Creating a Port Trunk
This procedure explains how to create a port trunk.
Caution
Do not connect the cables of a port trunk to the ports on the switch
until after you have configured the ports on both the switch and the
end node. Connecting the cables prior to configuring the ports can
create loops in your network topology. Loops can result in broadcast
storms, which can adversely affect the operation of your network.
To create a port trunk, perform the following procedure:
1. From the Bridge folder, select Spanning Tree.
2. From the Spanning Tree folder, select Trunking.
The Trunking page is shown in Figure 69.
Figure 69. Trunking Page
If the switch does not contain a port trunk, all of the ports on the switch
are unchecked. If there is a port trunk, the ports in the trunk are
checked.
