This section provides technical background information on the topics discussed in this chapter.

17.4.1 Static Trunking Example

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

Chapter 17 Link Aggregation
DESCRIPTION
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 Aggregation Control Protocol (LACP). The smaller the number, the higher the priority
level.
The field identifies the link aggregation group, that is, one logical link containing multiple ports.
Select this option to enable LACP for a trunk.
This field displays the port number.
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.
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 (1 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.
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.
Click Cancel to begin configuring this screen afresh.
