7.4.2A Note about IGMP Snooping

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1sender to 1 recipient) or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to just a group of hosts on the network. IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to establish membership in a Multicast group - it is not used to carry user data. Refer to RFC 2236 for information IGMP version 2 and RFC 1112 for IGMP version 1. A Layer 2 switch can passively snoop on IGMP Query and Report packets transferred between IP Multicast Routers/Switches and IP Multicast host groups to learn the IP Multicast group members. It checks IGMP packets passing through it, picks out the group registration information, and configures multicasting accordingly. IGMP Snooping generates no additional network traffic, allowing you to significantly reduce the multicast traffic passing through your switch.

7.4.3Mfilter Command

Syntax:

192.168.1.1 bridge> mfilter

This command displays the multicast filtering database. The mfilter command is what allows you to monitor the AES-100’s IGMP snooping activities.

The following is an example of a multicast filtering database.

192.168.1.1 bridge> mfilter
