The display igmp ssm-mapping command displays SSM mapping information and whether IGMP SSM mapping is configured on a specific interface.
display igmp [ vpn-instance vpn-instance-name | all-instance ] ssm-mapping { group [ group-address ] | interface [ interface-type interface-number ] }
| Parameter | Description | Value |
|---|---|---|
| vpn-instance vpn-instance-name | Specifies a VPN instance. vpn-instance-name specifies the name of the VPN instance. | The name is a string of 1 to 31 characters. |
| all-instance | Indicates all the instances. | - |
| group group-address | Displays the SSM mapping entry to which a specified group corresponds on the FW. group-address specifies the group address in dotted decimal notation. |
The address is in dotted decimal notation.The value ranges from 224.0.0.0 to 239.255.255.255. |
| interface interface-type interface-number | Displays whether a specified interface is enabled with IGMP SSM mapping. |
- |
By default, the SSM group address ranges from 232.0.0.0 to 232.255.255.255. You can specify the SSM group addresses that fall outside this range with the ssm-policy command, and configure static SSM mapping rules with the ssm-mapping command.
When the display igmp ssm-mapping command is used, the following situations occur:
If neither vpn-instance nor all-instance is not specified, only the public network instance is displayed.
If group-address is specified, only the SSM mapping entry to which the group corresponds is displayed.
If interface interface-type interface-number is specified, only whether the interface is enabled with SSM mapping is displayed. If the interface is not enabled with IGMP SSM mapping or the status of the interface is Down, the failure prompt is displayed.
