Steps for Configuring and Using SSH
for Switch and Client Authentication
For two-way authentication between the switch and an SSH client, you must
use the login (Operator) level.

For ssh login public-key, the switch uses client public-key authentication instead of the switch password options for
primary authentication.
The general steps for configuring SSH include:
A. Client Preparation
1. Install an SSH client application on a management station you want
to use for access to the switch. (Refer to the documentation provided
with your SSH client application.)
2. Optional—If you want the switch to authenticate a client public-key
on the client:
a.Either generate a public/private key pair on the client computer (if
your client application allows) or import a client key pair that you
have generated using another SSH application.
b.Copy the client public key into an ASCII file on a TFTP server
accessible to the switch and download the client public key file to
the switch. (The client public key file can hold up to 10 client keys.)

File” on page 7-25.
