First time with cisco CLI

Noob alert, sorry if this is really easy but I'm stuck and google seems not helpful this time

​

So, I was trying to run the TDR test on a Cisco IE2000 switch, it seems to work via webpage but I want to give it a try via CLI.

I connected via USB (because yes, I wasn't able to ssh in it), I learned how to show interfaces, now I want to do the cable test.

According to all the websites, videos and documentation, it seems that I need to run the test cable tdr command followed by show cable tdr, but that's the error I get

​

any idea?
