Software Image Naming Conventions

The software images on the Catalyst 6500 series switches use the following naming conventions (software release 7.3(1) images for a Supervisor Engine 2 are 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 the EPLD Images

---

Note The supervisor engine EPLD upgrades are supported only on Supervisor Engine 2 and Supervisor Engine 720. The nonsupervisor engine module (switching modules and service modules) EPLD upgrades are supported using Supervisor Engine 1, Supervisor Engine 2, or Supervisor Engine 720.

---

The EPLD image for Supervisor Engine 2 and Supervisor Engine 720 is included in the Catalyst supervisor engine software image. The EPLD image for the 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 you reset or power cycle the switch. 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 keyword for the 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 keyword for the 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 the 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 the Nonsupervisor Engine Module EPLD Images

---

Caution Do not power off or reset the switch or module during the upgrade process. Powering off or resetting the switch or module 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 the Software Images Using FTP or TFTP

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

•Understanding How FTP and TFTP Software Image Downloads Work

•Specifying the FTP Username and Password

•Preparing to Download an Image Using FTP or TFTP

•Downloading the Supervisor Engine Images Using FTP or TFTP

•Downloading the Switching Module Images Using FTP or TFTP

•FTP and TFTP Download Procedures Example

Understanding How FTP and TFTP Software Image Downloads Work

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

Some modules, such as the 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 that 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 (if 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 that is 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 the system software image files on the flash file system, see Chapter 26, "Working With the Flash File System."

---

Specifying the FTP Username and Password

FTP allows you to specify a username and password to be used for the FTP connection.

To specify the username and password, perform these steps:

---

Step 1 Enter the set ftp username new_ftp_username command.

Step 2 Enter the set ftp password command.

---

This example shows how to set the FTP username:

Console> (enable) set ftp username doc_people

ftp username set to doc_people

This example shows how to set the FTP password:

Console> (enable) set ftp password 

Enter password for User 'doc_people':

Retype password for User 'doc_people':

ftp password set.

This example shows how to clear the FTP username:

Console> (enable) clear ftp username

This example shows how to clear the FTP password:

Console> (enable) clear ftp password

You can also connect to an FTP server using passive mode. In passive mode, the client initiates the connection to the server. To use passive mode, enter the set ftp passive command.

Preparing to Download an Image Using FTP or TFTP

Before you begin downloading a software image using FTP or TFTP, do the following:

•Verify that the workstation acting as the TFTP server is configured properly. When using TFTP on a Sun workstation, verify that the /etc/inetd.conf file contains this line:

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

Verify that the /etc/services file contains this line:

tftp 69/udp

When using FTP on a Sun workstation, verify that the /etc/inetd.conf file contains this line:

ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd 

Verify that the /etc/services file contains this line:

ftp 21/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 FTP or TFTP daemon.

---

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

•Verify that the software image to be downloaded is in the correct directory on the FTP or TFTP server.

•Verify that the permissions on the file are set correctly. The permissions on the file should be set to world-read.

•Note that 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 the Supervisor Engine Images Using FTP or TFTP

---

Note If you have a redundant supervisor engine, you cannot download a system image directly from an FTP or 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 an FTP or TFTP server, perform these steps:

---

Step 1 Copy the software image file to the appropriate FTP or 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 ftp flash or 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 FTP or 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 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.

---

---

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

---

Downloading the Switching Module Images Using FTP or TFTP

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

---

Step 1 Copy the software image file to the appropriate FTP or 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 the modules to run the new software.

Step 3 If there is only one module of the type that is 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 ftp flash or copy tftp flash command. When prompted, enter the IP address or the 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 that is appropriate for the image but you only want to update a single module, enter the copy ftp m/bootflash: or 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 by entering 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 the complete procedures on FTP and TFTP downloads to the intelligent modules, see the "Single Module Image Download Example" section and the "Multiple Module Image Download Example" section.

Uploading the System Software Images to an FTP or TFTP Server

These sections describe how to upload the system software images from a switch to an FTP or TFTP server:

•Preparing to Upload an Image to an FTP or TFTP Server

•Uploading the Software Images to an FTP or TFTP Server

---

Note For more information on working with the system software image files on the flash file system, see Chapter 26, "Working With the Flash File System."

---

Preparing to Upload an Image to an FTP or TFTP Server

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

•Verify that the workstation acting as the FTP or TFTP server is configured properly. When using FTP on a Sun workstation, make sure that the /etc/inetd.conf file contains this line:

ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd

Verify that the /etc/services file contains this line:

ftp 21/udp

When using TFTP on a Sun workstation, verify that the /etc/inetd.conf file contains this line:

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

Verify 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.

---

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

•Note that you might need to create an empty file on the FTP or 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), verify that the permissions on the file are set correctly. The permissions on the file should be world-write.

Uploading the Software Images to an FTP or TFTP Server

To upload a software image on a switch to an FTP or 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 FTP or TFTP server with the copy flash ftp or copy flash tftp command. When prompted, specify the FTP or TFTP server address and destination filename. On those platforms that support the flash file systems, you are first prompted for the flash device and the source filename. If desired, you can enter the copy file-id ftp or copy file-id tftp command on these platforms.

The software image is uploaded to the FTP or TFTP server.

---

Downloading the System Software Images Using rcp

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

•Preparing to Download an Image Using rcp

•Downloading the Supervisor Engine Images Using rcp

•Downloading the 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, do the following:

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

•Verify 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 the traffic between the subnets. Check the connectivity to the rcp server by entering 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 that 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 by entering 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 the 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 the 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 the modules to run the new software.

Step 3 Enter the command that is 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 that is 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 that is 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 the 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 the 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
