What Is VIPTELA-BFD?
VIPTELA-BFD is a vendor MIB from Viptela (now part of Cisco SD-WAN) that models Bidirectional Forwarding Detection (BFD) session state used for fast liveness detection of overlay tunnel paths in an SD-WAN fabric. It exposes summary counters for total, up, max, and flapping BFD sessions, plus a detailed per-session table with source/destination IP, protocol, and port information. Its monitoring value is in tracking the operational health of SD-WAN overlay connectivity — a rising bfdSummaryBfdSessionsFlap count or falling bfdSummaryBfdSessionsUp relative to bfdSummaryBfdSessionsTotal signals path instability or tunnel failures between edge routers. It builds on the IETF BFD protocol model (RFC 5880) though implemented as a Viptela-proprietary data model. It is typically deployed on Viptela/Cisco SD-WAN vEdge/cEdge routers at branch and data-center sites. Engineers can download the VIPTELA-BFD file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in VIPTELA-BFD. 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.
What Can Be Monitored
- total/up/max BFD sessions
- BFD session flap count
- per-session source/destination IP and port
- BFD poll interval
Supported Devices
- Viptela/Cisco SD-WAN vEdge routers
- Viptela/Cisco SD-WAN cEdge routers
Monitoring Examples
An admin polls bfdSummaryBfdSessionsTotal, bfdSummaryBfdSessionsUp, and bfdSummaryBfdSessionsFlap for a fleet-wide view of overlay tunnel liveness, then drills into bfdSessionsListTable/bfdSessionsListEntry to inspect individual sessions by bfdSessionsListSrcIp/bfdSessionsListDstIp and bfdSessionsListProto. A session appearing in the table with a high flap count but not reflected proportionally in bfdSummaryBfdSessionsUp indicates a specific overlay path is intermittently failing, pointing to a WAN link or transport issue between two sites.
