# Configuring IGMP snoop, proxy, and static mrouter ports on a VLAN

Use the following procedure to configure IGMP snooping, proxy, and static mrouter ports on a VLAN.

By default, IGMP snoop and proxy are disabled, and no static mrouter ports are configured.

## Procedure steps

1. From the navigation tree, double-click IP Routing.

2. In the IP Routing tree, double-click IGMP

3. In the work area, click the Snoop tab.

4. In the table, double-click the cell under the SnoopEnable column heading.

5. Select true from the drop-down list to enable IGMP snoop.

6. In the table, double-click the cell under the ProxySnoopEnable column heading.

7. Select true from the drop-down list to enable IGMP proxy.

8. In the table, double-click the cell under the SnoopMRouterPorts column heading.

9. Select the desired ports from the list to configure mrouter ports.

10. In the toolbar, click Apply.

## Variable definitions

The following table describes the fields of the Snoop tab.

Field | Description
--- | ---
IfIndex | Specifies the VLAN ID.
SnoopEnable | Specifies the IGMP snoop status: enabled (true) or disabled (false).
ProxySnoopEnable | Specifies the IGMP proxy status: enabled (true) or disabled (false).
SnoopMRouterPorts | Specifies the static mrouter ports. Such ports directly attach to a multicast router so the multicast data and group reports are forwarded to the router.
SnoopActiveMRouterPorts | Displays all dynamic (querier port) and static mrouter ports that are active on the interface.
SnoopMRouterExpiration | Specifies the time remaining before the multicast router ages out on this interface. If the switch does not receive queries before this time expires, it flushes out all group memberships known to the VLAN. The Query Max Response Interval (obtained from the queries received) is the timer resolution.
