cieIfCarrierTransitionCount

Module: CISCO-IF-EXTENSION-MIB

OID (symbolic): CISCO-IF-EXTENSION-MIB::cieIfCarrierTransitionCount

OID (numeric): 1.3.6.1.4.1.9.9.276.1.1.2.1.4

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: Number of times interface saw the carrier signal transition.

For example, if a T1 line is unplugged, then framer will detect the loss of signal (LOS) on the line and will count it as a transition.

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

What is cieIfCarrierTransitionCount?

Counts how many times the interface's carrier signal transitioned, such as a loss-of-signal event on a T1 line when it is unplugged.

Examples
