Description: Identification of cause for failure in changing the status of an interface. interfaceInService(1) Most, if not all, modifications require that the interface be out of service. interfaceNotNew(2) Some modifications require that the interface must never have been in service. interfaceExists(3) Some modifications, such as setting the interface type, require that no interface exists. (type must be unconfigured). bridgeGroupActive(4) For setting the bridgeDomainNumber in bridge or router interfaces. to add an interface to a bridgeGroup, the bridgeGroup must be in service. signalingNotEnabled(5) For this interface to be created, signaling must be enabled. firmwareOutOfDate(6) The firmware for the i/o card does not work with this interface. t1SigEnableInterfaceNotSupported(7) The interface is not supported if T1 signaling is enabled ts16ForData(8) ts16 has been set for passing data and the user attempts to turn on signaling. dbcesConfigured(9) Signaling cannot be disabled because this interface is configured as dbces. signalingEnabled(10) Signaling is on for at least one of the channels while trying to change e1 TS16 from CAS to CCS. cmCardTypeNotSupported(11) CM_NET interface is only supported by DS3 DS1 OC3 and SUPER_DS1 cards cmMultipleIntfNotSupported(12) only one interface can be configured as CM_NET cmIntfInService(13) CM_NET interface is in-service cmInterfaceConfigured(14) CM_NET interface is configured channelizationEnabled(15) A port can not be channelized in order to support unstructured CE. unstructuredCEConfigured(16) A port which has been channelized can not be configured to support unstructured CE. firmwareOutOfDate-ts16CAS-unsupported(17) ts16CAS is not supported by the firmware firmwareOutOfDate-interfaceType-unsupported(18) interface type is not supported by the firmware firmwareOutOfDate-ts16-unsupported(19) ts16 is not supported by the firmware invalidPortMap(20) invalid port map otherInterfacesExistOnThisPort(21) ISDN interface needs all 24 channels on the port.

What is interfaceFailureReasonCode?

This read-only integer indicates why an attempt to change the status of an interface failed, with codes like interfaceInService(1) meaning modifications require the interface to be out of service first. Engineers monitor this when they're trying to bring interfaces up or down and need to understand why the operation is being blocked. For example, if you get interfaceNotNew(2), it means the interface cannot be modified because it has previously been in service.

Examples
