AIX - Determining link speed

I am trying to find a command to return the "link" speed of the networks installed on AIX.

ifconfig - gives me where the link is up and the duplex setting. I need to determine for example if the ethernet connection is 10, 100, 1000 Mbs or what the current speed is based on the network media utilized.

Any help that you can provide would be greatly appreciated.

Thank you!

Two options: 1. entstat -d en? 2. netstat -v
the first option shows extended statistics which include media speed and other stuff. The second looks about the same.

Thank you ddziuk!

Maybe I am not understanding what is returned from my netstat / entstat output.

Here is what I get from netstat -v (it is the same identical output for entstat.

Would you please point out the link speed of this system.

Thank you so much!

lsattr -El <device> -a media_speed

This reads the configuration parameters for this device from the ODM.
