LABEL DESCRIPTION
Link Aggregation Control Protocol
Active Select this checkbox to enable Link Aggregation Control Protocol (LACP).
System
Priority
LACP system priority is a number between 1 and 65535. 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.
Index The index identifies the trunk group, that is, one logical link containing multiple ports
Active Make sure to select this check box to activate the trunk group. You may temporarily
deactivate a trunk group without deleting it by clearing this check box.
Starting Port This is the beginning port in the trunk group’s port range and is not configurable (see
Table 27 on page 107).
Ending Port Select the end port in the port range from the drop-down list box if applicable (see
Table 27 on page 107).
LACP Select this check box to enable LACP for a trunk.
LACP 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.
Apply Click Apply to save your changes back to the switch.
