IGMP snooping regulates multicast traffic in a switched network. With IGMP snooping
enabled, a LAN switch monitors the IGMP transmissions between a host (a network
device) and a multicast router, keeping track of the multicast groups and associated
member ports. The switch uses that information to make intelligent multicast-forwarding
decisions and forward traffic to the intended destination interfaces.
Configure IGMP snooping on one or more VLANs to allow the switch to examine IGMP
packets and make forwarding decisions based on packet content. By default, IGMP
snooping is enabled on J-EX Series switches.
This example describes how to configure IGMP snooping:
Requirements on page 2055
Overview and Topology on page 2056
Configuration on page 2056
This example uses the following software and hardware components:
One J-EX4200-24T switch
Before you configure IGMP snooping, be sure you have:
Configured the
employee-vlan
Assigned interfaces ge-0/0/1
