Procedure: Cancel the Circuit Creation and Start Over

Step 1 Cancel the circuit creation:

•Click the Cancel button.

•Click the Back button until you return to the initial circuit creation window.

Step 2 Check the list of available ports. The previously selected port no longer appears in the available list because it is now part of a provisioned circuit.

Step 3 Select a different available port and begin the circuit creation process.
