Multicast Router Port Information - Planet SGSD-1022 User Manual

immediate leave should only be enabled on an interface if it is connected to only one IGMP-enabled device, either a service
host or a neighbor running IGMP snooping.
Immediate leave is only effective if IGMP snooping is enabled, and IGMPv2 or IGMPv3 snooping is used.
Immediate leave does not apply to a port if the Managed witch has learned that a multicast router is attached to it.
Immediate leave can improve bandwidth usage for a network which frequently experiences many IGMP host add and leave
requests.

4.9.1.3 Multicast Router Port Information

Multicast routers that are attached to ports on the Managed Switch use information obtained from IGMP, along with a multicast
routing protocol such as DVMRP or PIM, to support IP multicasting across the Internet. These routers may be dynamically
discovered by the switch or statically assigned to an interface on the switch.
You can use the Multicast Router Port Information page to display the ports on this Managed Switch attached to a neighboring
multicast router/switch for each VLAN ID.
