With the Security Plus license, you can configure 20 VLAN interfaces, including a VLAN interface for
failover and a 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. You can configure trunk ports to accomodate
multiple VLANs per port.
The ASA 5505 adaptive security appliance supports Active/Standby failover, but not Stateful failover.
