Description: Manages Common Public Radio Interface (CPRI) links on Cisco radio access equipment, monitoring link status and fronthaul performance.

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-CPRI-MIB?

CISCO-CPRI-MIB is a Cisco proprietary MIB for the Common Public Radio Interface (CPRI), the fronthaul link technology connecting baseband units to remote radio heads in mobile/radio-access equipment. It exposes physical-layer link configuration and status: supported and configured line rates, negotiated rate, port role, admin and operational status, loopback state, alarm status and Radio-over-Ethernet (RoE) statistics. It is strongly oriented toward monitoring hardware link health — operational/admin status and alarm status directly reveal fronthaul link faults or signal degradation, and a mismatch between negotiated and configured rate signals a physical-layer problem. It follows the industry CPRI specification and mirrors the familiar admin/operational-status pattern used across standard interface MIBs. It is deployed in Cisco mobile fronthaul and RAN aggregation equipment connecting cell-site radio equipment. Engineers can download the CISCO-CPRI-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-CPRI-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 mobile fronthaul / RAN aggregation equipment (CPRI-capable radio access nodes)

Monitoring Examples

coiCpriControllerTable/coiCpriControllerEntry provides per-controller status: coiCpriControllerOperStatus and coiCpriControllerAdminStatus reveal whether a fronthaul link is up, while coiCpriControllerAlarmStatus flags degraded signal or synchronization loss. A mismatch between coiCpriControllerNegotiatedRate and coiCpriControllerConfiguredRateList indicates the link negotiated down from its intended rate, and coiCpriControllerLoopbackInfo would show the link stuck in a test/loopback state instead of carrying traffic.

What Can Be Monitored

CPRI link admin/operational status
negotiated vs configured link rate
alarm status
loopback mode
port role (master/slave)

How to Use in IPNetwork Monitor

Example using coiCpriRoeRxFrames OID:

Select a Cisco mobile fronthaul / RAN aggregation equipment (CPRI) 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 coiCpriRoeRxFrames 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 object gives the number of RoE frames received. 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 a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
