Cisco Cisco IOS Software Release 12.2(53)SE

CSCtd72456

After you have entered the snmp-server host informs global configuration command to enable 
SNMP informs on a switch, the switch might fail if you enter the show snmp pending user EXEC 
command.

There is no workaround. Do not enter the show command when SNMP informs are enabled. 

This section was added to the “Configuring IP Unicast Routing” chapter:

To configure VRF-Aware RADIUS, you must first enable AAA on a RADIUS server. This 
release supports the ip vrf forwarding vrf-name server-group configuration and the ip radius 
source-interface global configuration commands, as described in the Per VRF AAA Feature 
Guide at this URL:

This section was added to the “Configuring IEEE 802.1x Port-Based Authentication” chapter: 

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

Interface  MAC Address     Method   Domain   Status         Session ID
