Deleting a Port Trunk
Caution
Disconnect the cables from the port trunk on the switch before
performing the following procedure. Deleting a port trunk without
first disconnecting the cables can create loops in your network
topology. Data loops can result in broadcast storms and poor
network performance.
To delete a port trunk from the switch, perform the following procedure:
1. From the Home Page, select Configuration.
The System page is displayed with the General tab selected by
default, as shown in Figure 194 on page 586.
2. From the Configuration menu, select Layer 1.
The Layer 1 page opens with the Port Settings tab displayed by
default, as shown in Figure 203 on page 610.
3. Select the Port Trunking tab.
The Port Trunking tab is shown in Figure 210 on page 630.
4. Click the button next to the port trunk you want to delete and click
Remove.
The port trunk is deleted from the switch.
5. To permanently save the change, use the Save Changes button in the
General tab. For directions, refer to Saving Your Parameter Changes
on page 577.
