Cấu hình từng bước :
1. Command-line interface ;
Khi truy cập vào Pix sẽ vào mode unprivileged , sử dụng enable
command để vào mode privileged
pixfirewall>enable
password :
=> trước khi vào mode enable , pix sẽ yêu cầu nhập password ,
mặc định là không có password nào cả , chỉ cần nhấn enter
pixfirewall#disable
pixfirewall> ß sử dụng disable để đưa pix về mode
unprivileged
pixfirewall> ?
ð để xem những lệnh nào có thể dùng được ở mode
này .
pixfirewall#configure terminal
pixfirewall(config)#
ð Pix đang ở trong mode configuration , tại đây ta có thể cấu
hình mọi thứ cho PIX .
ð Tất cả câu lệnh sử dụng ở hai mode unprivileged và
privileged đều có thể được sử dụng ở mode này .

Trước khi vào cấu hình sử dụng show run command để xem cấu
hình mặc định của PIX
pixfirewall# sh run => hoặc có thể sử dụng write terminal
command để xem
