4.2.3 Aggregate Basic Setting
LACP determines the dynamic aggregation group members according to the priority of the
port ID on the end with the preferred device ID. The device ID consists of two-byte system
priority and six-byte system MAC address, that is, device ID = system priority + system MAC
address.
When two devices are compared, the system priorities are compared first, and the system
MAC addresses are compared when the system priorities are the same. The device with
smaller device ID will be considered as the preferred one.
There is a limit on the number of selected ports in an aggregation group. Therefore, if the
number of selected ports in an aggregation group exceeds the maximum member port
number supported by the device, the system will choose the ports with lower port numbers as
the member ports.
Set LACP system priority (from 1 to 65535).
4.2.4 LACP Status Setting
Set LACP port status as active or passive.
Passive: The port does not automatically send LACP protocol packets; it responds only if it
receives an LACP protocol packet from the peer device.
Active: The port automatically sends LACP protocol packets.
A link having either one or two active LACP ports can perform dynamic LACP trunking. If the
two LACP ports connected are passive, they will not perform dynamic LACP trunking as both
ports are waiting for LACP protocol packet from the peer device.
 Note:
The dynamic active LACP ports on this device can aggregate with the active or passive
LACP ports of the peer devices, but the passive LACP ports of this device can only
aggregate with the active LACP ports of the peer devices.
