I don’t know exact terms. I don’t know how to call it. I don’t know what terms to search for.

I can check the connection speed from my computer to the device it is connected to – AP, or switch. On my computer it says 100 Mbps or 1000 Mbps – it depends how my “computer” did negotiate speed.

Hot to check this kind of speed from RouterOS device to another network device? For example on my computer it says 1000 Mbps (from my computer to RouterOS device), what speed has negotiated my Mikrotik device with the internal router? It this information the same if the Mikrotik is connected to another device wired or wirelessly?

Thank you for help.

For wired connections, you can run command
(replace ether1 with name of port you want to check).
Or you can check multiple interfaces by running /interface ethernet monitor numbers=0,1,2,3,4 once.

For wireless clients you can run command

This command just gives you infromation what is being advertised, not the end result, what has been negotiated.

This command just gives you infromation what is being advertised, not the end result, what has been negotiated.

It's because the link is down in your case. When the link is up, the result looks as follows:

formatted code

[me@MyTik] > /interface ethernet monitor ether1 once
                      name: ether1
                    status: link-ok
          auto-negotiation: done
                      rate: 100Mbps
               full-duplex: yes
           tx-flow-control: no
           rx-flow-control: no
               advertising: 10M-half,10M-full,100M-half,100M-full,1000M-half,1000M-full
  link-partner-advertising: 10M-half,10M-full,100M-half,100M-full

Sorry. I looked at the unplugged interface. :(

That command shows the needed information for ether2.
Thank you.

This part is for Google and other users might need this kind of information.

That information can also be found in Winbox -> Interfaces -> double click on the interface -> in the Status tab -> the information what is being advertising and negotiated rate
