What Is OLD-CISCO-ENV-MIB?

OLD-CISCO-ENV-MIB is a legacy Cisco enterprise MIB providing environmental monitoring objects -- temperature and voltage readings -- for early Cisco IOS-based routers and switches, predating Cisco's later, more comprehensive CISCO-ENVMON-MIB. No object names were supplied in this batch, but by design such legacy environmental MIBs expose per-component temperature test points and power supply voltage status for the chassis. Its entire purpose is hardware status monitoring: detecting an overheating chassis or a failing power supply/voltage rail before it causes a device outage, on devices where more modern entity-based environmental MIBs are not available. It is superseded by (and has no formal dependency on) later standard MIBs like ENTITY-MIB or CISCO-ENVMON-MIB, existing purely as Cisco's early proprietary implementation. It is deployed on older Cisco IOS routers/switches that only support the legacy environmental object set. Engineers can download the OLD-CISCO-ENV-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in OLD-CISCO-ENV-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

chassis temperature
power supply voltage status

Supported Devices

legacy Cisco IOS router/switch (early platforms)

Monitoring Examples

An operator would poll the legacy temperature and voltage-status objects (per the module's naming convention) to confirm the chassis is running within its normal thermal and power envelope. A temperature reading crossing its warning or critical threshold, or a voltage status object reporting other than "normal," would indicate an environmental fault requiring physical inspection of the device's cooling or power supply. Because no object names were available in this batch, exact object names cannot be confirmed and this description reflects the module's known general purpose.
