Chapter 15 Link Aggregation

The following table describes the labels in this screen.

Table 30   Link Aggregation Control Protocol: Configuration 

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 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.  

Group ID

The field identifies the link aggregation group, that is, one logical link containing 

multiple ports 

Active

Select this option to activate a trunk group.  

Dynamic 

(LACP) 

Select this check box to enable LACP for a trunk.

Port

This field displays the port number. 

Group

Select the trunk group to which a port belongs. 

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
