Configuring Session Management

Configuring Session Management
You can use session management to track user sessions, and/or allocate dynamic resources to users for
the lifetime of their sessions. You can define one or more Session Managers, and have each one manage
the sessions for a particular group or company.

Configuring a Resource Manager

Session Managers use Resource Managers, which in turn manage a pool of resources of a particular type.
The Resource Managers have the following types:
•

Each Resource Manager is responsible for examining the request and deciding whether to allocate a
resource for the user, pass the request through, or cause Cisco AR to reject the request.

IP-Dynamic—manages a pool of IP address and allows you to dynamically allocate IP addresses
from that pool of addresses
IP-Per-NAS-Port—allows you to associate NAS ports to specific IP addresses, and thus ensure
specific NAS ports always get 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 after 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 after the configured limit has been reached
USR-VPN—allows you to set up a Virtual Private Network (VPN) using a US Robotics NAS. (A
Virtual Private Network is a way for companies to use the Internet to securely transport private data.)
IP address pool—allows you to manage pool of dynamic IP addresses
