Working With System Software Images

This chapter describes how to how to work with system software image files.

Note   For complete syntax and usage information for the commands used in this chapter, refer to the Command Reference for your switch.

This chapter consists of these sections:

•Uploading System Software Images to a TFTP Server

Downloading System Software Images to the Switch

These sections describe how to download system software images to the switch supervisor engine and to intelligent modules:

•Understanding How Software Image Downloads Work

•Downloading Software Images Using TFTP

•Downloading Software Images Over a Serial Connection on the Console Port

Understanding How Software Image Downloads Work

You can download system software images to switch using one of two methods:

•Trivial File Transfer Protocol (TFTP)—You can use TFTP to perform a network download of files from a TFTP server

•Kermit—You can use Kermit, a popular file-transfer and terminal-emulation software program, to perform a serial transfer of files over the supervisor engine console port

Some modules, such as Catalyst 5000 series FDDI and ATM modules, have their own onboard Flash. When you download a software image file, the switch checks the header of the image file to determine the type of software image.

Depending on the type of software image you are downloading, one of the following occurs:

•Supervisor engine software image—The image file is downloaded to the supervisor engine Flash memory. On the Catalyst 5000 series Supervisor Engine I or II and on the Catalyst 2926 series switches, you can store only a single image file at a time. On the Catalyst 5000 series Supervisor Engine III, III FSX, and III FLX, and on the Catalyst 4000, 2948G, and 2926G series switches, you can store multiple image files on the Flash memory system devices (such as boot Flash and, on the Supervisor Engine III, Flash PC cards).

Caution   Some supervisor engine software releases update the supervisor engine erasable programmable logic devices (EPLDs). The EPLDs can be updated only a limited number of times. You should avoid loading a new software release and then backing out unnecessarily. The supervisor engine software release notes indicate which software releases have code that updates the EPLDs.

•Intelligent module software images—If you specified a module number, the image file is downloaded to the specified module only (provided the image file is designed for the specified module type). If you do not specify a module number, the image file is downloaded to every module of the appropriate type. The file is relayed packet by packet to the appropriate modules using the Inter-Process Communications (IPC) protocol internal to the system, with communication taking place across the switching bus. Downloading a software image to multiple modules significantly speeds up the process of updating the software on multiple modules of the same type.

Downloading Software Images Using TFTP

The following sections describe how to download software images to the switch using TFTP:

•Preparing to Download an Image Using TFTP

•Downloading Supervisor Images Using TFTP

•Downloading Switching Module Images Using TFTP

•Example TFTP Download Procedures

Note   For more information on working with system software image files on the Flash file system, refer to "."

Preparing to Download an Image Using TFTP

Before you begin downloading a software image using TFTP, make sure of the following:

•Ensure that the workstation acting as the TFTP server is configured properly. On a Sun workstation, make sure that 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 that the /etc/services file contains this 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 stop the inetd process and restart it, or enter a fastboot command (on the SunOS 4.x) or a reboot command (on Solaris 2.x or SunOS 5.x). Refer to the documentation for your workstation for more information on using the TFTP daemon.

•Ensure that the switch has a route to the TFTP server. The switch and the TFTP server must be in the same subnetwork if you do not have a router to route traffic between subnets. Check connectivity to the TFTP server using the ping command.

•Ensure that the software image to be downloaded is in the correct directory on the TFTP server (usually /tftpboot on a UNIX workstation).

•Ensure that the permissions on the file are set correctly. Permissions on the file should be world-read.

•A power interruption (or other problem) during the download procedure can corrupt the Flash code. If the Flash code is corrupted, you can connect to the switch through the console port. At the boot> prompt, you can download the Flash code again through an enabled port in VLAN 1. By default, port 1/1 is enabled. You can use port 1/1 or enable another port.

Downloading Supervisor Images Using TFTP

Note   Catalyst 5505, Catalyst 5509, and Catalyst 5500 only—If you have a redundant supervisor engine, you cannot download a system image directly from a TFTP server to the Flash memory on the standby supervisor engine. When you download the image to the active supervisor, the standby supervisor sychronizes automatically with the new image. In addition, you cannot copy an image from the standby supervisor engine to the active supervisor engine.

Use the following procedure to download a supervisor engine software image to the switch from a TFTP server:

Step 1 Copy the software image file to the appropriate TFTP directory on the workstation.

