Multiple NICs with same IP address

Xavier Gutierrez — Mon, 14 May 2001 06:57:45 GMT

What is the way to configure multiple LANICs to have the same IP address? (On the same 9k server and for load balancing purposes)

Thanx in advance

If you have HP-UX 11.x installed, then you need to look at using Auto Port Aggregation (APA).
This is a supported method of load balancing, as well as increasing throughput.
For 10.x there is no supported way of doing this, and if you do put NIC's on the same IP Address, you will have problems.

In fact, what i'm looking for is the exact command that will do it. I also would like to know if it is possible to do it through SAM.

I would recommend you read:
HP Auto Port Aggregation (APA) User's Guide

available at:

This has the how-to-do-it stuff.
