Session Management Using Resource Managers

Chapter 2 Understanding Cisco Access Registrar

Cisco Access Registrar Hierarchy

For example, to use Services for authentication:

•When you want the authentication to be performed by the Cisco Access Registrar RADIUS server, you can specify the local service. In this, case you must specify a specific UserList.

•When you want the authentication performed by another server, which may run an independent application on the same or different host than your RADIUS server, you can specify either a radius, ldap, or tacacs-udpservice. In this case, you must list these servers by name.

When you have specified more than one authentication service, Cisco Access Registrar determines which one to use for a particular Access-Request by checking the following:

•When an incoming script has set the Environment dictionary variable Authentication-Servicewith the name of a Service, Cisco Access Registrar uses that service.

•Otherwise, Cisco Access Registrar uses the default authentication service. The default authentication service is a property of the Radius object.

Cisco Access Registrar chooses the authentication service based on the variable Authentication-Service, or the default. The properties of that Service, specify many of the details of that authentication service, such as, the specific user list to use or the specific application (possibly remote) to use in the authentication process.

For more information about Services, refer to Access Registrar Server Objects in the Cisco Access Registrar User’s Guide.

Session Management Using Resource Managers

Cisco Access Registrar lets you track user sessions, and/or allocate dynamic resources to users for the lifetime of their session. You can define one or more Session Managers, and have each one manage the sessions for a particular group or company.

Session Managers use Resource Managers, which in turn manage resources of a particular type as described below.

•IP-Dynamic—manages a pool of IP addresses and allows you to dynamically allocate IP addresses from that pool

•IP-Per-NAS-Port—allows you to associate ports to specific IP addresses, and thus ensure each NAS port always gets the same IP address

•IPX-Dynamic—manages a pool of IPX network addresses

•Group-Session-Limit—manages concurrent sessions for a group of users; that is, it keeps track of how many sessions are active and denies new sessions once the configured limit has been reached

•User-Session-Limit—manages per-user concurrent sessions; that is, it keeps track of how many sessions each user has and denies the user a new session once the configured limit has been reached

•USR-VPN—manages Virtual Private Networks (VPNs) that use USR NAS Clients.

For more information about Session Managers, refer to Access Registrar Server Objects in the Cisco Access Registrar User’s Guide.

If necessary, you can create a complex relationship between the Session Managers and the Resource Managers.

When you need to share a resource among Session Managers, you can create multiple Session Managers that refer to the same Resource Manager. For example, if one pool of IP addresses is shared by two departments, but each department has a separate policy about how many users can be logged in
