IEEE 802.1X Authentication for IP Phones
The 5215 Dual Mode, 5220 Dual Mode, and 5235 IP Phones support IEEE
802.1X Extensible Authentication Protocol (EAP) -Message Digest 5
(MD5) Challenge authentication protocol. Refer to the 3300 ICP
Engineering Guidelines for more information about this protocol.
If the network switches and their ports support 802.1.x authorization, the
Remote Authentication Dial-In User Service (RADIUS) server checks the
username and password of the IP phones against the entries in the
database:
• If the username and password of the IP phone match the username
and password on the RADIUS server, the IP phone is granted access
to the port services. The IP phone boots up.
• If the username and password don’t match, the IP phone is denied port
access. The IP phone does not boot up.
• If a username and password are not configured for the IP phone, you
are prompted to enter them.
Configuring an Authentication Username and Password
1. Power up or reboot the 5215 Dual Mode, 5220 Dual Mode, or 5235 IP
Phone.
2. Wait for the prompt: PORT ACCESS CONTROL
PRESS # TO CONTINUE.
Tip: Restoring the factory default settings on the 5215 or 5220 IP Phone
(Dual Mode) will erase the static network parameters.
