When a community string is assigned by the cluster command switch, you cannot get any
dot1dBridge MIB objects by using a community string with a VLAN entity from a cluster member
switch.
dot1dBridge MIB objects by using a community string with a VLAN entity from a cluster member
switch.
The workaround is to manually add the cluster community string with the VLAN entity on the
member switches for all active VLANs shown in the show spanning-tree summary display. This
is an example of such a change, where cluster member 3 has spanning tree on vlan 1-3, and the
cluster commander community string is public@es3.

CSCsw68528
On switches running Cisco IOS Release 12.2(44)SE or 12.2(46)SE, when you enter the show mvr
interface interface-id members privileged EXEC command to see status of an MVR port, an MVR
member port that is not connected always shows as ACTIVE.

member port that is not connected always shows as ACTIVE.
The workaround is to use the show mvr interface interface-id or the show mvr members privileged
EXEC command. These command outputs show the correct status of an MVR port.

If you enable 802.1Q native VLAN tagging by entering the vlan dot1q tag native global
configuration command and then change the native VLAN ID on an ingress trunk port by entering
the switchport trunk native vlan vlan-id interface command, untagged traffic is forwarded instead
of being dropped.

The workaround is to use one of these methods:
–
Enter a shutdown followed by a no shutdown interface configuration command on the trunk
port.
