The l2-multicast limit per-trunk-member bandwidth command limits the bandwidth to a specific value for each Eth-Trunk member interface.
The undo l2-multicast limit per-trunk-member bandwidth command cancels the configuration.
By default, the bandwidth is not limited to a specific value for any Eth-Trunk member interface.
| Parameter | Description | Value |
|---|---|---|
| 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. |
The value is an integer ranging from 1 to 4094. |
Usage Scenario
An Eth-Trunk interface's member interfaces may change dynamically. To implement refined bandwidth control, you can run the l2-multicast per-trunk-member limit bandwidth command to limit the bandwidth to a specific value for each Eth-Trunk member interface.
After the l2-multicast per-trunk-member limit bandwidth command is run, the total bandwidth limit for an Eth-Trunk interface is calculated using the following formula: Total bandwidth limit for an Eth-Trunk interface = Number of this Eth-Trunk interface's Up member interfaces x Bandwidth limit for each member 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.
