Network class learning time of this phase: September 13th – September 18th.
Answer time of this class: September 17th, 8 AM - September 18th, 4 PM (UTC+0).


Class topic

Post 1. Introduction of the link aggregation

Ethernet link aggregation, also called Eth-Trunk, bundles multiple physical links into a logical link to increase link bandwidth. The bundled links back up each other, increasing reliability...More


Post 2. Link Aggregation - Forwarding Principle

An Eth-Trunk link is deployed on the data link layer, that is, between the physical layer and the MAC sub-layer...More


Post 3. Eth-Trunk in Manual Load Balancing Mode

Huawei network devices support two Eth-Trunk working modes: Manual load balancing mode and LACP mode...More


Post 4. The working principle and characteristics of LACP

The LACP protocol uses LACPDU (Link Aggregation Control Protocol Data Unit) to exchange information with the opposite end to achieve link aggregation...More


Post 5. Interoperation and Replacement Guide for Link Aggregation on Huawei and Cisco Switches

The implementation mechanism of link aggregation in manual load balancing mode and LACP mode on Huawei switches is similar to that on Cisco switches, but commands and default settings are different...More
