multicast-list (Multicast bandwidth view)
Function
The multicast-list command sets the parameters for multicast program bandwidth.
The undo multicast-list command cancels the bandwidth for the multicast program list.
By default, the bandwidth for multicast program list is not configured.
This command is supported only on the NetEngine 8000 F1A.
Format
multicast-list { name list-name | index list-index | start-list-index start-list-index end-list-index end-list-index } { bandwidth bandwidth-value | detect-interval interval threshold threshold }
undo multicast-list { name list-name | index list-index | start-list-index start-list-index end-list-index end-list-index }
Parameters
| Parameter | Description | Value |
|---|---|---|
| name list-name |
Specifies the name of a multicast program list. |
The name is a string of 1 to 32 characters. |
| index list-index |
Specifies the index of the multicast program list. |
The value is an integer ranging from 0 to 8191. |
| start-list-index start-list-index |
Specifies the start index of the multicast program lists. |
The value is an integer ranging from 0 to 8191. |
| end-list-index end-list-index |
Specifies the end index of the multicast program lists. |
The value is an integer ranging from start-list-index to 8191. |
| bandwidth bandwidth-value |
Indicates the static bandwidth for multicast programs. |
The value is an integer ranging from 10 to 400000. The unit is kbit/s. |
| detect-interval interval |
Specifies the interval for making statistics of the dynamic bandwidth for multicast programs. |
The value is an integer ranging from 15 to 1800. The value of interval must be a multiple of 15. The unit is second. |
| threshold threshold |
Specifies the threshold of bandwidth change for multicast programs. |
The value is an integer ranging from 1 to 100.The unit is %. |
Usage Guidelines
Usage Scenario
The bandwidth for multicast programs is as follows:
- Static bandwidth: set by bandwidth-value. The NetEngine 8000 F always allocates bandwidth-value bandwidth to the multicast programs, rather than the bandwidth actually required by the multicast programs.
- Dynamic bandwidth: set by interval and threshold. The NetEngine 8000 F collects statistics about the program bandwidth every interval seconds. If the threshold of the bandwidth change does not exceed threshold, the program bandwidth is normal. If the threshold of the bandwidth change exceeds threshold, the unicast bandwidth is adjusted without changing the total bandwidth of the user. The adjustment range of unicast bandwidth cannot exceed the bandwidth reserved for unicast. The multicast-list command configuration takes effect for subsequent users that go online after this command is run only when the multicast-list command in the AAA view is also run.
Precautions
In VS mode, this command is supported only by the admin VS.
