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.

When you download a 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.

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

•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 (for example, /tftpboot on a UNIX workstation).

•Ensure that the permissions on the file are set correctly. Permissions on the file should be at least read for the specific username. If you are not using a Telnet session with a valid username, you can use the set rcp username command to specify a valid 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. 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 Engine Images Using TFTP

To download a supervisor engine software image to the switch from a TFTP server, follow 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 Download the software image from the TFTP server using 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.

Note The Catalyst 4000 family, 2948G, and 2980G switches have only one Flash device (bootflash:).

The switch downloads the image file from the TFTP server, and the image is copied to the bootflash.

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.

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.

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 "Using 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.

•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. On a UNIX workstation, create an empty file by entering 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

To upload a software image on a switch to a TFTP server for storage, follow 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 using 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 to a TFTP server:

Downloading System Software Images to the Switch Using rcp

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

•Understanding How rcp Software Image Downloads Work

•Preparing to Download an Image Using rcp

•Downloading Supervisor Engine Images Using rcp

•Example rcp Download Procedures

Understanding How rcp Software Image Downloads Work

You can download system software images to the switch using the remote copy protocol (rcp); rcp allows you to download system image files over the network from an rcp server.

You can store multiple image files in the Flash memory.

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

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. 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.

Downloading Supervisor Engine Images Using rcp

To download a supervisor engine software image to the switch from an rcp server, follow 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 using 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.

Note The Catalyst 4000 family, 2948G, and 2980G switches have only one Flash device (bootflash:).

The switch downloads the image file from the rcp server, and copies the image to bootflash.

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.
