Configuring RADIUS Features
RADIUS Attribute 31: PPPoX Calling Station ID
The RADIUS Attribute 31: PPPoX Calling Station ID feature enables service providers to provide more
information about the call originator to the RADIUS server in a DSL environment, such as the physical
lines on which customer calls originate. Specifically, this feature allows operators to track customers
through the physical lines on which customer calls originate. Service providers can better maintain the
profile database of their customers as they move from one physical line to another.
Because this feature provides a virtual port that does not change as customers move from one physical
line to another, RADIUS attribute 31 (Calling-Station-ID) can also be used for additional security
checks. The Calling-Station-ID attribute is included in both ACCESS-REQUEST and
ACCOUNTING-REQUEST messages.

Calling-Station-ID Formats
The Calling-Station-ID attribute has 2 formats: Nas-Port and MAC-only. For Nas-Port, the system
provides to the RADIUS server the host name and domain name of the node, an interface description,
and VPI/VCI information (when the session is ATM-based, such as PPPoA or PPPoEoA). The MAC
address is provided for PPPoEoE sessions instead of the VPI and VCI information that is provided for
ATM-based sessions. For MAC-only, only the MAC address is specified for PPPoEoE sessions.
Table 16-1
MAC-only and Nas-Port types of Calling-Station-ID are enabled, the system provides only the MAC
address to the RADIUS server for PPPoEoE sessions.
