Description: Manages Cisco Diameter base protocol operations, monitoring peer connections, message statistics, and transport session states.

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-DIAMETER-BASE-PROTOCOL-MIB?

CISCO-DIAMETER-BASE-PROTOCOL-MIB manages entities implementing the Diameter Base Protocol (an AAA protocol used in mobile and broadband networks) on Cisco platforms, based on an early IETF Diameter MIB draft adapted by Cisco. It exposes local Diameter identity configuration, local IP address and TCP listen port tables, and notification enable flags for protocol error, transient/permanent failure, and peer connection up/down events. It directly supports software/protocol status monitoring: the peer-connection-up/down notifications and associated enable flags reveal whether Diameter peer sessions (used for AAA signaling) are currently established or have failed, which is critical for services relying on Diameter for authentication/accounting. It is explicitly based on the IETF draft-zorn-dime-diameter-base-protocol-mib, showing direct standards lineage. It is deployed on Cisco platforms acting as Diameter nodes (e.g., PDSN, gateways) in mobile/broadband AAA infrastructure. Engineers can download the CISCO-DIAMETER-BASE-PROTOCOL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-DIAMETER-BASE-PROTOCOL-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 Diameter-capable network element (e.g., PDSN/AAA gateway)

Monitoring Examples

An admin would check cdbpLocalIpAddrTable, keyed by cdbpLocalIpAddrIndex, to confirm the Diameter node's local IP address and cdbpLocalTcpListenPort are correctly configured for peer connections. Enabling ciscoDiaBaseProtEnablePeerConnectionDownNotif and watching for the corresponding trap reveals when a Diameter peer session unexpectedly drops, which would interrupt AAA transactions. ciscoDiaBaseProtEnableProtocolErrorNotif being triggered indicates malformed or unexpected Diameter messages are being received from a peer.

What Can Be Monitored

  • peer connection up/down events
  • protocol error notifications
  • transient/permanent failure notifications
  • local IP address and TCP listen port configuration

How to Use in IPNetwork Monitor

Example using cdbpLocalStatsTotalPacketsIn OID:

Select a Cisco Diameter-capable network element (e.g. PDSN/AAA gateway) 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 cdbpLocalStatsTotalPacketsIn into the Find box to locate it in the OID tree, then select it and click OK. The total number of packets received by Diameter Base Protocol. 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 Counter32-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 (in packets), 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.
