Description: Manages Cisco WAN Frame Relay resource partition allocation for multi-controller environments.

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 CISCO-WAN-FR-RSRC-PART-MIB?

CISCO-WAN-FR-RSRC-PART-MIB manages resource partitioning on Frame Relay ports for Cisco WAN switching platforms, allowing logical connection numbers (LCNs) and DLCI (Data Link Connection Identifier) ranges to be allocated among multiple controllers sharing a physical Frame Relay port. It exposes a resource-partition-group table capturing, per port and controller, the number of available LCNs, the low/high DLCI range assigned, and ingress/egress bandwidth percentage allocations. This is primarily a configuration/capacity-monitoring MIB: administrators check available LCN counts to confirm sufficient connection capacity remains for a partition, and ingress/egress bandwidth percentages to verify allocation matches intended service-level agreements per controller. It works alongside the broader Cisco WAN Frame Relay connection/controller MIB family for full port and controller context. It is deployed on Cisco MGX WAN switch platforms running multi-controller Frame Relay port sharing. Engineers can download the CISCO-WAN-FR-RSRC-PART-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-WAN-FR-RSRC-PART-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 MGX WAN switch platform (Frame Relay resource partitioning)

Monitoring Examples

An engineer would poll frPortCnfResPartGrpTable/frPortCnfResPartGrpEntry keyed by frResPartPortNum and frResPartCtrlrNum, checking frResPartNumOfLcnAvail to see if a controller partition is running low on available logical connections before provisioning new PVCs. frResPartDlciLow/frResPartDlciHigh define the DLCI range reserved for that controller, useful when diagnosing a DLCI conflict between partitions. Comparing frResPartIngrPctBW and frResPartEgrPctBW against actual traffic load would reveal whether a partition's configured bandwidth share is being exceeded.

What Can Be Monitored

available LCNs per resource partition
DLCI range per partition
ingress/egress bandwidth percentage allocation
controller-to-port partition mapping

How to Use in IPNetwork Monitor

Example using frResPartNumOfLcnAvail OID:

Select a Cisco MGX WAN switch platform as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type frResPartNumOfLcnAvail into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. This represents number of LCNs available for this controller and this port. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the count changes from its expected baseline, since that would indicate the underlying set of items changed unexpectedly. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoWanFrRsrcPartCompliance	1.3.6.1.4.1.351.150.45.2.1.1			The compliance statement for entities which implement the Frame Relay Resource Partition MIB.
ciscoWanFrRsrcPartGroup	1.3.6.1.4.1.351.150.45.2.2.1			A collection of objects providing the Frame Relay Port resource partition configuration information.
ciscoWanFrRsrcPartMIB	1.3.6.1.4.1.351.150.45			The MIB module to configure the resource partition on Frame Relay Ports. Terminlogies used: LCN : Logical Connection Number. DLCI : Data Link Connection Identifier. A unique number assigned to a PVC endpoint in a frame relay network. This identifies a particular PVC endpoint within a user's access channel in a frame relay network and has local significance only to that channel.
cwfRsrcPartMIBCompliances	1.3.6.1.4.1.351.150.45.2.1
cwfRsrcPartMIBConformance	1.3.6.1.4.1.351.150.45.2
cwfRsrcPartMIBGroups	1.3.6.1.4.1.351.150.45.2.2
frPortCnfResPartGrpEntry	1.3.6.1.4.1.351.110.5.1.1.1.5.1.1		not-accessible	An entry for a resource partition. A resource partition has to be created before connections can be added on a frame relay port.
frPortCnfResPartGrpTable	1.3.6.1.4.1.351.110.5.1.1.1.5.1		not-accessible	This table is for configuring resource partition parameters. A resource partition is configured on frame relay port. The frame relay port if available in ifTable is identified by ifType values frameRelayService(44) and frForward(158).
I32 frResPartCtrlrID	1.3.6.1.4.1.351.110.5.1.1.1.5.1.1.9	Integer32	read-write	This is the controller identifier for the resource patition. The default value is set for PNNI controller. Refer object frResPartCtrlrNum.

The value of this object must be same as the value of 'portNum' from frPortCnfPortGrpTable. If frame relay port is available in ifTable, then the value of this object must be same as the ifIndex value of frame relay ports with ifType frameRelayService(44) and frForward(158).

In MGX Release 2.x: To add an entry, this object should be set to add, value for frResPartCtrlrID may be specified. FRSM will choose default values for all other objects. To delete an entry, this object has to be set to del. Currently the value mod is not supported. The resource partition can be deleted only after deleting all the connections (LCNs).
