Usage Guidelines

Usage Scenario

A router port connects the switch to an upstream Layer 3 multicast device. The router port can be statically configured or dynamically generated after the interface receives an IGMP Query message or a PIM Hello message.

You can run the display igmp-snooping router-port command to view the type, name, lifetime, and aging time of a router port.

Precautions

This command can display information about router ports in a VLAN only when IGMP snooping has been enabled in the VLAN using the igmp-snooping enable (VLAN view) command, and at least one interface in the VLAN is in Up state.

Example

# Display information about router ports in VLAN 2.

<HUAWEI> display igmp-snooping router-port vlan 2
