hh3cDot3OamUniqueEventNotificationRx

Module: HH3C-EFM-COMMON-MIB

OID (symbolic): HH3C-EFM-COMMON-MIB::hh3cDot3OamUniqueEventNotificationRx

OID (numeric): 1.3.6.1.4.1.25506.2.42.3.1.4.1.4

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A count of the number of unique Event OAMPDUs received on this interface. Event notification OAMPDUs may be sent in duplicate to increase the probability of successfully being received, given the possiblity that a frame may be lost in transit.

An Event Notification 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 Event code.

A unique Event Notification OAMPDU is indicated as an Event Notification OAMPDU with a Sequence Number field that is distinct from the previously received Event Notification OAMPDU Sequence Number.

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 hh3cDot3OamUniqueEventNotificationRx?

A running count of distinct (non-duplicate) Event Notification OAMPDUs received on this interface from its peer — the inbound counterpart to hh3cDot3OamUniqueEventNotificationTx, reflecting the number of actual link events the peer has reported.
