ebrIfEthCollisionTestFailed
Module: DEC-ElanConc
OID (symbolic): DEC-ElanConc::ebrIfEthCollisionTestFailed
OID (numeric): 1.3.6.1.4.1.36.2.18.1.4.5.2.1.4
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of times that a Collision Presence Test (CPT) signal was not detected within 4 microseconds after a transmission on the line. This counter is valid only if ebrIfEthCollisionPresenceTestSwitch is set to true for this line.
What is ebrIfEthCollisionTestFailed?
Counts times a Collision Presence Test (heartbeat) signal was not detected within 4 microseconds after a transmission. This counter is only meaningful when ebrIfEthCollisionPresenceTestSwitch is enabled for the line, and rising counts suggest a failing transceiver.
