Description: Manages ATM Multi-Protocol Over ATM (MPOA) client and server functions on Avaya LAN switch platforms.

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.

What Is AVAYA-MPOA-MIB?

AVAYA-MPOA-MIB is an Avaya-specific module implementing Multi-Protocol over ATM (MPOA) per RFC 1483 over AAL5, targeting ATM-based LAN switch and routing platforms in the Avaya/Nortel product line. It is expected to expose configuration and operational objects for MPOA clients (MPCs) and servers (MPSs), including shortcut virtual-circuit setup and protocol state. Monitoring this MIB would let an administrator confirm the operational status of MPOA sessions and shortcut connections, which is central to diagnosing connectivity or performance faults in ATM-to-LAN bridging - effectively a software/protocol-state health check rather than raw hardware telemetry. It complements standard ATM and RFC1483-based MIBs and interoperates with the IF-MIB for underlying interface state. It is deployed in legacy ATM backbone or campus networks where Avaya switches bridge LAN traffic over ATM using MPOA shortcuts, and administrators can download the AVAYA-MPOA-MIB file to load it into their MIB browser when investigating these legacy platforms.

IPNetwork Monitor allows you to monitor SNMP objects defined in AVAYA-MPOA-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.

Avaya/Nortel routing platforms

Monitoring Examples

No sample_objects were supplied for this module, so specific object or table names cannot be cited; the module description only confirms RFC1483/MPOA-over-AAL5 scope. An administrator would typically poll MPC/MPS state and shortcut virtual-circuit tables to detect a stalled or torn-down MPOA shortcut degrading LAN-over-ATM forwarding, but the exact objects are not present in the available data.

What Can Be Monitored

MPOA client status
MPOA server status
shortcut VC state
