Configuring basic IGMP snooping functions

Before you configure basic IGMP snooping functions, complete the following tasks:

• Configure the corresponding VLANs.

• Determine the IGMP snooping version.

• Determine the IGMP last-member query interval.

• Determine the maximum response delay for IGMP general queries.

Enabling IGMP snooping

When you enable IGMP snooping, follow these guidelines:

• You must enable IGMP snooping globally before you enable it for a VLAN.

• IGMP snooping for a VLAN works only on the member ports in that VLAN.

You can enable IGMP snooping for a VLAN in IGMP-snooping view, or for a VLAN in VLAN view. These

configurations have the same priority level.

To enable IGMP snooping for a VLAN in IGMP-snooping view:
