Configuring Cisco Access Registrar 4.2
This chapter describes how to configure a site. Cisco Access Registrar 4.1 is very flexible. You can
choose to configure it in many different ways. In addition, you can write scripts that can be invoked at
different points during the processing of incoming requests and/or outgoing responses.
Before you can take advantage of this flexibility, it helps to configure a simple site. This chapter
describes that process. It specifically describes a site that has the following characteristics:
• Uses a single user list for all of its users
• Writes all of its accounting information to a file
• Does not use session management to allocate or track dynamic resources
This chapter contains the following sections:
• Using aregcmd, page 4-1
• Configuring a Basic Site, page 4-2
• Configuring SNMP, page 4-14
Using aregcmd
To configure Cisco AR, use the aregcmd commands, which are command-line based configuration tools.
These commands allow you to set any Cisco AR configuration option, as well as, start and stop the Cisco
AR RADIUS server and check its statistics.
General Command Syntax
Cisco AR stores its configuration information in a hierarchy. Using the aregcmd command cd (change
directory), you can move through this information in the same manner as you would through a
hierarchical file system. Or you can supply full pathnames to these commands to affect another part of
the hierarchy, and thus avoid explicitly using the cd command to change to that part of the tree.
The aregcmd commands are case insensitive, which means that you can use upper or lowercase letters
to designate elements. In addition, when you reference existing elements in the configuration, you only
need to specify enough of the element’s name to distinguish it from the other elements at that level. For
example, instead of entering cd Administrators, you can enter cd ad if no other element at the current
level begins with ad.
