Installing the Software and Configuration
This appendix describes how to install or upgrade the system software on the Cisco VPN 5000 concentrator and how to download or back up a text configuration file in Flash memory.
Note 
The software and the Main CVC must reside in Flash memory. Other CVC configurations can reside on a TFTP or LDAP server.
Downloading the Software to the Concentrator
The VPN 5002 and VPN 5008 concentrators use the same software file; the VPN 5001 concentrator uses a different software file.
You can download the software:
•With TFTP using the concentrator as a TFTP server
•With TFTP using the concentrator as a TFTP client
•With XModem on the console port
Using the Concentrator as a TFTP Server to Download Software
To download the software, follow these steps:
Step 1 Enable TFTP by entering the following command at a console or Telnet session:
tftp enable [timeout] [TFTP_client_IP_address]
•Timeout—The amount of time in seconds that TFTP is enabled after you enter the command. The default is 60 seconds.
•TFTP_client_IP_address—The IP address allowed to connect with TFTP to the concentrator. If you used Telnet to enter this command, the default is the Telnet host IP address. You must enter a value if you are using a console connected directly to the console port.
Step 2 Use a TFTP client on your PC to transfer the software file in binary mode before the tftp enable command times out.
The software file name can be any name. After you download the file, the concentrator restarts.
Note If you see the message, "Incorrect filename," on your TFTP client, you forgot to set the file type to binary.
Using the Concentrator as a TFTP Client to Download Software
To download the software from a TFTP server, follow these steps:
Step 1 Copy the software file into your TFTP server download directory (usually the tftpboot directory).
The software file name can be any name.
Step 2 On the concentrator, enter the following command at the prompt:
tftp get code TFTP_server remote_filename
•TFTP_server—The TFTP server IP address.
•Remote_filename—The software file name. The filename can include a directory path. For example:
tftp get code 10.1.1.1 /vpn5002_a/vpn-5002-5008-6.0.21-3des.dld
After you download the file, the concentrator restarts.
Downloading Software Through the Console Port
If the concentrator interface is not available for TFTP downloads, you can use XModem on the console port to download the software from an attached PC. To perform the download, follow these steps:
Step 1 Copy the software to the PC you want to connect to the console port.
Note If you are using HyperTerminal on Windows, we recommend that you browse to the file before initiating the transfer, then cancel the action. After you browse to the file, the file is the default location for the rest of the session. This action helps minimize the time to start the download after setting the VPN 5000 concentrator into receive mode so that a timeout does not occur.
Step 2 Connect the provided console cable (a standard RS-232 cable) from your PC to one of the following ports (Figure A-1):
•VPN 5002 or 5008—Console port on the ESP card in slot 0
•VPN 5001—AUX port
Figure A-1 Slot Numbering
Step 3 Set the terminal emulator to use the following settings:
•9600 Baud
•8 bits
•No parity
•1 stop bit
•No flow control
Step 4 Set the file transfer method to:
•Xmodem-1K
•Binary
•16-bit CRC mode
Step 5 Start the download by following the steps for one of the following options:
•To download software from the VPN 5000 concentrator prompt (available after starting up in the currently installed software):
a. At the prompt, enter:
Where baud is the rate at which to download the image. We recommend 115200 or the fastest rate supported by your terminal emulator.
The concentrator prompts you to set the PC terminal emulator baud rate to match the entered value.
b. Set the terminal emulator to the corresponding rate.
Note If you are using HyperTerminal on Windows, you must disconnect the COM connection before you are allowed to change the baud rate. You must reconnect for the new baud rate to take effect.
c. Press any key.
If you set the rates correctly, you see a readable confirmation string.
d. At the concentrator command line prompt, enter:
•To download software from the Boot-Block Downloader prompt (available if there is no software installed, or if you set the test switch to 3):
a. At the prompt, enter:
Where baud is the rate at which to download the image. We recommend 115200 or the fastest rate supported by your terminal emulator.
The concentrator prompts you to set the PC terminal emulator baud rate to match the entered value.
b. Set the terminal emulator to the corresponding rate.
Note If you are using HyperTerminal on Windows, you must disconnect the COM connection before you are allowed to change the baud rate. You must reconnect for the new baud rate to take effect.
c. Press any key.
If you set the rates correctly, you see a readable confirmation string.
Step 6 Initiate the transfer in the terminal emulator.
Step 7 The terminal emulator displays the file transfer progress. When finished, the concentrator reboots automatically.
Step 8 Reset the terminal emulator port rate to 9600 baud.
Copying a Text Configuration File
You can copy the configuration files to or from the concentrator by using the concentrator as a TFTP server or as a TFTP client. The following sections describe both methods.
The concentrator requires the Main CVC (main.cfg) to reside in Flash memory. You can also copy other CVCs to Flash memory using one of the following procedures.
Note The configuration space in Flash memory is 64 KB. If Flash memory is full, you must use a TFTP or LDAP server for additional configurations.
Using the Concentrator as a TFTP Server to Copy the Configuration
To download or upload the configuration, follow these steps:
Step 1 Enable TFTP by entering the following command at a console or Telnet session:
tftp enable [timeout] [TFTP_client_IP_address]
•Timeout is the amount of time in seconds that TFTP is enabled after entering the command. The default is 60 seconds.
•TFTP_client_IP_address is the IP address allowed to connect using TFTP to the concentrator. If you used Telnet to enter this command, the default is the Telnet host IP address. You must enter a value if you are using a console connected directly to the console port.
Step 2 Use a TFTP client on your PC to copy the configuration file in ASCII mode before the tftp enable command times out.
Specify a CVC file name (name.cfg) in your TFTP client to get or put. If you put the Main CVC on the concentrator, you can specify main.cfg, or vpn5002_8.cfg (for the VPN 5002 or 5008) or vpn5001.cfg (for the VPN 5001) as the source or destination file name. The concentrator automatically changes vpn500x.cfg to main.cfg when it stores it in Flash memory. After downloading the Main CVC, the concentrator restarts.
Note For a list of files in Flash memory, use the show contexts command. This command lists the URL for the file (for example, flash://context.cfg). The file name to specify in the TFTP client is context.cfg.
Using the Concentrator as a TFTP Client to Copy the Configuration
To download or upload the configuration to or from a TFTP server, follow these steps:
Step 1 To download, copy the configuration file, name.cfg, into your TFTP server file directory (usually the tftpboot directory).
To upload a file to some TFTP servers, a file with the same name must already exist, and its permissions must allow you to write over it.
Step 2 On the concentrator, enter the following command at the prompt:
tftp {get | put} config TFTP_server source_filename
[destination_filename]
•get—Downloads the file from the file directory. After you download the Main CVC, the concentrator restarts.
•put—Uploads the file to the file directory.
•TFTP_server—The TFTP server IP address.
•source_filename—The file you want to copy. You can specify main.cfg, or vpn5002_8.cfg (for the VPN 5002 or 5008) or vpn5001.cfg (for the VPN 5001) as the source or destination file name. The concentrator automatically changes vpn500x.cfg to main.cfg when it stores it in Flash memory. The filename can include a directory path. For example:
tftp get config 10.1.1.1 /vpn5002_a/vpn5002_8.cfg
•destination_filename—The new file name at the destination. For get, the file name is the CVC file name (name.cfg) specified in the Context List section. The filename can include a directory path. For example:
tftp get config 10.1.1.1 /vpn5002_a/vpn5002_8.cfg
