Chapter 2 Getting Started
This chapter explains how to access EDS-726 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-726 to a PC’s COM port, can be used if
you do not know EDS-726’s IP address. The Telnet console and web browser connection methods
can be used to access EDS-726 over an Ethernet LAN, or over the Internet.
The following topics are covered:
RS-232 Console Configuration (115200, None, 8, 1, VT100)
Configuration by Telnet Console
Configuration by Web Browser
Disabling Telnet and Browser Access

NOTE
NOTE
Connection Caution!
1. You cannot connect to EDS-726 simultaneously by serial console and Telnet.
2. You can connect to EDS-726 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-726.
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-726’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, take the following steps to access the RS-232 Console
utility.
1. From the Windows desktop, click on Start Æ Programs Æ PCommLite2.5 Æ Terminal
Emulator.
2. Select Open under Port Manager to open a new connection.

Configuration by Telnet Console
You may use Telnet to access EDS-726’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-726, you need to make sure that the PC host and EDS-726 are on the same
logical subnetwork. To do this, check your PC host’s IP address and subnet mask. By default,
EDS-726’s IP address is 192.168.127.253 and EDS-726’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-726’s management and monitoring functions from a PC host connected to the same
LAN as EDS-726, you must make sure that the PC host and EDS-726 are on the same logical
subnetwork.
Before accessing the console utility via Telnet, first connect one of EDS-726’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-726’s default IP is 192.168.127.253.
Follow the steps below to access the console utility via Telnet.
1. Click on Start Æ Run, and then telnet to EDS-726’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-726’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-726 to a PC’s COM port, can be used if you do not know EDS-726’s
IP address. The Telnet console and web browser connection methods can be used to access
EDS-726 over an Ethernet LAN, or over the Internet.
The Web Console is the most user-friendly way to configure EDS-726. 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.

Accessible IP
Moxa EDS-726 uses an IP address-based filtering method to control access to EDS-726 units.
Accessible IP Settings allows you to add or remove “Legal” remote host IP addresses to prevent
unauthorized access. Access to EDS-726 is controlled by IP address. That is, if a host’s IP address
is in the accessible IP table, then the host will be allowed access to the EDS-726. 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-726
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-726
E.g., enter “192.168.1.0/255.255.255.0” to allow access to all IPs on the subnetwork defined
by this IP address/subnet mask combination.
y Any host can access the EDS-726
Disable this function by not checkmarking the “Enable the accessible IP list” checkbox.
The following table shows additional configuration examples:

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-726’s Port Trunking feature allows devices to communicate by aggregating up to four links
in parallel, with a maximum of eight ports for each link. If one of the eight ports fails, the other
seven ports will provide back up and share the traffic automatically.
Port trunking can be used to combine up to eight ports between two EDS-726 switches. If all ports
on both switch units are configured as 100BASE-TX and they are operating in full duplex, the
potential bandwidth of the connection will be 1600 Mbps.

The Port Trunking Concept
EDS-726 allows a maximum of 4 trunk groups, with a maximum of 8 trunk ports for each trunk
group. You can configure the trunk group to be “Static” or “LACP.” Once the trunk group is set to
“LACP,” all of the ports making up that group will be set to LACP enabled. The ports in the
“Static” trunk groups, and all the non-trunk ports that do not belong to any trunk group, will be set
to LACP disabled. When the port is set to LACP enabled, it will exchange LACPDU with its link
partner, and will result in “Forwarding.” If all of the ports in the same group are “Blocked” or
“Disabled” or “Down” (link-down), the trunk group will not work, and the user will see “LACP
Failed” for that trunk group in the user interface.
EDS-726 allows you to set more than 8 ports in one trunk group. Those ports that exceed the port
limit (i.e., 8) will be set as “Standby” ports, as defined by the IEEE 802.3ad protocol. A “Standby”
port is an LACP enabled port that is attached to a trunk group, but is not functioning yet. The port
state of such ports will be listed as “Blocking.” A trunk group on “Standby” cannot be used by
another trunk group, or be activated as an individual link. The standby port will start working as a
normal trunk port whenever any other trunk port in the same group stops functioning, such as
when a port fails to transmit or receive packets due to a physical fault. EDS-726 allows a
maximum of 4 “Standby” ports for each LACP trunk group, so that a maximum of 12 ports can be
assigned to each LACP trunk group. A Static trunk group cannot have “Standby” ports. This
means that a Static trunk group can only have a maximum of 8 ports in the group.
Port Trunking applies to connections between backbone devices as well as to connections in other
network areas where traffic bottlenecks exist. Port Trunking provides the following benefits:
y Gives you more flexibility in setting up your network connections, since the bandwidth of a
link can be expanded to 8 times the original bandwidth.
y Provides redundancy—if one link is broken, the remaining trunked ports share the traffic
within this link. EDS-726 allows a maximum of 4 “Standby” ports for each LACP trunk group.
In another words, a maximum of 12 ports can belong to each LACP trunk group. These four
standby ports provide redundancy to a normal 8-port trunk whenever any other trunk port in
the same group does not function properly, such as when the port fails to transmit or receive
packets due to a physical fault
y Load sharing—MAC Client traffic may be distributed across multiple links.
Keep the following points in mind when configuring port trunking:
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.
y Up to 4 port trunking groups (designated Trk1, Trk2, Trk3, Trk4) can be used for each
EDS-726.
3-13
EDS-726 Series User’s Manual Featured Functions
y Up to 8 ports can be inserted into each port trunk group. EDS-726 allows a maximum of 4
“Standby” ports for each LACP trunk group. In another words, a maximum of 12 ports can
belong to each LACP trunk group.
y The same transmission speed must be assigned to all ports belonging to one port trunking
group. E.g., 100M Full, 100M Half, 10M Full, or 10M Half. The auto-negotiation function
should be disabled for these ports.
y Full duplex operation only—Link Aggregation is supported only on point-to-point links with
MACs operating in full duplex mode.
y Multipoint Aggregations—The mechanisms specified in this clause do not support
aggregations among more than two systems.
When you activate port trunking settings, some advanced functions will either be set to factory
default values, or disabled:
y Port stat, such as transmitting speed, duplex, and flow control will be set to the factory
defaults.
y Communication Redundancy will be set to the factory default.
y 802.1Q VLAN will be set to the factory default and will be disabled.
y Multicast Filtering will be set to the factory default.
y Port Lock will be set to the factory default and will be disabled.
y Set Device IP will be set to the factory default
y Mirror Port will be set to the factory default and will be disabled.
Configuring Port Trunking
The Port Trunking Settings page is used to assign ports to a Trunk Group.
Step 1: Select Trk1, Trk2, Trk3, or Trk 4 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, checkmark to select specific ports.
Step 4: Use the Up / Down buttons to add/remove designated ports to/from a trunk group.
