Hi Guys,
I need help with ndd.
I was going through network FAQ in this site but i am left with more questions then answers regarding ndd.
#ndd -set /dev/hme instance 0
#ndd -set /dev/hme adv_100fdx_cap 1
#ndd -set /dev/hme adv_100hdx_cap 0
#ndd -set /dev/hme adv_10fdx_cap 0
#ndd -set /dev/hme adv_10hdx_cap 0
#ndd -set /dev/hme adv_autoneg_cap 0

Wanted to know what 0 and 1 mean and what adv_100fdx_cap, adv_100hdx_cap,adv_10fdx_cap,adv_10hdx_cap,adv_autoneg_cap mean.

Basically i want to change my server interface form half to full duplex and also speed.

Please help!
 
0=off
1=on
fdx=full duplex
hdx=half duplex
adv_autoneg_cap=autonegotiate
10=10Mbps
100=100Mbps
1000=1000Mbps
 
And btw, the nic you show is 100 full.
 
I am sure you will get a better explanation.

0 and 1 have different meanings, it depends on the ndd setting:

The "instance" of zero first sets it to which hme, so you are twiddling hme0 in your example.

adv_autoneg_cap disables or enables auto negotiation, you have it disabled.

And you have hard coded to 100 Full duplex.

Obviously, the ones with 100 are 100Mb and 10 are 10mb,
fdx is full and hdx is half.

So if you want to force, only 1 speed/duplex setting should be set. And make sure your switch is set to the same setting, not auto.
