This section documents the following modified command:
To display temperature, voltage, fan, and power supply information on the Cisco 7000 series, Cisco 7200 series, NPE-G2 in Cisco 7200 VXR routers, Cisco 7304 routers, Cisco 7500 series routers, Cisco 3600 series routers, Cisco AS5300 series access servers, and Cisco 12000 series Gigabit Switch Routers (GSRs), use the show environment command in user EXEC or privileged EXEC mode.
show environment [alarms | all | fans | hardware | last | leds | power-supply | table | temperature | voltages]
On the Cisco 7000 Series, Cisco 7200 Series, Cisco 7304, and Cisco 7500 Series Routers
show environment [all | last | table]
If no options are specified, the default is all.
The availability of keywords will depend on your system and platform. The command does not support SPAs on the Cisco 7200 series and on the NPE-G2 in the Cisco 7200 VXR routers.
A routine runs once a minute that reads environmental measurements from sensors and stores the output into a buffer. For shared port adapters (SPAs), the temperature and voltage sensors are read every few seconds to get environmental data. The environmental buffer is displayed on the console when you use the show environment command.
If a measurement exceeds desired margins, but has not exceeded fatal margins, a warning message is printed to the system console. The system software queries the sensors for measurements once a minute, but warnings for a given test point are printed at most once every hour for sensor readings in the warning range and once every 5 minutes for sensor readings in the critical range. If a measurement is out of line within these time segments, an automatic warning message appears on the console. As noted, you can query the environmental status with the show environment command at any time to determine whether a measurement is at the warning or critical tolerance.
A SPA is shut down when any of the SPA environment readings exceed the shutdown threshold.
If a shutdown occurs because of detection of fatal environmental margins, the last measured value from each sensor is stored in internal nonvolatile memory.
For environmental specifications, refer to the hardware installation and configuration publication for your individual chassis.
For network processor engines (NPEs), network services engines (NSEs), line cards, and modular services cards (MSCs), environmental information is recorded in the CISCO-ENVMON-MIB. SPAs are not supported by the CISCO-ENVMON-MIB. In Cisco IOS Release 12.2(20)S2 and later, the CISCO-ENTITY-SENSOR-MIB supports environmental information for SPAs, as well as NPEs, NSEs, line cards, and MSCs.
If the Cisco 12000 series GSR exceeds environmental conditions, a message similar to the following is displayed on the console:%GSR_ENV-2-WARNING: Slot 3 Hot Sensor Temperature exceeds 40 deg C;Check cooling systems
Note Blower temperatures that exceed environmental conditions do not generate a warning message.
You can also enable Simple Network Management Protocol (SNMP) notifications (traps or informs) to alert a network management system (NMS) when environmental thresholds are reached using the snmp-server enable traps envmon and snmp-server host global configuration commands.
Whenever Cisco IOS software detects a failure or recovery event from the DRPS unit, it sends an SNMP trap to the configured SNMP server. Unlike console messages, only one SNMP trap is sent when the failure event is first detected. Another trap is sent when the recovery is detected.
Cisco AS5300 DRPS software reuses the MIB attributes and traps defined in CISCO-ENVMON-MIB and CISCO-ACCESS-ENVMON-MIB. CISCO-ENVMON-MIB is supported by all Cisco routers with RPS units, and CISCO-ACCESS-ENVMON-MIB is supported by the Cisco 3600 series routers.
A power supply trap defined in CISCO-ENVMON-MIB is sent when a failure is detected and when a failure recovery occurs for the following events: input voltage fail, DC output voltage fail, thermal fail, and multiple failure events.
A fan failure trap defined in CISCO-ENVMON-MIB is sent when a fan failure or recovery event is detected by Cisco IOS software.
A temperature trap defined in CISCO-ACCESS-ENVMON-MIB is sent when a board over-temperature condition is detected by Cisco IOS software.
CISCO-ACCESS-ENVMON-MIB also defines an over-voltage trap. A similar trap is defined in CISCO-ENVMON-MIB, but it requires the ciscoEnvMonVoltageStatusValue in varbinds. This value indicates the current value of the voltage in the RPS. With Cisco AS5300 RPS units, the current voltage value is not sent to the motherboard.
CISCO-ENVMON-MIB is extended to add a new enumerated value, internalRedundant(5), for MIB attribute ciscoEnvMonSupplySource. This is used to identify a RPS unit.
In the following example, the typical show environment display is shown when no warning conditions are in the system for the Cisco 7000 series and Cisco 7200 series routers. This information may vary slightly depending on the platform you are using. The date and time of the query are displayed, along with the data refresh information and a message indicating that there are no warning conditions.Router> show environmentEnvironmental StatisticsEnvironmental status as of 13:17:39 UTC Thu Jun 6 1996Data is 7 second(s) old, refresh in 53 second(s)All Environmental Measurements are within specifications

