The results of the display rsa local-key-pair public command or the public key converted with the
SSHKEY tool contains no information such as the authentication type, so they cannot be directly used
as parameters in the public-key peer command. For the same reason, neither can the results of the
display public-key local rsa public command be used in the rsa peer-public-key command directly.
SSH Configuration Examples
When Switch Acts as Server for Local Password Authentication
Network requirements
As shown in Figure 1-11, establish an SSH connection between the host (SSH Client) and the switch

authentication is required.
