What does it mean when an interface shows administratively down?

Thanks.

The port is closed - to open is issues the "no shut" command in the interface config. To place it in admin down again issues the "shut" command in the interface.

Thanks Andrew that was very helpful.

Would you happen to know the correct usage to issue a no shut command for ethernet0 on a PIX 515e running 6.3. I am in conf mode.

Thanks again.

The command that you are looking for is:

interface hardware_id hardware_speed [shutdown]

For instance, this command will enable port ethernet0:

interface ethernet0 auto

This command will disable it:

interface ethernet0 auto shutdown

Here is the command reference for Pix 6.3 for the 'interface' command:
