Cisco ASA 5550 Features

Now let us see the next ASA model in the series which is the Cisco ASA 5550. With over one gigabit firewall performance (1.2 Gbps) this appliance can be easily used on ISP public services segments or on medium data rate campuses and data centers. From this model and up, there is no support for Security Services Module (SSM), so basically you can not include an IDS/IPS or Content Inspection functionality integrated inside the box. However, with this model you get the advantage of having eight gigabit integrated copper ports (8-10/100/100) PLUS four optical gigabit ports (4 SFPs), which means you will not run out of network port capacity easily.
