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 file and enter the port number specified 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 files used in secure copy transfer.
• ip ssh authentication-retries : configure the maximum number of attempts that should be used to authenticate a
user.
• ip ssh connection-rate-limit : configure the maximum number of incoming SSH connections per minute.
