239.255.255.255. If you do not specify a multicast group, this command displays information about
all multicast groups.
interface interface-type interface-number: Specifies an interface by its type and number. If you do
not specify an interface, this command displays multicast group information for all interfaces.

Usage guidelines
For the VXLAN multicast source interface of a multicast-mode VXLAN to join its VXLAN multicast
group, you must enable the IGMP host feature on the interface. The VXLAN multicast source
interface provides the source IP address for multicast VXLAN packets.
Use this command to verify the following information:
•
Multicast group information for VXLANs.
•
Group membership status of VXLAN multicast source interfaces.
