What Is TIARA-GENERIC-HDLC-MIB?
TIARA-GENERIC-HDLC-MIB is a Tiara Networks enterprise MIB for configuring and monitoring generic HDLC bundles on Tiara WAN routers. It exposes genHdlcTable for per-interface HDLC configuration (keepalive interval, MTU) and a genHdlcStatsTable of traffic and error counters accumulated since the last boot/clear. It is used to monitor both software and hardware status of WAN links: rising genHdlcStatsErrPktsRxLastBootClear values reveal line-quality problems, while genHdlcStatsUpDownStatesLastBootClear tracks how often the link has flapped, and byte/packet counters show whether the interface is passing expected traffic volume. The module rides on top of the standard interface model (ifIndex/IF-MIB) even though it defines its own HDLC-specific configuration and statistics objects. It is deployed on Tiara Networks WAN routers wherever HDLC-encapsulated serial links are used for site-to-site or access connectivity. Network engineers evaluating or troubleshooting this functionality can download the TIARA-GENERIC-HDLC-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in TIARA-GENERIC-HDLC-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.
What Can Be Monitored
- HDLC keepalive interval
- MTU setting
- bytes/packets transmitted and received since boot
- error packet counts
- link up/down transition counts
Supported Devices
- Tiara Networks WAN router
- HDLC-encapsulated WAN serial interface
Monitoring Examples
An admin would poll genHdlcStatsTable per interface and watch genHdlcStatsErrPktsRxLastBootClear for an increasing count that signals a noisy or misconfigured serial line. genHdlcStatsUpDownStatesLastBootClear climbing quickly would indicate a flapping HDLC link, perhaps from a keepalive mismatch, which could be cross-checked against the configured genHdlcKeepAlive and genHdlcMtu values in genHdlcTable. Comparing genHdlcStatsBytesRxLastBootClear against expected throughput would reveal a link that's up but passing far less traffic than expected.
