Usage Guidelines

Usage Scenario

If user hosts need to receive multicast data packets from a port for a long period of time, the igmp-snooping static-router-port command can be used to configure the port as a static router port.

Static router ports can be configured on different positions on a network to enable user hosts to regularly receive data for specific multicast groups or source-specific multicast groups.

Prerequisites

IGMP snooping has been configured globally.

Configuration Impact

A static router port does not age. To delete a static router port, you must run the undo igmp-snooping static-router-port command.

If the igmp-snooping static-router-port command is run more than once, all configurations take effect.

Example

# Configure a static router port.
