Addresses And Port Numbers; Hardware Address; Ip Address; Port Numbers - Lantronix EDS2100 User Manual

Command Mode: There are two methods for accessing Command Mode (CLI): making a Telnet
connection or connecting a terminal (or a PC running a terminal emulation program) to the unit's
serial port. (See the EDS1100/2100 Device Server Command Reference for instructions and
available commands. Lantronix documentation is available at
www.lantronix.com/support/documentation.)
XML: The EDS1100/2100 supports XML-based configuration and setup records that make device
configuration transparent to users and administrators. XML is easily editable with a standard text
or XML editor. (See the EDS1100/2100 Device Server Command Reference for instructions and
available commands. Lantronix documentation is available at
www.lantronix.com/support/documentation.)

Addresses and Port Numbers

Hardware Address

The hardware address is also referred to as the Ethernet address or MAC address. The first three
bytes of the Ethernet address are fixed and read as either 00-20-4A or 08-04-13, identifying the
unit as a Lantronix product. The fourth, fifth, and sixth bytes are unique numbers assigned to each
unit.

IP Address

Every device connected to an IP network must have a unique IP address. This address references
the specific unit.

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
port number 23.
The following is a list of the default server port numbers running on the EDS1100/2100.
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 443: HTTPS (Web Manager configuration)

UDP Port 161: SNMP

TCP Port 21: FTP

UDP Port 69: TFTP

UDP Port 30718: LDP (Lantronix Discovery Protocol) port

TCP/UDP Port 10001: Tunnel 1
