Configuring IGMP Snooping on EX Series Switches (J-Web Procedure)
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.
To enable IGMP snooping and configure individual options by using the J-Web interface:
To disable IGMP snooping on a VLAN, select the VLAN from the list and click Disable.
Field | Function | Your Action |
---|---|---|
VLAN Name | Specifies the VLAN on which to enable IGMP snooping. | Select a VLAN from the list to add it to the snooping configuration. |
Immediate Leave | Immediately removes a multicast group membership from an interface when it receives a leave message from that interface without waiting for any other IGMP messages to be exchanged (IGMP version 2 and IGMP version 3 only). | To enable the option, select the check box. To disable the option, clear the check box. |
Robust Count | Specifies the number of timeout intervals the switch waits before timing out a multicast group. | Type a value. |
Interfaces List | Statically configures an interface as a switching interface toward a multicast router or as a member of a multicast group. | Click one of the following options:
