802.1X Accounting Attribute-Value Pairs - Cisco Catalyst 2960-XR Security Configuration Manual

Configuring IEEE 802.1x Port-Based Authentication
The switch does not log 802.1x accounting information. Instead, it sends this information to the RADIUS
server, which must be configured to log accounting messages.

802.1x Accounting Attribute-Value Pairs

The information sent to the RADIUS server is represented in the form of Attribute-Value (AV) pairs. These
AV pairs provide data for different applications. (For example, a billing application might require information
that is in the Acct-Input-Octets or the Acct-Output-Octets attributes of a RADIUS packet.)
AV pairs are automatically sent by a switch that is configured for 802.1x accounting. Three types of RADIUS
accounting packets are sent by a switch:
• START–sent when a new user session starts
• INTERIM–sent during an existing session for updates
• STOP–sent when a session terminates
You can view the AV pairs that are being sent by the switch by entering the debug radius accounting
privileged EXEC command. For more information about this command, see the Cisco IOS Debug Command
Reference, Release 12.4.
This table lists the AV pairs and when they are sent are sent by the switch.
