Remove the Encryption Parameters from a MPLS Tunnel
Remove the Encryption parameters
Remove the MPLS tunnel endpoint encryption parameters
Proceed as follows: 
1. In FOXMAN-UN start the Ethernet Networking Package:
NEM Desktop - Application - Ethernet Networking Package….
2. Open the “Tunnel” tab:
Select the tunnel to be deleted
Open the “Edit” menu and click “Delete Tunnel”
Confirm the warning message with “Yes”
3. The FOXMAN-UN performs the following tasks:
- FOXMAN-UN sends a tunnel deletion request to the DIRAC server.
- The DIRAC server checks the synchronization between FOXMAN-UN and the DIRAC server database.
- The DIRAC server checks the deletion feasibility.
- The DIRAC server sends the tunnel deletion command to the targeted Crypto Engines.
- The DIRAC server checks the result of the operation in the SENC1 Crypto Engines and, in case of success, deletes the tunnel from its database and updates the configuration identifier.
- The DIRAC server sends back the response to the FOXMAN-UN.
Result: The tunnel is removed from the FOXMAN-UN and DIRAC server database, and the encrypted tunnel endpoints have been removed from the involved SENC1 Crypto Engines via the DIRAC server.
Check the encryption parameters
Proceed as follows: 
1. In FOXMAN-UN start the Ethernet Security Manager:
NEM Desktop - Application - Ethernet Security Manager….
2. In the “Crypto Configurations” tab check that the involved MPLS tunnel endpoints have been removed from the SENC1 Crypto Engines.
Result: The encryption parameters are checked.
