IGMP SNOOPING 

15.1 

General 

Snooping is the process of listening to IGMP (Internet Group Management Protocol) network traffic to 
control delivery of IP multicast packets. Network switches supporting IGMP snooping listen to IGMP 
conversation between hosts and routers and maintain a map of the ports that the IP multicast traffic 
should go through, while filter the IP multicast traffic from other Switch ports which do not need those IP 
Multicast packets, conserving bandwidth on those links.

IGMP Snooping – Configuration – Global Settings 

 

Figure 15-1: IGMP Global Settings

 

15.2.1 

IGMP Snooping Configuration 

•

 

Enable IGMP Snooping

 - Enable the Global IGMP Snooping. 

•

 

Unregistered IPMCv4 Flooding Enabled

 - Enable unregistered IPMCv4 traffic flooding. The 

flooding control takes effect only when IGMP Snooping is enabled. When IGMP Snooping is 
disabled, unregistered IPMCv4 traffic flooding is always active despite this setting. 

•

 

IGMP SSM Range

 - SSM (Source-Specific Multicast) Range allows the SSM-aware hosts and 

routers run the SSM service model for the groups in the address range. Assign valid IPv4 
multicast address as prefix with a prefix length (from 4 to 32) for the range. 

•

 

Leave Proxy Enabled

 - Enable IGMP Leave Proxy. This feature can be used to avoid 

forwarding unnecessary leave messages to the router side.  

•

 

Proxy Enabled 

-

 

Enable IGMP Proxy. This feature can be used to avoid forwarding 

unnecessary join and leave messages to the router side.
