Cisco ASA 5525-X Internal Interfaces

[g-campbell]

Hello,

This is my first time working with the X genertaion of firewalls.  I note from an output of show interface ip brief I get an additional 4 interfaces along with the gigabitethernet interfaces, namely:

Internal-Control0/0        127.0.1.1       YES unset  up                    up

Internal-Data0/0           unassigned      YES unset  up                    up

Internal-Data0/1           unassigned      YES unset  down              down

Internal-Data0/2           unassigned      YES unset  up                    up

I am struggling to find any documentation as to what these interfaces are and what exactly it is they do and kindly ask if anyone has knowledge, a link or a white paper or architectural document to explain this for me.

Regards
