Configuring RADIUS accounting using the CLI
The Nortel SNAS 4050 can be configured to provide support for logging
administrative operations and user session start and stop messages to a RADIUS
accounting server.
With RADIUS accounting enabled, the Nortel SNAS 4050 sends an accounting
request start packet to the accounting server for each user who successfully
authenticates to the Nortel SNAS 4050 domain. The start packet contains the
following information:
• client user name
• Nortel SNAS 4050 device Real IP address (RIP)
•session ID
When the user session terminates, the Nortel SNAS 4050 sends an accounting
request stop packet to the accounting server. The stop packet contains the
following information:
•session ID
•session time
• cause of termination
Configure the RADIUS server in accordance with the recommendations in
RFC 2866.
Certain Nortel SNAS 4050-specific attributes are sent to the RADIUS server
when you enable accounting (see “Configuring Nortel SNAS 4050-specific
attributes using the CLI” on page 149). In conjunction with custom plugins on
RADIUS, these attributes can be used for more detailed monitoring of Nortel
SNAS 4050 activity.
