Function
The display multicast-domain vpn-instance switch-group send command displays the Switch-Group information sent by a specified VPN instance in a multicast domain (MD).
Parameters
| Parameter | Description | Value |
|---|---|---|
| group groupAddr |
Displays information about the Switch-Group related to a multicast group G. groupAddr specifies the address of the multicast group. |
The value ranges from 224.0.1.0 to 239.255.255.255, in dotted decimal notation. |
| reuse interval |
Displays information about the Switch-Group reused in an MD in a specified period. |
The value is an integer ranging from 1 to 2147483647, in seconds. |
| vpnSrcAddr |
Displays information about the Switch-Group related to a specified VPN multicast source. |
The value is in dotted decimal notation. |
| mask |
Indicates the mask of the VPN multicast group or source address. |
- |
| srcMaskLen |
Specifies the mask length of the VPN multicast source address. |
The value is an integer ranging from 0 to 32. |
| srcMask |
Specifies the mask of the VPN multicast source address. |
The value is in dotted decimal notation. |
| vpnGrpAddr |
Displays information about the Switch-Group related to a specified VPN multicast group. |
The value ranges from 224.0.1.0 to 239.255.255.255, in dotted decimal notation. |
| grpMaskLen |
Specifies the mask length of the VPN multicast group address. |
The value is an integer ranging from 4 to 32. |
| grpMask |
Specifies the mask of the VPN multicast group address. |
The value is in dotted decimal notation. |
| vpn-instance vpn-instance-name |
Specifies a VPN instance. vpn-instance-name specifies the name of a VPN instance. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string. |
Usage Guidelines
Usage Scenario
The display multicast-domain vpn-instance switch-group send command is used to display the Switch-Group information sent by the local router.
- Each VPN instance corresponds to one MD. If a VPN instance is specified by vpn-instance-name, an MD is specified accordingly. Therefore, the command can be used to display the information about the Switch-Group of a specified MD.
- The Switch-Group information is displayed in an ascending order of VPN (S, G) entries.
- If reuseIntv is specified, only the information about the Switch-Group that is reused in a specified interval is displayed in an ascending order of the Switch-Group address.
