Use the sensors command to monitor the health of your switch hardware, such as power, temperature and fan speeds. You can also run these NCLU commands to show sensor information: net show system sensors, net show system sensors detail, and net show system sensors json. Optionįor more information, read man smond and man smonctl. The following table shows the smonctl command options. The Penguin Arctica 3200c does not have this sensor: sudo smonctl -v -s PSU1 Some switch models lack the sensor for reading voltage information, so this data is not output from the smonctl command.įor example, the Dell S4048 series has this sensor and displays power and voltage information: sudo smonctl -v -s PSU2 Temp4 (Right side of Networking ASIC ): OK Temp1 (Networking ASIC Die Temp Sensor ): OK Use smonctl to display sensor information for the various system units: sudo smonctl smond utilizes these registers to read all sources, which impacts the health of the system unit, determines the unit’s health, and updates the system LEDs. Changes in system unit state are detected via the cpld registers. The smond daemon monitors system units like power supply and fan, updates their corresponding LEDs, and logs the change in the state. You can use apt-get to install the lshw program on the switch, which also retrieves hardware configuration information. You can also use the dmidecode command to retrieve hardware configuration information that is populated in the BIOS. Prints the base MAC address for management interfaces.Ĭlears and initializes the board EEPROM cache This is because the BMC connects to the PSUs via I2C and the main CPU of the switch has no direct access. Note: Some systems that use a BMC to manage sensors (such as the Dell Z9264 and EdgeCore Minipack AS8000) do not provide the PSU EEPROM contents. Prints the target EEPROM (board, psu2, psu1) information. If args is empty, the values will be prompted interactively. If args are supplied in the command line, they will be written without confirmation. Fields that are not specified default to their current values. , and = are illegal characters in field names and values. args can be supplied in the command line in a comma separated list of the form =. Sets the EEPROM content if the EEPROM is writable. Prints the number of MACs allocated for switch interfaces. Prints the base MAC address for switch interfaces. Usage: /usr/cumulus/bin/decode-syseeprom ] Option The command output is different on different switches: decode-syseeprom If the EEPROM is writable, you can set values on the EEPROM. The decode-syseeprom command enables you to retrieve information about the switch’s EEPROM. Retrieve Hardware Information Using decode-syseeprom You monitor system hardware using the following commands and utilities: If you are redirected to the main page of the user guide, then this page may have been renamed please search for it there.
