The Cisco VPN 3000 Concentrator devices are a series of
specialty appliances that perform VPN gateway services for organizations of all
sizes. The VPN Concentrator can be used in remote access implementations,
providing secure connections for mobile users and Small Office/Home Office
(SOHO) locations, as well as LAN-to-LAN connections providing VPN access between
branch locations. Many networks use the Concentrators for both types of
networks.
Concentrator configuration and operations are via a menu-driven
architecture, accessed by either a text-based CLI or a web-based interface.
Generally, all tasks and functions can be performed using either interface, but
the CLI must be used initially to configure an IP address on the private
interface to allow web access.
The Concentrator functions and menu options break into three
areas: Configuration, Administration, and Monitoring. Configuring the system
sets the parameters that govern its use and functionality as a VPN device, but
administration involves higher level activities, such as who is allowed to
configure the system and what software runs on it. The Monitoring screens can be
used to view the status of the many processes and activities essential to system
administration and management, as well as the statistics the Concentrator
compiles.
