What Is ATM-FORUM-MIB?
ATM-FORUM-MIB is a vendor-neutral, standards-based MIB defined by the ATM Forum industry consortium for managing ATM network interfaces, ports, and virtual circuits across compliant equipment from any manufacturer. It exposes objects covering physical/logical ATM port identity and addressing, transmission and media type, operational status, and mappings to IP/OSI network-management addresses used to reach the device. Its monitoring value is primarily interface and connectivity health: administrators poll atmfPortOperStatus to detect a down ATM port and cross-reference atmfPortTransmissionType/atmfPortMediaType against expected configuration to catch a cabling or media mismatch, while the NSAP/IP address objects support network-layer reachability checks rather than deep hardware sensor data. As the baseline ATM Forum standard, it is commonly extended or paralleled by vendor-specific MIBs (such as ATM-ADAPTER-MIB) that add hardware-specific detail on top of these standard objects. It is deployed across any ATM-capable switch, router, or adapter historically used in carrier and enterprise ATM backbone networks. Engineers can download the ATM-FORUM-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ATM-FORUM-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.
Supported Devices
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer — applies to any ATM-capable switch, router, or network adapter
Monitoring Examples
An operator would poll atmfPortTable/atmfPortEntry rows by atmfPortIndex, checking atmfPortOperStatus for each ATM port and comparing atmfPortAddress and atmfMyIpNmAddress/atmfMyOsiNmNsapAddress to confirm correct network-management addressing. A port reporting atmfPortOperStatus as down while atmfPortMyIfName still shows it as the expected uplink interface would flag an unexpected ATM link failure needing investigation.
What Can Be Monitored
- ATM port operational status
- port transmission type
- port media type
- port network-management addressing (IP/NSAP)
- port index/identity mapping to interface
