Trunks 

 

 
This page allows you to configure LACP for each port. The switch supports both static trunking 
and dynamic Link Aggregation Control Protocol (LACP). LACP configured ports can 
automatically negotiate a trunked link with LACP-configured ports on another device. You can 
configure any number of ports on the switch as LACP, as long as they are not already 
configured as part of a static trunk. If ports on another device are also configured as LACP, the 
switch and the other device will negotiate a trunk link between them. If an LACP trunk consists 
of more than eight ports, all other ports will be placed in a standby mode. Should one link in 
the trunk fail, one of the standby ports will automatically be activated to replace it. The LACP 
Table has one row for each port and three columns.  
 
The columns are:  
 

•  Port - The front-panel port number.  
•  LACP Enabled on Port - Allows LACP to be enabled or disabled. When the box is 

checked, LACP is enabled.  

•  Key Value (0..255, 0 means auto-generated key) - Used to determine the link 

aggregation group membership, and to identify this device to other switches during 
negotiations.  

 

There are three main buttons associated with this page:  
 

•  HELP - Displays this text.  
•  APPLY - Updates the switch configuration. No changes are made to the configuration 

until this button is pressed.  

•  REFRESH - Reloads the current page with the latest configuration settings.
