What Is CISCO-WAN-CES-RSRC-PART-MIB?

CISCO-WAN-CES-RSRC-PART-MIB is a Cisco proprietary MIB for the Circuit Emulation Service (CES) feature on Cisco WAN switching platforms (e.g., the MGX series), used to partition bandwidth resources among multiple controllers sharing a single CES port. It exposes a resource-partition table that defines, per port and controller, the range of logical channel numbers (LCNs) allocated, the number of LCNs available, and the ingress/egress percentage bandwidth assigned to each partition, plus conformance groups for compliance checking. Its monitoring value lies in configuration/resource-allocation status - confirming how bandwidth and channel resources are divided among controllers on a CES port - important for verifying that circuit-emulation capacity has been provisioned as intended and that no partition is starved of LCNs or bandwidth. It is explicitly scoped to Cisco's Circuit Emulation Service feature set and depends on the broader Cisco WAN CES MIB family for the port and controller identifiers it references. It is deployed on Cisco MGX/WAN switching platforms carrying circuit-emulated (TDM-over-packet) traffic in carrier and enterprise WAN networks. Network engineers evaluating or troubleshooting this functionality can download the CISCO-WAN-CES-RSRC-PART-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-WAN-CES-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 switching platform (Circuit Emulation Service module)

Monitoring Examples

An operator can poll cesmPortCnfResPartGrpTable / cesmPortCnfResPartGrpEntry to check cesmResPartLcnLow and cesmResPartLcnHigh against cesmResPartNumOfLcnAvail, confirming that a controller's allocated LCN range fits within the port's available capacity. The cesmResPartIngrPctBW and cesmResPartEgrPctBW objects reveal the ingress/egress bandwidth percentage assigned to each cesmResPartCtrlrID, letting an admin detect an over-committed partition before it causes circuit-emulation service degradation, while cesmResPartRowStatus shows whether a partition entry is actively provisioned.

What Can Be Monitored

LCN range allocation per partition
available LCNs per port
ingress bandwidth percentage
egress bandwidth percentage
partition row status
controller resource assignment

How to Use in IPNetwork Monitor

Example using cesmResPartNumOfLcnAvail OID:

Select a Cisco MGX WAN switching platform (CES module, legacy) 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 cesmResPartNumOfLcnAvail 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.

cesmPortCnfResPartGrpEntry	1.3.6.1.4.1.351.110.5.3.1.2.1.1		not-accessible	An entry for a resource partition. A resource partition have to be created before connections can be added to the logical ports.
cesmPortCnfResPartGrpTable	1.3.6.1.4.1.351.110.5.3.1.2.1		not-accessible	This table is for configuring the resource partition parameters.
