Working with System Software Images

This chapter describes how to how to work with system software image files on the Catalyst 6500 series switches.

Note For complete syntax and usage information for the commands used in this chapter, refer to the Catalyst 6500 Series Switch Command Reference publication.

This chapter consists of these sections:

•Software Image Naming Conventions

•Upgrading EPLD Images

•Downloading Software Images to the Switch With TFTP

•Uploading System Software Images to a TFTP Server

•Downloading System Software Images Using rcp

•Uploading System Software Images to an rcp Server

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

•Downloading a System Image Using Xmodem or Ymodem

Software Image Naming Conventions

The software images on the Catalyst 6500 series switches use the following naming conventions (software release 7.3(1) is used in the examples):

•7.3(1) Flash image (standard)—cat6000-sup2k8.7-3-1.bin

•7.3(1) Flash image (CiscoView)—cat6000-sup2cvk8.7-3-1.bin

•7.3(1) Flash image (Secure Shell)—cat6000-sup2k9.7-3-1.bin

•7.3(1) Flash image (Secure Shell and CiscoView)—cat6000-sup2cvk9.7-3-1.bin

Note The sup2cvk8, sup2k9, and sup2cvk9 designations are as follows: sup2cvk8 is a CiscoView image, sup2k9 is a Secure Shell image, and sup2cvk9 is a Secure Shell and CiscoView image.

Upgrading EPLD Images

Note Supervisor engine EPLD upgrades are supported only on Supervisor Engine 2. Nonsupervisor engine module (switching modules and service modules) EPLD upgrades are supported using Supervisor Engine 1 or Supervisor Engine 2.

The EPLD image for Supervisor Engine 2 is included in the Catalyst supervisor engine software image. The EPLD image for nonsupervisor engine modules is provided in a separate downloadable image.

Upgrading the Supervisor Engine EPLD Image

The supervisor engine EPLD upgrade is performed automatically when the switch is reset or power cycled. You can use the set system supervisor-update command to modify the EPLD upgrade process. By default, the supervisor engine EPLD upgrade is disabled. In the automatic mode, the system checks the version level of the bundled EPLD image and performs the upgrade if the bundled EPLD image version is greater than the existing version. If you specify the force keyword, the system upgrades the existing EPLD image with the bundled EPLD image regardless of the version level. After a forced upgrade, the configuration reverts back to the automatic default setting. The disable keyword disables the automatic EPLD upgrade process.

To upgrade the supervisor engine EPLD image, perform this task in privileged mode:

Task

Command

Step 1

Upgrade the supervisor engine EPLD image.

set system supervisor-update {automatic | disable | force}

Step 2

Verify the supervisor engine EPLD image upgrade.

show system supervisor-update

This example shows how to specify the automatic option for EPLD upgrades:
Console> (enable) set system supervisor-update automatic
Down-rev supervisor EPLD's will be re-programmed next reset. 
Console> (enable)
This example shows how to specify the force option for EPLD upgrades:
Console> (enable) set system supervisor-update force
Supervisor EPLD's will synchronize to the image bundle during the next reset.
Console> (enable) 
This example shows how to disable EPLD upgrades:
Console> (enable) set system supervisor-update disable
Supervisor EPLD update during reset is disabled.
Console> (enable) 
This example shows how to display the EPLD upgrade configuration:
Console> (enable) show system supervisor-update
Supervisor EPLD update: disabled
Console> (enable)
Upgrading Nonsupervisor Engine Module EPLD Images

Caution Do not power off or reset the switch or module during the upgrade process. Failure to do so could leave the module in an unusable state.

Note Before you begin the procedures in this chapter, make sure that you have downloaded the new EPLD upgrade image to the supervisor engine Flash memory (bootflash: or slot0:).

You can upgrade the nonsupervisor engine module EPLD image by using the download command with the epld keyword. If you enter the download epld file command without specifying a module, the new EPLD image is downloaded to all compatible modules where the new EPLD image version is greater than the existing version on the module. If you use the download epld file mod command with the force keyword, the existing EPLD image on a module is upgraded with the new EPLD image regardless of the existing version level.

To upgrade the EPLD on the nonsupervisor engine modules (switching modules and service modules), perform this task in privileged mode:

Task

Command

Step 1

Upgrade the nonsupervisor engine EPLD image.

download epld file

download epld file mod [force]

Step 2

Verify the EPLD upgrade process configuration.

show version epld mod

This example shows how to upgrade the EPLD image on the module in slot 5:
Console> (enable) download epld aq_cr128_art.bin 5 force

Downloading Software Images to the Switch With TFTP

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

•Understanding How TFTP Software Image Downloads Work

•Preparing to Download an Image Using TFTP

•Downloading Supervisor Engine Images Using TFTP

•Downloading Switching Module Images Using TFTP

•TFTP Download Procedures Example

Understanding How TFTP Software Image Downloads Work

You can download system software images to the switch using the Trivial File Transfer Protocol (TFTP). TFTP allows you to download system image files over the network from a TFTP server.

