emdi channel
Function
The emdi channel command adds a multicast channel to an EMDI channel group.
The undo emdi channel command deletes a multicast channel from an EMDI channel group.
By default, no multicast channel exists in an EMDI channel group.
This command is supported only on the NetEngine 8000 F1A.

The value ranges from 224.0.1.0 to 239.255.255.255, in dotted decimal notation. |
| vpn-instance vpn-instance-name |
Specifies a VPN instance name. |
The name is a string of 1 to 31 case-sensitive characters, spaces not supported. |
| vlan vlan-id |
Specifies a VLAN ID. |
The value is an integer ranging from 1 to 4094. |
| vsi vsi-name |
Specifies the name of a VSI. |
The name is a string of 1 to 31 case-sensitive characters, spaces not supported. |
| bd bd-id |
Specifies the number of a BD. |
The value is an integer ranging from 1 to 16777215. |
| transit |
Indicates that detection is performed on Ps. |
- |
| pt pt-value |
Specifies the payload type of an RTP packet, which corresponds to the Payload type value in the RTP header of a multicast packet. |
The value is an integer ranging from 25 to 34 or from 96 to 127. The default value is 33. |
| clock-rate clock-rate-value |
Specifies the clock frequency of RTP packets. |
The value is an enumerated type:
|
| uncompressed |
Indicates uncompressed streams for EMDI detection. |
- |
| sub-domain sub-domain-value |
Specifies the sub-domain. |
The value is an integer that ranges from 0 to 255. |
| bsl bsl-value |
Specifies the bit string length. |
The value is 64 or 128 or 256. |
Usage Guidelines
Usage Scenario
Multicast channels to be detected need to be configured before the EMDI detection solution is used. After an EMDI channel group has been created using the emdi channel-group command, run the emdi channel command to add a specified multicast channel to the EMDI channel group to complete configuration of the EMDI detection channel.
Prerequisites
An EMDI channel group has been created using the emdi channel-group command.
Precautions
- Different channels cannot be configured with the same channel name.
- A channel can be configured only in one channel group.
- In IPTV scenarios, the default value of pt-value parameter is 33.
- When multicast channels are configured for uncompressed streams, the uncompressed parameter is mandatory.
