34.5.1 Static Trunking Example
This example shows you how to create a static port trunk group for ports 2
–
5.

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 PORT > Link Aggregation > Link Aggregation Setting . In this screen
activate trunk group T1 , select the traffic distribution algorithm used by this group and select the ports
that should belong to this group as shown in the figure below. Click Apply when you are done.
SLOT This field appears only in Stacking mode. Click the drop-down list to choose the slot number of the
Switch in a stack.
Port This field displays the port number. In Stacking mode, the first number represents the slot ID and
the second is the port number. Please note that the default stacking ports (the last four ports of
your Switch) cannot be configured. They are reserved for stacking only.
* 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 (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.
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.
