What Is CISCO-IF-CALL-SERVICE-MIB?

CISCO-IF-CALL-SERVICE-MIB manages per-interface call-service state on Cisco media gateways, covering voice-capable interfaces that handle telephony call setup and teardown. It exposes operational and administrative state for call services per interface, along with graceful shutdown timers and repeated-service-action tracking. This supports monitoring the software/service status of voice interfaces, since cicServiceOperState diverging from cicServiceAdminState (e.g., an interface administratively Up but operationally Down) signals a fault in the call-processing service on that interface, and repeated cicServiceRepeatOwner/cicServiceRepeatResult entries reveal repeated failed service actions. It has no stated dependency on other IETF MIBs beyond general interface conventions but is closely tied to Cisco's voice gateway MIB family. It is deployed on Cisco media gateways and voice-enabled routers providing PSTN or VoIP call services. Network engineers evaluating or troubleshooting this functionality can download the CISCO-IF-CALL-SERVICE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-IF-CALL-SERVICE-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Cisco media gateways
Cisco voice gateway routers

Monitoring Examples

An operator checks cicServiceTable (cicServiceEntry rows) comparing cicServiceAdminState to cicServiceOperState for each voice interface to spot interfaces stuck in a degraded operational state despite being administratively enabled. Reviewing cicServiceGraceTime and cicServiceRepetition helps confirm whether a graceful shutdown is in progress versus a hung state, while a growing cicServiceRepeatResult failure count for a given cicServiceRepeatOwner flags a service action that keeps failing. ciscoIfCallServiceMIBNotifs traps would fire on state transitions for real-time alerting.

What Can Be Monitored

call service admin state
call service operational state
graceful shutdown grace time
service action repetition count
repeated service action result
service state change notifications

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoIfCallServiceMIB	1.3.6.1.4.1.9.9.9968			The MIB is used to manage call service state for interfaces on media gateway.
ciscoIfCallServiceMIBNotifs	1.3.6.1.4.1.9.9.9968.0
ciscoIfCallServiceMIBObjects	1.3.6.1.4.1.9.9.9968.1
cicServiceConfig	1.3.6.1.4.1.9.9.9968.1.1
cicServiceTable	1.3.6.1.4.1.9.9.9968.1.1.1		not-accessible	This table defines the parameters related to the call service state administration for the interfaces on media gateway. The possible interfaces include channelized sonet interface, DS1 interface, etc..
cicServiceEntry	1.3.6.1.4.1.9.9.9968.1.1.1.1		not-accessible	An entry containing service administration information applicable to a particular interface.
CIF cicServiceOperState	1.3.6.1.4.1.9.9.9968.1.1.1.1.1	CIfCallServiceOperState	read-only	This object indicates the current operating state of the service in the interface. The entry in this table is also in ifTable(the index of this table is ifIndex). The 'cicServiceOperState' of the entry is not only dependent on the 'cicServiceAdminState', it is also dependent on the 'ifOperStatus' of ifTable. The following is the relationship between 'cicServiceAdminState' and 'ifOperStatus': cicServiceOperState cicServiceAdminState ifOperStatus ---------------- ----------------- ------------ inService inService up outOfService forcefulOutOfService up oosPending gracefulOutOfService up outOfService inService down outOfService forcefulOutOfService down outOfService gracefulOutOfService down
CIF cicServiceAdminState	1.3.6.1.4.1.9.9.9968.1.1.1.1.2	CIfCallServiceAdminState	read-write	This object is used to change the desired service state of the interface. The operational service state of the interface is indicated by 'cicServiceOperState'.
U32 cicServiceGraceTime	1.3.6.1.4.1.9.9.9968.1.1.1.1.3	Unsigned32	read-write	This object specifies the amount of time before the existing call connections been gracefully shutdown in the interface when 'cicServiceAdminState' is set to 'gracefulOutOfService'. This object is not applicable if 'cicServiceAdminState' is set to 'forcefulOutOfService'. The value of 0 specifies that the service on the interface will not be put outOfService until the call connection over the interface is terminated.
CON cicServiceRepetition	1.3.6.1.4.1.9.9.9968.1.1.1.1.4	ConfigIterator	read-write	This object is used to change service state to multiple interfaces by repeatedly applying the writable objects of cicServiceTable specified in the same SNMP PDU starting from the row specified by the instance value in INDEX for the number of rows specified in this object. The order of operation is iterated through the logical order of the interface. Whether the iteration will be applied across the physical boundary or not is depends upon the system implementation. The GET operation on this object will always return 1.
STR cicServiceRepeatOwner	1.3.6.1.4.1.9.9.9968.1.1.1.1.5	OwnerString	read-write	This object is used for error checking of the operation specified in 'cicServiceRepetition'. The value of this object is set by the SNMP manager with its own identifier at the same time as issuing the bulk operation by setting 'cicServiceRepetition'. This object and 'cicServiceRepetition' need to be in the same SNMP SET PDU. Later on, the SNMP manager should check the value of this object, if it is same as the name previously set, then the value of 'cicServiceRepeatResult' indicates the result of the bulk operation initiated by this SNMP manager. In the case that a SNMP manager do multi bulk operation, it is recommended that the SNMP manager choose to set this value to its IP Address so as to be unique.
BUL cicServiceRepeatResult	1.3.6.1.4.1.9.9.9968.1.1.1.1.6	BulkConfigResult	read-only	This object is used for error checking of the operation specified in cicServiceRepetition. This object indicates the result of the bulk operation initiated by the SNMP manager specified in the value of 'cicServiceRepeatOwner'.
ciscoIfCallServiceMIBConformance	1.3.6.1.4.1.9.9.9968.2
cicServiceCompliances	1.3.6.1.4.1.9.9.9968.2.1
cicServiceCompliance	1.3.6.1.4.1.9.9.9968.2.1.1			The compliance statement for interfaces which implement the CISCO-IF-CALL-SERVICE-MIB.
cicServiceGroups	1.3.6.1.4.1.9.9.9968.2.2
cicServiceGroup	1.3.6.1.4.1.9.9.9968.2.2.1			A collection of objects for managing per interface basis call service state information.
