No - it's not possible, with a basic license, you need a Security Plus license.

Sub Interface on Cisco ASA 5505

I have been working on a configuration in which I wanted to do subinterfaces as well.  I found that you can not create them even with having a security plus license.

Sub Interface on Cisco ASA 5505

Hi,

To my understanding you only configure Vlan interfaces on the ASA5505 just like a L3 Switch.

For example

interface Vlan10

nameif LAN

security-level 100

ip add 10.10.10.1 255.255.255.0

interface Ethernet0/1

switcport access vlan 10

Then you either make physical ports on the ASA5505 as Access Mode ports on that Vlan ID or configure a physical interface as a Trunk

Configuring the Trunk will require the Security Plus License.
