[OpenIndiana-discuss] link property e1000 / igb

[Randy S]

Hi all,

version OI5a7

I'm trying to force a nic to work at 1000 mb. 
To
 test the commands first, I usually  test it on a testsystem. I 
found some docs from oracle stating that if you want to force a nic to 
perform at a certain speed, you should disable advertising the speeds 
that you don't want with the command: dladm set-linkprop -p adv adv_100fdx_cap=0 e1000g0 
and
dladm set-linkprop -p adv_100hdx_cap=0 e1000g0

afer executing the commands I get :
dladm: warning: cannot set link property 'adv_100fdx_cap' on 'e1000g0': read-only property
and
dladm: warning: cannot set link property 'adv_100hdx_cap' on 'e1000g0': read-only property


dladm show-linkprop e1000g0 gives:

and thus shows thes props as read-only. 

So how do you force a nic to perform at 1000Mb in OI?

High regards,
