Release Notes for Cisco Catalyst Blade Switch 3120 for HP, Cisco IOS Release 12.2(50)SE and Later

OL-18270-03

Open Caveats

• CSCsg67684

When a cross-stack LACP EtherChannel has a maximum configuration, such as eight active and

eight hot-standby ports, and there are multiple rapid sequential master failovers and stack rejoins

that cause extreme stress, the port channel might not function as expected. Some ports might not join

the EtherChannel, and traffic might be lost. You can detect the condition by using the remote

command all show etherchannel summary privileged EXEC command.

There is no workaround. The out-of-sync switches must be reloaded.

• CSCsi06399

When a RIP network and IP address are configured on an interface, a traceback error occurs after

you enter the shutdown, no shutdown, switchport, and no switchport interface configuration

commands.

The workaround is to configure the RIP network and the IP address after you configure the interface.

• CSCsi14303

When booting a switch stack configured for IP source guard with port security and dynamic ARP

inspection, a message similar to this might appear:

SYS-2-LINKED: Bad enqueue of 2A3DE74 in queue 22881BC (l3a3-9) -Process=

"Port-Security", ipl= 6, pid= 161 (l3a3-9) -Traceback= 119CC50 11D2264 9571E0 119B4E0

95D41C 80DBD8 80E734 80B998 80AAD4 80B55C 9EB158 9E2544 (l3a3-9)

There is no workaround. This message is only information; switch functionality is not affected.

• CSCsi26444

The error message

%DOT1X_SWITCH-5-ERR_VLAN_NOT_FOUND might appear for a switch stack under

these conditions:

–

IEEE 802.1 is enabled.

–

A supplicant is authenticated on at least one port.

–

A new member joins a switch stack.

You can use one of these workarounds:

–

Enter the shutdown and the no shutdown interface configuration commands to reset the port.

–

Remove and reconfigure the VLAN.

• CSCsi52914

When you are configuring a SPAN session, this message might erroneously appear even when two

source sessions are not configured:

% Platform can support a maximum of 2 source sessions

The workaround is to reboot the switch stack.

• CSCsi65551

In certain situations during master switch failover, a VLAN that has been error disabled on a port

might be re-enabled after the master switch failover, even though the port has not been configured

for automatic recovery.

There is no workaround.
