APA "split trunking"

[Samuel Scott]

Can someone point me to documentation on how to set up the configuration files for a split trunking configuration in APA? The only document I've seen focuses on setting up the switches and only gives a few lanadmin commands to set up HP-UX. (http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02037960/c02037960.pdf )

As far as I understand, "split trunking" is a way to make two (or perhaps more) switches essentially work as one big switch, as regards to the IEEE 802.3ad link aggregation.

As a result, the APA configuration on the server side should not be fundamentally any different from the case of a regular link aggregate configuration with one switch only.

You're correct Matti.

My confusion is this. I created an aggregate of 4 NICs called lan900. Everthing seems to be working, but two aggregates were created, lan900 and lan901. I never created lan901. The NICs are each going to the correct switch and seems to be working ok.
