Downloading System Software Images to the Switch Using rcp

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.
For more information on working with system software image files on the Flash file system, see
Chapter 34, "Working With 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:

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

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 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 is stored in NVRAM. If you are accessing the switch through a Telnet session with a valid
username, this username is used and you do not 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.
The Catalyst 4500 series, 2948G, 2948G-GE-TX, and 2980G switches have only one Flash
device (bootflash).
The switch remains operational while the image downloads.
