Cisco Catalyst 2960-X User Manual

You can use this feature in IP phone deployments where a PC is connected to the IP phone. A security violation
found on the data VLAN results in the shutdown of only the data VLAN. The traffic on the voice VLAN
flows through the switch without interruption.

Common Session ID
Authentication manager uses a single session ID (referred to as a common session ID) for a client no matter
which authentication method is used. This ID is used for all reporting purposes, such as the show commands
and MIBs. The session ID appears with all per-session syslog messages.
The session ID includes:
•
The IP address of the Network Access Device (NAD)
•
A monotonically increasing unique 32 bit integer
•
The session start time stamp (a 32 bit integer)
This example shows how the session ID appears in the output of the show authentication command. The
session ID in this example is 160000050000000B288508E5:
Switch# show authentication sessions

This is an example of how the session ID appears in the syslog output. The session ID in this example is
also160000050000000B288508E5:
1w0d: %AUTHMGR-5-START: Starting 'mab' for client (0000.0000.0203) on Interface Fa4/0/4

1w0d: %AUTHMGR-7-RESULT: Authentication result 'success' from 'mab' for client
(0000.0000.0203) on Interface Fa4/0/4 AuditSessionID 160000050000000B288508E5
The session ID is used by the NAD, the AAA server, and other report-analyzing applications to identify the
client. The ID appears automatically. No configuration is required.
