I have just been asked to install a ASA 5510 into our network. I have never used an ASA device so i am looking for the best way to connect it into the network. It will be connected to a 3560 switch. which is part of a vtp domain with 15 vlans. Can i add the ASA over a trunk? I have read that i need security plus license to do this. If this is the case do i need to configure a route on the switch? Any ideas will help.
