IGMP

With Internet Group Management Protocol (IGMP) Snooping, you can
configure the switch to forward multicast traffic intelligently. Based on the
IGMP query and report messages, the switch forwards traffic only to the
ports that request multicast traffic. This prevents the switch from
broadcasting the traffic to all ports and possibly disrupting network
performance.
The IGMP option can be set as follows:
Enabled — The system detects IGMP queries and report packets and
•
manages IP multicast traffic through the switch.
• Disabled — The switch forwards traffic and ignores any IGMP
requests.
NOTE: IGMP requires a
router that learns about
the presence of multicast
groups on its subnets and
keeps track of group
membership.
