Chapter 5: Port Trunking

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 14 on page 59.

2.From the Advanced Switch Configuration Menu, type T to select Trunk Configuration.

The Trunk Configuration Menu is shown in Figure 15 on page 60.

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, 4,6,11-14).

6.Type Q to select Quit to previous menu and save your changes.

7.Modify the port trunk on the other switch and reconnect the cables.
