Creating a Port Trunk
This procedure explains how to create a port trunk.
Note
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 Advanced Config menu, select Trunk Config.
The Trunk Configuration page is shown in Figure 46.
Figure 46. Trunk Configuration 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.
