Chapter 2 Getting Started

This chapter explains how to access EDS-518A for the first time. There are three ways to access
the switch: serial console, Telnet console, and web browser. The serial console connection method,
which requires using a short serial cable to connect EDS-518A to a PC’s COM port, can be used if
you do not know EDS-518A’s IP address. The Telnet console and web browser connection
methods can be used to access EDS-518A over an Ethernet LAN, or over the Internet.

The following topics are covered:

 RS-232 Console Configuration (115200, None, 8, 1, VT100)
 Configuration using a Telnet Console
 Configuration using a Web Browser
 Disabling Telnet and Browser Access

NOTE

NOTE

Connection Caution!

1. You cannot connect to EDS-518A simultaneously by serial console and Telnet.

2. You can connect to EDS-518A simultaneously by web browser and serial console, or by web

browser and Telnet.
However, we strongly suggest that you do NOT use more than one connection method at the
same time. Following this advice will allow you to maintain better control over the
configuration of your EDS-518A.

We recommend using MOXA PComm Terminal Emulator, which can be downloaded free of
charge from MOXA’s website.

Before running PComm Terminal Emulator, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to
connect EDS-518A’s RS-232 Console port to your PC’s COM port (generally COM1 or COM2,
depending on how your system is set up).

After installing PComm Terminal Emulator, perform the following steps to access the RS-232

Console utility.

1. From the Windows desktop, click Start Æ Programs Æ PCommLite2.5 Æ Terminal

Configuration using a Telnet Console

You may use Telnet to access EDS-518A’s console utility over a network. To be able to access
EDS’s functions over the network (by Telnet or Web Browser) from a PC host that is connected to
the same LAN as EDS-518A, you need to make sure that the PC host and EDS-518A are on the
same logical subnet. To do this, check your PC host’s IP address and subnet mask. By default,
EDS-518A’s IP address is 192.168.127.253 and EDS-518A’s subnet mask is 255.255.0.0 (for a
Class B network). If you do not change these values, and your PC host’s subnet mask is

255.255.0.0, then its IP address must have the form 192.168.xxx.xxx. On the other hand, if your
PC host’s subnet mask is 255.255.255.0, then its IP address must have the form 192.168.127.xxx.

NOTE

NOTE

NOTE

To use EDS-518A’s management and monitoring functions from a PC host connected to the same
LAN as EDS-518A, you must make sure that the PC host and EDS-518A are on the same logical
subnet.

Before accessing the console utility via Telnet, first connect one of EDS-518A’s RJ45 Ethernet
ports to your Ethernet LAN, or directly to your PC’s Ethernet NIC. You can establish a
connection with either a straight-through or cross-over Ethernet cable.

EDS-518A’s default IP is 192.168.127.253.

Perform the following steps to access the console utility via Telnet.

1. Click Start Æ Run, and then telnet to EDS-518A’s IP address from the Windows Run

window. (You may also issue the telnet command from the MS-DOS prompt.)

2. Type 1 to choose ansi/vt100, and then press Enter.

Chapter 3 Featured Functions

This chapter explains how to access EDS-518A’s various configuration, monitoring, and
administration functions. There are three ways to access these functions: RS-232 console, Telnet
console, and web browser. The serial console connection method, which requires using a short
serial cable to connect EDS-518A to a PC’s COM port, can be used if you do not know
EDS-518A’s IP address. The Telnet console and web browser connection methods can be used to
access EDS-518A over an Ethernet LAN, or over the Internet.

The Web Console is the most user-friendly way to configure EDS-518A. In this chapter, we use
the Web Console interface to introduce the functions. There are only a few differences between the
Web Console, Serial Console, and Telnet Console.

The following topics are covered in this chapter:

 Configuring Basic Settings

Accessible IP

MOXA EDS-518A uses an IP address-based filtering method to control access to EDS-518A
units.

