Configuring Switch Ports and VLAN Interfaces for the Cisco ASA 5505 Adaptive Security Appliance
Figure 4-1
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.
The ASA 5505 adaptive security appliance supports Active/Standby failover, but not Stateful failover.
