What Is CISCO-CBP-TARGET-MIB?

CISCO-CBP-TARGET-MIB is a Cisco module in the Class-Based Policy (CBP) technology area, managing the association of policy definitions to logical interface targets on Cisco devices. It exposes configuration data identifying each policy target (interface type, direction, and identifier) and which policy map or instance is attached to it. This is relevant to monitoring the software configuration status of policy attachments on a device, since an admin can verify which policy (via ccbptPolicyMap/ccbptPolicyInstance) is bound to which target and direction, and detect targets left without an expected policy or attached to the wrong one. It explicitly depends on companion Cisco CBP MIBs (such as CISCO-CBP-TC-MIB for shared textual conventions and likely CISCO-CBP-BASE-CFG-MIB/CISCO-CBP-BASE-MON-MIB for the policies themselves) for full context. It is deployed on Cisco routers/switches implementing class-based policy frameworks for traffic classification and treatment, where CISCO-CBP-TARGET-MIB SNMP monitoring confirms the correct policy stays bound to each target.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-CBP-TARGET-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 routers and switches implementing Class-Based Policy

Monitoring Examples

An admin would poll ccbptTargetTable (via ccbptTargetEntry) for a given ccbptTargetId and ccbptTargetType to check ccbptTargetDir (direction) alongside ccbptPolicyMap and ccbptPolicyInstance, confirming the correct policy is bound in the correct direction on that target. ccbptTargetStatus and ccbptTargetStorageType reveal whether a target-policy binding is active and how it persists across reloads. An unexpectedly absent or mismatched ccbptPolicyId for a target that should have an active policy would indicate a configuration gap causing traffic to bypass intended class-based treatment; ciscoCbpTargetMIBNotifs would signal related changes.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoCbpTargetMIB	1.3.6.1.4.1.9.9.533			This MIB module defines the managed objects for representing targets which have class-based policy mappings. A target can be any logical interface to which a class-based policy is able to be associated.
ciscoCbpTargetMIBNotifs	1.3.6.1.4.1.9.9.533.0
ciscoCbpTargetMIBObjects	1.3.6.1.4.1.9.9.533.1
ccbptTargetAttachCfg	1.3.6.1.4.1.9.9.533.1.1
OID ccbptPolicyIdNext	1.3.6.1.4.1.9.9.533.1.1.1	CcbptPolicyIdentifierOrZero	read-only	This object indicates the next available value of ccbptPolicyId that can be used to create a new conceptual row in the ccbptTargetTable. If no available identifier exists, then this object will have the value '0'.
ccbptTargetTable	1.3.6.1.4.1.9.9.533.1.1.2		not-accessible	This table describes the class-based policy attachments to to specific targets.
ccbptTargetEntry	1.3.6.1.4.1.9.9.533.1.1.2.1		not-accessible	Each entry describes a class-based policy attachment to a particular target. The ccbptTargetType uniquely identifies the type of target in the attachment. Additionally, the ccbptTargetId uniquely identifies the target in attachment and is of the format indicated by the ccbptTargetType. The ccbptTargetDir identifies the direction, relative to the ccbptTargetId, to which the policy is attached. The ccbptPolicySourceType identifies the source-type of the policy attached. The ccbptPolicyId uniquely identifies the policy within the scope of ccbptTargetType, ccbptTargetId, ccbptTargetDir, and ccbptPolicySourceType. A class-based policy attachment to a target can be created through other network management interfaces (e.g., the local console), in which case the SNMP entity will automatically create an entry in this table. A class-based policy attachment to a target can be destroyed through other network management interfaces, in which case the SNMP entity will automatically destroy the corresponding entry in this table. A class-based policy attachment to a target can be created, destroyed, and modified through the SNMP using ccbptTargetStatus using the semantics described by the RowStatus Textual Convention. However, when creating a new class-based policy attachment to a target, the value of ccbptPolicyIdNext should be used to identify the new policy within the scope of the target type, identifier, direction, and policy-source type.
