h3cDot3OamLoopbackControlRx
Module: A3COM-HUAWEI-EFM-COMMON-MIB
OID (symbolic): A3COM-HUAWEI-EFM-COMMON-MIB::h3cDot3OamLoopbackControlRx
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.42.3.1.4.1.8
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of the number of Loopback Control OAMPDUs transmitted on this interface.
An Loopback Control OAMPDU is indicated by a valid frame with (1) destination MAC address equal to that of the reserved MAC address for Slow Protocols (See 43B of [802.3ah]), (2) a lengthOrType field equal to the reserved type for Slow Protocols, (3) a Slow Protocols subtype equal to that of the subtype reserved for OAM, and (4) an OAMPDU code equals the OAM Loopback Control code.
Discontinuities of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of the ifCounterDiscontinuityTime.
What is h3cDot3OamLoopbackControlRx?
This read-only counter tallies Loopback Control OAMPDUs received from the peer, indicating remote loopback test requests. Operators monitor it to understand how often the peer is requesting loopback diagnostics and to validate bidirectional control plane communication. An increasing count confirms the peer is actively testing.