Step 2 Log into the switch through the console port or through a Telnet session. If you log in using Telnet, your Telnet session disconnects when you reset the switch to run the new software.

Step 3 Use the command appropriate for your switch and supervisor engine to download the software image from the TFTP server:

•Catalyst 5000 series Supervisor Engine I or II, and Catalyst 2926 series switches—Use the download host file command, where host is the IP address or host name of the workstation acting as the TFTP server and file is the name of the file to download.

•Catalyst 5000 series Supervisor Engine III, III FSX, and III FLX, and Catalyst 4000, 2948G, and 2926G series switches—Use the copy tftp flash command. When prompted, enter the IP address or host name of the TFTP server, the name of the file to download, the Flash device to which to copy the file, and the destination filename.

Note   The Supervisor Engine III FSX and FLX models, and the Catalyst 4000 and 2948G series switches have only one Flash device (bootflash:).

The switch downloads the image file from the TFTP server:

•Catalyst 5000 series Supervisor Engine I or II, and Catalyst 2926 series switches—The Flash memory on the supervisor engine is erased and reprogrammed with the downloaded Flash code.

•Catalyst 5000 series Supervisor Engine III, III FSX, and III FLX, and Catalyst 4000, 2948G, and 2926G series switches—The image is copied to the specified Flash device.

Note   The switch remains operational while the image downloads.

Step 4 Catalyst 5000 series Supervisor Engine III, III FSX, and III FLX, and Catalyst 4000, 2948G, and 2926G series switches—Modify the BOOT environment variable using the set boot system flash device:filename prepend command, so that the new image boots when you reset the switch. Specify the Flash device (device:) and the filename of the downloaded image (filename).

Note   This step is not necessary on the Catalyst 5000 series Supervisor Engine I or II, and on the Catalyst 2926 series switches.

Step 5 Reset the switch using the reset system command. If you are connected to the switch through Telnet, your Telnet session disconnects.

During startup, on the Catalyst 5000 series Supervisor Engine III, III FSX, and III FLX, and on the Catalyst 4000, 2948G, and 2926G series switches, the Flash memory on the supervisor engine is reprogrammed with the new Flash code.

Step 6 When the switch reboots, enter the show version command to check the version of the code on the switch.

Note   For examples that show complete TFTP download procedures for the various supervisor engine and switch types, see the "Example TFTP Download Procedures" section.

Downloading Switching Module Images Using TFTP

Use this procedure to download a software image to an intelligent module on a Catalyst 5000 series switch:

Step 1 Copy the software image file to the appropriate TFTP directory on the workstation.

Step 2 Log into the switch through the console port or a Telnet session. If you log in using Telnet, your Telnet session might disconnect when you reset modules to run the new software.

Step 3 Use the command appropriate for your switch and supervisor engine to download the software image from the TFTP server:

•Catalyst 5000 series Supervisor Engine I or II, and Catalyst 2926 series switches

–If there is only one module of the type appropriate for the image, or if there are multiple modules of the same type and you want to update the image on all of them, use the download host file command, where host is the IP address or host name of the TFTP server and file is the name of the file to download.

–If there are multiple modules of the type appropriate for the image but you only want to update a single module, use the download host file mod_num command, where mod_num is the slot in which the module is installed.

Note   If you do not specify a module number, the switch examines the header of the image file to determine to which modules the software is downloaded. The image is then downloaded to all the modules of that type.

•Catalyst 5000 series Supervisor Engine III, III FSX, and III FLX, and Catalyst 4000, 2948G, and 2926G series switches

–If there is only one module of the type appropriate for the image, or if there are multiple modules of the same type and you want to update the image on all of them, use the copy tftp flash command. When prompted, enter the IP address or host name of the TFTP server, the name of the file to download, the Flash device to which to copy the file, and the destination filename.

–If there are multiple modules of the type appropriate for the image but you only want to update a single module, use the copy tftp m/bootflash: command, where m is the number of the module to which to download the software image.

The switch downloads the image file, erases the Flash memory on the appropriate modules, and reprograms the Flash memory with the downloaded Flash code.

Note   All modules in the switch remain operational while the image downloads.

Step 4 Reset the appropriate modules using the reset mod_num command. If you are connected through Telnet, your Telnet session disconnects if you reset the module through which your connection was made.

