Network requirements
■ A user running 802.1x authentication client accesses the Internet through a
switch. The user can access external networks after passing the authentication.
The accounting mode is traffic accounting. When the user accesses the
networks 11.127.1.0/24 and 12.127.1.0/24, the accounting server CAMS
charges the user according to the user’s online traffic. When the user accesses
other networks, however, the user is not charged.
