Link Aggregation Control Protocol (LACP) Configuration


LACP (802.3ad) provides the dynamic link aggregation function.

The LACPDU includes the LACP system priority, the system MAC, the port priority, and I.D. The port, included in the LACP LAG, will transmit the LACPDU to its neighbors.

The configuration of the LACP LAG is similar to that of the static LAG.

The min-selected-port label denotes that the LAG is up only when no fewer than the defined number of ports are up. Below, our defined number is 4.

Configuring LACP LAGs

admin@XorPlus# set interface aggregate-ethernet ae1 aggregated-ether-options lacp enable true
admin@XorPlus# set interface aggregate-ethernet ae1 aggregated-ether-options min-selected-port 4
admin@XorPlus# set interface gigabit-ethernet ge-1/1/1 ether-options 802.3ad ae1
admin@XorPlus# set interface gigabit-ethernet ge-1/1/2 ether-options 802.3ad ae1
admin@XorPlus# set interface gigabit-ethernet ge-1/1/3 ether-options 802.3ad ae1