Step 5 When the upgraded modules come online, enter the show version [mod_num] command to check the version of the code on the switch.

Note   For examples that show complete procedures for TFTP downloads to intelligent modules, see the "Example Single Intelligent Module Image TFTP Download (Catalyst 5000 Series Supervisor I and II)" section, the "Example Multiple Module Image TFTP Download (Supervisor I and II)" section, the "Example Single Module Image TFTP Download (Supervisor III, III FSX, or III FLX)" section and the "Example Multiple Module Image TFTP Download (Supervisor III, III FSX, or III FLX)" section.

Downloading Software Images Over a Serial Connection on the Console Port

These sections describe how to perform a serial download of software images over the supervisor engine console port using Kermit:

•Preparing to Download an Image Using Kermit

•Downloading Software Images Using Kermit (PC Procedure)

•Downloading Software Images Using Kermit (UNIX Procedure)

•Example Serial Software Image Download Procedures

Preparing to Download an Image Using Kermit

Before you begin a serial download of a software image using Kermit, make sure of the following:

•On a UNIX workstation, make sure your shell window is local (not an rlogin window to a different workstation).

•Ensure that the supervisor engine console port is connected to a serial port on your PC or workstation with a serial cable.

•Ensure that the Kermit software is installed on your PC or workstation.

•Ensure that the line speed settings are the same on the PC or workstation and on the switch:

•On the switch, you can change the console port speed by entering the set system baud rate command. The default baud rate is 9600 baud.

•On the PC or workstation, you can change the baud rate of the serial port by entering the set speed rate command at the Kermit> prompt.

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

•Ensure that Kermit is using the proper serial port.

•On a PC, specify the serial port using the set port comx command, where x is the PC serial port number (1 through 8) that you connected to the switch.

•On a UNIX workstation, specify the serial port using the set port /dev/ttyx command, where x is the serial port (a or b) that you connected to the switch.

Downloading Software Images Using Kermit (PC Procedure)

Note   This procedure applies to PC serial downloads only. For information on performing a serial download on a UNIX workstation, refer to the "Downloading Software Images Using Kermit (UNIX Procedure)" section.

Use this procedure to perform a serial download of a software image over the supervisor engine console port:

Step 1 Copy the software image file to the directory where Kermit is loaded.

Step 2 Start Kermit on the PC.

Note   Before continuing, ensure that the line speed is correct and that you have selected the proper serial line, as described in the "Preparing to Download an Image Using Kermit" section.

Step 3 At the Kermit> prompt, enter the connect command to connect to the switch. If your line and speed are set correctly, the switch Console> prompt appears.

Step 4 Enter the enable command to enter privileged mode.

Step 5 Enter the download serial command. The file is downloaded to module 1 by default.

Step 6 When prompted, confirm the download.

Step 7 Enter the escape sequence Ctrl-]-c by holding down the Control key while you press ], and then press c.

Step 8 At the Kermit> prompt, enter the send filename command to send the file to the switch.

The switch downloads the image file, erases the Flash memory on the supervisor engine or the appropriate module, and reprograms the Flash memory with the downloaded Flash code.

Note   The switch remains operational while the image downloads.

Step 9 When the Kermit> prompt reappears, enter the connect command to return to the switch Console> prompt. You will see status information as the switch erases and reprograms the Flash memory.

Note   If you enter the connect command more than two minutes after the Kermit> prompt reappears, you might see only a Console> prompt instead of the status information about erasing and programming Flash code.

Step 10 Reset the switch using the reset system command.

Step 11 When the switch reboots, enter the show version [mod_num] command to check the version of the code on the switch.

Note   For an example that shows a complete serial download procedure using Kermit on a PC, see the "Example PC Serial Download Procedure" section.

Downloading Software Images Using Kermit (UNIX Procedure)

Note   This procedure applies to UNIX serial downloads only. For information on performing a serial download on a PC, refer to the "Downloading Software Images Using Kermit (PC Procedure)" section.

Use this procedure to perform a serial download of a software image over the supervisor engine console port.

To copy the software to the workstation, log in as root, and perform these steps:

Step 1 Copy the software image file to your home directory.

Step 2 At the UNIX command prompt, start Kermit by entering the kermit command (make sure the directory where Kermit is installed in included in the $PATH environment variable on the workstation).

