What Is Wellfleet-HSSI-MIB?

Wellfleet-HSSI-MIB is a vendor-specific MIB from Wellfleet Communications that models High-Speed Serial Interface (HSSI) line configuration and statistics on Wellfleet routers. Its single table, wfHssiTable, indexed by wfHssiSlot and wfHssiConnector, covers line provisioning (wfHssiMtu, wfHssiWanProtocol — standard/PPP/Frame Relay/SMDS/ATM/switch, wfHssiTransmissionInterface for T1 vs T3, wfHssiExternalClkSpeed, wfHssiCrcSize) and operational state (wfHssiState: up/lmiwait/boflwait/init/loopback modes/not-present), alongside a large set of counter objects for traffic and fault statistics — wfHssiRxOctets/Frames and wfHssiTxOctets/Frames for throughput, wfHssiInDiscards/InErrors/OutDiscards/OutErrors for delivery failures, and lower-level fault counters like wfHssiRxCrcErrors, wfHssiRxOverruns, wfHssiRxAborts, wfHssiTxUnderruns, and ring/host/internal operation error counters. It also exposes performance-tuning parameters (buffer length, ring length, FIFO watermarks) and loopback control (wfHssiLoopback). Because HSSI links typically carry high-speed WAN trunk traffic, monitoring these per-line error and discard counters is important for catching clocking problems, cable faults, or congestion before they cause outages, and it is deployed alongside Wellfleet-COMMON-MIB (from which it imports wfLine) on Wellfleet routers equipped with HSSI interface modules. Engineers can perform a Wellfleet-HSSI-MIB download to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Wellfleet-HSSI-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.

Wellfleet routers with HSSI (High-Speed Serial Interface) modules

Monitoring Examples

An operator polls wfHssiTable to check wfHssiRxCrcErrors and wfHssiRxOverruns against wfHssiRxFrames for a given slot/connector; a rising ratio of CRC errors or overruns to good frames would indicate a clocking mismatch or cabling problem on that HSSI trunk.

What Can Be Monitored

per-line receive/transmit octet and frame counters
receive/transmit discard and error counters
CRC errors, overruns, and abort counters
line operational state and loopback mode
ring/host/internal operation error events
buffer, ring-length, and FIFO watermark tuning parameters
