If one active link fails, the other remaining active links will load balance the traffic.

It is also called as the manual mode because of its working process - users need to manually create a port-channel and add member interfaces to that port-channel.Īfter the aggregation links being established, all those links are active links to forward data packets. LAG (link aggregation group) refers to the initial technology to realize link bundling and load balancing without any protocol involved. Then active links will load balance data to do communication. However, if the Actor’s ports have the same priorities, the ports with smaller port numbers will be chosen to be active ports.Īfter the corresponding ports of two switches being selected, the port-channel (LACP group) is established. If the two switches have similar system priority, the switch with a smaller MAC address value will be the Actor.Īfter the Actor selected, the two switches will choose active ports based on the port priorities of Actor’s port. Then they will have a negotiation with each other to choose the higher one to be the Actor and the lower one being the Partner. After receiving LACPDUs from each other, the two switches will determine which side’s system priority is higher. Moreover, even if one link fails, under the LACP mode, the other available link members in the same LACP group will balance the load.Īt the moment LACP enabled between the two switches, they will send LACPDUs (LACP data units) to each other. The standard prescribes that LACP can be a method to bundle multiple physical links between network devices into a single logical link.Īs a result, links that LACP enabled, can increase its logical bandwidth and network reliability without changing any network infrastructure. LACP is a subcomponent of IEEE 802.3ad (Link Aggregation) standard. What Is LACP (Link Aggregation Control Protocol) and How does it Work? They also take over those traffic supposed to traverse via the failed one, so data packet won’t get lost. Even if one link fails, the remaining links between the two switches will still be running. LAG builds up multiple links between two switches, which expands bandwidth.īesides, it provides link-level redundancy in network failure and load-balance traffic. A Link Aggregation Group forms when we connect multiple ports in parallel between two switches and configure them as LAG. LAG (Link Aggregation Group) is an actual technique or instance for link aggregation.

Two terms often appear along with it, that is, LAG and LACP. Link aggregation is an approach to combine several individual (Ethernet) links into a single logical link.
