Release Notes for the Catalyst 3750 Switch Cisco IOS Release 12.1(14)EA1

OL-4215-01

Open Caveats

–

The port learns the MAC address of multiple hosts.

–

VLAN assignment is not enabled for the authorized host.

The workaround is to disable and then re-enable port security on the port.

If a switch stack is running fallback bridging and the switches in the switch stack have routed ports

in the bridge-group, fallback bridging might not work. This occurs when the TCAM is full and a

switch is added or deleted from the switch stack.

The workaround is to stop traffic to free up space in TCAM and then to reload the whole switch

stack. Then enable the traffic 1 minute after the switch stack comes back up.

If a Catalyst 3750 switch loaded with Cisco IOS Release 12.1(14)EA1 software is added to a switch

stack running Cisco IOS Release 12.1(11)AX software, the stack member changes to version

mismatch (as expected). If an SNMP application traverses the CISCO-FLASH-MIB, a stack

member in version mismatch state can fail.

The workaround is to avoid traversing the CISCO-FLASH-MIB while the switch stack is being

upgraded from Cisco IOS Release 12.1(11)AX to Cisco IOS Release 12.1(14)EA1.

A Catalyst 3750 switch does not work with the User Registration Tool (URT). The PC attempting

to connect to the network can log in successfully, but is not allowed to pass traffic after the port is

moved to the user VLAN. The MAC address for that device shows BLOCKED.

There is no workaround.

• CSCeb42953

If an IP phone is connected to a port on the stack master, and 802.1X port security and voice VLAN

are configured on the port, disabling port security causes the IP phone MAC address to be deleted

from the MAC address table on all stack members. The MAC address table on the stack master

retains the phone MAC address.

There is no workaround.

If an interface on a Catalyst 3750 switch is mapped to queue-set 2, and you disable and then

re-enable multilayer QoS globally using the mls qos global configuration command, the interface is

no longer mapped to the correct egress queue-set.

The workaround is to reconfigure the interface queue-set by using the no queue-set interface

configuration command followed by the queue-set 2 interface configuration command.

• CSCeb56226

If an 802.1X port is configured for forced-unauthorized port control mode and voice VLAN, after

you remove the voice VLAN and disable 802.1X on the port, the port no longer passes traffic.

The workaround is to restart the port by using the shutdown and then the no shutdown interface

configuration commands.
