IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.5 377
RADIUS and TACACS+ Appendix A
A
Introduction
This chapter describes the parameters that can be passed to the IOLAN when a user logs into the
IOLAN (serial port set to profile
Terminal) from external authentication RADIUS and TACACS+
servers.
RADIUS
Although RADIUS can be used strictly for external authentication, it can also be used to configure
line and user parameters. Therefore, when a user is being authenticated using RADIUS, it is possible
that the user’s configuration is a compilation of the parameters passed back from RADIUS, the
IOLAN parameters if the user has also been set up as a local user in the IOLAN, and the Default
User’s parameters for any parameters that have not been set by either RADIUS or the user’s local
configuration.
Supported RADIUS Parameters
This section describes the attributes which will be accepted by the IOLAN from a RADIUS server in
response to an successful authentication request.
Type Name Description
1 User-Name Request The name of the user to be authenticated.
2 User-Password Request The password of the user to be authenticated.
4 NAS-IP-Address Response The IOLAN’s IPV4 address.
5 NAS-Port Response If the user is connected to a physical port then the
port number of the port is sent. If the user is
connected to the IOLAN itself then a port number
of 0 is sent.