NPE-G2 in Cisco 7200 VXR Routers Examples
In the following example, additional temperature and voltage readings for the NPE-G2 in the Cisco 7200 VXR router are displayed by the show environment all command. Power supplies 1 and 2 are on, and all monitored variables are within the normal operating range.Router_npe-g2# show environment allPower Supplies:Power Supply 1 is Zytek AC Power Supply.

In the following example, the show environment last command displays the previously saved measurements (readings) from the last environmental reading before the router was shut down. The command also displays the reason why the router was shut down, which was "power supply shutdown" in this case.Router_npe-g2# show environment lastNPE Inlet previously measured at 26C/78FNPE Outlet previously measured at 28C/82FCPU Die previously measured at 56C/132F+3.30 V previously measured at +3.32+1.50 V previously measured at +1.48+2.50 V previously measured at +2.46+1.80 V previously measured at +1.75+1.20 V previously measured at +1.17VDD_CPU previously measured at +1.28VDD_MEM previously measured at +2.50VTT previously measured at +1.25+3.45 V previously measured at +3.39-11.95 previously measured at -11.93+5.15 V previously measured at +4.96+12.15 V previously measured at +12.18last shutdown reason - power supply shutdownRouter_npe-g2#
In the following example, the show environment table command displays threshold levels in a table format of the environmental monitor parameters. It displays the high warning, high critical, and high shutdown temperature thresholds of the NPE inlet, NPE outlet, and CPU Die. It also displays the low and high critical voltage thresholds, and low and high shut down voltage thresholds for the power rails on the NPE-G2 in the Cisco 7200 VXR.
Note The low range temperatures, such as the LowShut, LowCrit, and LowWarn temperature thresholds, are not checked and are not displayed on the NPE-G2. Also the warning voltage thresholds, such as LowWarn and HighWarn, are not checked and are not displayed on the NPE-G2.

The following examples are for the Cisco 12000 series GSRs.
The following is sample output from the show environment command for a Cisco 12012 router. Slots 0 through 11 are the line cards, slots 16 and 17 are the clock and scheduler cards, slots 18 through 20 are the switch fabric cards, slots 24 through 26 are the power supplies, and slots 28 and 29 are the blowers. An "NA" in the table means that no values were returned. In some cases it is because the equipment is not supported for that environmental parameter (for example, the power supply and blowers in slots 24, 26, 28, and 29 do not have a 3V power supply, so an NA is displayed).Router# show environmentSlot # 3V 5V MBUS 5V Hot Sensor Inlet Sensor(mv) (mv) (mv) (deg C) (deg C)0 3300 4992 5040 42.0 37.02 3296 4976 5136 40.0 33.04 3280 4992 5120 38.5 31.57 3280 4984 5136 42.0 32.09 3292 4968 5160 39.5 31.511 3288 4992 5152 40.0 30.516 3308 NA 5056 42.5 38.017 3292 NA 5056 40.5 36.518 3304 NA 5176 36.5 35.019 3300 NA 5184 37.5 33.520 3304 NA 5168 36.5 34.024 NA 5536 5120 NA 31.526 NA 5544 5128 NA 31.528 NA NA 5128 NA NA29 NA NA 5104 NA NASlot # 48V AMP_48(Volt) (Amp)24 46 1226 46 19Slot # Fan 0 Fan 1 Fan 2(RPM) (RPM) (RPM)28 2160 2190 216029 2130 2190 2070Router#
