2: Introduction 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 EDS3000 Device Server Command Reference for instructions and available commands. Lantronix documentation is available at www.lantronix.com/support/documentation.) XML: The EDS3000 devices 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 EDS3000 Device Server Command Reference for instructions and available commands. Lantronix documentation is available at www.lantronix.com/support/documentation.) Web API: The Web APIs are restful APIs that allow access to a subset of device server functions through a standard HTTP request. They can be used to export and import configuration, export status, take a status action, and manipulate the file system. See the EEDS3000 Device Server Command Reference for details and a list of actions. Addresses and Port Numbers Hardware Address The hardware address is also referred to as the Ethernet address or MAC address.

EDS3000 Device Server User Guide

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
EDS3000 Device Server Command Reference
for instructions and available
commands. Lantronix documentation is available at
www.lantronix.com/support/documentation
.)
XML:
The EDS3000 devices 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
EDS3000 Device Server Command Reference
for
instructions and available commands. Lantronix documentation is available at
www.lantronix.com/support/documentation
.)
Web API:
The Web APIs are restful APIs that allow access to a subset of device server functions
through a standard HTTP request. They can be used to export and import configuration, export
status, take a status action, and manipulate the file system. See the E
EDS3000 Device Server
Command Reference
for details and a list of actions.
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 08-04-13, identifying the unit as a Lantronix
product. The fourth, fifth, and sixth bytes are unique numbers assigned to each unit.
Figure 2-6
Sample Hardware Address
08-04-13-14-01-18
or
08:04:13:14:01:18
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 EDS3000 device server.
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
