You can configure a source IP address for the SSH server to provide SSH access service for the SSH
clients. In this way, the SSH clients can only access the SSH server using the specified IP address as
the destination. This improves the service manageability when the SSH server has multiple IP
addresses.
Examples
# Specify source IP address 192.168.0.1 for the SSH server.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] ssh-server source-ip 192.168.0.1
