Feature History for ASA 5505 Interfaces
Table 7-1 lists the release history for this feature.
Table 7-1 Feature History for Interfaces
Feature Name Releases Feature Information
Increased VLANs 7.2(2) The maximum number of VLANs for the Security Plus
license on the ASA 5505 was increased from 5 (3 fully
functional; 1 failover; one restricted to a backup interface)
to 20 fully functional interfaces. In addition, the number of
trunk ports was increased from 1 to 8. Now there are 20
fully functional interfaces, you do not need to use the
backup interface command to cripple a backup ISP
interface; you can use a fully-functional interface for it. The
backup interface command is still useful for an Easy VPN
configuration.
Native VLAN support for the ASA 5505 7.2(4)/8.0(4) You can now include the native VLAN in an ASA 5505
trunk port.
We introduced the following command: switchport trunk
native vlan.
