TIARA-V35-MIB

Manages Tiara Networks WAN router V.35 serial interface configuration and status.

TIARA-V35-MIB is a vendor-specific SNMP module for Tiara Networks WAN routers covering V.35 serial interface modules, a common physical-layer standard for connecting routers to CSU/DSUs or other WAN termination equipment. It exposes per-interface configuration (clock rate, clock source, operating mode, CRC setting, data mode, flow control) alongside a statistics table reporting alarm status, plus trap definitions for the interface. Its monitoring relevance is interface hardware/link health: v35StatsAlarmStatus reports whether a given V.35 port is currently in an alarm condition (such as loss of carrier or clock), letting an operator detect physical-layer WAN link failures, while the configuration table lets them confirm clocking and flow-control settings match what the connected DTE/DCE equipment expects. It complements standard IF-MIB interface counters by adding V.35-specific physical-layer detail, implying a loose dependency on the interfaces group for ifIndex correlation. It is deployed on Tiara routers with V.35 WAN ports, monitored via polling of alarm status and via subscription to v35Traps for real-time link-state notification. Network engineers evaluating or troubleshooting this functionality can download the TIARA-V35-MIB file directly to load it into their MIB browser.

An operator would poll v35StatsTable's v35StatsAlarmStatus (indexed by v35IfIndex) to detect whether a V.35 serial link has entered an alarm state such as loss of clock or carrier. v35ConfigClockSource and v35ConfigClockRate would be checked against the expected DCE/DTE clocking arrangement if a link is flapping, since a clock-source mismatch is a common cause of V.35 instability. A v35Traps notification with populated v35TrapVariables would alert the NMS the moment the alarm status changes, avoiding the need for continuous polling.
