When I upgrade the ios on switches, I just create int vlan1 assign it an ip and subnet, then tftp to my pc that is plugged into the switchport using the download-sw command.

I am not sure how to do this on the asa.  Do I just plug my pc into port 0 which the documentation says is mapped to vlan 1 with and ip of

I tried this by making my pc's ip but am unable to ping the asa.  Do I have to change the security level or anything?

I am new to the ASA's

Hi Mike,

Port 0 is the only port that is assigned to a different Vlan, you should plug your computer to any other port other than 0 and you will be able to reach the ASA using the IP address Make sure thou that your laptop remains using and IP on the same subnet as the ASA firewall.

Try it out and let me know.