Note   Before continuing, ensure that the line speed is correct and that you have selected the proper serial line, as described in the "Preparing to Download an Image Using Kermit" section.

Step 3 At the C-Kermit> prompt, enter the connect command to connect to the switch. If your line and speed are set correctly, the switch Console> prompt appears.

Step 4 Enter the enable command to enter privileged mode.

Step 5 Enter the download serial command. The file downloads to module 1 by default.

Step 6 When prompted, confirm the download.

Step 7 Enter the escape sequence Ctrl-\-c by holding down the Control key while you press \, and then press c.

Step 8 At the Kermit> prompt, enter the send filename command to send the file to the switch.

You can monitor the progress of the download by pressing the a key at any time during the Kermit download. A dot appears onscreen for every four packets transferred. If there is a problem transferring the file, one or more of the following letter codes appear:

•T—Kermit timed out.

•N—Kermit is not acknowledging the switch download process.

•E—Kermit detected an error in the progress of the transaction.

The switch downloads the image file, erases the Flash memory on the supervisor engine or the appropriate module, and reprograms the Flash memory with the downloaded Flash code.

Note   The switch remains operational while the image downloads.

Step 9 Press Return to return to the C-Kermit> prompt. When the Kermit> prompt reappears, enter the connect command to return to the switch Console> prompt. You will see status information as the switch erases and reprograms the Flash memory.

Note   If you enter the connect command more than two minutes after the Kermit> prompt reappears, you might see only a Console> prompt instead of the status information about erasing and programming Flash code.

Step 10 Reset the switch using the reset system command.

Step 11 When the switch reboots, enter the show version [mod_num] command to check the version of the code on the switch.

Note   For an example that shows a complete serial download procedure using Kermit on a
UNIX workstation, see the "Example UNIX Workstation Serial Download Procedure" section.

Uploading System Software Images to a TFTP Server

These sections describe how to upload system software images from a switch to a TFTP server:

•Preparing to Upload an Image to a TFTP Server

•Uploading Software Images to a TFTP Server

Note For more information on working with system software image files on the Flash file system, see "."

Preparing to Upload an Image to a TFTP Server

Before you attempt to upload a software image to a TFTP server, do the following:

•Ensure that the workstation acting as the TFTP server is configured properly. On a Sun workstation, make sure that the /etc/inetd.conf file contains this line:
tftp dgram udp wait root /usr/etc/in.tftpd in.tftpd -p -s /tftpboot
Make sure that the /etc/services file contains this 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 stop the inetd process and restart it, or enter a fastboot command (on the SunOS 4.x) or a reboot command (on Solaris 2.x or SunOS 5.x). Refer to the documentation for your workstation for more information on using the TFTP daemon.

•Ensure that the switch has a route to the TFTP server. The switch and the TFTP server must be in the same subnetwork if you do not have a router to route traffic between subnets. Check connectivity to the TFTP server using the ping command.

•You might need to create an empty file on the TFTP server before uploading the image. To create an empty file, enter the touch filename command, where filename is the name of the file you will use when uploading the image to the server.

•If you are overwriting an existing file (including an empty file, if you had to create one), ensure that the permissions on the file are set correctly. Permissions on the file should be world-write.

Uploading Software Images to a TFTP Server

Use this procedure to upload a software image on a switch to a TFTP server for storage:

Step 1 Log into the switch through the console port or a Telnet session.

Step 2 Upload the software image to the TFTP server using the command appropriate for your switch and supervisor engine:

•Catalyst 5000 series Supervisor Engine I or II, and Catalyst 2926 series switches—Use the upload host filename [mod_num] command. Specify the number of the module from which to upload the image in the mod_num argument. You do not need to specify the module number if you are uploading the supervisor engine software image.

•Catalyst 5000 series Supervisor Engine III, III FSX, and III FLX, and Catalyst 4000, 2948G, and 2926G series switches—Use the copy flash tftp command. When prompted, specify the Flash device, source filename, TFTP server address, and destination filename. If desired, you can also use the copy file-id tftp command.

The software image is uploaded to the TFTP server.

This example shows how to upload the supervisor engine software image on a Catalyst 5000 series Supervisor Engine I or II, or a Catalyst 2926 series switch, to a TFTP server:
Console> (enable) upload 172.20.52.3 cat5000-sup.4-2-1.bin
