Continuing our series of posts about the
hardware and software features of ASA firewalls, this article focuses on
the Cisco ASA 5520 model. This model is suitable as Internet
Edge device for medium size enterprises but can be used also for internal LAN
segmentation. From this model and up there are no Base License or Security Plus
License options, like the 5505 and 5510 models. Also, the four integrated
Network Interfaces by default support gigabit 10/100/1000 speed. There is an
additional Management Interface which supports Fast Ethernet speed (10/100
Mbps). This Interface can be used as normal firewall interface by issuing the “no
management-only” interface configuration command. So there are essentially
five network interfaces integrated on the appliance.
