X Accounting Attribute-Value Pairs - Cisco 3032 Software Configuration Manual

Chapter 9 Configuring IEEE 802.1x Port-Based Authentication

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:

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
