2) Logon Cisco MDS switch as "root" or "admin", run
NJRDC9506# config t
Enter configuration commands, one per line. End with CNTL/Z.
NJRDC9506(config)# username admin sshkeyssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC7GKY9+Qrfq+NXYgMr4Nf8z/EeE5qxe4ewiZNlf8wep9smPBTXPeAFUJ5OpjNnmv3kRhVe7Gto9YB5iG19UTXoW6lCeDBlAirQYvA1zQz1yi/vxD0osKY+zXRc2o3WAQKrvIC6usjzDigvimaQfxv/nXkWGlP3RapKmS/3R5Zi8f2gWqWMQcNJUk9U/uEd5724NjTeIxDOZrshWFjhbAIWZPGQk8dGZEURlx0UsvMZR/1Eab6eXMTuFE0J6dJnBi+ioanrYtguQLqxEpv7HKt44eXYa1B+uu0cyU/yiYjOmdrTs7NcJPZuBARmlIQFtasbJM+8xakNx7BWMd7qqYbB chenk6@CNRDCHENK6L1C
NJRDC9506(config)# end

3) Check the public key
NJRDC9506# show user-account admin
user:admin
this user account has no expiry date
roles:network-admin
ssh public key: ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC7GKY9+Qrfq+NXYgMr4Nf8z/EeE5qxe4ewiZNlf8wep9smPBTXPeAFUJ5O

4) Test the setup, issuing MDS CLI from host by ssh should have no password prompt.
