Release Notes for Cisco Catalyst Blade Switch 3120 for HP, Cisco IOS Release 12.2(55)SE and Later

OL-22860-04

Resolved Caveats

• CSCtf19991

If the RADIUS authentication server is unavailable and inaccessible authentication bypass is

enabled, the switch grants the client access to the network by putting the connected port in the

critical-authentication state in the RADIUS-configured or the user-specified access VLAN. After

the server is available, the client is not reinitialized and moved out of the critical VLAN.

There is no workaround.

• CSCtf33948

A PC in 802.1x or multidomain authentication (MDA) mode is connected to an IP phone and

connected to a MDA-enabled switch port. After the PC and phone are authenticated on the port, the

PC is down. The port does not automatically reauthenticate the PC.

There is no workaround.

• CSCtf78276

A switch running Cisco IOS Release 12.2(53)SE1 stops when IEEE 802.1x authentication is

enabled.

The workaround is to apply a VLAN that the RADIUS server assigned to the switch.

• CSCtg26941

Multidomain authentication (MDA) with guest VLAN or MAC authentication bypass (MAB) as a

fallback method is enabled on a switch running Cisco IOS Release 12.2(53)SE. When a non-802.1x

client is connected to a IP phone and the phone connected to a switch port shuts down and then

restarts, the client MAC address status is drop in the MAC address table. It takes 5 minutes for the

client to access the network.

The workaround is to use another software release, such as Cisco IOS Release 12.2(44)SE2.

• CSCtg47738

This error message is displayed after copying a configuration file to the running configuration file

fails:

%Error opening system:/running-config (No such file or directory)

The output of the dir system:/ EXEC command also does not show a running configuration file.

The workaround is to reload the switch.

• CSCth18118

When VTP pruning is enabled in a VTP domain, the switch in VTP server mode sends

advertisements to neighboring switches. If the VTP and VLAN configuration for neighboring ports

is not updated, VLANs on those ports can be pruned, causing a network traffic outage.

The workaround is to disable VTP pruning.

• CSCth88306

This message appears after inserting the CVR-X2-SFP converter module and the X2-10GB-SR

transceiver modules in the10-Gigabit slots of the Catalyst 3750-E and 3560-E switches:

%GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port Te1/0/1 has bad crc

There is no workaround.
