Information About SSH and Telnet

SSH Server

The Secure Shell Protocol (SSH) server feature enables a SSH client to make a secure, encrypted connection
to a Cisco Nexus 5000 Series switch. SSH uses strong encryption for authentication. The SSH server in the
Cisco Nexus 5000 Series switch will interoperate with publicly and commercially available SSH clients.
The user authentication mechanisms supported for SSH are RADIUS, TACACS+, and the use of locally
stored user names and passwords.

SSH Client

The SSH client feature is an application running over the SSH protocol to provide device authentication and
encryption. The SSH client enables a Cisco Nexus 5000 Series switch to make a secure, encrypted connection
to another Cisco Nexus 5000 Series switch or to any other device running an SSH server. This connection
provides an outbound connection that is encrypted. With authentication and encryption, the SSH client allows
for a secure communication over an insecure network.
The SSH client in the Cisco Nexus 5000 Series switch works with publicly and commercially available SSH
servers.

SSH Server Keys

SSH requires server keys for secure communications to the Cisco Nexus 5000 Series switch. You can use
SSH keys for the following SSH options:
• SSH version 2 using Rivest, Shamir, and Adelman (RSA) public-key cryptography
• SSH version 2 using the Digital System Algrorithm (DSA)
