Usage Guidelines

Usage Scenario

By default, SSM group addresses range from 232.0.0.0 to 232.255.255.255. If SSM group addresses beyond this range are configured using the ssm-policy command and static SSM mapping rules are configured using the ssm-mapping command, run the display igmp ssm-mapping command to display SSM mappings and check whether SSM mapping is enabled on an interface.

Example

The actual command output varies according to the device. The command output here is only an example.
