ifMauFalseCarriers

Module: DOT3-MAU-MIB

OID (symbolic): DOT3-MAU-MIB::ifMauFalseCarriers

OID (numeric): 1.3.6.1.2.1.26.2.1.1.9

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A count of the number of false carrier events during IDLE in 100BASE-X and 1000BASE-X links.

For all other MAU types, this counter will always indicate zero. This counter does not increment at the symbol rate.

It can increment after a valid carrier completion at a maximum rate of once per 100 ms for 100BASE-X and once per 10us for 1000BASE-X until the next CarrierEvent.

This counter can roll over very quickly. A management station is advised to poll the ifMauHCFalseCarriers instead of this counter in order to avoid loss of information.

Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.

What is ifMauFalseCarriers?

A running count of false carrier events on this 100BASE-X or 1000BASE-X interface during idle periods; since it can roll over quickly at gigabit speeds, the MIB recommends polling the 64-bit ifMauHCFalseCarriers instead for accurate long-term tracking.
