Description: Manages Frame Relay PVC configuration, LMI, and traffic statistics 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 CXFrameRelay-MIB?

This is a MIB for CX/Memotec devices covering Frame Relay PVC (Permanent Virtual Circuit) configuration, Local Management Interface (LMI) signaling, and traffic statistics. It exposes tables for SAPs, circuits, and reported PVC status, plus a multicast table for Frame Relay multicast group handling, all under a defined MIB level/version indicator. It supports monitoring the operational status and traffic performance of Frame Relay WAN links, tracking which PVCs are reported active via LMI and their associated circuit statistics, functioning as a software/protocol-level health check for the WAN interface carrying the Frame Relay service. It is built on and interoperates with standard Frame Relay DTE/DCE LMI signaling conventions, though implemented as a vendor-specific module. It is deployed on CX Memotec Frame Relay access devices/multiplexers used to connect branch offices over legacy Frame Relay WAN circuits, where administrators monitor PVC status tables to detect circuit or LMI-reporting problems. Engineers can download the CXFrameRelay-MIB file directly to load it into their MIB browser.

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

  • CX Memotec Frame Relay access device/multiplexer

Monitoring Examples

An operator polls frpReportedPvcTable to see which PVCs the LMI protocol has reported as active or down, cross-referencing entries in frpCircuitTable for circuit-level traffic counters and frpSapTable for the SAP-level configuration each PVC runs over. A PVC that disappears from frpReportedPvcTable while its underlying physical interface stays up would indicate an LMI/DLCI-level Frame Relay signaling problem rather than a physical link failure; frpMulticastTable would additionally be checked if multicast DLCI groups are configured, and frpMibLevel identifies the MIB/firmware capability level in use on the device.

What Can Be Monitored

  • PVC/DLCI status
  • LMI reporting state
  • circuit traffic statistics
  • multicast group configuration
  • MIB/firmware level
