Chapter 4 Configuring Switch Ports and VLAN Interfaces for the Cisco ASA 5505 Adaptive Security Appliance
Interface Overview
Figure 4-1 ASA 5505 Adaptive Security Appliance with Base License
With the Security Plus license, you can configure three VLAN interfaces for normal traffic, one VLAN
interface for failover, and one VLAN interface as a backup link to your ISP. This backup interface does
not pass through traffic unless the route through the primary interface fails.
Note The ASA 5505 adaptive security appliance supports Active/Standby failover, but not Stateful failover.
See Figure 4-2 for an example network.
