ethool eth0

will provide current mode.

See "man ethoool" for more [how to change settings and so on]

As usually in Linux, you have few ways to set NIC parameters:

1) mii-tool [doesn't work for some NIC, for example for Broadcom]

2) in /etc/modules.conf you can use module parameters for setting speed/duplex mode - unfortunately, syntax of such parameters isn't standart

Show the link status using "mii-diag" tool.
# mii-diag -a

The driver output found from the "dmesg" command will usually display the settings as well.

[K.C. Chan]

mii-tool will show something like this:
eth0: negotiated 100baseTx-FD, link ok

[Peeyush]

try

dmesg | grep eth0

if u want to change its setting u can edit /etc/modules.conf

options eth0 line_speed=100 full_duplex=1

service network restart

It displays speed an duplex on newer distributions.
