase of the users.

The Authentication Passphrase of the user required to be changed cannot be changed by the same user i.e
a different user must be used for the transactions.

To change a user authentication passphrase:

1. SET the usmUserStatus object for that user to ‘Not In Service’

2. GET the usmUserSpinLockobject

3. SET the usmUserSpinLockobject with the value that was just GOT in the previous step

4. SET the usmUserAuthKeyChange to the new Authentication key string

5. SET the usmUserPrivKeyChangeto the new Privacy key string

6. SET the usmUserStatus object for that user to ‘Active’

Note that the key string for steps 4 and 5 are 32 octet hexadecimal values. This string is generated based

on the ‘old passphrase’ and ‘new passphrase’ as specified in RFC2274.

The utility ‘encode_keychange.exe’, available from NET-SNMP open source applications, can be used to

generate this string.

An example command to generate a new Authentication key string for the default desUserMD5 is:

encode_keychange –t md5 –O “desUserMD5” –N “desUserMD5Auth” –E 0x0100DC

An example command to generate a new Privacy key string for the default desUserMD5 is:

encode_keychange –t md5 –O “desUserMD5” –N “desUserMD5Priv” –E 0x0100DC

These command executions will return a 32 Octet Hexadecimal string that can be used in steps 4 and 5
above.

Security > SNMP

In addition to web-based management (SuperVisor), the network can also be managed using the Simple
Network Management Protocol (SNMP). 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 | 125

Aprisa SR User Manual

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 124).

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 167) for the remote station MAC address.

The SNMP Proxy Support must be enabled for this method of SNMP access to operate (see ‘SNMP Proxy
Support’ on page 120).

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.

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

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.

RF Interface MAC address

This parameter is only applicable when the radio is part of a Protected Station.

This RF Interface MAC address is used to define the MAC address of the Protection Switch. This address is
entered into both Protected Station radios in the factory.

If a replacement Protection Switch is installed, the replacement unit MAC address must be entered in both
radios (see ‘Replacing a Faulty Protection Switch’ on page 37).

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

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 156).

1. To ensure that the Network Table is up to date, it is recommended running the node discover function
(see ‘Discover Nodes’ on page 142).

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.

This page is used to manage the activation of that software pack on all remote radios on the network.

This page is only available when the radio is configured as a Base Station.

REMOTE SOFTWARE ACTIVATION

When the software pack version has been distributed to all the remote stations, the software is then
activated in all the remote stations with this command. If successful, then activate the software pack in
the base station to complete the network upgrade.

Version

This parameter displays the software version for activation. The default version is the software pack
version but any valid software version can be entered in the format ‘n.n.n’.

To activate software in 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 156) and distributed to all remote radios in the network.

Note: Do not navigate SuperVisor away from this page during the activation process (SuperVisor can lose
