Any suggestions would be helpful

Hi Edwin

Please see the following for the 5505,

http://www.cisco.com/en/US/docs/security/asa/asa82/configuration/guide/intrface.html#wp1072137

You assign each switch port to a VLAN interface or have a trunk interface for multiple VLAN's.

Please rate if this helps

Hi Edwin,

ASA5505 does not support subintercface (as the ports are switch ports). Please check the below  discussion as well.
