2: Introduction
Port Numbers
Every TCP connection and every UDP datagram is defined by a destination and source IP address, and a destination and source port number. For example, a Telnet server commonly uses TCP port number 23.
The following is a list of the default server port numbers running on the
TCP Port 22: SSH Server (Command Mode configuration)
TCP Port 23: Telnet Server (Command Mode configuration)
TCP Port 80: HTTP (Web Manager configuration)
TCP Port 21: FTP
UDP Port 30718: LDP (Lantronix Discovery Protocol) port
TCP/UDP Port 10001: Tunnel 1
Note: Additional TCP/UDP ports and tunnels will be available, depending on the product type. The default numbering of each additional TCP/UDP port and corresponding tunnel will increase sequentially (i.e., TCP/UDP Port 1000X: Tunnel X).
