It presents to you the contents of a particular directory both files and directories. ls The ls command is probably one of the most widely used commands in the Unix world. Consider the system performanceĪnd loop detection speed when you set the loop detection interval. This is one of the handiest Linux terminal commands that aims to make new user’s life peaceful by ensuring they don’t get lost in that seemingly cryptic terminal window. More sensitive detection but consumes more resources. Sends loop detection frames at the specified interval. The loop detection interval is 30 seconds.ĭetection interval in the range of 1 to 300 seconds. In Windows, just typing cmd into the taskbar search box and hitting Enter launches Command Prompt, but for some of these commands you need administrator privileges. Loopback-detection interval-time interval Use undo loopback-detection interval-time to restore the default. Use loopback-detection interval-time to set the loop detection interval. Loopback-detection enable loopback-detection interval-time # Globally enable loop detection for VLAN Loop protection action is triggered on that port, regardless of whether loop When a port receives a detection frame in any VLAN, the You can enable loop detection globally or The ID for vlan-id2 must be equal to or greater than the ID for vlan-id1. For example, to require a shutdown at 7 AM in the morning, the command is: sudo shutdown 07:00. The value range for VLAN IDs is 1 to 4094. The command follows the syntax: sudo shutdown hh:mm. Each item specifies a VLAN ID orĪ range of VLAN IDs in the form of vlan-id1 to vlan-id2. Loopback-detection action Ī space-separated list of up to 10 VLAN items. Use undo loopback-detection action to restore the default. Use loopback-detection action to set the loop protection action on a per-port basis. Set the time interval by using the shutdown-interval command (see Fundamentals Command The device automatically sets the port to the forwarding state after a time ¡ Shuts down the port to disable it from receiving or sending frames.

No-learning -When a loop is detected on a port, the device logs theĮvent and disables the port from learning MAC addresses.None -When a loop is detected on a port, the device logs theĮvent without taking any action on the port.¡ Disables the port from learning MAC addresses.

Use display loopback-detection to display the loop detection configuration and status. For example, if on Raspberry Pi shutdown you also want to turn off the cooling fan connected to the 5V and GND pins – programmatically only this can’t be achieved.This feature is supported only on the LayerĢ Ethernet ports on Ethernet switching modules. Turn OFF/ON Power Pin: The pins 5V, 3V3 and GND are directly connected to the power supply and can’t be controlled by software. Reboot Raspberry PiĮxecute any of the following commands to restart RPi safely: $ sudo reboot

If only the red LED is on, everything is good as it just indicates that the Raspberry Pi is connected to a stable power supply. When the shutdown process has finished, the green LED blinks several times – after this it is safe to pull the power cable out. Use any of the commands below to shutdown RPi safely: You can now control your Mac and execute Terminal commands remotely, a real plus. Replace username with the username you'd use to log into OS X and remote-address with the IP address given to you in the Sharing pane. After some time it sends SIGKILL to all remaining processes, unmounts all the file systems and finally tells the kernel to issue the ACPI power command. To log into your Mac on another Mac, execute the command: ssh -l username remote-address. Safe Shutdown: When RPi (or any other UNIX-like system) is shutting down or rebooting normally, using the commands from terminal or their GUI equivalents, firstly it tries to exit all processes gracefully by sending SIGTERM signal, notifying them to save their data and exit.

In this note i will show how to shutdown or reboot Raspberry Pi safely from the command line.Ĭool Tip: Check the CPU/GPU temperature of Raspberry Pi! Read more → To shutdown or reboot Raspberry Pi safely through the GUI, simply search the menu for the corresponding buttons. If you don’t want to corrupt the file system on SD card, you should always shutdown and reboot Raspberry Pi correctly (not just by pulling the power cable out).
