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 the VLAN equivalent). Multicast can cause unnecessary or even
crippling load on host devices by requiring them to process packets they have
not solicited
