In this post I would like to show you some useful commands available on the Arista switches that you can use in your daily work.

The first command that is very useful is the watch command, which repeats the given command at a specified interval and can additionally display the differences between individual performances.

For example, if we want to monitor CRC errors on a given interface, instead of repeating the show int x / x several times, we can use the watch command, which will run the above mentioned command automatically every 2s and display information as shown below.
