Figure 42-6. Specifying an SSH version FTOS(conf)#ip ssh server version 2 FTOS(conf)#do show ip ssh SSH server : disabled. SSH server version : v2. Password Authentication : enabled. Hostbased Authentication : disabled. RSA Authentication : disabled. To disable SSH server functions, enter no ip ssh server enable. 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 procedure: Step Task Command Syntax 1 On Chassis One, set the SSH port number (port 22 by default). ip ssh server port number 2 On Chassis One, enable SSH. ip ssh server enable 3 On Chassis Two, invoke SCP. copy scp: flash: 4 On Chassis Two, in response to prompts, enter the path to the desired file and enter the port number specified in Step 1. Command Mode CONFIGURATION CONFIGURATION CONFIGURATION EXEC Privilege This 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: Figure 42-7. Using SCP to copy from an SSH Server on another Switch FTOS#copy scp: flash: Address or name of remote host []: 10.10.10.1 Port number of the server [22]: 99 Source file name []: test.cfg User name to login remote host: admin Password to login remote host: 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.
