Select this checkbox to enable Link Aggregation Control Protocol (LACP).
System
Priority
Priority
LACP system priority is a number between 1 and 65,535. The switch with
the lowest system priority (and lowest port number if system priority is the
same) becomes the LACP “server”. The LACP “server” controls the
operation of LACP setup. Enter a number to set the priority of an active port
using Link Aggregation Control Protocol (LACP). The smaller the number,
the higher the priority level.

Timeout
Timeout
Timeout is the time interval between the individual port exchanges of LACP
packets in order to check that the peer port in the trunk group is still up. If
a port does not respond after three tries, then it is deemed to be “down”
and is removed from the trunk. Set a short timeout (one second) for busy
trunked links to ensure that disabled ports are removed from the trunk
group as soon as possible.

Select either 1 second or 30 seconds.

Click Apply to save your changes to the Switch’s run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
