This appendix includes procedures for updating the software on the Catalyst 2900. 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:
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:
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 c2900_spvxx.bin, where xx is the software revision number.
Step 4 Log in to the Catalyst 2900 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. 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 c2900_spvxx.bin
Step 6 When the following prompt appears, press y:
The Catalyst 2900 erases the Flash code and reprograms modules on the supervisor card with the downloaded Flash code:
Step 7 Reset the Catalyst 2900.
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.
Follow the steps below for troubleshooting a failed serial download procedure:
Step 1 Make certain that the Catalyst 2900 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 2900 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. Refer to the section that most closely matches your configuration.
Perform the following steps before downloading software to the Catalyst 2900:
Step 1 Use a serial line to connect a PC serial port to the Catalyst 2900 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 c2900_spvxx.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 2900:
Kermit> set port comx
Step 6 At the Kermit> prompt, enter the following command to set the baud rate for the serial port:
set speed 9600
The default port speed for the Catalyst 2900 is 9600 baud.
 | Caution To prevent communication problems, do not use a speed greater than 19200 baud. |
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 2900:
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 the following 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 the following command to send the file to the Catalyst 2900 (where xx is the software revision number):
A message similar to the following appears, displaying the send status information:
Step 7 When the Kermit> prompt reappears, enter the command connect to return to the console prompt:
connect
Within the following two minutes, the following is displayed:
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.
Step 9 Reboot the Catalyst 2900 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 2900 matches the set line or set port command.
If you cannot communicate at all with the Catalyst 2900 and you are sure that the set line command is correct, check the serial port baud rate. The default baud rate of the Catalyst 2900 administration port is 9600. If the Catalyst 2900 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 19200 baud. |
