AIX

I don't understand why you would want to change en2 to en0 - what is the point of doing so?

AIX scans at boot time the buses and attached hardware and numbers the devices found this way. The first found network interface will become en0, the next one en1, etc.. But as these numbers are just that - numbers to set apart the various interfaces - there is simply no point in changing them. The interfaces could as well be named "Jones" and "Smith" or "yellow" and "green". The numbers do not constitute any "priority" or other functional difference between the interfaces.

admin_xor told you already how to change a single interface from en2 to en0. I would just like to add that you have to remove the original en0 first before renaming en2. After that you can run cfgmgr to rescan the hardware inventory and add the original en0 - now probably as en2.

I hope this helps.

Hi,
The interface en2 is connected to network link#3 as per the output of netstat -in command..
That network link#3 should be changed to link#0..
Interface en2 may remain same..
Attached snapshot of AIX netstat -in output..
Please do help soon to sort out the issue..

edit by bakunin: doesn't this belong to the other thread you opened? There you asked how to change a link number too, yes? I am going to merge the two threads.

Hi,

The en2 is connected through link#3..
That link#3 should be changed as link#0..
Please help me to sort out this issue..
Project in mid way...

checked 5 AIX systems with different OS releases (5.3 to 7.1):

no link#0 at all,

lo0 is ALWAYS link#1, first en Interface becomes link#2, and that's en0 most likely


why would you need to change the link number? what do you want to achieve?

Code:

netstat -in | sed 's/link#3/link#0/'

that works great..


Edit:

I think I know what you want, you think the two operating systems can communicate with each other, if the network adapters have the same link number? well that's not the case, have to go now, if no one else does I'll explain this to you later
but first tell me if I'm wrong or not

hmm, i haven't even thought about that - my presumption was at least minimal knowledge of IP networking. Still, you might be right.

I thought of some routing issue, where the default route, bound to en0, is somehow blocked (firewall, lost link, whatever) and he thinks he can bind the default route to another interface (which wouldn't work either).

Anyway, instead of speculating about threadowners motives we might just wait fro him to explain himself as well.

Priya,

It's the best time you explain exactly what you want to achieve and about your project if you really want us to help you.

I have never seen anyone bothered about the "Link#" thing and to be honest I, myself looked at "netstat -in" output uncountable times throughout my career and college/school days almost since I got in touch with Un*x systems without being bothered so much about this "Link#" thing that I didn't realize till yesterday it ever existed

So please let us know what exactly you are upto.

BTW, nothing related to the topic, do you, by any chance, work for IBM? 9 series IP reminds me of IBM internal network

Hi funsken,
You are right about what I exactly want to do..
I need to change the link# of two OS, at link#0 to make a communication..
Please Help!!!!
