What Is BSC2780-OPT-MIB?

BSC2780-OPT-MIB is a legacy vendor MIB (associated with Cabletron/CDX-branded hardware given its cdx6500-prefixed objects) for configuring Binary Synchronous Communication (BSC) 2780 protocol options, a legacy protocol used for Remote Job Entry (RJE) terminal emulation over serial WAN links. It exposes configuration groups for BSC protocol behavior on specific port types (PCT and PST ports on a CDX 6500-series device). As a small, narrowly-scoped options MIB, its monitoring role is limited to confirming the BSC protocol configuration applied to a given serial port matches what's expected, rather than exposing hardware sensors or performance counters -- useful mainly for verifying legacy RJE terminal connectivity settings are correctly provisioned. It is tied to the specific CDX 6500 chassis/port architecture rather than any IETF standard. It would be found in legacy mainframe-connectivity environments still running BSC-based RJE links to a CDX 6500 communications server. Engineers can download the BSC2780-OPT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BSC2780-OPT-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.

Monitoring Examples

An administrator would check cdx6500PCTPortProtocolGroup or cdx6500PSTPortProtocolGroup on a specific port to confirm the BSC 2780 protocol options configured for that port match the terminal or host system it connects to. A mismatch here would explain a legacy RJE session failing to establish or garbled data on that serial link.
