wwpOamLoopbackCommand
Module: WWP-OAM-MIB
OID (symbolic): WWP-OAM-MIB::wwpOamLoopbackCommand
OID (numeric): 1.3.6.1.4.1.6141.2.400.1.2.3.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute initiates or terminates remote loopback with an OAM peer. Writing startRemoteLoopback(2) to this attribute cause the local OAM client to send a loopback OAMPDU to the OAM peer with the loopback enable flags set. Writing stopRemoteLoopback(3) to this attribute will cause the local OAM client to send a loopback OAMPDU to the OAM peer with the loopback enable flags cleared. Writing noLoopback to this attribute has no effect.
Writes to this attribute are ignored unless the OAM status of this interface is 'operational' (wwpOamOperStatus).
The attribute always returns noLoopback on a read. To determine the loopback status, use the attribute wwpOamLoopbackStatus.
What is wwpOamLoopbackCommand?
Writing startRemoteLoopback(2) to this OID sends a Loopback OAMPDU asking the remote OAM peer to echo back all non-OAM frames it receives, while writing stopRemoteLoopback(3) ends it; the object always reads back as noLoopback(1). An admin uses this to run a disruptive but conclusive cable/link test, remembering that normal traffic on the remote end is blocked while loopback is active.
