When a stack is started in per-VLAN Spanning Tree plus (PVST+) or Rapid-PVST+ mode with
more than 128 VLANs, the spanning-tree instance created for the specified VLAN now includes
ports on the member switches when these steps are followed:
more than 128 VLANs, the spanning-tree instance created for the specified VLAN now includes

a.
The spanning-tree vlan vlan-id global configuration command is entered for the 129th VLAN. As
expected, no STP instance is created.

b.
One or more of the existing spanning-tree instances is deleted.
c.
The spanning-tree vlan vlan-id global configuration command is entered for the same VLAN (as
in step 1 above). As expected, an STP instance is now created. But this instance does not include
ports on the member switches.

The IGMP maximum query response time is no longer set to 1 second. You can configure this value
by using the ip igmp query-max-response-time seconds interface configuration command.

CSCed33857
A switch stack now forwards frames over an EtherChannel when the physical links of the EtherChannel
are on a member switch. In previous releases, the stack did not forward frames when the EtherChannel
was configured as a trunk and the stack was running IEEE 802.1S Multiple STP (MSTP) mode.

Cisco CMS Caveats Resolved in Cisco IOS Release 12.2(18)SE
These CMS caveats were resolved in Cisco IOS Release 12.1(20)EA1:

CMS now recognizes 802.1t spanning-tree extensions and port-priority configuration values under
the STP Port Parameters tab, and they are now validated before they are added to the switch.

are added to the switch.

Shaped bandwidth weights are invalid if either the sum of their reciprocals is greater than one, or if
the sum of their reciprocals is equal to one and the shaped weight of the queue is zero. CMS now
detects these invalid bandwidth weights.
