Description: DiffServ policy management MIB providing objects to define, apply, and monitor QoS differentiated services policies.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is DIFFSERV-POLICY-MIB?

DIFFSERV-POLICY-MIB is a vendor-neutral IETF standards MIB that provides objects for defining, applying, and monitoring Differentiated Services (DiffServ) QoS policies on network devices. It allows policies to be built from reusable templates that are instantiated into DiffServ datapath configurations and then associated with a specific interface and traffic direction. For monitoring purposes it lets an administrator confirm which QoS policy templates are active on which interfaces and directions, reflecting the state of the device's traffic-classification and queuing software rather than physical hardware health. It is explicitly layered on top of the base DIFFSERV-MIB (the datapath/classifier/queue framework) as a policy-management extension, so it depends on that companion MIB for full context. It is typically deployed on routers and Layer 3 switches in service-provider or enterprise networks that need centralized, template-based QoS policy configuration and verification. Engineers implementing or auditing this functionality typically reference the DIFFSERV-POLICY-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in DIFFSERV-POLICY-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.

routers and Layer 3 switches implementing DiffServ QoS

Monitoring Examples

No specific object or table names were provided in sample_objects for this module, so a concrete instance-level polling example cannot be grounded in real names. Based on the module description, an administrator would generally expect to poll policy-template and interface-association tables to confirm which DiffServ policy is applied to a given interface and direction, and to detect a misapplied or missing policy. Because sample_objects is empty, the specific scalar and table names available in this MIB are not confirmed here.

OIDs

OID symbolic	OID numeric	Type	Access	Description
diffPolicyMib	1.3.6.1.2.1.22222222			This MIB module contains differentiated services specific managed objects to perform policy-based configuration management. This MIB allows policies to use 'templates' to be used to instantiate diffserv datapath configurations to be assigned (associated with an interface and direction) when a policy is created and activated.
diffPolicyMIBObjects	1.3.6.1.2.1.22222222.1
TES diffPolicyDPCUnique	1.3.6.1.2.1.22222222.1.1	TestAndIncr	read-write	The diffPolicyDPCUnique object yields a unique new value for diffPolicyDPCId when read and subsequently set. This value must be tested for uniqueness.
diffPolicyDPCTable	1.3.6.1.2.1.22222222.1.2		not-accessible	A table which defines the various per-hop-behaviors for which the system has default 'templates'.
diffPolicyDPCEntry	1.3.6.1.2.1.22222222.1.2.1		not-accessible	An entry defining a per-hop-behavior. Each entry in this table combines the various parameters (entries) into a specific per-hop-behavior. Entries in this table might be defined by a vendor (pre-configured) or defined by a management application.
I32 diffPolicyDPCId	1.3.6.1.2.1.22222222.1.2.1.1	Integer32	not-accessible	A unique id for the per-hop-behavior policy.
STR diffPolicyDPCDescr	1.3.6.1.2.1.22222222.1.2.1.2	SnmpAdminString	read-create	A human-readable description to identify this defined per-hop-behavior. Note that this is an SnmpAdminString, which permits UTF-8 strings.
STR diffPolicyDPCOwner	1.3.6.1.2.1.22222222.1.2.1.3	SnmpAdminString	read-create	The owner who created this entry.
DAT diffPolicyDPCLastChange	1.3.6.1.2.1.22222222.1.2.1.4	DateAndTime	read-only	The date and time when this entry was last changed.
NUM diffPolicyDPCConfiguration	1.3.6.1.2.1.22222222.1.2.1.5	RowPointer	read-create	The pointer to a datapath configuration template as set up in the DIFFSERV-MIB. This RowPointer should point to an instance of one of: diffServClfrElementEntry diffServClfrEntry diffServMeterEntry diffServActionEntry diffServAlgDropEntry diffServQEntry A value of zeroDotZero in this attribute indicates no further Diffserv treatment is performed on traffic of this datapath. If the row pointed to does not exist, the treatment is as if this attribute contains a value of zero- DotZero.
ROW diffPolicyDPCStatus	1.3.6.1.2.1.22222222.1.2.1.11	RowStatus	read-create	RowStatus object used for creation and deletion of rows in this table.
diffPolicyMIBConformance	1.3.6.1.2.1.22222222.2
diffPolicyMIBCompliances	1.3.6.1.2.1.22222222.2.1
diffPolicyMIBFullCompliance	1.3.6.1.2.1.22222222.2.1.1			The full compliance for this MIB module.
diffPolicyMIBGroups	1.3.6.1.2.1.22222222.2.2
diffPolicyMIBDPCGroup	1.3.6.1.2.1.22222222.2.2.1			The per-hop-behavior Group defines the MIB Objects that describe the configuration template for the per-hop-behavior.
