Accessible IP List
The Moxa switch uses an IP address-based filtering method to control access.
You may add or remove IP addresses to limit access to the Moxa switch. When the accessible IP list is enabled,
only addresses on the list will be allowed access to the Moxa switch. Each IP address and netmask entry can be
tailored for different situations:
• Grant access to one host with a specific IP address
For example, enter IP address 192.168.1.1 with netmask 255.255.255.255 to allow access to 192.168.1.1
only.
• Grant access to any host on a specific subnetwork
For example, enter IP address 192.168.1.0 with netmask 255.255.255.0 to allow access to all IPs on the
subnet defined by this IP address/subnet mask combination.
• Grant access to all hosts
Make sure the accessible IP list is not enabled. Remove the checkmark from Enable the accessible IP
list.
The following table shows additional configuration examples:

Mode (SET/ACT)
The DSL Ethernet extenders operate in pairs. One of the units needs to be configured as a CO and the other as
a CPE. In addition to manually assigning both connected pairs by selecting DIP switches, IEX also supports auto
negotiation mode with zero configuration. Users can take advantage of this breakthrough technology just
based on the DIP switch default setting as COs for both devices. The system will auto-negotiate and assign CPE
to one of the devices in each pair.
NOTE: CO/CPE auto negotiation only support in STD mode based on DIP switch setting
Setting Description Factory Default
Device terminal type SET: The value same as CO/CPE
DIP switch configuration
ACT: The value after pair
devices negotiation
CO/CO or CPE after negotiation
Turbo
The DSL Ethernet extender supports two communication modes; standard (STD) and turbo. The difference is
the transmission data rate, highest up to 5.7Mbps and 15.3Mbps for standard and turbo mode respectively. The
higher the transmission data rate, the shorter the connection distance. In other words, lower data rates can
extend the transmission over a longer distance.
Moxa Managed Ethernet Switch/Extender Featured Functions

In standard mode, the connection speed is decided once the connection is established between the CO and the
CPE based on signal-to-noise ratio (SNR). However, the transmission speed will be auto detected from
5696Kbps to 15.3Mbps. It should take less than 5 minutes to complete the training process.
Setting Description Factory Default
Turbo mode status Indicates whether turbo mode is
enabled or not based on DIP

Link Fault Pass-Through (IEX series only)
If the Ethernet or DSL connection is down, the device will not be notified that the connection has been
terminated. The device will continue to transmit packets and wait idly for a response that never arrives—and
the longer the wait, the higher the possibility that packets will be lost.
With link fault pass through (LFP), a troubleshooting function that drastically reduces the waiting time, enables
Moxa IEX products to force a link down status to prevent data loss.
Ethernet Link-Down Mode
If either the CO or CPE Ethernet port link is down, the IEX will disable the corresponding Ethernet connection
so that data can no longer be sent but keeps the DSL connection alive. As a result, data loss is minimized with
the topology change notice based on redundancy protocol issued by connected MOXA Ethernet Switches. Once
the Ethernet link is up again, the IEX will try to fast recover the connection without DSL re-training. The system
logs will record link up/down events.
DSL Link-Down Mode
When the DSL connection is down, the IEX will immediately disable both CO and CPE Ethernet connections to
avoid packets being sent through the failed path. The IEX will try to reestablish the Ethernet link when the DSL
connection is stable again. The system logs will record link up/down events.
Network Parameters
Network configuration allows users to configure both IPv4 and IPv6 parameters for management access over
the network. The Moxa switch supports both IPv4 and IPv6, and can be managed through either of these
address types.
A brief explanation of each configuration item is given below.

IEEE 1588 PTP
The following information is taken from the NIST website at http: //ieee1588.nist.gov/intro.htm:
“Time measurement can be accomplished using the IEEE Standard for a Precision Clock Synchronization
Protocol for Networked Measurement and Control Systems (IEEE 1588-2008) to synchronize real-time clocks
incorporated within each component of the electrical power system for power automation applications.
IEEE 1588, which was published in November 2002, expands the performance capabilities of Ethernet networks
to control systems that operate over a communication network. In recent years an increasing number of
electrical power systems have been using a more distributed architecture with network technologies that have
less stringent timing specifications. IEEE 1588 generates a master-slave relationship between the clocks, and
enforces the specific timing requirements in such power systems. All devices ultimately get their time from a
clock known as the grandmaster clock. In its basic form, the protocol is intended to be administration free.”
How does an Ethernet switch affect 1588 synchronization?
The following content is taken from the NIST website at http: //ieee1588.nist.gov/switch.htm:
“An Ethernet switch potentially introduces multi-microsecond fluctuations in the latency between the 1588
grandmaster clock and a 1588 slave clock. Uncorrected these fluctuations will cause synchronization errors.
The magnitude of these fluctuations depends on the design of the Ethernet switch and the details of the
communication traffic. Experiments with prototype implementations of IEEE 1588 indicate that with suitable
care the effect of these fluctuations can be successfully managed. For example, use of appropriate statistics in
the 1588 devices to recognized significant fluctuations and use suitable averaging techniques in the algorithms
controlling the correction of the local 1588 clock will be the good design means to achieve the highest time
accuracy.”
Can Ethernet switches be designed to avoid the effects of these
fluctuations?
A switch can be designed to support IEEE 1588 while avoiding the effects of queuing. In this case two
modifications to the usual design of an Ethernet switch are necessary:
Moxa Managed Ethernet Switch/Extender Featured Functions
3-13
1. The Boundary Clock and Transparent Clock functionalities defined by IEEE 1588 must be implemented
in the switch.
2. The switch must be configured such that it does not pass IEEE 1588 message traffic using the normal
communication mechanisms of the switch.
Such an Ethernet switch will synchronize clocks directly connected to one of its ports to the highest possible
accuracy.
NOTE
If the CM
-600-4TX-PTP module is not installed, then the EDS-600 only supports software-based IEEE 1588.
