Configuring static ports
You can configure a port as a static port for the following purposes:
• To make all the hosts attached to the port receive multicast data for a multicast group, configure the
port as a static member port for the multicast group.
• To make the Layer 2 device attached to the port forward all received multicast traffic on the port,
configure the port as a static router port.
You can also configure a port as a static router port, through which the switch can forward all the
multicast traffic it receives.
When you configure static ports, follow these guidelines:
• A static member port does not respond to queries from the IGMP querier. When you configure a
port as a static member port or cancel this configuration on the port, the port does not send
unsolicited IGMP reports or IGMP leave messages.
• Static member ports and static router ports never age out. To remove such a port, use the undo
igmp-snooping static-router-port or the undo igmp-snooping static-group command.

3. Configure the port as a static

By default, a port is not a static

By default, a port is not a static
router port.
Enabling IGMP snooping fast-leave processing
The IGMP snooping fast-leave processing feature enables the switch to process IGMP leave messages
quickly. With this feature enabled, when the Layer 2 device receives an IGMP leave message on a port,
