Usage Guidelines
Usage Scenario
MLD snooping creates and maintains a Layer 2 multicast forwarding table by listening on MLD messages exchanged between hosts and a Layer 3 device. The display mld-snooping port-info command shows member ports in the Layer 2 multicast forwarding table. According to the command output, you can know which downlink interfaces have multicast users connected, and control multicast services conveniently.
Precautions
This command can display member 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.
