How to Configure X.509v3 Certificates for SSH Authentication
Configuring Digital Certificates for User Authentication
Step 6
Switch(ssh-server-cert-profile-server)#
trustpoint sign
PKI-trustpoint-name
Attaches the public key infrastructure (PKI) trustpoint to the server
certificate profile.
•
The SSH server uses the certificate associated with this PKI
trustpoint for server authentication.
Step 7
Switch(ssh-server-cert-profile-server)#
ocsp-response include
(Optional) Sends the Online Certificate Status Protocol (OCSP)
response or OCSP stapling along with the server certificate.
Note
By default, no OCSP response is sent along
with the server certificate.
Step 8
Switch(ssh-server-cert-profile-server)#
end
Exits SSH server certificate profile server configuration mode and
returns to privileged EXEC mode.
Command or Action
Purpose
Step 1
Switch>
enable
Enables privileged EXEC mode.
•
Enter your password if prompted.
Step 2
Switch#
configure terminal
Enters global configuration mode.
Step 3
Switch(config)#
ip ssh server algorithm
authentication
{
publickey
|
keyboard
|
password
}
Defines the order of host key algorithms. Only the configured
algorithm is negotiated with the Secure Shell (SSH) client.
Note
The IOS SSH server must have at least one
configured host key algorithm.
•
To use the certificate method for user authentication, the
publickey
keyword must be configured.
Step 4
Switch(config)#
ip ssh server algorithm
publickey
{
x509v3-ssh-rsa
[
ssh-rsa
] |
ssh-rsa
[
x509v3-ssh-rsa
]}
Defines the order of public key algorithms. Only the configured
algorithm is accepted by the SSH client for user authentication.
Note
The IOS SSH client must have at least one
configured public key algorithm.
•
x509v3-ssh-rsa
—Certificate-based authentication
•
ssh-rsa
—Public-key-based authentication
Step 5
Switch(config)#
ip ssh server
certificate profile
Configures server certificate profile and user certificate profile and
enters SSH certificate profile configuration mode.
Step 6
Switch(ssh-server-cert-profile)#
user
Configures user certificate profile and enters SSH server certificate
profile user configuration mode.
