Working with Software Images
• When you upload an image to the RCP to the server, it must be properly configured to accept the
RCP write request from the user on the switch. For UNIX systems, you must add an entry to the
.rhosts file for the remote user on the RCP server. For example, suppose the switch contains these
configuration lines:
hostname Switch1
ip rcmd remote-username User0
If the switch IP address translates to Switch1.company.com, the .rhosts file for User0 on the RCP
server should contain this line:
Switch1.company.com Switch1
For more information, refer to the documentation for your RCP server.
Downloading an Image File By Using RCP

Beginning in privileged EXEC mode, follow Steps 1 through 6 to download a new image from an RCP
server and overwrite the existing image. To keep the current image, skip Step 6.
