Note:
To improve security and prevent attacks to the unused Sockets, TCP 23 and TCP 22,
ports for Telnet and SSH services respectively, will be enabled or disabled after
corresponding configurations.
If the authentication mode is none, TCP 23 will be enabled, and TCP 22 will be
disabled.
If the authentication mode is password, and the corresponding password has been
set, TCP 23 will be enabled, and TCP 22 will be disabled.
If the authentication mode is scheme, there are three scenarios: when the
supported protocol is specified as telnet, TCP 23 will be enabled; when the
supported protocol is specified as ssh, TCP 22 will be enabled; when the supported
protocol is specified as all, both the TCP 23 and TCP 22 port will be enabled.
