ifconfig question: virtual interfaces/subinterfaces?

Edwin R. Rivera_1 — Fri, 08 Feb 2002 20:44:20 GMT

hello all,

My company is planning to move to a new subnet over the weekend. I have a few HP-UX boxes that i'm responsible for here.

what i'd like to ask is if there is a way to `ifconfig` some virtual interfaces so that my boxes can be on both LANs at the same time?

i know with linux it's simply:
ifconfig ethx:x xxx.xxx.xxx netmask xxx.xxx.xx.xxx up

however, i have one hp-ux10.20 and two hp-uxv11.0 boxes here and i'm not too familiar with this o/s.

thanks for any help you can offer

regards,

edwin

Hi,

Multiple ip_address for a single card is supported in HP-UX also. You can logically assign multiple ip_address for cards using 'logical instances'.

For eg: lan0:0 - where the last 0 stands for logical instance. lan0:0 is same as lan0. The next logical instance will be lan0:1.

But I don't think this function is supported in HP-UX 10.20. It is supported from version 10.30 onwards. You can try and test it.

For more useful information regarding configuration, check this out:
