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 
). In conjunction with custom plugins on 
RADIUS, these attributes can be used for more detailed monitoring of Nortel 
SNAS 4050 activity.
