dot3OamLoopbackCommand
Module: EFM-COMMON-MIB
OID (symbolic): EFM-COMMON-MIB::dot3OamLoopbackCommand
OID (numeric): 1.3.6.1.2.1.9908.1.3.1.1
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' (dot3OamOperStatus).
The attribute always returns noLoopback on a read. To determine the loopback status, use the attribute dot3OamLoopbackStatus.
What is dot3OamLoopbackCommand?
Writing startRemoteLoopback(2) sends a loopback OAM PDU asking the peer to echo back all non-OAM traffic it receives on this link, which is disruptive since normal traffic stops flowing at the peer while it's looped; writing stopRemoteLoopback(3) ends it, noLoopback has no effect, and the set is ignored unless dot3OamOperStatus is operational — use dot3OamLoopbackStatus to check the actual state, since reads of this object always return noLoopback.
