ServSwitch™ DKM
138
Appendix D: Network Interface
The network interface offers the following ports and protocols:
FTP Server (Port 21):
Port 21 provides access to an FTP-Server, e.g. for the upload and download of configuration
files (cf. p. 75 „Configuration via FTP“). For login, user account information of the current
configuration has to be applied. Access to the FTP Server is granted according to the user
rights defined there.
Telnet Server (Port 23)
Port 23 has been reserved for a future Telnet Server. For login, current user access rights will
be applied, as described for Port 21.
HTTP Server (Port 80)
Port 80 provides access to an HTTP Server. For access to restricted areas, current user access
rights will be applied, as described for Port 21. Currently, the HTTP Server provides no pages
yet. In a future version, however, pages for configuration, control and status monitoring will
be available. Necessary files can be loaded or updated via FTP server. Thus, users may store
own Java applications there that could access the device via FTP server or socket server and
control the switch or change configuration.
Socket Server (Port 5555)
Port 5555 provides access to a Socket Server supporting the same protocol like the serial
interface. Access to this port is NOT restricted by user rights. Functionality and protocol
correspond to the serial interface described in Appendix C: Serial Interface (p. 133). The
switching functionality corresponds to the Switching in OSD / Crosspoint Mode (p. 104).
Optionally, the ServSwitch™ DKM echoes all executed switch commands via either the
serial interface or the network
interface. By means of this echo, the actual switch status of the switch can be monitored at
any time and user applications can be realized based on this echo.
