How to determine the connection speed

I’ve been asked this several times so I hope this little article will help many people. The question is: how do I determine the connection speed negotiated with the switch? Many ask this because they want to be sure that they are getting what they pay for. Please note that this is will NOT determine your server max speed but rather it will tell you the connection speed negotiated with the switch.

Simply run as root:

# mii-tool

This will output something like:

eth0: negotiated 100baseTx-FD, link ok
