hpnicfDot3OamLoopbackControlRx
Module: HPN-ICF-EFM-COMMON-MIB
OID (symbolic): HPN-ICF-EFM-COMMON-MIB::hpnicfDot3OamLoopbackControlRx
OID (numeric): 1.3.6.1.4.1.11.2.14.11.15.2.42.3.1.4.1.8
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 hpnicfDot3OamLoopbackControlRx?
This counts Loopback Control OAMPDUs received on this interface, i.e. loopback start/stop requests coming from the peer. Admins watch for unexpected increases here, which would indicate the remote device is attempting to initiate loopback on this link (relevant alongside hpnicfDot3OamLoopbackIgnoreRx's ignore/process setting).