Some modules, such as ATM modules, have their own onboard Flash memory. 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. You can store multiple image files on the Flash memory system devices (such as boot Flash and Flash PC cards).

•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 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.

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

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 and boot from an uncorrupted system image on a Flash PC card.

Downloading Supervisor Engine Images Using TFTP

Note 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 engine, the standby supervisor engine synchronizes automatically with the new image. In addition, you cannot copy an image from the standby supervisor engine to the active supervisor engine.

To download a supervisor engine software image to the switch from a TFTP server, perform these steps:

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 Enter the copy tftp flash command. When prompted, enter the IP address or host name of the TFTP server and the name of the file to download. On those platforms that support the Flash file system, you are also prompted for the Flash device to which to copy the file and the destination filename.

The switch downloads the image file from the TFTP server to the specified Flash device.

Note The switch remains operational while the image downloads.

Step 4 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).

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, 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 "TFTP Download Procedures Example" section.

Downloading Switching Module Images Using TFTP

To download a software image to an intelligent module, perform these steps:

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 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, enter 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.

Step 4 If there are multiple modules of the type appropriate for the image but you only want to update a single module, enter the copy tftp m/bootflash: command, where m is the number of the module to which to download the software image.

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.

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

Step 6 When the upgraded modules come online, enter the show version [mod] 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 "Single Module Image TFTP Download Example" section and the "Multiple Module Image TFTP Download Example" 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 "Working With the Flash File System."

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 that 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 set to world-write.

Uploading Software Images to a TFTP Server

To upload a software image on a switch to a TFTP server for storage, perform these steps:

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

Step 2 Upload the software image to the TFTP server with the copy flash tftp command. When prompted, specify the TFTP server address and destination filename. On platforms that support the Flash file systems, you are first prompted for the Flash device and source filename. If desired, you can use the copy file-id tftp command on these platforms.

The software image is uploaded to the TFTP server.

This example shows how to upload the supervisor engine software image:

Downloading System Software Images Using rcp

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

•Preparing to Download an Image Using rcp

•Downloading Supervisor Engine Images Using rcp

•Downloading Switching Module Images Using rcp

•Example rcp Download Procedures

Preparing to Download an Image Using rcp

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

•Ensure that the workstation acting as the rcp server supports the remote shell (rsh).

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

•If you are accessing the switch through the console or a Telnet session without a valid username, make sure that the current rcp username is the one you want to use for the rcp download. You can enter the show users command to view the current valid username. If you do not want to use the current username, create a new rcp username using the set rcp username command. The new username will be stored in NVRAM. If you are accessing the switch through a Telnet session with a valid username, this username will be used and there is no need to set the rcp username.

•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 and boot from an uncorrupted system image on a Flash PC card.

Downloading Supervisor Engine Images Using rcp

To download a supervisor engine software image to the switch from an rcp server, perform these steps:

Step 1 Copy the software image file to the appropriate rcp 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 Download the software image from the rcp server by entering the copy rcp flash command. When prompted, enter the IP address or host name of the rcp server and the name of the file to download. On those platforms that support the Flash file system, you are also prompted for the Flash device to which to copy the file and the destination filename.

The switch downloads the image file from the rcp server.

Note The switch remains operational while the image downloads.

Step 4 Modify the BOOT environment variable by entering 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).

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

During startup, 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.

Downloading Switching Module Images Using rcp

To download a software image to an intelligent module on a Catalyst 6500 series switch, perform these steps:

Step 1 Copy the software image file to the appropriate rcp 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 Enter the command appropriate for your switch and supervisor engine to download the software image from the rcp server:

•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, enter the copy rcp flash command. When prompted, enter the IP address or host name of the rcp 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, enter the copy rcp | m/bootflash: command, where m is the number of the module to which to download the software image. If you do not specify the module, all modules of the same type will be updated.

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.

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 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] command to check the version of the code on the switch.

Uploading System Software Images to an rcp Server

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

•Preparing to Upload an Image to an rcp Server

•Uploading Software Images to an rcp Server

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

Preparing to Upload an Image to an rcp Server

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

•Ensure that the workstation acting as the rcp server is configured properly.

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

•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 set to write for the specific username.

