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.
