Using SCP with SSH to Copy a Software Image
To use secure copy (SCP) to copy a software image through an SSH connection from one switch to another, use the following
commands.
1. On Switch 1, set the SSH port number ( port 22 by default).
CONFIGURATION MODE
ip ssh server port number
2. On Switch 1, enable SSH.
CONFIGURATION MODE
copy ssh server enable
3. On Switch 2, invoke SCP.
CONFIGURATION MODE
copy scp: flash:
4. On Switch 2, in response to prompts, enter the path to the desired le and enter the port number specied in Step 1.
EXEC Privilege Mode
5. On the chassis, invoke SCP.
CONFIGURATION mode
copy scp: flash:
Example of Using SCP to Copy from an SSH Server on Another Switch
The following example shows the use of SCP and SSH to copy a software image from one switch running SSH server on UDP port
99 to the local switch.
Other SSH related command include:
• crypto key generate : generate keys for the SSH server.
• debug ip ssh : enables collecting SSH debug information.
• ip scp topdir : identify a location for les used in secure copy transfer.
• ip ssh authentication-retries : congure the maximum number of attempts that should be used to authenticate a
user.
• ip ssh connection-rate-limit : congure the maximum number of incoming SSH connections per minute.
• ip ssh hostbased-authentication enable : enable host-based authentication for the SSHv2 server.
• ip ssh key-size : congure the size of the server-generated RSA SSHv1 key.
• ip ssh password-authentication enable : enable password authentication for the SSH server.
• ip ssh pub-key-file : specify the le the host-based authentication uses.
• ip ssh rhostsfile : specify the rhost le the host-based authorization uses.
• ip ssh rsa-authentication enable : enable RSA authentication for the SSHv2 server.
• ip ssh rsa-authentication : add keys for the RSA authentication.
