Re: NIC duplex changes

Hi Larry,

2006/10/17, Larry Scheetz <LScheetz@xxxxxxxxxxx>:


I am running a server with AIX 4.3.3. When I run a entstat –d en0 it is
showing that I am running auto negotiate and 100HD. I need to change this
on my end and make it 100FD. Below is the steps that I was thiking would
work. Could anyone tell me if this would work to make minimal downtime.


1: Ifconfig en0 down

2: Ifconfig en0 detach

3: Chdev –l ent0 –a media_speed=100_Full_Duplex

4: Chdev –l en0 –a state=up



Please let me know if this would make the changes on the fly.

Yes, the changes could be make on the fly but only from console(!)
(or maybe from another session thru ent1...)
In my experience:
chdev -l en0 -a state=detach
chdev -l ent0 -a media_speed=100_Full_Duplex
chdev -l en0 -a state=up
If the default gateway via en0 it need recreate. See the netstat -r output
before and after the en0 state change.
I hope this help.
Cheers, Zoltan
