Description: Manages ATM switched virtual circuit routing tables on Ascend ATM equipment.

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.

ASCEND-MIBATMSVCROUTE-MIB is a proprietary Ascend module that manages the routing tables used for ATM switched virtual circuits (SVCs) on Ascend ATM switching equipment. It exposes configuration data describing how SVC setup requests are routed across the switch fabric, rather than raw traffic counters. For monitoring purposes it is used to confirm the software/configuration status of SVC routing — verifying routes are present and correctly prioritized — since a missing or stale route entry causes call/connection setup failures rather than a gradual performance decline. It has no direct tie to an IETF standard MIB, functioning as an Ascend-specific extension to its ATM signaling stack. It is deployed on carrier-grade or enterprise ATM switches handling dynamically signaled SVC traffic. Engineers can download the ASCEND-MIBATMSVCROUTE-MIB file directly to load it into their MIB browser.

This module's sample_objects list was empty, so the scenario is inferred rather than grounded in named objects. An operator would check the SVC route table for the presence and priority of expected routes, and would use failed-connection alarms alongside this table to diagnose why SVCs to a particular destination are being rejected. This is typically monitored alongside ATM interface/port MIBs to correlate signaling failures with underlying link health.
