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.
