Syntax   igmp-show [group-ip ip-address] [node-ip ip-address][vlan vlan-id] [port port-number] [source ip-address] [node-type host|router|switch] [expires expires-number(s]]

group-ip ip-address

Specifies the multicast group IP address.

node-ip ip-address

Specifies the node IP address

vnet vnet-nam

Specifies the name of the VNET.

vlan vlan-id

Specifies the VLAN identifier.

port port-number

Specifies the port number.

source ip-address

Specifies the multicast source traffic.

node-type host|router|switch
