Configuring static ports
If all hosts attached to a port are interested in the multicast data addressed to a particular multicast group
or the multicast data that a particular multicast source sends to a particular group, you can configure the
port as a static member port for the specified multicast group or the specified multicast source and group.
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
corresponding undo command.
To configure static ports:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
interface interface-type
interface-number
N/A
3. Configure the port as a static
member port.

By default, a port is not a static
member port.
