Preface

The VPN Concentrator provides an HTML-based graphic interface, called the VPN Concentrator Manager, that allows you to configure, administer, and monitor your device easily. The VPN Concentrator Manager has three sets of screens that correspond to these tasks: Configuration screens, Administration screens, and Monitoring screens.

VPN 3000 Series Concentrator Reference Volume II: Administration and Monitoring is the second in the two volume VPN 3000 Series Concentrator Reference. Together, both volumes document all the screens of the VPN Concentrator Manager.

VPN 3000 Series Concentrator Reference Volume I: Configuration explains how to start and use the VPN Concentrator Manager. It details the Configuration screens and explains how to configure your device beyond the minimal parameters you set during quick configuration.
VPN 3000 Series Concentrator Reference Volume II: Administration and Monitoring provides guidelines for administering and monitoring the VPN Concentrator. It explains and defines all functions available in the Administration and Monitoring screens of the VPN Concentrator Manager. Appendixes to this manual provide troubleshooting guidance and explain how to access and use the alternate command-line interface.

This manual contains only administration and monitoring information. It does not contain any information about configuring the VPN Concentrator. For configuration information, refer to VPN 3000 Series Concentrator Reference Volume I: Configuration.

This manual also contains no information about installing the VPN Concentrator and initially configuring it. For information about set-up and initial configuration, refer to VPN 3000 Series Concentrator Getting Started.

Audience

We assume you are an experienced system administrator or network administrator with appropriate education and training, who knows how to install, configure, and manage internetworking systems. However, virtual private networks and VPN devices might be new to you. You should be familiar with Windows system configuration and management, and you should be familiar with Microsoft Internet Explorer or Netscape Navigator or Communicator browsers.

Prerequisites

We assume you have read the VPN 3000 Series Concentrator Getting Started manual, set up your VPN Concentrator, and followed the minimal configuration steps in quick configuration.

Organization

Note This guide is the second volume of the complete VPN Concentrator Manager reference. It documents only administration and monitoring tasks. For information on configuring your VPN Concentrator, refer to VPN 3000 Series Concentrator Reference Volume I: Configuration.

The chapters and sections of this guide correspond to the Administration and Monitoring parts of the VPN Concentrator Manager table of contents (the left frame of the Manager browser window) and are in the same order they appear there.

This guide has two parts:

Part 1, "Administration," explains and defines all functions available in the Administration screens of the VPN Concentrator Manager.
Part 2, "Monitoring," explains and defines all functions available in the Monitoring screens of the VPN Concentrator Manager.

This guide is organized as follows:

Chapter	Title	Explains How To...
Part One	Administration
Chapter 1	Administration	Access the Administration screens.
Chapter 2	Administer Sessions	View statistics for all active sessions, to test if particular sessions are active, and to terminate sessions.
Chapter 3	Software Update	Update both the VPN Concentrator system software and the VPN Client software.
Chapter 4	System Reboot	Reboot or shutdown the system.
Chapter 5	Ping	Test network connectivity.
Chapter 6	Monitoring Refresh	Set the status and statistics screens to refresh automatically.
Chapter 7	Access Rights	Configure and control administrative access to the VPN Concentrator.
Chapter 8	File Management	Manage files on the VPN Concentrator. It describes how to copy, view, and delete system files; how to swap backup and boot configuration files; and how to transfer files to and from the VPN Concentrator using TFTP, or to the VPN Concentrator using HTTP.
Chapter 9	Certificate Management	Enroll and install digital certificates automatically (using Simple Certificate Enrollment Protocol, SCEP) or manually. It describes how to manage installed certificates, for example, how to view, delete, and renew them. It also explains how to enable digital certificates on the VPN Concentrator.
Part Two	Monitoring
Chapter 10	Monitoring	Access the Monitoring screens.
Chapter 11	Routing Table	View routing statistics.

Data Formats

As you configure and manage the system, enter data in the following formats unless the instructions indicate otherwise:

Type of Data	Format

Technical Assistance Center

The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Cisco TAC inquiries are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

http://www.cisco.com/register/

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, please have available your service agreement number and your product serial number.
