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, which can result in broadcast storms and poor network
performance.
To delete 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 87 on page 217 is
displayed with the configuration of previously created trunks.
4. Select the Module pull-down list and choose the switch in the stack
with the port trunk you want to modify.
5. Click the circle next to the number of the trunk you want to modify.
You can select only one port trunk at a time.
6. Click Remove.
A confirmation prompt is displayed.
Click OK to delete the port trunk or Cancel to cancel the
procedure.
