SSH Servers, Integrated Clients, and Supported Versions
The SSH feature has an SSH server and an SSH integrated client, which are applications that run on the switch.
You can use an SSH client to connect to a switch running the SSH server. The SSH server works with the
SSH client supported in this release and with non-Cisco SSH clients. The SSH client also works with the SSH
server supported in this release and with non-Cisco SSH servers.
The switch supports an SSHv1 or an SSHv2 server.
The switch supports an SSHv1 client.
SSH supports the Data Encryption Standard (DES) encryption algorithm, the Triple DES (3DES) encryption
algorithm, and password-based user authentication.
SSH also supports these user authentication methods:
• TACACS+
• RADIUS
• Local authentication and authorization
