Release Notes for Cisco Catalyst Blade Switch 3120 for HP, Cisco IOS Release 12.2(55)SE and Later
OL-22860-04
Resolved Caveats
• CSCtl60151
The switch sometimes reloads after a CPU overload, regardless of the process that is overloading
the CPU.
This problem has been corrected.
• CSCtn11259
If a switch stack is configured with the stack-mac persistent timer value interface configuration
command, the switch virtual interface (SVI) should remain in shutdown mode during a switchover.
In this case, the SVI is in up mode.
The workaround is to specify the timer value to be long enough so that the stack's MAC address is
not changed.
• CSCto67688
If a member switch does not have an access control list (ACL) and is running an Enforcement Policy
Module (EPM) session, the client on that interface is re-authorized each time that the switch reloads.
The workaround is to configure an ACL on the interface.
• CSCtr79386
The switch fails when DHCP snooping is configured and packet data traffic is excessive. The traffic
exhausts the I/O memory and triggers the switch to crash.
There is no workaround.
Caveats Resolved in Cisco IOS Release 12.2(55)SE3
• CSCtg71149
When ports in an EtherChannel are linking up, the message
EC-5-CANNOT_BUNDLE2 might appear.
This condition is often self-correcting, indicated by the appearance of
EC-5-COMPATIBLE message
following the first message. On occasion, the issue does not self-correct, and the ports may remain
unbundled.
The workaround is to reload the switch or to restore the EtherChannel bundle by shutting down and
then enabling the member ports and the EtherChannel in this order:
– Enter the shutdown interface configuration command on each member port.
– Enter the shutdown command on the port-channel interface.
– Enter the no shutdown command on each member port.
– Enter the no shutdown command on the port-channel interface.
• CSCtn18139
When the show spanning-tree vlan VLAN interface fastethernet 0 command is entered, the switch
restarts.
The FastEthernet 0 interface is a management interface that does not run Spanning Tree Protocol
(STP). Do not run show spanning-tree commands for management interfaces.
• CSCto55124
When a member switch port security is used with port-based dot1x authentication and the switch
MAC address is sticky, a connected device authenticates itself. Its MAC address is added as sticky
in the switch configuration and in the port security tables of the stack switches. When the switch is
