Use this command to display information about multicast groups that MLD reported. The information is displayed only when MLD is enabled on at least one interface. If MLD was not enabled on even one interface, there is no group information to be displayed. The argument unit/slot/port corresponds to a physical routing interface or VLAN routing interface. The keyword vlan is used to specify the VLAN ID of the routing VLAN directly instead of in a unit/slot/port format.

| Group Compat Mode | The compatibility mode of the multicast group on this interface. The values it can take are MLDv1 and MLDv2. |
The following table is displayed to indicate all the sources associated with this group.
