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 ip 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 Example of Using SCP to Copy from an SSH Server on Another Switch Other SSH-related commands 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.
