EDS User Guide 23
Web Manager: Through a web browser, configure the EDS settings using the Lantronix Web
Manager. See Configuration Using Web Manager (on page 43).
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 EDS Command Reference Guide for instructions and available commands.)
XML: The EDS 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 EDS Command Reference Guide for instructions and commands.)
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 00-20-4A, identifying the unit as a Lantronix
product. The fourth, fifth, and sixth bytes are unique numbers assigned to each unit.
Figure 2-4 Sample Hardware Address
00-20-4A-14-01-18 or 00:20:4A:14:01:18
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 EDS:
 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 514: Syslog
 TCP Port 515: LPD
 UDP Port 30718: LDP (Lantronix Discovery Protocol) port
 TCP/UDP Port 10001: Tunnel 1
