Cisco ASA 5540 Model
The Cisco ASA 5540 appliances provide security services to medium to large enterprises. The Cisco ASA 5540 model supports a higher number of security contexts (50) to provide more flexibility and compartmentalized control of security policies. It also provides support for up to 10 appliances in a VPN cluster, supporting a maximum of 50,000 IPSec VPN peers per cluster (25,000 for WebVPN).
Cisco ASA 5540 is also a 1RU device. The external front and back layouts of Cisco ASA 5540 appliance are identical to those of the Cisco ASA 5510 and 5520 appliances. Figure 3-5 illustrates the front view of Cisco ASA 5540.
Figure 3-6 illustrates the back view of Cisco ASA 5540.
Table 3-3 lists the capabilities of the Cisco ASA 5540 appliance and its performance and connection limit numbers.
