DescriptionCommand
Displays IGMP snooping configuration by VLAN.
show ip igmp snooping [[vlan] vlan-id]
Displays IGMP snooping information about groups
by VLAN.
show ip igmp snooping groups [[vlan] vlan-id]
[detail]
Displays IGMP snooping queriers by VLAN.
show ip igmp snooping querier [[vlan] vlan-id]
Displays multicast router ports by VLAN.
show ip igmp snooping mrouter [[vlan] vlan-id]
Displays IGMP snooping explicit tracking information
by VLAN.
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.
However in a VPC peer, the EHT is also learned by cfs sync and is displayed by using the detail option.
Note
This example shows how to verify the IGMP snooping parameters:
switch# show ip igmp snooping
