Command History

Release
Modification

10.0

This command was introduced.

11.2 GS

The alarms, fans, hardware, leds, power-supply, table, temperature, and voltages keywords were added for the Cisco 12000 series GSRs.

11.3(6)AA

This command was expanded to monitor the RPS and board temperature for the Cisco AS5300 platform, Cisco 3600 Series routers, Cisco 7200 series routers, and the Cisco 12000 series GSRs.

12.2(20)S

This command was integrated into Cisco IOS Release 12.2(20)S.

12.2(20)S2

This command was integrated into Cisco IOS Release 12.2(20)S to support MSCs and SPAs on the Cisco 7304 router using the all, last, and table keywords.

12.4(4)XD

This command was integrated into Cisco IOS Release 12.4(4)XD to support the NPE-G2 on the Cisco 7200 VXR using the all, last, and table keywords. Command output was modified for the NPE-G2.


Usage Guidelines

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.

Examples

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.

Table 4 show environment table Field Descriptions for the NPE-G2 in Cisco 7200 VXR Router 

Field
Description

Sample Point

This is the area for which temperature or system voltage thresholds are displayed.

LowShut

This is the LowShut voltage threshold. If the voltage value is below the LowShut threshold, the router shuts down.

Note The LowShut temperature value is not checked and its threshold is not displayed on the NPE-G2.

LowCrit

This is the low critical voltage threshold. If the voltage value is below the LowCrit threshold, a critical message is issued for an out-of-tolerance voltage value. The system continues to operate. However, the system is approaching shutdown.

Note The LowCrit temperature value is not checked and its threshold is not displayed on the NPE-G2.

LowWarn

The LowWarn temperature threshold and LowWarn voltage threshold are not checked and the threshold information is not displayed on the NPE-G2.

HighWarn

This is the HighWarn temperature threshold. If the temperature reaches the HighWarn threshold, a warning message is issued for an out-of-tolerance temperature value. The system continues to operate, but operator action is recommended to bring the system back to a normal state.

Note The HighWarn voltage threshold is not checked and its threshold is not displayed on the NPE-G2.

HighCrit

This is the HighCrit temperature or voltage threshold. If the temperature or voltage reaches the HighCrit level, a critical message is issued. The system continues to operate. However, the system is approaching shutdown.

Note Beware that if the temperature reaches or exceeds the HighShut value, a Shutdown message is issued and the router shuts down.

HighShut

This is the HighShut temperature or voltage threshold. If the temperature or voltage level reaches or exceeds the HighShut value, a Shutdown message is issued and the router shuts down.

NPE Inlet   44C/111F  59C/138F

These are the HighWarn and HighCrit temperature thresholds, respectively, for the NPE Inlet.

If the NPE Inlet temperature value reaches the HighWarn (44C/111F) and HighCrit (59C/138F) levels, warning and critical messages, respectively, are issued.

If the value reaches 44C/111F or greater, you receive a warning message indicating HighWarn. The system continues to operate, but operator action is recommended to bring the system back to a normal state.

If the value reaches 59C/138F or greater, you receive a critical (HighCrit) message instead, that indicates the system continues to operate, but the system is approaching shutdown.

Note Beware if the temperature reaches or exceeds 80C/176F, which is the HighShut value, a Shutdown message is issued, and the NPE Inlet area shuts down.

NPE Outlet   49C/120F  64C/147F

These are the HighWarn and HighCrit temperature thresholds, respectively, for the NPE Outlet.

If the NPE Outlet temperature value reaches the HighWarn (49C/120F) and HighCrit (64C/147F) levels, warning and critical messages, respectively, are issued.

If the value reaches 49C/120F or greater, you receive a warning message indicating HighWarn. The system continues to operate, but operator action is recommended to bring the system back to a normal state.

If the value reaches 64C/147F or greater, you receive a critical (HighCrit) message instead, that indicates the system continues to operate, but the system is approaching shutdown.

Note Beware if the temperature reaches or exceeds 84C/183F, which is the HighShut value, a Shutdown message is issued, and the NPE Outlet area shuts down.

