Cisco Cisco IOS Software Release 12.2(52)SE

CSCtb33780

The link between a switch with a 100BaseFX-FE small form-factor pluggable (SFP) module and a 
connected device remains up when one of the fiber cables is removed.

The workaround is the use UniDirectional Link Detection (UDLD) in aggressive mode

CSCtb77378

When you use IEEE 802.1x authentication with web authentication and an HTTP page opens, the 
switch redirects the user to an HTTP login page, not a HTTPS login page. 

The workaround is to remove the custom banner.

CSCtb97439

When remote neighbors change, the LLDP MIB does not properly update the remote neighbors.

The workaround is to clear the LLDP table by entering the clear lldp table privileged EXEC 
command. 

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
