2: Introduction Configuration Methods For the unit to operate correctly on a network, it must have a unique IP address on the network. There are three basic methods for logging into the device server: DeviceInstaller: View the current MatchPort configuration using a Graphical User Interface (GUI) on a PC attached to a network. (See 3: Using DeviceInstaller.) Web-Manager: Through a Web interface, configure the MatchPort and its settings. (See 4: Configuration Using Web-Manager.) Serial & Telnet Ports: There are two approaches to accessing Serial Mode. Make a Telnet connection to the network port (9999) or connect a terminal (or a PC running a terminal emulation program) to serial port 1. (See 5: Configuration via Serial Mode or Telnet Port.) Addresses and Port Numbers Hardware Address The hardware address is also referred to as the Ethernet address or the 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. Example: 00-20-4A-14-01-18 Note: Make note of the MAC address. It is needed to locate the MatchPort using DeviceInstaller. IP Address Every device connected to an IP network must have a unique IP address used to reference the specific unit. The MatchPort is automatically assigned an IP address on DHCP-enabled networks, as it is DHCP-enabled by default. Port Numbers Every TCP connection and every UDP datagram is defined by a destination IP address and a port number. For example, a Telnet application commonly uses port number 23. A port number is similar to an extension on a phone system. The unit's serial channel (port) can be associated with a specific TCP/UDP port number. Port number 9999 is reserved for access to the unit's Setup (configuration) Mode window. Ports 0-1024 are reserved as well. For more information on reserved port numbers, refer to Table 5-6. Reserved Port Numbers. MatchPort User Guide 14

2: Introduction
Configuration Methods
For the unit to operate correctly on a network, it must have a unique IP address on
the network. There are three basic methods for logging into the device server:
DeviceInstaller
: View the current MatchPort configuration using a Graphical User
Interface (GUI) on a PC attached to a network. (See
3: Using DeviceInstaller
.)
Web-Manager
: Through a Web interface, configure the MatchPort and its settings.
(See
4: Configuration Using Web-Manager
.)
Serial & Telnet Ports
: There are two approaches to accessing Serial Mode. Make a
Telnet connection to the network port (9999) or connect a terminal (or a PC running a
terminal emulation program) to serial port 1. (See
5: Configuration via Serial Mode or
Telnet Port
.)
Addresses and Port Numbers
Hardware Address
The hardware address is also referred to as the Ethernet address or the 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.
Example:
00-20-4A-14-01-18
Note:
Make note of the MAC address. It is needed to locate the MatchPort
using DeviceInstaller.
IP Address
Every device connected to an IP network must have a unique IP address used to
reference the specific unit. The MatchPort is automatically assigned an IP address on
DHCP-enabled networks, as it is DHCP-enabled by default.
Port Numbers
Every TCP connection and every UDP datagram is defined by a destination IP
address and a port number. For example, a Telnet application commonly uses port
number 23. A port number is similar to an extension on a phone system.
The unit's serial channel (port) can be associated with a specific TCP/UDP port
number. Port number 9999 is reserved for access to the unit's Setup (configuration)
Mode window. Ports 0-1024 are reserved as well. For more information on reserved
port numbers, refer to
Table 5-6. Reserved Port Numbers
