Release Notes for Cisco Catalyst Blade Switch 3120 for HP, Cisco IOS Release 12.2(52)SE
OL-19714-01
Resolved Caveats
• 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.
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.
• CSCsw69015
When you enter the mvr vlan vlan-id global configuration command to create an MVR VLAN and
enable MVR on the switch by entering the mvr global configuration command, if you enter the show
mvr interface interface-id members privileged EXEC command, the output shows the MVR
groups on the interface. However, if you enable MVR first and then create the MVR VLAN, the
MVR groups are not displayed correctly.
• CSCsw69335
In a stacked environment, IP ACLs are not applied to interfaces on member switches unless IP
routing is enabled.
The workaround when applying IP ACLs to stack member interfaces is to enable IP routing on the
stack master by entering the ip routing global configuration command.
• CSCsw72527
When a switch sends an ARP request to find the MAC address of the default gateway, the switch
sends the request in the wrong VLAN. An ARP entry associating the MAC address with the wrong
VLAN is added to the table.
The workaround is to use the no arp arpa global configuration command in all VLANs with IDs
lower than the ID of the correct VLAN.
• CSCsw96933
A switch running Cisco IOS Release 12.2(46)SE might lose packets for up to 30 seconds when a
link fails. This occurs in some multiple spanning-tree (MST) topologies.
There is no workaround.
• CSCsx71632
When VLAN-based quality of service (QoS) is enabled and then disabled on an interface by entering
the mls qos vlan-based interface configuration command followed by the no version of the
command, the port policy is not applied properly and could result in undefined behavior for packets
matching the port policy.
The workaround is to remove the port policy by entering the no service-policy input
policy-map-name interface configuration command and then reapply it to the interface.
• CSCsx78068
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.
– Disable and then reenable native VLAN tagging by entering the no vlan dot1q tag native
global configuration command followed by the vlan dot1q tag native command.