CCB ccbptTargetType	1.3.6.1.4.1.9.9.533.1.1.2.1.1	CcbptTargetType	not-accessible	The type of target for this class-based policy attachment. This object identifies the format of the ccbptTargetId for this entry.
CCB ccbptTargetId	1.3.6.1.4.1.9.9.533.1.1.2.1.2	CcbptTargetId	not-accessible	The target identifier for this class-based policy attachment. For decoding the ccbptTargetId refer to the ccbptTargetType object and the CcbptTargetType description.
CCB ccbptTargetDir	1.3.6.1.4.1.9.9.533.1.1.2.1.3	CcbptTargetDirection	not-accessible	The direction relative to the ccbptTargetId for this class based policy attachment.
CCB ccbptPolicySourceType	1.3.6.1.4.1.9.9.533.1.1.2.1.4	CcbptPolicySourceType	not-accessible	The source-type of the class-based policy for this target. The source-type refers to the source of the class-based policy definition. The intent of this object is to allow implementations to distinguish between different MIBs defining policy-maps.
OID ccbptPolicyId	1.3.6.1.4.1.9.9.533.1.1.2.1.5	CcbptPolicyIdentifier	not-accessible	Unique identifier of this class-based policy instance.
ROW ccbptTargetStatus	1.3.6.1.4.1.9.9.533.1.1.2.1.6	RowStatus	read-create	The status of the policy attachment to this target. The value for the corresponding instance of each of the following objects must be valid before the attachment can be activated: -ccbptTargetStorageType -ccbptPolicyMap Observe that no corresponding instance of any object in this table can be modified when the value of this object is 'active'.
STO ccbptTargetStorageType	1.3.6.1.4.1.9.9.533.1.1.2.1.7	StorageType	read-create	This object indicates how the device stores the data contained by the conceptual row. If an instance of this object has the value 'permanent', then this MIB definition does not require the SNMP entity to allow the instance of any object in the corresponding conceptual row to be writable through the SNMP.
NUM ccbptPolicyMap	1.3.6.1.4.1.9.9.533.1.1.2.1.8	RowPointer	read-create	Refers to the first accessible object in the policy-map definition table used to manage policy-map information for policy-maps for the corresponding ccbptPolicySourceType. Specific MIB tables are not mentioned here as the intent of this mapping is to allow for different implementations to refer to their supported class-based policy definition table without requiring support of a specific MIB module.
NUM ccbptPolicyInstance	1.3.6.1.4.1.9.9.533.1.1.2.1.9	RowPointer	read-only	Refers to the first accessible object in the policy instance table used to manage policy instance information for policy-maps of this ccbptPolicySourceType. Specific MIB tables are not mentioned here as the intent of this mapping is to allow for different implementations to refer to their supported class-based policy definition table without requiring support of a specific MIB module.
TIM ccbptPolicyAttachTime	1.3.6.1.4.1.9.9.533.1.1.2.1.10	TimeStamp	read-only	The value of sysUpTime for the last time that the corresponding ccbptTargetStatus instance transitioned to the 'active' state.
TIM ccbptTargetTableLastChange	1.3.6.1.4.1.9.9.533.1.1.3	TimeStamp	read-only	The value of sysUpTime at the time of the last change to an entry in the ccbptTargetTable.
ciscoCbpTargetMIBConform	1.3.6.1.4.1.9.9.533.2
ciscoCbpTargetMIBCompliances	1.3.6.1.4.1.9.9.533.2.1
ciscoCbpTargetMIBCompliance	1.3.6.1.4.1.9.9.533.2.1.1			The compliance statement for SNMP entities that implement the CISCO-CBP-TARGET-MIB. Implementation of this MIB module is strongly recommended for any devices implementing features using class-based policies, such as QoS, NAT, firewall, and MTR (Multi-Topology Routing).
ciscoCbpTargetMIBMIBGroups	1.3.6.1.4.1.9.9.533.2.2
ccbptTargetProvisioningGroup	1.3.6.1.4.1.9.9.533.2.2.1			A collection of managed objects describing the target and class-based policy attachment configuration data.
ccbptTargetTimeGroup	1.3.6.1.4.1.9.9.533.2.2.2			A collection of managed objects describing the target and class-based policy attachment timestamp data.
