Usage Guidelines

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.

Example

# Limit the bandwidth to 1000 kbit/s for each Eth-Trunk member interface.
