STelnet is based on SSH2.0. The client and server set up a secure connection through negotiation. STelnet enables the client to log in to the server.
As shown in Figure 1:
Support for both STelnet client and server functions
A device can function as either an STelnet server or a client that accesses other STelnet servers.
Enabling or disabling of the STelnet server function
