can ifconfig work this way ?

cgzou — Wed, 26 Mar 2003 20:54:44 GMT

hello all,

ifconfig lan1:0 0
ifconfig lan1:1 x.x.x.x
skip 2 and 3
ifconfig lan1:4 y.y.y.y

The reason I issue the first command is to avoid that complain that the "primary interface must first configured" problem.

Any input is appreciated!
thanks,

I don't think its going to work.

The primary interface needs to be configured.

You can not have two lan's on the same network and subnet. If you try and issue such a command on an HP-UX box networking will stop functioning.

Instantly.

x.x.x.x and y.y.y.y will be on the same subnet. Is it still a problem?

I have tried to issue the following commands on one of the lan card(not physically connected, I can't verify that through a ping), it didn't give any warning:

ifconfig lan1:0 0
ifconfig lan1:2 x.x.x.x

So can someone verify that is it going to work? which means you can still reach x.x.x.x through lan1 even though the primary not configured.

By the way, what is the maximun # of index we can use for lan1:index? ( this is not critical issue for me though)

Thank you!

Hi,

I am not able to think of any reasons why it won't work.

You should be ok unless you have ServiceGuard on them. You may get into issues if you try to run cmquerycl etc.,.

Service guard wasn't mentioned here. The configuration won't work on a single machine. I accidently tried something like that and report actual results earlier.

Though not a service guard expert, nothing I posted has anything to do with service guard setup.
