2.8 IGMP/IP Multicast

This function contains four options (Fig. 2.34.a), which are:

 IGMP/IP Multicast Table

 Static IP Multicast

 IGMP

 IGMP Statistics.

IGMP: Internet Group Management Protocol is used on IP networks to establish multicast

group memberships. It operates above the network layer of OSI. One of the most important

features related to this protocol is IGMP snooping, which is supported by EH7510 and

greatly strengthens network functionality.

IGMP Snooping: It is the process of “listening” to IGMP network traffic. By listening to

conversations between different devices, it maintains a map of which links need which IP

multicast streams. This means multicasts may be filtered from the links which do not need

them, and IGMP snooping allows a switch to only forward multicast traffic to the links that

have requested it.