Uploading Software Images to an rcp Server

To upload a software image on a switch to an rcp server for storage, perform these steps:

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

Step 2 Upload the software image to the rcp server using the copy flash rcp command. When prompted, specify the rcp server address and destination filename. On platforms that support the Flash file systems, you are first prompted for the Flash device and source filename. If desired, you can use the copy file-id rcp command on these platforms.

The software image is uploaded to the rcp server.

This example shows how to upload the supervisor engine software image to an rcp server:

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, which is a popular file-transfer and terminal-emulation software program:

•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 that 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, see the "Downloading Software Images Using Kermit (UNIX Procedure)" section.

To perform a serial download of a software image over the supervisor engine console port, perform these steps:

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 Ctrl 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 2 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] 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 "PC Serial Download Procedure Example" 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, see 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 that the directory where Kermit is installed is 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 Ctrl 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 that are 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 2 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] 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 "UNIX Workstation Serial Download Procedure Example" section.

Downloading a System Image Using Xmodem or Ymodem

When you need a system image on the switch, but the switch does not have network access and you do not have a software image on a Flash PC card, you can download an image from a local or remote computer (such as a PC, UNIX workstation, or Macintosh) through the console port using the Xmodem or Ymodem protocol.

Xmodem and Ymodem are common protocols that are used to transfer files and are included in applications such as Windows 3.1 (TERMINAL.EXE), Windows 95 (HyperTerminal), Windows NT 3.5x (TERMINAL.EXE), Windows NT 4.0 (HyperTerminal), and Linux UNIX freeware (minicom).

Xmodem and Ymodem downloads are slow. Use them only when the switch does not have network access. You can speed up the transfer by setting the console port speed to 38400 bps.

Xmodem and Ymodem file transfers are performed from the ROM monitor with the following command:
xmodem [-y] [-c] [-s data-rate]
In the example, the -y option uses the Ymodem protocol, -c provides CRC-16 checksumming, and -s sets the console port data rate.

Note See the "ROM Monitor Command-Line Interface" section in the "Command-Line Interfaces" chapter for more information about the ROM monitor.

The computer from which you transfer the supervisor engine software image must run terminal emulation software that supports the Xmodem or Ymodem protocol.

The following procedure shows a file transfer using the Xmodem protocol. To use the Ymodem protocol, include the -y option with the xmodem command.

Caution A modem connection from the telephone network to your console port introduces security issues that you should consider before enabling the connection. For example, remote users can dial into your modem and access the switch configuration settings.

Caution If you have redundant supervisor engines, you must remove the second (redundant) supervisor engine before you perform this procedure. The image that is downloaded through Xmodem is not saved to memory; therefore, after the download if you have two supervisor engines installed and attempt to reboot the active supervisor engine with the downloaded image, the redundant supervisor engine will take over and synchronize with the active supervisor engine. The downloaded image will not be booted.

Step 1 Place a supervisor engine software image on the computer's hard drive. You can download an image from Cisco.com (see the "Preface" section for details).

Step 2 To download from a local computer, connect the console port (port mode switch in the in position) to a serial port on the computer using a null-modem cable. The console port speed must match the speed that is configured on the local computer.

Note If you are transferring from a local computer, you may need to configure the terminal emulation program to ignore RTS/DTR signals.

Step 3 To download from a remote computer, do the following:

a. Connect a modem to the console port and to the telephone network.

b. Note that the modem and console port must communicate at the same speed, which can be from 1200 to 38400 bps, depending on the speed that is supported by your modem. Enter the confreg ROM monitor command to configure the console port transmission speed.

c. Connect a modem to the remote computer and to the telephone network and configure it for the same speed as the supervisor engine.

d. Dial the number of the supervisor engine modem from the remote computer.

Step 4 Enter the xmodem command at the ROM-monitor prompt in the terminal emulation window:
rommon > xmodem -s 38400 -c
Step 5 Start an Xmodem or Ymodem send operation with the computer's terminal emulation software. The computer downloads the system image to the supervisor engine. See your terminal emulation software application manual for instructions on how to execute a Xmodem or Ymodem file transfer.

After the new image is completely downloaded, the ROM monitor boots it.

Note Downloading an image through the console port does not create an image file on any of the Flash devices. The downloaded image resides only in memory. You cannot save the image in memory as a file.

Step 6 After the download, the console port returns to 9600, which is the default baud rate. If the download took place at other than 9600 baud, you must change the remote computer's baud rate back to 9600 baud.

Step 7 Establish network connectivity to the switch to copy an image file from a TFTP server to one of the Flash devices.
