USR-ATM-1577-PVC-MIB

Description: Manages RFC 1577 Classical IP over ATM PVC configuration and ARP resolution parameters.

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.

USR-ATM-1577-PVC-MIB is a vendor MIB (US Robotics/CommWorks/3Com lineage) implementing management objects for RFC 1577 Classical IP over ATM, focused on Permanent Virtual Circuit (PVC) configuration and the associated ATM ARP resolution used to map IP addresses to ATM addresses. It exposes configuration-oriented data about PVC endpoints and ARP table entries rather than general hardware telemetry. Its monitoring value is largely software/configuration status: confirming that a PVC is correctly provisioned and that ATM ARP entries are resolving IP-to-ATM address mappings correctly, which is essential for diagnosing connectivity failures on a Classical IP over ATM link. It directly depends on and extends RFC 1577 (Classical IP and ARP over ATM), inheriting its ARP resolution model. It is deployed on legacy ATM-based WAN access equipment, such as USR/3Com ATM edge or access routers, in networks still using Classical IP over ATM PVCs. Engineers can download the USR-ATM-1577-PVC-MIB file directly to load it into their MIB browser.

No sample object names were provided for this module in the source data; based on its stated purpose, one would expect a PVC configuration table keyed by ATM interface/VPI-VCI and an ARP resolution table mapping IP addresses to ATM addresses per RFC 1577. An operator would poll such tables to confirm a PVC is up and that the expected IP-to-ATM ARP mapping exists, which would explain a host being unreachable if the ARP entry is missing or stale.
