Chapter 16 Configuring RADIUS Features
RADIUS Attribute 31: PPPoX Calling Station ID
Table 16-2 describes the Calling-Station-ID attribute fields.
Note The RADIUS logical line ID allows operators to download the Calling-Station-ID from RADIUS during
the preauthentication phase. The RADIUS Logical Line ID feature allows a download of the attribute at
session start time. You should not use the RADIUS Logical Line ID feature with the RADIUS Attribute
31: PPPoX Calling Station ID feature; using both features causes two instances of the attribute in the
RADIUS IOS database for a particular user.
Restrictions for PPPoX Calling Station ID
The following restrictions apply to the RADIUS Attribute 31: PPPoX Calling Station ID feature:
• Do not use the RADIUS Logical Line ID feature with the RADIUS Attribute 31: PPPoX Calling
Station ID feature. Using both features causes two instances of the attribute in the RADIUS IOS
database for a particular user.
• While this feature can be used with any vendor's RADIUS server, some RADIUS servers can require
modifications to their dictionary files to allow the Calling-Station-ID attribute to be presented
correctly in the RADIUS logs.
• This feature supports only RADIUS; TACACS+ is not supported.
• Currently, PPPoEoVLAN and PPPoEoQinQ do not provide information on VLAN tags; only the
MAC address is provided to the RADIUS server.
• RADIUS attribute 31 (Calling-Station-ID) is not supported for L2TP Network Server (LNS)
environments. If you enable this attribute on an LNS, the attribute is not sent to the RADIUS server.
