The l2-multicast limit bandwidth command limits the bandwidth to a specific value for a dot1q termination sub-interface.
The undo l2-multicast limit bandwidth command cancels the configuration.
By default, the bandwidth is not limited to a specific value for a dot1q termination sub-interface.
| Parameter | Description | Value |
|---|---|---|
| channel channel-name | Specifies a channel name. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
| bandwidth | Sets a bandwidth limit. |
The value is an integer ranging from 1 to 4194304, in kbit/s. |
| dot1q | Sets the dot1q termination mode. |
- |
| vid | Indicates a VLAN ID. |
- |
| vid1 | Sets a start VLAN ID. |
The value is an integer ranging from 1 to 4094. |
| to vid2 | Sets an end VLAN ID. vid2 must be greater than vid1. |
The value is an integer ranging from 1 to 4094. |
Usage Scenario
If a network provides services for multiple content providers, you can group a service provider's all multicast groups into one or more channels for management convenience. Then, you can configure tailored service rules for different content providers, including limiting the bandwidth to a specific value for multicast groups in a specific or all channels on a sub-interface.
During IPTV service deployment, if users demand a large number of channels, required bandwidth resources may exceed the total bandwidth resources of the aggregation network, overloading aggregation devices and deteriorating user experience. To resolve these issues, run the l2-multicast limit bandwidth command to limit the bandwidth to a specific value for a dot1q termination sub-interface.Prerequisites
A sub-interface has been configured as a dot1q termination sub-interface, and the sub-interface has been bound to an LDP-based VSI.
