Hi,
I would like to know how to find out ACTUAL speed of NIC Card.
I have used the command ethtool eth0, it is showing supported modes,
but what is acutal speed ? how to find out?

# ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s <-------------- !
Thanks RudiC,I am confused becuase mii-tool is showing diffrent speed.
output of eth-tool
ethtool eth1
Settings for eth1:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 1000Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Link detected: yes
output of mii-tool (below command is showing different NIC speed)
mii-tool eth1
eth1: negotiated 100baseTx-FD flow-control, link ok
I don't think gigabit uses mii anymore. That is to say, mii has no way of reporting speeds above 100baseT, a new standard was made.
Many Many Thanks Corona688.
