Appendix B Working with the Cisco IOS File System, Configuration Files, and Software Images Working with Software Images Before you begin downloading or uploading an image file by using RCP, do these tasks: • 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 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 using the ping command. • If you are accessing the switch through the console or a Telnet session and you do not have 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 privileged EXEC command to view the valid username. If you do not want to use this username, create a new RCP username by using the ip rcmd remote-username username global configuration command to be used during all archive operations. The new username is stored in NVRAM. If you are accessing the switch through a Telnet session and you have a valid username, this username is used, and there is no need to set the RCP username. Include the username in the archive download-sw or archive upload-sw privileged EXEC command if you want to specify a username only for that operation. • 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 You can download a new image file and replace or keep the current image. 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. Command Step 1 Step 2 Step 3 configure terminal Step 4 ip rcmd remote-username username Step 5 end Purpose Verify that the RCP server is properly configured by referring to the "Preparing to Download or Upload an Image File By Using RCP" section on page B-28. Log into the switch through the console port or a Telnet session. Enter global configuration mode. This step is required only if you override the default remote username (see Steps 4 and 5). (Optional) Specify the remote username. Return to privileged EXEC mode. 78-11380-10 Catalyst 2950 and Catalyst 2955 Switch Software Configuration Guide B-29
