Configuring IGMP Snooping
Command
show ip igmp snooping [[vlan] vlan-id]
show ip igmp snooping groups [[vlan] vlan-id]
[detail]
show ip igmp snooping querier [[vlan] vlan-id]
show ip igmp snooping mrouter [[vlan] vlan-id]
show ip igmp snooping explicit-tracking vlan
vlan-id
VPC behavior for v2 EHT: In a VPC scenario, the explicit host tracking is not synced to the VPC peer.
Note
However in a VPC peer, the EHT is also learned by cfs sync and is displayed by using the detail option.
This example shows how to verify the IGMP snooping parameters:
switch# show ip igmp snooping
