Usage Guidelines

Usage Scenario

A router port is a switch port connected to an upstream Layer 3 multicast device. Router ports can be statically configured or dynamically created after receiving an MLD Query message or a PIM Hello message. A router port receives multicast data packets from the upstream multicast device and forwards the packets to group member ports.

The display mld-snooping router-port command displays information about router ports, including the type, name, age, and aging time of each router port.

Precautions

This command can display router port information only when MLD snooping is enabled globally and in a VLAN using the mld-snooping enable command and the VLAN is in Up state.
