SSH Terminal Services 205
SSH Client Configuration Table 186 describes SSH configuration tasks.
In the initial authentication, if the SSH client does not have the public key for the
server which it accesses for the first time, the client continues to access the server and
save locally the public key of the server. Then at the next access, the client can
authenticate the server using the public key saved locally.
Displaying SSH
Configuration
Use the display commands in any view to view the running of SSH and further to
check the configuration result.
Users using SecureCRT as the client side software will fail to log onto a switch if they
check the Enable OpenSSH agent forwarding option.