Accessible IP Settings allows you to add or remove “Legal” remote host IP addresses to prevent
unauthorized access. Access to EDS-518A is controlled by IP address. If a host’s IP address is in
the accessible IP table, then the host will be allowed access to the EDS-518A. You can allow one
of the following cases by setting this parameter:

y Only one host with the specified IP address can access the EDS-518A

E.g., enter “192.168.1.1/255.255.255.255” to allow access to just the IP address 192.168.1.1.

y Any host on a specific subnetwork can access the EDS-518A

E.g., enter “192.168.1.0/255.255.255.0” to allow access to all IPs on the subnet defined by
this IP address/subnet mask combination.

y Any host can access the EDS-518A

Disable this function by deselecting the Enable the accessible IP list option.

The following table shows additional configuration examples:

Factory Default

The Factory Default function is included to give users a quick way of restoring EDS-518A’s
configuration settings to their factory default values. This function is available in the Console
utility (serial or Telnet), and Web Browser interface.

NOTE

After activating the Factory Default function, you will need to use the default network settings to
re-establish a web-browser or Telnet connection with your EDS-518A.

Using Port Trunking

Link Aggregation allows one or more links to be aggregated together to form a Link Aggregation
Group. A MAC client can treat Link Aggregation Groups as if they were a single link.

EDS-518A’s Port Trunking feature allows devices to communicate by aggregating up to 3 trunk
groups, with a maximum of 8 ports for each group. If one of the 8 ports fails, the other seven ports
will provide back up and share the traffic automatically.

Port trunking can be used to combine up to 8 ports between two EDS-518A switches. If all ports
on both switch units are configured as 100BaseTX and they are operating in full duplex, the
potential bandwidth of the connection will be 1600 Mbps.

The Port Trunking Concept

MOXA has developed a proprietary Port Trunking protocol that provides the following benefits:

y Gives you more flexibility in setting up your network connections, since the bandwidth of a

link can be doubled, tripled, or quadrupled.

y Provides redundancy—if one link is broken, the remaining trunked ports share the traffic

within this trunk group.

y Load sharing—MAC Client traffic may be distributed across multiple links.
y To avoid broadcast storms or loops in your network while configuring a trunk, first disable or

disconnect all ports that you want to add to the trunk or remove from the trunk. After you
finish configuring the trunk, enable or re-connect the ports.

3-11

EDS-518A Series User’s Manual Featured Functions

If all ports on both switch units are configured as 100BaseTX and they are operating in full duplex,
the potential bandwidth of the connection will be up to 1.6 Gbps on the EDS-518A. This means
that users can connect one EDS to another EDS by Port Trunking to double, triple, or quadruple
the bandwidth of the connection.

When configuring Port Trunking, note that:
Each EDS-518A can set a maximum of 3 Port Trunking groups (Trk1/Trk2, 2 trunk groups for

10/100M ports and Trk3 for Gigabi t port s )
When you activate Port Trunking settings, some advanced functions that you setup with the

original ports will either be set to factory default values, or disabled:

y Communication Redundancy will be set to the factory default
y Traffic Prioritization will be set to the factory default
y Port-based VLAN or 802.1Q VLAN will be set to the factory default
y Multicast Filtering will be set to the factory default
y Rate Limiting will be set to the factory default
y Port Access Control will be set to the factory default
y Email and Relay Warning will be set to the factory default
y Set Device IP will be set to the factory default
y Mirror Port will be set to the factory default

You can setup these features again on your Trunking Port.

Configuring Port Trunking

The Port Trunking Settings page is used to assign ports to a Trunk Group.

Step 1: Select Trk1, Trk2, or Trk3 from the Trunk Group drop-down box.
Step 2: Select Static, or LACP from the Trunk Type drop-down box.
Step 3: Under Member Ports and Available Ports, select the specific ports.
Step 4: Use the Up / Down buttons to add/remove designated ports to/from a trunk group.

Configuring SNMP

EDS-518A supports SNMP V1/V2c/V3. SNMP V1, and SNMP V2c use a community string
match for authentication, which means that SNMP servers access all objects with read-only or

read/write permissions using the community string public/private (default value). SNMP V3,

which requires you to select an authentication level of MD5 or SHA, is the most secure protocol.
You can also enable data encryption to enhance data security.

SNMP security modes and security levels supported by EDS-518A are shown in the following
table. Select the security mode and level that will be used to communicate between the SNMP
agent and manager.
