3-15-3 Snooping


Function name:

Snooping

Function description:

IGMP snooping provide the switch to issue to prevent hosts on a local network
from receiving traffic for a multicast group they have not explicitly joined. It
provides switches with a mechanism to prune multicast traffic from links that
do not contain a multicast listener (IGMP client). A switch that does not IGMP
snoop will, by default, 'flood' multicast traffic to all the ports in a broadcast
domain (or t
he VLAN equivalent). Multicast can cause unnecessary or even
crippling load on host devices by requiring them to process packets they have
not solicited
