LACP between cisco and huawei

Hello everyone,

Today I will share with you the LACP between Cisco and Huawei.

Link aggregation is a computer networking term to describe various methods of combining (aggregating) multiple network connections in parallel to increase throughput beyond what a single connection could sustain and to provide redundancy in case one of the links fail.

Further umbrella terms used to describe the method include port trunking, link bundling, Ethernet/network/NIC bonding, or NIC teaming. These umbrella terms not only encompass vendor-independent standards such as Link Aggregation Control Protocol (LACP) for Ethernet defined in IEEE 802.1ax or the previous IEEE 802.3ad, but also various proprietary solutions.

LACP was designed to achieve the following:

Automatic addition and deletion of individual links to the aggregate bundle without user intervention.

Link monitoring to check whether both ends of the bundle are connected to the correct group.

Link aggregation addresses two problems with Ethernet connections: bandwidth limitations and lack of resilience.
With regard to the first issue: bandwidth requirements do not scale linearly. Ethernet bandwidths historically have increased by an order of magnitude each generation: 10 Megabit/s, 100 Mbit/s, 1000 Mbit/s, 10,000 Mbit/s. If one started to bump into bandwidth ceilings, then the only option was to move to the next generation which could be cost-prohibitive. An alternative solution, introduced by many of the network manufacturers in the early 1990s, is to combine two physical Ethernet links into one logical link via channel bonding. Most of these solutions required manual configuration and identical equipment on both sides of the aggregation.
The second problem involves the three single points of failure in a typical port-cable-port connection. In either the usual computer-to-switch or in a switch-to-switch configuration, the cable itself or either of the ports the cable is plugged into can fail. Multiple physical connections can be made, but many of the higher-level protocols were not designed to failover completely seamlessly.

That is all I want to share with you! Thank you!
