Description: A count of OAMPDUs received that contain the Loopback Control code specified in Table 57-4. This counter is incremented on reception of a valid frame, with (1) destinationField equal to the reserved multicast address for Slow_Protocols specified in CROSS REF Table 43B-1, (2) lengthOrType field value equal to the reserved Type for Slow_Protocols as specified in CROSS REF Table 43B-2, (3) a Slow_Protocols subtype value equal to the subtype reserved for OAM as specified in Table 43B-3, (4) the OAM code equals the Loopback Control code and is supported by the device.
What is nbsEfmOamLoopbackControlRx?
This OID counts received OAMPDUs carrying the Loopback Control code (Table 57-4) that this device supports. An admin checks this to confirm the local device is receiving loopback control requests from its peer, e.g. during a remote-initiated loopback test.
