Description: Provides temporary BFD session management objects for Nortel Ethernet Routing Switch platforms pending IETF standardization.

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 RC-BFD-TMP-MIB?

RC-BFD-TMP-MIB is a Nortel Networks (Rapid-City/Ethernet Routing Switch) enterprise MIB that provides an early, pre-standard implementation of Bidirectional Forwarding Detection (BFD) session management, based on an IETF BFD MIB draft (draft-ietf-bfd-mib-03) with vendor-specific object names/OIDs. It exposes BFD session state, discriminators, diagnostics, and administrative status through a session table, along with global admin-status and version scalars. This MIB is fundamentally a fault-detection/availability monitoring tool: it lets operators track whether fast-failure-detection sessions between routers are up, down, or flapping, which is critical for detecting link or neighbor failures far faster than routing protocol timers alone. It is explicitly a temporary, vendor-named duplicate of the IETF's draft BFD MIB, intended to be replaced once that standard matured. It is deployed on Nortel Ethernet Routing Switch platforms running dynamic routing protocols (e.g., OSPF, IS-IS, BGP) that rely on BFD for sub-second failure detection between adjacent routers. Engineers can download the RC-BFD-TMP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RC-BFD-TMP-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

  • Nortel Ethernet Routing Switch

Monitoring Examples

An engineer would poll rcBfdTmpSessTable (rcBfdTmpSessEntry) for rcBfdTmpSessState and rcBfdTmpSessDiag on each session to confirm BFD sessions remain in the 'Up' state between routing peers. A transition of rcBfdTmpSessState to 'Down' combined with a non-zero rcBfdTmpSessDiag value would indicate a fast-detected link or peer failure, while rcBfdTmpSessDiscriminator/rcBfdTmpSessRemoteDiscr help correlate local and remote session identifiers during troubleshooting. rcBfdTmpAdminStatus confirms whether BFD is administratively enabled on the device at all.

What Can Be Monitored

  • BFD session state
  • BFD session diagnostics
  • local/remote discriminators
  • BFD administrative status

How to Use in IPNetwork Monitor

Example using rcBfdTmpSessPerfPktInHC OID:

Select a Nortel Ethernet Routing Switch (pre-standard Bidirectional Forwarding Detection sessions) 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 rcBfdTmpSessPerfPktInHC into the Find box to locate it in the OID tree, then select it and click OK. This value represents the total number of BFD messages received for this BFD session. 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.
