Both static and LACP LAGs can support the hashing of traffic using the Src/Dst MAC address, the Src/DstIP address, and Layer 4 port information.
If all member ports of a LAN are link-down, the LAG will be link-down. The LAG will become link-up when at least one member port is link-up.
The logical function and configuration of LAGs are same as those of a physical port.

Configuring Static LAGs

admin@XorPlus# set interface aggregate-ethernet ae1
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
