IGMP Configuration

Internet Group Management Protocol (IGMP) is an Internet protocol that provides a
way for an Internet computer to report its multicast group membership to adjacent
routers. It allows Compex CGX3224 to forward multicast traffic intelligently. The
switch "snoops" the IGMP query and report messages and forwards traffic to only the
ports that request the multicast traffic. This prevents the switch from broadcasting the
traffic to all ports and possibly affecting network performance.
Determines how often the switch broadcasts hello
messages to other switches.
Determines how long each of the listening and
learning states last before the interface begins
forwarding. This wait is necessary so that other
switches on the network ensure no loop is formed
before they allow the port to forward packets.
Determines the amount of time the switch stores
protocol information received on an interface.
