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 3-175).
