The Cisco ASA series of firewall appliances has been in the market for a long time when they replaced the older PIX hardware firewalls. However many professionals and companies still have older ASA series firewall appliances in their network and are looking to find some specs and throughput performance characteristics for them.
The ASA is the smallest model in the series and is suitable for small businesses or small branch offices and teleworkers. As it is a smaller size compared with the other models, it is not rack-mountable. It is the only model also that comes with an 8-port switch with 2 power over Ethernet ports.
The Cisco ASA features depend on which software license is installed. There are two license options available:. Continuing our series about the hardware and software features of ASA firewalls, this section focuses on the Cisco ASA model which is a very popular appliance for small to medium enterprises.
Similarly with the , the ASA comes also with two types of software licenses: Base License and Security Plus License, with the later offering advanced hardware and performance features. 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 and models. So there are essentially five network interfaces integrated on the appliance. As you can see from the Maximum throughput spec above Mbps , it means that although the appliance supports gigabit interfaces, the limiting factor is the actual firewall throughput.
If one of the interfaces received 1Gbps traffic from an external source, traffic will be queued in buffers and if the rate continuous like this then it will be tail-dropped. This device is geared towards large enterprises which need firewall throughput of Mbps. This enhancement makes the ideal for replacing the older VPN Concentrator device. With over one gigabit firewall performance 1.
The is designed for the largest and most traffic demanding network topologies. It is ideal for high-speed data centers and large campus networks. It supports the largest firewall throughput in the hardware firewall market, with 5 Gbps and 10 Gbps capacity. It is also the only model supporting 10Gbps interfaces.
