Overview

The switches covered in this guide use Secure Shell version 2 (SSHv2) to
provide remote access to management functions on the switches via
encrypted paths between the switch and management station clients capable
of SSH operation.
SSH provides Telnet-like functions but, unlike Telnet, SSH provides
encrypted, authenticated transactions. The authentication types include:
■ Client public-key authentication
Switch SSH and user password authentication
■
Client Public Key Authentication (Login/Operator Level) with User
Password Authentication (Enable/Manager Level). This option uses
one or more public keys (from clients) that must be stored on the switch. Only
a client with a private key that matches a stored public key can gain access
to the switch. (The same private key can be stored on one or more clients.)
1. Switch-to-Client SSH authentication.
2. Client-to-Switch (login rsa) authentication
3.User-to-Switch (enable password) authentication
options:
– Local
– TACACS+
– RADIUS
– None
