Dual-homed APA

Hi,everybody.

These days, I have one problem for APA with a dual-home backbone system.

Ofcourse, I solved this problem but, there is one question for the follow situation at that time.

My HP server has two NICs.

The two NICs of HP server (HPUX 11.2i) with APA/LB_MAC/HOT_STANDY=off was attached each to the dual backbone system (Network Backbone #1, #2).

This HP Server would be worked on APA with LACP automatically. Is it right?

The difference is that my two backbone wasn't configured to LACP for each port to the Server NIC 1 and NIC 2.

My backbone is tunked to the other backbone.

Summary :
1) Backbone1 - Backone2 : trunked
2) Backbone1 port(to NIC1) : NO TRUNK (no LACP)
3) Backbone2 port(to NIC2) : NO TRUNK (no LACP)
4) HP server NIC1 - Backbone1 : connected
5) HP server NIC2 - Backbone2 : connected
6) HP server APA (for NIC1&2) : APA/LB_MAC/HOT_STANDY=off

In this situation, My network backbone #1 and #2 would be forwarded to the two NIC of HP server in turns.

So that, the Server NIC 1 and 2 will be recevied in turn for one session!

Here is my two questions.

1) This HP Server would be worked on APA with LACP automatically. Is it right?

2) Is there any problem that the packets of same session will be forwarded to the different NIC from the network backbone?

Please answer me!
Thanks a lot.
