Module: CISCO-IF-EXTENSION-MIB

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

OID (numeric): 1.3.6.1.4.1.9.9.276.1.1.2.1.9

Node type: OBJECT-TYPE

Type: IfOperStatusReason

Access: read-only

Description: This object represents the detailed operational cause reason for the current operational state of the interface. The current operational state of the interface is given by the 'ifOperStatus' defined in IF-MIB.

The corresponding instance of 'cieIfOperStatusCauseDescr' must be used to get the information about the operational cause value mentioned in this object.

For interfaces whose 'ifOperStatus' is 'down' the objects 'cieIfOperStatusCause' and 'cieIfOperStatusCauseDescr' together provides the information about the operational cause reason and the description of the cause.

The value of this object will be 'none' for all the 'ifOperStatus' values except for 'down'. Its value will be one status cause defined in the 'IfOperStatusReason' textual convention if 'ifOperStatus' is 'down'.

The value of this object will be 'other' if the operational status cause is not one defined in 'IfOperStatusReason'.

What is cieIfOperStatusCause?

Reports the detailed cause code for the interface's current operational status as reflected by IF-MIB's ifOperStatus, giving more insight into why the interface is up or down.
