IGMP Snooping

IGMP Configuration

This switch can use Internet Group Management Protocol (IGMP) to filter multicast
traffic. IGMP Snooping can be used to passively monitor or "snoop" on exchanges
between attached hosts and an IGMP-enabled device, most commonly a multicast
router. In this way, the switch can discover the ports that want to join a multicast
group, and set its filters accordingly.
This chapter describes the following topics:
IGMP Snooping — Enables IGMP Snooping on the switch.

Router Port — Configures ports that are attached to a multicast router/switch.

Group Address — Statically assigns a multicast service to a port on the switch.

Use the IGMP > IGMP Snooping page to enable the switch to forward multicast
traffic efficiently to the attached network.
Usage Guidelines
Based on the IGMP query and report messages, the switch forwards multicast

traffic only to the ports that request it. This prevents the switch from
broadcasting the traffic to all ports and possibly disrupting network
performance.
This switch can passively snoop on IGMP Query and Report packets transferred

between IP multicast routers/switches and IP multicast host groups to identify
the IP multicast group members. The switch simply monitors the IGMP packets
passing through it, picks out the group registration information, and configures
the multicast filters accordingly.
IGMP can be enabled on up to 2 VLANs simultaneously.

Parameters
These parameters are displayed:
IGMP Snooping Setting — When enabled, the switch will monitor network

traffic to determine which hosts want to receive multicast traffic. This is referred
to as IGMP Snooping. (Default: Disabled)
