LAN Ports Used By the Integrated Controller
LAN Port Descriptions
Port type Description
Standard Port #
FTP
The on-board Master has a built-in FTP server.
21/20 (TCP)
SSH
The SSH port functions using the same interface as Telnet but over a
secure shell where it uses SSL as a mechanism to configure and diagnose
a NetLinx system.
This port value is used for secure Telnet communication.
Note: SSH version 2 is only supported.
22 (TCP)
Telnet
The NetLinx Telnet server provides a mechanism to configure and
diagnose a NetLinx system.
For maximum flexibility, the Master can be configured to utilize a different
port than 23, or disable Telnet completely from either Telnet or the
Program Port located on the rear of the Master itself. Once disabled, the
only way to enable Telnet again is from the Master’s Program port.
23 (TCP)
HTTP
The Master has a built-in web server that complies with the HTTP 1.0
specification and supports all of the required features of HTTP v1.1.
This port is used for unsecure HTTP Internet communication between the
web browser’s UI and the target Master.
80 (TCP)
HTTPS/SSL
This port is used by a web browser to securely communicate between the
web server UI and the target Master. This port is also used to
simultaneously encrypt this data using the SSL certificate information on
the Master as a key.
443 (TCP)
ICSP
Peer-to-peer protocol used for both Master-to-Master and Master-to-
device communications.
For maximum flexibility, the Master can be configured to utilize a different
port than 1319, or disable ICSP over LAN completely from either Telnet or
the Program Port located on the rear of the Master itself.
This type of communication is used by the various AMX product for
communication amongst themselves.
1319 (UDP/TCP)
integration!
Solutions
This feature on the Master uses, by default, port 10500 for the XML based
communication protocol. This port is connected to by the client web
browser’s JVM when integration! Solutions control pages are retrieved
from the on-board Master’s web server.
For maximum flexibility, the on-board Master can be configured to utilize a
different port than 10500 or to disable integration! Solutions completely.
10500 (TCP)
