Force Cisco ASA interface up without physical connection?

Posted on 2010-01-03

How can I make an ASA interface show as up without having it physically connected to anything?  It's easy to do this in IOS, but I haven't been able to find a method for ASA.  I need a method for both physical and logical (vlan subif) interfaces.  I am running 8.0(3)19.

                       A lower security_level interface is outside relative to a higher level interface and equivalent
                       interfaces are outside to each other

    In short Its not possible to keep the port up without a physical connection.

    I have also observed that the Ipsec tunnel would not be up if your inside network port/vlan is not up.

    Hope this helps
