load balancing with 2 lan cards and 2524 switch

[Tapani Tarvainen_1]

Is there a simple way to use two LAN cards connected to same HP2524 switch (no VLANs,?just one subnet) with automatic load balancing?

The switch manual says it supports trunking with HP-UX servers, but no hints about what it involves on the HP-UX side.

This is a small private LAN with only about a dozen machines, so I can do it manually (two IPs, static routes in every host), but if there's an automatic way of achieving it, like when trunking is set up between two switches, it would be better.

In case it matters the host is an L1000 running HP-UX 11.00 (soon 11.11).

Hi, if you are running 11.x then Automatic Port Aggregation (APA) will do this for you. Unfortunately, you have to purchase it. If you do a search on "Port Aggregation", you can find everything you need.
