I NFORMATION
When IGMP (Layer 3) is enabled on the switch, use the Multicast > IGMP >
Group Information pages to display the current multicast groups learned
through IGMP. When IGMP (Layer 3) is disabled and IGMP (Layer 2) is
enabled, the active multicast groups can be viewed on the Multicast >
IGMP Snooping > Forwarding Entry page (see page 528 ).
C OMMAND U SAGE
To display information about multicast groups, IGMP must first be enabled
on the interface to which a group has been assigned (see "Configuring
IGMP Interface Parameters" on page 550 ), and multicast routing must be
enabled globally on the system (see "Configuring Global Settings for
Multicast Routing" on page 708 ).
