HPUX Port Aggregation and Network Loop

[Darren Etheridge_2]

We have 2 HPUX machines both using HP Port aggregation linked to a Procure 5406zl switch.  In the switch the ports for each server are trunked.   But I just ran a network analysis with Capsa software and it shows a network loop with both servers.  Luckily we have STP turned on in the switch, but if APA is running and the ports are trunked, why would a network loop be showing on the APA ports?
