15.6 Static Trunking Example
This example shows you how to create a static port trunk group for ports 2-5.
1 Make your physical connections - make sure that the ports that you want to belong to
the trunk group are connected to the same destination. The following figure shows ports
2-5 on switch
A connected to switch B .

Configure static trunking - Click Advanced Application > Link Aggregation > Link
Aggregation Setting . In this screen activate trunking group T1 and select the ports that
should belong to this group as shown in the figure below. Click Apply when you are
done.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this
row first to set the common settings and then make adjustments on a port-by-port
basis.
Note: Changes in this row are copied to all the ports as soon as you
make them.
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 to the Switch’s run-time memory. The Switch loses
these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are done
configuring.
Cancel Click Cancel to begin configuring this screen afresh.
