What Is CXBOPIO-MIB?

CXBOPIO-MIB is a vendor-specific MIB from Aastra (formerly Memotec/ConvertedX) covering the BOP (Bit-Oriented Protocol) I/O module used on CX-series WAN access equipment. It exposes configuration and operational-state data for BOP ports, including clock source selection, data encoding, and idle-line conditioning used in framed/synchronous WAN links. In monitoring terms it is used chiefly for hardware/software status of the module: it lets an operator confirm the administrative versus operational settings of each BOP port are in sync and detect misconfiguration (e.g., clock source mismatches) that would cause line framing errors or loss of synchronization. It works alongside other Aastra CX enterprise MIBs (such as CXLapBD-MIB and CXISDN-MIB) that manage adjacent WAN protocol layers on the same chassis. It is typically deployed in legacy telecom/WAN access gear at branch offices or telco POPs, where the CXBOPIO-MIB MIB remains in use for monitoring bit-oriented synchronous framing on BOP ports.

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

  • Aastra ConvertedX (CX) WAN access router
  • Aastra BOP I/O interface module

Monitoring Examples

An administrator would poll bopSapOprTable and its columnar object bopSapOprPortClockSource alongside the corresponding entries in bopSapAdmTable to verify that the operational clock source matches the administratively configured one; a mismatch often indicates a misprovisioned port. bopSapOprPortDataEncoding and bopSapOprPortIdleCondition would be checked to confirm the line encoding and idle-fill pattern are correct for the attached circuit, since a wrong idle condition setting can cause the far end to see spurious framing errors. bopMibLevel is read once to determine which version of the MIB's object set the agent supports before polling further.

What Can Be Monitored

  • BOP port clock source (admin vs operational)
  • port data encoding
  • line idle condition
  • administrative vs operational port table state
  • MIB support level
