Lantronix EDS8PS, EDS32PR, EDS16PR, EDS8PR Addresses and Port Numbers, Hardware Address, IP Address

2: Introduction

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
