Cisco IOS Release 15.2(1)T Feature

The following software feature is documented in this guide:

Temperature and Voltage Monitoring (TVM)

Temperature and Voltage Monitoring (TVM)

Temperature and Voltage Monitoring (TVM) is a software feature that provides support for monitoring the router operating temperature and the router power supply voltage. This section describes the TVM feature and includes the following topics:

TVM Overview

How to Configure TVM

MIB Support for TVM

TVM Overview

Operating Temperature Monitoring

During normal operation, the router hardware uses sensors to measure the internal temperature of critical router components, including the central processor and any installed interface cards. The router uses the individual component temperatures to calculate its operating temperature.

Using TVM, you can configure the router with maximum and minimum operating temperatures, called thresholds, to define an operating temperature range for the router. You can then configure the router to send a notification when it detects that the operating temperature is out of the defined range. Notifications can be in the form of system log messages or SNMP notifications.

The section Configure Operating Temperature Monitoring, provides instructions for configuring this functionality.

Power Supply Voltage Monitoring

TVM supports power supply monitoring features that are similar to the operating temperature monitoring features. You can configure voltage ranges for the router power supply and then configure notifications to be sent when the power supply voltage is out of the defined range.

The section Configure Power Supply Monitoring, provides instructions for configuring this functionality.

Supported Power Supplies

The power supply voltage threshold range supported by TVM is different for each power supply model used with the router. The router power supply models are listed in Table 1, along with the supported voltage thresholds for each model.

For detailed information about these power supplies, refer to the router hardware installation guide.

Low: 75 to 80 volts


Historical Data Collection

TVM supports historical data collection and storage for temperature and voltage. You can configure the router to save historical data about the router operating temperature and power supply voltage. Related features include:

A show command that displays temperature and voltage data for up to 72 hours in the past.

An enhanced MIB for historical data retrieval so that network management systems can collect report data from the router.

These sections provide instructions for configuring historical data collection:

Configure Operating Temperature Monitoring

Configure Power Supply Monitoring

Monitoring and Storage Intervals and Periods

This section describes how often the router monitors and stores temperature and voltage data.

Monitoring Interval—The router checks the operating temperature and power supply voltage once per minute. The monitoring interval is not configurable.

Storage Interval—The router stores temperature and voltage data as follows:

Every 60 seconds, the router stores the actual, measured temperature, and voltage.

Every 60 minutes, the router stores the average of the 60 measurements taken during the previous hour.

Storage intervals are not configurable.

You must enable the router to store the data that it collects at the monitoring intervals using the monitor environment temperature and the monitor power-supply voltage commands. These sections provide instructions for enabling data collection and storage:

Configure Operating Temperature Monitoring.

Configure Power Supply Monitoring.

Maximum Date Storage Period—The router stores temperature and voltage data for a maximum of 72 hours. After 72 hours, the oldest data is purged when the router adds the most recent data. The storage period is not configurable.

Alarms—At each monitoring interval, the router checks the operating temperature and power supply voltage. If the router detects that either is out of range of the defined thresholds, it generates an event notification (SYSLOG or SNMP). These sections provide instructions for configuring notifications:

Configure Operating Temperature Monitoring.

Configure Power Supply Monitoring.

Show Commands

The TVM feature includes show commands to view the history configuration and stored data for both operating temperature and power supply voltage.

The section Using TVM Show Commands, provides instructions for using this command.

How to Configure TVM

This section describes the TVM configuration commands supported in Cisco IOS Release 15.2(1)T and later.

Configure Operating Temperature Monitoring

Use the monitor environment temperature global configuration command to configure router operating temperature thresholds. These thresholds define an operating temperature range so the router can be configured to send notifications when the temperature is out of the desired range.

You can also use this command to:

Enable historical data collection for router operating temperature.

Disable the specified setting, using the no form of the command.

Reset operating temperature thresholds to the default value, using the no form of the command with the low and high options.

This table describes the command options for the monitor environment temperature command.

Command Syntax
Description

monitor environment temperature {history | low celsius | high celsius | notifies | syslog}

The monitor environment temperature global command configures the thresholds, alarm settings, and historical data settings for the router operating temperature.

history—Enables data collection of the router operating temperature. The default setting is disabled.

high celsius—Maximum temperature in degrees celsius that, when exceeded, triggers the router to send a notification. The range is -150 to 300. The default value is 110.

low celsius—Minimum temperature in degrees celsius that, when not met, triggers the router to send a notification. The range is -200 to 250. The default value is -25.

notifies—Generates an SNMP trap when the router operating temperature is out of range of the configured threshold values. The default setting is disabled.

syslog—Generates a SYSLOG message when the router operating temperature is out of range of the configured threshold values. The default setting is enabled.


Configure Power Supply Monitoring

Use the monitor power-supply voltage global configuration command to configure router power supply voltage thresholds. These thresholds define a voltage range so that the router can be configured to send an notification when the power supply voltage is outside the desired range. You can also use this command to:

Enable historical data collection of power supply voltage.

Disable the specified setting, using the no form of the command.

Reset power supply voltage thresholds to the default value, using the no form of the command with the low and high options.

This table describes the command options for the monitor power-supply voltage command.

Command Syntax
Description

monitor power-supply voltage {disable | history | notifies | syslog | threshold ac-dc {high volts | low volts}| threshold low-dc {high volts | low volts}}

The monitor power-supply voltage global configuration command configures the power supply thresholds, alarm settings, and historical data settings for the router power supplies.

disable—Disables threshold notifications for the power supply.

history—Enables historical data collection for the power supplies. The default setting is disabled.

notifies—Generates an SNMP trap when the power supply voltage is out of range of the configured threshold values. The default setting is disabled.

syslog—Generates an SNMP trap when the power supply voltage is out of range of the configured threshold values. The default setting is enabled.

threshold ac-dc—Configures the maximum and minimum threshold values for the power supply. Use this option for power supply models PWR-RGD-AC-DC and PWR-RGD-AC-DC-C.

threshold low-dc—Configures the maximum and minimum threshold values for the power supply. Use this option for power supply model PWR-RGD-LOW-DC.

high volts—Maximum power supply voltage that, when exceeded, triggers the router to send a notification. The ranges are:

ac-dc high: 275 to 300

low-dc high: 75 to 80

The default values are:

ac-dc high: 275

low-dc high: 80
