How to configure Eth-Trunk between ZTE devices and stacked S series switches


S series switches (except the S1700) that set up a stack can be connected with non-Huawei devices using Eth-Trunk in LACP mode.

The difference between E-trunk and Eth-Trunk on S series switches
For S series switches (except the S1700): Eth-Trunk, also called link aggregation, bundles multiple physical links to form a logical link to increase link bandwidth. The bundled links can enhance link reliability through mutual backup. E-Trunk (Enhanced Trunk), developed from LACP (a link aggregation protocol for a single device), is a mechanism that implements link aggregation among multiple devices. E-Trunk achieves device-level link reliability, instead of card-level link reliability previously achieved by LACP.

Does an S series switch support link aggregation after stacking configuration
S series switches (except the S1700) support link aggregation after stacking configuration.

Does the Eth-Trunk specifications change after S series switches are stacked together
Eth-Trunk specifications remain unchanged after S series switches (except the S1700) are stacked together.

Number allocation of Eth-Trunk member interfaces on stacked S series switches
After you configure an Eth-Trunk on stacked S series switches (except the S1700), the member interface number remain unchanged even if you split the stack and stack the switches again.
