What standard is LACP?

LACP is a data link layer protocol defined in IEEE 802.3ad standard. It provides a method to control the bundling of several physical ports together to form a single logical channel. It enables a network device, typically a data switch, to negotiate an automatic bundling of links by sending LACP packets to the peer.

How does LACP load balance?

Load Balancing in LACP Mode To prevent out-of-order packets, Eth-Trunk uses flow-based load balancing. This mechanism uses the hash algorithm to calculate the address in a data frame and generate a hash key based on which the system searches for the outbound interface in the Eth-Trunk forwarding table.

What are LACP States?

The LACP port state (also known as the actor state) field is a single byte, each bit of which is a flag indicating a particular status. In this table, mux (i.e. a multiplexer) refers to the logical unit which aggregates the links into a single logical transmitter/receiver.

What is LACP priority?

LACP uses the port priority with the port number to form the port identifier. The port priority determines which ports should be put in standby mode when there is a hardware limitation that prevents all compatible ports from aggregating.

Is LACP active active?

LACP runs on any link that is configured to be in the active state. The port in an active mode also automatically initiates negotiations with other ports by initiating LACP packets. Passive mode—the interface is not in an active negotiating state. LACP runs on any link that is configured in a passive mode.

What is network LACP?

Defined within IEEE 802.3ad, the Link Aggregation Control Protocol (LACP) is a standards-based method to control the bundling of several physical network links together to form a logical channel for increased bandwidth and redundancy purposes.

Does LACP double bandwidth?

LACP will not split packets across multiple interfaces for a single stream/thread. For example a single TCP stream will always send/receive packets on the same NIC.

How many ports can LACP bundle?

You can optionally configure LACP for link protection. You can create up to eight Ethernet ports in each bundle.
