Huawei quidway s7700 - Configuring the Eth-Trunk to Work in Manual Load Balancing Mode

Applicable Environment
When the bandwidth or the reliability of two devices should be increased and either of the two
devices does not support LACP, you should create an Eth-Trunk in manual load balancing mode
on Switches and add member interfaces to the Eth-Trunk to increase the bandwidth and improve
reliability of devices.
As shown in Figure 2-2, Eth-Trunks are created between SwitchA and SwitchB.

Pre-configuration Tasks
Before configuring an Eth-Trunk in manual load balancing mode, complete the following tasks:
l Powering on the S7700
l Creating the Eth-Trunks
Data Preparation
To configure an Eth-Trunk in manual load balancing mode, you need the following data.
No.
Data
1 Number of the Eth-Trunk in manual load balancing mode
2 Type and number of the member interface

Mode
Context
NOTE
Check whether the Eth-Trunk contains member interfaces before you configure the operation mode of the
Eth-Trunk. If the Eth-Trunk contains member interfaces, the operation mode of the Eth-Trunk cannot be
changed. To delete member interfaces from the Eth-Trunk, run the undo eth-trunk trunk-id command in
the interface view or run the undo trunkport interface-type interface-number command in the Eth-Trunk
view.
Do as follows on the S7700 where you need to configure an Eth-Trunk in manual load balancing
mode.
