priority and MAC address of this system, priority, number and operation key of the port. Upon receiving

the information, the peer compares the information with the information of other ports on the peer

device to determine the ports that can be aggregated. In this way, the two parties can reach an

agreement in added/removed to/from a dynamic aggregation group.

Extended LACP function

By using expansion fields in LACPDUs, you can expand the functions of LACP. For example, by

defining a new Type/Length/Value (TLV) data field among the expansion fields of the LACPDUs, you

can deliver the LACP multi-active detection (MAD) mechanism in an Intelligent Resilient Framework

(IRF) stack.

S5600 series that support extended LACP functions can be used as an IRF member device or an

intermediate device in LACP MAD implementation.

For details about IRF, member devices, intermediate devices, and the LACP MAD mechanism, see

the IRF Fabric operation.

Operational Key

When aggregating ports, link aggregation control automatically assigns each port an operational key

based on the port speed, duplex mode, and basic configurations described in

Considerations for the Ports in

In a manual or static link aggregation group, the selected ports are assigned the same operational

In a dynamic link aggregation group, all member ports are assigned the same operational key.

To participate in traffic sharing, member ports in an aggregation group must use the same

configurations with respect to STP, QoS, GVRP, QinQ, VLAN, port attributes and so on as shown in the

following table.
