Hi , I am fairly new to the Firepower services, I am currently ordering equipment for a client, namely 2x 5516-FPWR-Bun Firewalls, I just want to confirm 2 things, Do I need a FirePower IPS Licence (L-ASA5515-TA) per device? and secondly do I only need to order 1 Cisco Firesight Management Centre,(VMware) as it support 2 devices ?
