Cisco ASA 5585-X Port Numbering

KB ID 0001004 


Back at the beginning of the year I had to do a firewall design that included an ASA5585-X, I did some searching to find out how the ports were numbered but came up blank. So I took an (incorrect) educated guess.

I unboxed and fired one up today, and ran though the port numbering and orientation, and discovered the correct numbering.


Note: This ASA5585-X also has a CX module fitted. The bottom ‘blade’ is the ASA firewall, and the one at the TOP is the CX module. With the CX module fitted, we have an extra eight gigabit Ethernet ports, and two more ten gigabit Ethernet ports.
