SSH command for adding latency

I want to add latency to emulated a networking delay, but I am unaware of where to find a list of the SSH commands for gl.inet. Does anyone know the command for adding a delay as well as clearing it when I am done using it?

What instructions do you want to use to simulate network latency,tc?

Hello, I am not very well versed in Linux/terminal commands, but I see tc has controls for simulating network latency through netem. Could you please tell me how to get it installed and add latency, then clear the latency when I am done?
