Creating 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 effect the operations of your
network.
Note
A port trunk contains a group of 2 to 8 ports. The maximum number
of ports in a trunk is 8.
To create a port trunk, perform the following procedure:
1. From the Home page, select Configuration.
2. From the Configuration page, select Layer 1.
3. Select the Port Trunking tab.
The Port Trunking tab window in Figure 81 is displayed.
