Switch memory allows up to ten public keys. This means the authentication and encryption keys you use for your third-party client SCP/SFTP software can differ from the keys you use for the SSH session, even though both SCP and SFTP use a secure SSH tunnel.


SSH authentication is mutually exclusive with RADIUS servers.

Some clients, such as PSCP (PuTTY SCP), automatically compare switch host keys for you. Other clients require you to manually copy and paste keys to the $HOME/.ssh/known_hosts file. Whatever SCP/SFTP software tool you use, after installing the client software you must verify that the switch host keys are available to the client.

Because the third-party software utilities you may use for SCP/SFTP vary, you should refer to the documentation provided with the utility you select before performing this process.
