VLAN Configuration

Use the IGMP Snooping Querier VLAN Configuration page to enable the snooping querier feature on one or more VLANs and to configure per-VLAN IGMP (Internet Group Management Protocol) snooping querier settings. Only VLANs that have the IGMP snooping querier feature enabled appear in the table.

To access this page, click Switching > IGMP Snooping Querier > VLAN Configuration in the navigation menu.

Use the buttons to perform the following tasks:

To enable the IGMP snooping querier feature on a VLAN, click Add and specify the desired settings.
To change the IGMP snooping querier settings for a VLAN, select the entry to modify and click Edit.
To disable the IGMP snooping querier feature on one or more VLANs, select each entry to change and click Remove. You must confirm the action before the entry is deleted. Clicking this button does not remove the VLAN from the system.

IGMP Snooping Querier VLAN Configuration Fields

Field	Description
VLAN ID	The VLAN on which the IGMP snooping querier is enabled. When enabling the IGMP snooping querier on a VLAN, use this menu to select the desired VLAN. Only VLANs that have been configured on the system and are not already enabled for the IGMP snooping querier appear in the menu. When modifying IGMP snooping querier settings, this field identifies the VLAN that is being configured.
Querier Election Participation	The participation mode for the IGMP snooping querier election process: Enabled – The IGMP snooping querier on this VLAN participates in the querier election process when it discovers the presence of another querier in the VLAN. If the snooping querier finds that the other querier source IP address is lower than its own address, it stops sending periodic queries. If the snooping querier wins the election (because it has the lowest IP address), then it continues sending periodic queries. Disabled – When the IGMP snooping querier on this VLAN sees other queriers of the same version in the VLAN, the snooping querier moves to the non-querier state and stops sending periodic queries.
Querier VLAN IP Address	The IGMP snooping querier address the VLAN uses as the source IP address in periodic IGMP queries sent on the VLAN. If this value is not configured, the VLAN uses the global IGMP snooping querier IP address.
