Usage Guidelines

You can run this command to view multicast sources mapped to a multicast group. SSM mapping entries can be configured using the ssm-mapping (MLD view) command. The display mld ssm-mapping command also allows you to view the SSM mapping status on an interface, which can be configured using the mld ssm-mapping enable command.
