LABEL DESCRIPTION
Link Aggregation 
Control Protocol
Note: Do not configure this screen unless you want to enable dynamic link aggregation.
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 Aggregation 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.
