  • Page 61: Igmp Snooping

    IP multicast packets are running over the network. This is because a switch that does not support IGMP or IGMP Snooping can not tell the multicast packet from the broadcast packet, so it can only treat them all as the broadcast packet.

  • Page 62: Allowed Group

    The allowed group function can limit the IGMP multicast group registration behavior on the switch. You can set some specific allowed IP multicast groups. If the switch received an IGMP report, but the IP multicast address is not included in the allowed IP multicast groups list, the switch will not do IGMP registration for this received IGMP report.
