This appendix includes procedures for updating the software on the Catalyst 5000 series switch. New software to implement enhancements and maintenance releases is provided periodically. You can use one of these two methods to update the software:
Perform these steps to download software 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:
Make sure the /etc/services file contains the following line:
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 series switch through the administrative interface or through a Telnet session.
Step 5 Enter 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 download a software file for a Fiber Distributed Data Interface (FDDI) or Asynchronous Transfer Mode (ATM) module, you must also specify the module number to download a single module. If you do not specify a module number, the download command downloads an image based on the download header type. The following is the command syntax to download NMP images:
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:
The Catalyst 5000 series switch erases the Flash code, and reprograms modules on the supervisor card with the downloaded Flash code:
Step 7 Reset the Catalyst 5000 series switch.
Step 8 Enter 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 in the next section if the download failed.
Follow these steps to troubleshoot a failed serial download procedure:
Step 1 Make certain that the Catalyst 5000 series switch has a route to the TFTP server, and enter 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 series switch 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.
Using Kermit, you can download software using a PC or a Sun workstation. The following two sections describe each of these methods.
Perform these steps before downloading software to the Catalyst 5000 series switch:
Step 1 Use a serial line to connect a PC serial port to the Catalyst 5000 series switch 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 series switch:
Kermit>
set port com
x
Step 6 At the Kermit> prompt, enter this command to set the baud rate for the serial port:
set speed 9600
The default port speed for the Catalyst 5000 series switch is 9600 baud.
Caution To prevent communication problems, do not use a speed greater than 19,200 baud. |
To download the software from a PC, perform these steps:
Step 1 At the Kermit> prompt, enter the connect command to connect to the Catalyst 5000 series switch:
Kermit>
connect
If your line and speed are set correctly, the console prompt appears.
Step 2 Enter enable to enter privileged mode.
enable
Step 3 At the Kermit> prompt, enter the download serial command. The file is downloaded to module 1 by default:
Step 4 When this prompt appears, press y:
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 this command to send the file to the Catalyst 5000 series switch (where xx is the software revision number):
Kermit>
send c5009_
xx
.bin
A message similar to the following appears, displaying the send status information:
c5009_xx.bin
Step 7 When the Kermit> prompt reappears, enter the connect command to return to the console prompt:
connect
Within two minutes, the following is displayed:
Step 8 Enter 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 in the next section if the download failed.
Step 9 Reboot the Catalyst 5000 series switch to initialize Flash memory.
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 series switch matches the set line or set port command.
If you cannot communicate with the Catalyst 5000 series switch 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 series switch administration port is 9600. If the Catalyst 5000 series switch baud rate was changed to an unknown value, you might 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 most common problem with Kermit file transfers is an incorrect line setting. Make sure that the serial port on the Sun workstation or PC connected to the Catalyst 5000 series switch matches the set line or set port commands.
If you cannot communicate with the Catalyst 5000 series switch 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 series switch administration port is 9600. If the Catalyst 5000 series switch baud rate was changed to an unknown value, you might 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. |
On a Sun workstation, make sure that the shell window you are using is a local window (not an rlogin window to a different workstation).
During a successful file transfer, a dot appears on the screen for every four packets transferred. If Kermit has trouble transferring the file, other code letters can appear.
