Downloading Files

This appendix includes procedures for updating the software on the Catalyst 5000 series switch. New software to implement enhancements and maintenance releases will be provided periodically. You can use one of the following two methods to update the software:

Initiate the network download from the Catalyst 5000 through a Trivial File Transfer Protocol (TFTP) server. This is the fastest and easiest method.
Use Kermit (a popular file-transfer and terminal-emulation software program) to perform a serial software download from a PC or workstation.

Downloading Software Using TFTP

Perform the following steps to download software from a console, using TFTP:

Step 1 Make sure the workstation acting as the download server has the TFTP daemon.

Step 2 On Sun workstations, make sure the /etc/inetd.conf file contains the following line:


tftp dgram udp wait root /usr/etc/in.tftpd in.tftpd -p -s /tftpboot

Make sure the /etc/services file contains the following line:


tftp 69/udp

Note You must restart the inetd daemon after modifying the /etc/inetd.conf and /etc/services files. To restart the daemon, either kill the inetd process and restart it, or issue a fastboot command (on the SunOS 4.x) or a reboot command (on Solaris 2.x or SunOS 5.x). Refer to your workstation manual for use of TFTP daemons.

Step 3 Copy the new software from the floppy disks to the home directory specified for the TFTP daemon on the workstation (usually /tftpboot). If this directory does not exist, create it before continuing. The file you copy is c5009_xx.bin, where xx is the software revision number.

Step 4 Log in to the Catalyst 5000 through the administrative interface or through a telnet session.

Step 5 Use the download host file command. Specify the IP address or host name of the workstation acting as the download server. Also specify the file to download. If you are downloading a software file for an FDDI or ATM module, you must also specify the module number. The following is the command syntax:

download host file [module num]

In the following example, no module number is given, so the file is downloaded to module 1 by default:


Console>

(enable)


download 190.180.122.40 c5009_11xx.bin

Step 6 When the following prompt appears, press y:


Download image

filename from IP address to Module 1? (y/n) [n]? y

Note While the software is downloading, the Fan, PS1 and PS2 LEDs on the left side of the supervisor module blink green, and the Catalyst 5000 remains operational.

The Catalyst 5000 erases the Flash code, and reprograms modules on the supervisor card with the downloaded Flash code:

The system needs to be reset to run the new image.

Step 7 Reset the Catalyst 5000.

Step 8 Use the show flash command to check the file you have just downloaded. If the version number is the correct number for the new software, the download was successful. If the version number is not the correct number, the download failed, and you must repeat the download procedure. Refer to the troubleshooting procedures below if the download failed.

Troubleshooting the TFTP Download Procedure

Follow the steps below for troubleshooting a failed serial download procedure:

Step 1 Make certain that the Catalyst 5000 has a route to the TFTP server, and use the ping command to test this connectivity.

Step 2 Make certain that the software image to be downloaded is in the correct directory.

The network portion of the Catalyst 5000 IP address must be the same as the network portion of the TFTP server address. If the network download procedure fails because the power was interrupted during the download procedure, or for some other reason, the Flash code can become corrupted and the boot> prompt appears on the administration port. In that case, you can use the network download procedure to download the Flash code again through an enabled port in VLAN 1. By default, only port 1/1 is enabled. You can use port 1/1 or enable another port.

Downloading Software from a Serial Port

Using Kermit, you can download software using a PC or a Sun Workstation. The following two sections describe each of these methods. Refer to the section that most closely matches your configuration.

Downloading Software to the Catalyst 5000 Using a PC

Perform the following steps before downloading software to the Catalyst 5000:

Step 1 Use a serial line to connect a PC serial port to the Catalyst 5000 supervisor engine module console port.

Step 2 Install Kermit on the PC.

Step 3 Copy the new software from the floppy disk to the directory where Kermit is loaded. The file you copy is c5009_xx.bin, where xx is the software revision number.

Step 4 Start Kermit on the PC.

Step 5 At the Kermit> prompt, specify the serial port using the following command, where x is the serial port number (1 through 8) that you connected to the Catalyst 5000:


Kermit> set port comx

Step 6 At the Kermit> prompt, enter the following command to set the baud rate for the serial port:


Kermit> set speed 9600

The default port speed for the Catalyst 5000 is 9,600 baud.

Caution To prevent communication problems, do not use a speed greater than 19,200 baud.

Note To change the line speed for the file transfer, first use the set system baud command on the Catalyst 5000, then escape back to Kermit to execute a set speed command.

Downloading the New Software

To download the software from a PC, perform the following steps:

Step 1 At the Kermit> prompt, enter the following command to connect to the Catalyst 5000:


Kermit> connect

If your line and speed are set correctly, the console prompt appears.

Step 2 Enter enable to enter privileged mode.


Console> enable


Console> (enable)

Step 3 At the Kermit> prompt, enter the download serial command. The file is downloaded to module 1 by default:


Kermit> (enable) download serial

Step 4 When the following prompt appears, press y:


Download CBI image via console port (y/n) [n]? y


Waiting for DOWNLOAD!


Return to your local Machine by typing its escape sequence


Issue Kermit send command from there[ Send `Filename`]

Step 5 Enter the escape sequence Ctrl-]-c

To enter this sequence correctly, hold down the Control key while you press ] and then press c.

Step 6 At the Kermit> prompt, enter the following command to send the file to the Catalyst 5000 (where xx is the software revision number):


Kermit> send c5009_xx.bin

A message similar to the following appears, displaying the send status information:

The system needs to be reset to run the new image.

Note If you use the connect command more than two minutes after the Kermit> prompt reappears, you may only see a console prompt instead of the status information shown above.

Step 9 Reboot the Catalyst 5000 to initialize Flash memory.

Troubleshooting the PC Download Procedure

The most common problem with Kermit file transfers is an incorrect line setting. Make sure that the serial port on the PC connected to the Catalyst 5000 matches the set line or set port command.

If you cannot communicate at all with the Catalyst 5000 and you are sure that the set line command is correct, check the serial port baud rate. The default baud rate of the Catalyst 5000 administration port is 9,600. If the Catalyst 5000 baud rate was changed to an unknown value, you may have to enter several set speed commands in Kermit before you can make a connection.

Caution To prevent communication problems, do not use a speed greater than 19,200 baud.

The following list identifies the Kermit error codes:

T---Kermit timed out.
N---Kermit is not acknowledging (NAK) the Catalyst 5000 download process.
E---Kermit detected an error in the progress of the transaction.
