To allow changes to the circuit topology, we support the ability to delete circuits that were previously created by the circuit creation processing. The processing gets circuit names from the data file, searches the topology for an existing circuit with this name, and if found, removes the circuit. This is then repeated for each record in the circuit deletion data file.


Before running the Circuit Deletion command, open the corresponding Circuit Creation data file (sonet-sdh-circuit- create.txt, lo-sonet-sdh-circuit-create.txt, or wdm-circuit-create.txt) and comment out or delete the lines containing the circuits to be deleted. Otherwise, the circuits will be created again on server startup.
