Cisco Catalyst 2960-X User Manual

If you configure the authentication violation interface configuration command with the replace keyword,
the authentication process on a port in multi-domain mode is:
•
A new MAC address is received on a port with an existing authenticated MAC address.
•
The authentication manager replaces the MAC address of the current data host on the port with the new
MAC address.
•
The authentication manager initiates the authentication process for the new MAC address.
•
If the authentication manager determines that the new host is a voice host, the original voice host is
removed.
If a port is in open authentication mode, any new MAC address is immediately added to the MAC address
table.
802.1x Accounting
The 802.1x standard defines how users are authorized and authenticated for network access but does not keep
track of network usage. 802.1x accounting is disabled by default. You can enable 802.1x accounting to monitor
this activity on 802.1x-enabled ports:
•
User successfully authenticates.
•
User logs off.
•
Link-down occurs.
•
Re-authentication successfully occurs.
•
Re-authentication fails.
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.
