What is Eth-Trunk for S series switches
Eth-Trunk, also called link aggregation, is a technique that bundles multiple physical links to a logical link to increase link bandwidth. For relevant protocols and standards, see IEEE 802.3ad. As the network scale expands increasingly, users pose increasingly higher requirements on the bandwidth and reliability of backbone links. Traditional technologies often use high-speed cards or devices supporting high-speed interface cards to increase the bandwidth. This method, however, is costly and inflexible. Link aggregation bundles multiple physical interfaces into a logical interface to increase the bandwidth without upgrading the hardware. In addition, link aggregation adopts the link backup mechanism to improve reliability of the links between devices. Link aggregation has the following advantages: 1. Increase bandwidth. The maximum bandwidth of a link aggregation group is the sum of bandwidth of the member interfaces. 2. Improve reliability. When a link fails, traffic is automatically switched to other member links. This ensures reliability of the link aggregation group. 3. Achieve load balancing. A link aggregation group can balance load among active member links.

How to configure the Eth-Trunk hash mode on S series switches
You can run the load-balance command to configure the Eth-Trunk hash mode on S series switches (except the S1700).

Default link aggregation mode on S series switches
By default, an Eth-Trunk on S series switches (except the S1700) works in manual load balancing mode.

What are the working modes for ETH-TRUNK ?
Working mode of the Eth-Trunk: NORMAL: manual load balancing mode LACP: LACP mode