CPU Die   75C/167F  85C/185F

These are the HighWarn and HighCrit temperature thresholds, respectively, for the CPU Die.

If the CPU Die temperature value reaches the HighWarn (75C/167F) and HighCrit (85C/185F) levels, warning and critical messages, respectively, are issued.

If the value reaches 75C/167F or greater, you receive a warning message indicating HighWarn. The system continues to operate, but operator action is recommended to bring the system back to a normal state.

If the value reaches 85C/185F or greater, you receive a critical (HighCrit) message instead, that indicates the system continues to operate, but the system is approaching shutdown.

Note Beware if the temperature reaches or exceeds 100C/212F, which is the HighShut value, a Shutdown message is issued and the CPU Die area shuts down.

System shutdown for NPE Inlet is 80C/176F

This is the HighShut temperature threshold for the NPE Inlet.

If the temperature reaches or exceeds 80C/176F, a Shutdown message is issued and the NPE Inlet area is shut down.

System shutdown for NPE Outlet is 84C/183F

This is the HighShut temperature threshold for the NPE Outlet.

If the temperature reaches or exceeds 84C/183F, a Shutdown message is issued and the NPE Outlet area is shut down.

System shutdown for CPU Die is 100C/212F

This is the HighShut temperature threshold for the CPU Die.

If the temperature reaches or exceeds 100C/212F, a Shutdown message is issued and the CPU Die area is shut down.

Table 11 describes the significant fields shown in the display.

Table 11 show environment all Field Descriptions for the Cisco 7500 Series Routers 

Field
Description

Arbiter type 1

Numbers indicating the arbiter type and backplane type.

Power supply

Number and type of power supply installed in the chassis.

Active fault conditions:

Lists any fault conditions that exist (such as power supply failure, fan failure, and temperature too high).

Fan transfer point:

Software-controlled fan speed. If the router is operating below its automatic restart temperature, the transfer point is reduced by 10 percent of the full range each minute. If the router is at or above its automatic restart temperature, the transfer point is increased in the same way.

Active trip points:

Compares temperature sensor against the values displayed at the bottom of the show environment table command output.

15 of 15 soft shutdowns remaining

When the temperature increases above the "board shutdown" level, a soft shutdown occurs (that is, the cards are shut down, and the power supplies, fans, and CI continue to operate). When the system cools to the restart level, the system restarts. The system counts the number of times this occurs and keeps the up/down cycle from continuing forever. When the counter reaches zero, the system performs a hard shutdown, which requires a power cycle to recover. The soft shutdown counter is reset to its maximum value after the system has been up for 6 hours.

Dbus slots:

Indicates which chassis slots are occupied.

card, inlet, hotpoint, exhaust

Temperature measurements at the inlet, hotpoint, and exhaust areas of the card. The (6) and (7) indicate the slot numbers. Dual Route Switch Processor (RSP) chassis can show two RSPs.

Shutdown temperature source

Indicates which of the three temperature sources is selected for comparison against the "shutdown" levels listed with the show environment table command.

Voltages (+12V, +5V, -12V, +24V, +2.5)

Voltages measured on the backplane.

Field
Description

Sample Point

Area for which measurements are taken.

LowShut

Lowest level for an out-of-tolerance condition at which the system shuts itself down. For out-of-tolerance conditions with SPA environment variables, only the SPA is shut down.

LowCrit/LowCritical

Level at which a critical message is issued for an out-of-tolerance voltage condition. The system continues to operate; however, the system is approaching shutdown.

LowWarn/LowWarning

Level at which a warning message is issued for an out-of-tolerance voltage condition. The system continues to operate, but operator action is recommended to bring the system back to a normal state.

HighWarn/HighWarning

Level at which a warning message is issued for an out-of-tolerance voltage condition. The system continues to operate, but operator action is recommended to bring the system back to a normal state.

HighCrit/HighCritical

Level at which a critical message is issued for an out-of-tolerance voltage condition. The system continues to operate; however, the system is approaching shutdown.

HighShut/HighShutdown

Highest level for an out-of-tolerance condition at which the system shuts itself down. For out-of-tolerance conditions with SPA environment variables, only the SPA is shut down.
