VLAN Status

Use the VLAN Status page to enable or disable MLD snooping on system VLANs and to view and configure per-VLAN MLD snooping settings. Only VLANs that are enabled for MLD snooping appear in the table.

To access this page, click Switching > MLD Snooping > VLAN Status in the navigation menu.

Use the buttons to perform the following tasks:

To enable MLD snooping on a VLAN, click Add and configure the settings in the available fields.
To change the MLD snooping settings for an MLD-snooping enabled VLAN, select the entry with the settings to change and click Edit.
To disable MLD snooping on one or more VLANs, select each VLAN to modify and click Remove. You must confirm the action before MLD snooping is disabled on the selected VLANs. When MLD snooping is disabled, the VLAN entry is removed from the table, but the VLAN itself still exists on the system.

Max Response Time	The number of seconds the VLAN should wait after sending a query if does not receive a report for a particular group. The specified value should be less than the Group Membership Interval.
