Example for hme1 ;

ndd -set /dev/hme instance 1 -> further ndd commands will apply to /dev/hme1

ndd /dev/hme adv_autoneg_cap -> Are we autonegotiating? 1=true, 0=false

ndd /dev/hme link_speed -> Link speed? 1=100Mb/s, 0=10Mb/s

ndd /dev/hme link_mode -> Duplex mode? 1=FD, 0=HD

Change as appropriate :-)

You can see what speed the card has come up in /var/adm/messages

Jul 4 10:45:21 florida eri: [ID 786680 kern.notice] SUNW,eri0 : 100 Mbps full duplex link up

Also check out this cool cool script. The speed and duplex setting are stored in the Kernel and can be pulled out using this script, which formats them in a nice way for you.

Hope this helps!

And if you just have a plain Solaris machine then `kstat` is also able to give you the right information.
