  Chapter 6: Configuring Switch Access

BMD00082, February 2009

Secure Shell (SSH) and Secure Copy (SCP) use secure tunnels to encrypt and secure messages 
between a remote administrator and the switch. Telnet does not provide this level of security. 
The Telnet method of managing a switch does not provide a secure connection.

SSH is a protocol that enables remote administrators to log securely into the switch over a net-
work to execute management commands. 

SCP is typically used to copy files securely from one machine to another. SCP uses SSH for 
encryption of data on the network. SCP is used to download and upload the switch configura-
tion via secure channels.

The benefits of using SSH and SCP are listed below:

„

Authentication of remote administrators

„

Identifying the administrator using Name/Password

„

Authorization of remote administrators

„

Determining the permitted actions and customizing service for individual administrators

„

Encryption of management messages 

„

Encrypting messages between the remote administrator and the switch 

„

Secure copy support

The switch supports SSH versions 1.5 and 2.0. and supports SSH clients version 1.5 - 2.x. 
The following SSH clients have been tested: 

„

SSH 1.2.23 and SSH 1.2.27 for Linux (freeware)

„

SecureCRT 3.0.2 and SecureCRT 3.0.3 for Windows NT (Van Dyke Technologies, Inc.)

„

F-Secure SSH 1.1 for Windows (Data Fellows)

„

Putty SSH
