How It Works; The Scp/Sftp Process - HP PROCURVE 2520 Management And Configuration Manual

File Transfers
Downloading Switch Software
SCP (secure copy) is an implementation of the BSD rcp (Berkeley UNIX
remote copy) command tunneled through an SSH connection.
SCP is used to copy files to and from the switch when security is required.
SCP works with both SSH v1 and SSH v2. Be aware that the most third-party
software application clients that support SCP use SSHv1.

How It Works

The general process for using SCP and SFTP involves three steps:
1. Open an SSH tunnel between your computer and the switch if you haven't
2. Execute ip ssh filetransfer to tell the switch that you want to enable secure
3. Use a third-party client application for SCP and SFTP commands.

The SCP/SFTP Process

To use SCP and SFTP:
1. Open an SSH session as you normally would to establish a secure
2. To enable secure file transfer on the switch (once you have an SSH session

switches or connections. If you have already done it once you should not
need to do it a second time.
