File Transfers

Downloading Switch Software

Note

SFTP over SSH version 1 (SSH v1) is not supported. A request from either the

 

client or the switch (or both) using SSH v1 generates an error message. The

 

actual text of the error message differs, depending on the client software in

 

use. Some examples are:

 

Protocol major versions differ: 2 vs. 1

 

Connection closed

 

Protocol major versions differ: 1 vs. 2

 

Connection closed

 

Received disconnect from < ip-addr>: /usr/local/

 

libexec/sftp-server: command not supported

 

Connection closed

 

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 already done so. (This step assumes that you have already set up SSH on the switch.)

2. Execute ip ssh filetransfer to tell the switch that you want to enable secure file transfer.

3. Use a third-party client application for SCP and SFTP commands.
