bridge is the designated bridge and which
interface is the designated interface.
3. Specify the interface priority to determine
which interface is elected as the root port.
4. If you want to disable the interface, select
the check box.

Configuring IGMP Snooping (J-Web Procedure)
NOTE: This topic applies only to the J-Web Application package.
IGMP snooping regulates multicast traffic in a switched network. With IGMP snooping
enabled, the EX Series switch monitors the IGMP transmissions between a host (a network
device) and a multicast router, keeping track of the multicast groups and associated
member interfaces. The switch uses that information to make intelligent
multicast-forwarding decisions and forward traffic to the intended destination interfaces.
You can 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 EX Series switches.
