You can administratively lock a spoke-SDP by locking the host service using the admin-lock parameter of the tools command. The following conditions and constraints apply:
Both ends of a PW or MS-PW represented by a spoke-SDP must be administratively locked.
Test traffic can be injected into the spoke-SDP using a SAP defined within a test service. The test service must be identified in the tools command at one end of the locked PW.
All traffic is forwarded to and from the test SAP defined in the test service, which must be of a type that is compatible with the spoke-SDP.
Traffic to and from a non-test SAP is dropped. If no test SAP is defined, all traffic received on the spoke-SDP is dropped, and all traffic received on the paired SAP is also dropped.
If a spoke-SDP is administratively locked, it is treated as operationally down. If a VLL SAP is paired with a spoke-SDP that is administratively locked, the SAP OAM treats this as if the spoke-SDP is operationally down.
If a VPLS interface is paired to a spoke-SDP that is administratively locked, the L2 interface is taken down locally.
The control-channel-status must be shutdown before administratively locking a spoke-SDP.
