Displaying Multicast Group Information
When IGMP (Layer 3) is enabled on this switch the current multicast
groups learned via IGMP can be displayed in the IP/IGMP/Group
Information page. When IGMP (Layer 3) is disabled and IGMP (Layer 2)
is enabled, you can view the active multicast groups in the IGMP
Snooping/IP Multicast Registration Table (see page 3-198).
