Active/Passive NICs

How do you configure dual NICs. One is active, and second one is passive?


Can you have have two NICs and have them active? If so how?

Re: Active/Passive NICs

For Active/Active configuration, you'll need Auto-Port Aggregation (APA): it used to be a separate product, but became a standard part of HP-UX 11.31 in newer releases.


For Active/Passive configuration, you can use either APA or Serviceguard, although APA offers more options.

(Using Serviceguard just for this purpose only makes sense if you already have a Serviceguard license you aren't using for any other purpose.)


The idea of APA is that you join two or more physical NICs (e.g. lan0 and lan1) into a single aggregate interface (in HP-UX 11.31, typically lan900 or above). This aggregate interface can then be configured just like a regular NIC.


In HP-UX 11.31, the easiest way to configure APA is to use the System Management Homepage (SMH). You can also use command-line tools to configure APA if you wish.


You can find the APA documentation here:


Click on "HP-UX Auto Port Aggregation (APA) Software", then go to the User Guide section and find the guide that is appropriate for your HP-UX version.
