What Is ATM-MIB?
ATM-MIB is an IETF standards-track module defining managed objects for Asynchronous Transfer Mode (ATM) interfaces, virtual path/channel connections (VPCs/VCCs), ATM cross-connects, and AAL5 entities and connections. It belongs to the WAN/carrier transport technology area and is vendor-neutral, covering any device implementing ATM interfaces. It exposes configuration and capacity data through objects like atmInterfaceConfTable/Entry -- including atmInterfaceMaxVpcs, atmInterfaceMaxVccs, atmInterfaceConfVpcs, and atmInterfaceConfVccs -- letting an administrator monitor how many virtual circuits an ATM interface supports versus how many are currently configured, along with addressing objects such as atmInterfaceAddressType and atmInterfaceAdminAddress for interface identity/status. While its primary focus is virtual-connection configuration and capacity rather than deep hardware sensors, it is essential for confirming interface-level connection health and utilization on ATM transport equipment. It depends on the standard Interfaces MIB (IF-MIB) for underlying interface indexing and typically works alongside AAL5-specific counters for cell/frame statistics, and network engineers who load the ATM-MIB MIB module into their management station alongside IF-MIB gain immediate access to the atmInterfaceConfTable objects needed for circuit capacity monitoring. It is deployed in legacy carrier and enterprise WAN environments that still run ATM-based transport (e.g. DSL aggregation backhaul, legacy WAN links).
IPNetwork Monitor allows you to monitor SNMP objects defined in ATM-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.
What Can Be Monitored
- configured VPCs/VCCs per interface
- maximum supported VPCs/VCCs
- active VPI/VCI addressing bits
- ILMI VPI/VCI management channel
- ATM interface administrative address
- ATM cross-connect and AAL5 connection state
Supported Devices
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer
- ATM switches and WAN interface cards
- DSL/ATM aggregation equipment
Monitoring Examples
An administrator polling atmInterfaceConfTable/atmInterfaceConfEntry can compare atmInterfaceConfVpcs and atmInterfaceConfVccs (currently configured virtual paths/channels) against atmInterfaceMaxVpcs and atmInterfaceMaxVccs (interface capacity limits) to detect when an ATM interface is approaching its configured VPC/VCC capacity. Checking atmInterfaceMaxActiveVpiBits and atmInterfaceMaxActiveVciBits reveals the addressing range supported, useful when troubleshooting circuit provisioning failures. atmInterfaceIlmiVpi/Vci identify the ILMI management channel, and atmInterfaceAddressType/atmInterfaceAdminAddress expose the interface's administrative ATM address for connectivity verification.
