What Is OLD-CISCO-SYSTEM-MIB?
This is a legacy, pre-standard Cisco proprietary MIB that predates the later CISCO-SYSTEM-MIB and RFC-standard SNMPv2-MIB/ENTITY-MIB, originally used to expose basic Cisco IOS device identity and system objects on very early Cisco routers. No object list was captured from this MIB's source in the provided data, but modules of this era and name typically exposed scalar chassis identification, IOS software version, and configuration-register-style objects. Where still supported, its monitoring role is fundamentally software/hardware identity reporting -- confirming IOS version and system identity -- rather than the richer performance or environmental monitoring found in later Cisco MIBs. It exists as a superseded module tied to Cisco's own legacy SNMP object tree conventions rather than IETF standards. It would only be encountered on very old, no-longer-maintained Cisco IOS router/switch platforms retained for historical MIB compatibility, and administrators researching such legacy equipment can still download the OLD-CISCO-SYSTEM-MIB file for reference.
IPNetwork Monitor allows you to monitor SNMP objects defined in OLD-CISCO-SYSTEM-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
- system identity/chassis information
- software version
- basic system configuration
Supported Devices
- legacy Cisco IOS router/switch (early-generation, no longer produced)
Monitoring Examples
No sample objects were available for this MIB in the provided source, so no specific table or object names can be cited; this appears to be a legacy scalar-identity module rather than a rich runtime data MIB. Historically, modules of this name exposed simple system identification scalars rather than tables, and were superseded by CISCO-SYSTEM-MIB and standard MIB-II/ENTITY-MIB objects for equivalent information. An operator encountering this MIB today would most likely be dealing with archived management-station configuration for a decommissioned router rather than active monitoring.
