Description (partial)


If you have a port-channel setup as an access-port and remove the port-channel interface, the Configuration "ip igmp snooping querier" will be removed from the corresponding SVI interface.

For example:

If SVI 301 on a 6500 is configured with "ip igmp snooping querier" and port-channel 1 is configured to be an access port in vlan 301.  When port-channel 1 and its corresponding physical interfaces are removed, the "ip igmp snooping querier" command will be removed from SVI 301.


Need to have a port-channel setup as an access port and the corresponding SVI.  

Effects all SXH versions and SXI prior to 12.2(33)SXI2.
