DESCRIPTION
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 Aggregate Control Protocol
(LACP). The smaller the number, the higher the priority level.
The field identifies the link aggregation group, that is, one logical link containing
multiple ports
Select this option to activate a trunk group.
Select this check box to enable LACP for a trunk.
This field displays the port number.
Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this
row first to set the common settings and then make adjustments on a port-by-port
basis.
Note: Changes in this row are copied to all the ports as soon as you
make them.
Select the trunk group to which a port belongs.
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.
Click Cancel to begin configuring this screen afresh.
