7.3.8 Authentication Timed Out in Campus Network
Symptom
There were six buildings in the student dormitory of school A. If students wanted to access
the Internet, their computers must pass the authentication and accounting system. The
Radius server software and Bras hardware devices of the authentication and accounting
system were provided by company B. The DOT1X port authentication function must be
enabled on the access layer device ZXR10 2900E and it works with the authentication
and accounting system of company B to provide authentication and accounting services
for the students.
Company B completed the debugging of the Radius server and Bras devices and
allocated the authentication and accounting clients to each building for installation. Most
students registered and activated their accounts. After the preparation was completed,
ZTE's maintenance engineers enabled the DOT1X function on the access layer devices
of the six buildings, as required by the customer. The configuration of the ZXR10 2900E
was as follows:
Two devices connected to two ports in the same VLAN cannot ping each other.
