How to find out my NIC speed (10/100/1000)


Hi,

Is there a utility that comes with my Linux RedHat that I can find out what is my NIC current speed (10/100/1000Mbps)?

TIA.

ethtool perhaps if the NIC driver is supported by it.

Well, if you cant figure it out with software, You know your not running 1000 unless your connected to a gigabit network, and most network cards will have a little light indicating whether it is running at 10 or 100Mbps. you could check the back of the card (hardware level).

Nope. The ethtool returns device not supported.

What other ways that I can determine the speed without checking the LED at the back of the card?

Well you can always try something like this.

Code:
>$ dmesg |grep eth0
eth0: VIA Networking Velocity Family Gigabit Ethernet Adapter
eth0: Ethernet Address: 00:50:8D:D1:28:6B
eth0: Link autonegation speed 100M bps full duplex
Or course changing the eth0 to eth1 or such if different even eth* for any ethernet card detected.
