Release Notes for Cisco Catalyst Blade Switch 3120 for HP, Cisco IOS Release 12.2(55)SE and Later

OL-22860-04

Resolved Caveats

• CSCti04980

After you upgrade the switch software to Cisco IOS Release 12.2(55)SE, enhanced auto-QoS

commands are generated when

–

auto-QoS is enabled on an interface

and

–

mls qos command is not enabled on the switch

If the mls qos command was already enabled on the switch, enhanced auto-QoS commands are

generated only when you configure one of these commands:

–

auto qos classify [police]

–

auto qos trust {cos | dscp}

–

auto qos video {cts | ip-camera}

Cisco IOS Release 12.2(55)SE supports implicit and explicit migration to enhanced auto-QoS

configurations.

Implicit migration to enhanced auto-QoS occurs on a switch running legacy auto-QoS when you

configure the auto qos video, auto qos trust, or auto qos classify command on an interface. Global

and interface configurations on the switch migrate to the enhanced video or trust auto-QoS

configurations.

Explicit migration to enhanced auto-QoS occurs on a switch when you enable the auto qos srnd4

global configuration command. You can configure the [no] form of this commandafter you remove

auto-QoS functionality from all switch interfaces.

When you disconnect the spanning tree protocol (STP) peer link, the STP port path cost

configuration changes.

There is no workaround.

If a static MAC address entry is configured for an IP address in the global routing table, ping

requests are sent through the global context, and replies are sent through Virtual Routing and

Forwarding (VRF). This is a VRF leak.

The workaround is to remove the static MAC address entry.
