Modifying a Port Trunk
This procedure adds and removes ports from a port trunk.
Note
You should disconnect the cables from the ports of the trunk on the
switch before modifying it. Adding or removing ports from a trunk
without first disconnecting the cables can create loops in your
network topology, which can cause broadcast storms and poor
network performance.
To add or remove ports from a trunk, perform the following procedure:
1. From the Main Menu, type A to select Advanced Switch
Configuration.
The Advanced Switch Configuration Menu is shown in Figure 15 on
page 75.
2. From the Advanced Switch Configuration Menu, type T to select
Trunk Configuration.
The Trunk Configuration Menu is shown in Figure 16 on page 76.
3. To add ports to a port trunk, type A to select Add Trunk Member. To
remove ports, type R to select Remove Trunk Member.
The following prompt is displayed:
Enter trunk group number>
4. Type the number of the trunk group you want to modify and press
Enter.
The following prompt is displayed:
Enter port members (up to 8 ports) for trunk n >
5. Enter the ports you want to add or remove from the trunk and press
Enter.
You can specify the ports individually, separated by commas (for
example, 1,2,5), as a range of ports separated by a hyphen (for
example, 2-4), or both (for example, 1,3, 6-8).
6. Modify the port trunk on the other switch and reconnect the cables.
