Description: Manages Frame Relay to ATM interworking function (IWF) configuration on CX Memotec devices.

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 CXFrameRelayATMIWF-MIB?

CXFrameRelayATMIWF-MIB is a legacy Crosscomm (CX900/CX1000 architecture, built on CXProduct-SMI) proprietary MIB managing Frame Relay/ATM Interworking Function (IWF). Its objects cover a MIB-level version and a connect timer, plus an NI (Network Interworking) SAP table (number, state, failure reason, DE-to-CLP and CLP-to-DE mapping mode, CLP bit setting). As a configuration/status MIB it lets an administrator confirm DE/CLP bit-mapping and SAP state for Frame Relay/ATM interworking on a legacy Crosscomm CX router. It is deployed on legacy Crosscomm CX900/CX1000 router equipment (Frame Relay/ATM interworking). Engineers can download the CXFrameRelayATMIWF-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CXFrameRelayATMIWF-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

  • Legacy Crosscomm CX900/CX1000 router equipment (Frame Relay/ATM interworking)

Monitoring Examples

An administrator checks frpAtmNISapState and frpAtmNISapDEtoCLPMapping to confirm Frame Relay/ATM interworking SAP state and bit-mapping on a legacy Crosscomm CX router.

What Can Be Monitored

  • Frame Relay/ATM interworking SAP state and DE/CLP bit mapping
