Similarly, ifthe protocol inbound ssh command has been executed, the authentication-mode passwordand authentication-mode none commands are not available.Configuring the SSH Management FunctionsThe SSH server provides a number of management functions to prevent illegal operations such asmalicious password guess, guaranteeing the security of SSH connections. You can specify the IPaddress or the interface corresponding to the IP address for the SSH server to provide SSH accessservices for clients. In this way, the SSH client accesses the SSH server only using the specified IPaddress. This increases the service manageability when the SSH server has multiple interfaces and IPaddresses.Follow these steps to configure SSH management functions:To do... Use the command...
