Radius Server Agent Configuration(3.1)

The Radius Server agent configuration consists of two tabs:

  • NAS
  • Miscellaneous

NAS Tab

The list on the NAS tab can be dynamically updated.

In the NAS tab, all NASes that the agent collects information from, are specified.

SettingDescription

Host Address

The IP address or hostname that the NAS, sending packets, is located on.

Secret Key

Key used for authentication of a received packet. This key must be identical to the one defined in the NAS.

Miscellaneous Tab

The Miscellaneous tab consists of the following settings:

ItemDescription

Port

The port number where the Radius Server agent will listen for packets from the NAS(es).

Note!

Since the NASes will be configured to communicate with a specific host on this port, it is important that the workflow containing the Radius Server agent is configured to execute on the associated EC for that host.

Two Radius agents may not be configured to listen on the same port, on the same host.

PDU Lifetime (millisec)

If set to a value larger than 0 (zero), duplicate check is activated. The buffer saved for comparison is the packets collected during the set time frame.

Skip MD5 Calculation

When enabled, the check for MD5 signatures is excluded. This is necessary if the Radius client does not send MD5 signatures along with the packets, in which case they would be discarded by the Radius Server agent.

Note!

When the Skip MD5 Calculation option is enabled, the authenticator field in all response messages will be 0 (zero).

Duplicate Check

Checking for duplicate packets can be made based on:

  • Radius Standard - the identifier within the packet (byte number 2).

  • CRC32 - checksum for the complete packet.

When a duplicate is detected, it is silently thrown away (no message is logged) and the Radius agent responds as if a normal packet was received.

Error HandlingSelect an Error Route to ensure that all rejected packets are routed into the workflow using this route.

Note!

See Handling of UDP traffic for Radius to know how UDP traffic is handled for Radius Server Agent.
