wwpLeosOamLoopbackCommand
Module: WWP-LEOS-OAM-MIB
OID (symbolic): WWP-LEOS-OAM-MIB::wwpLeosOamLoopbackCommand
OID (numeric): 1.3.6.1.4.1.6141.2.60.400.1.2.3.1.1
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' (wwpLeosOamOperStatus).
The attribute always returns noLoopback on a read. To determine the loopback status, use the attribute wwpLeosOamLoopbackStatus.
What is wwpLeosOamLoopbackCommand?
Writing startRemoteLoopback(2) sends a loopback OAMPDU asking the peer to echo back everything it receives on this port except OAMPDUs, disrupting normal traffic there; writing stopRemoteLoopback(3) ends it; noLoopback(1) has no effect and is always what a read returns. This write only takes effect if OAM on the port is already operational, and since loopback is disruptive it should be used deliberately for cable/path testing, not as a routine command.
