Parameter
vlan vlan-id: Specifies the VLAN the desired multicast group resides in.
ip-address: IP address of the desired multicast group.
Description
Use the display mpm group command to display the information about the IP
multicast groups or MAC multicast groups in a specified VLAN. If you do not specify the
vlan-id argument, this command displays the information about multicast groups in all
VLANs.
The information displayed contains the following fields:
z VLAN ID
z Router port
z IP multicast group
z IP multicast group address
z Member port of IP multicast group
z MAC multicast group
z MAC multicast group address
z Member port of MAC multicast group
Caution:
z The information displayed by this command includes that displayed by the display
igmp group command and port information.
z The information displayed by this command is the same as that displayed by the
display igmp-snooping group command except the VLAN properties. The
display igmp-snooping group command displays the information about the ports
that join Layer 2 multicast groups in VLANs that have the IGMP-snooping function
enabled. The display mpm group command displays the information about the
ports that join Layer 3 multicast groups in VLANs that have the IGMP function
enabled.
