or Force. When Auto, the switch will auto-negotiate the speed and the
duplex mode with the connected port. When Force, the administrator will
have to manually configure the speed in the Speed column and the
duplex mode in Duplex column to match with the connected port.

When Negotiation column is configured as Force, this column will be

available for you to choose the port link speed.

When Negotiation column is configured as Force, this column will be

available for you to choose the duplex mode of the port.

This feature allows the administrator to select flow control options. When

Disable, the receiving device will drop the packet if there is too much to
process. When Enable, once the device exceeds the input data rate of

another device, the receiving device will send a PAUSE frame which
halts the transmission of the sender for a specified period of time.

This feature allows the administrator to configure the security level for

managing this switch. If the security column is configured as On, the port
will accept only the first MAC address entry in Static MAC Add ress table

to access this switch and change the switch settings. If the security

column is configured as Off, any MAC address can access the switch

and change the switch settings.

4-6.2 Rate Limiting

This feature allows the administrator to set up every port’s bandwidth rate and packet limitation type.

This feature allows the administrator to select the packet type that needs
to be filtered for a certain port. The packet types available for selecting
include:

¾ Broadcast/Multicas t/Flooded Unicast
¾ Broadcast/Multicast
¾ Broadcast o nly

Broadcast/Multicast/Flooded Unicast, Broadcast/Multicast, and
Broadcast only are only for ingress packets. The egress rate only

supports All type.

All ports support port ingress and egress rate control. For example, if port
1 runs at 10Mbps, the administrator can set its effective egress rate as
1Mbps, and ingress rate is 500Kbps. The switch performs the ingress
rate by packet counter to meet the specified rate.

will be copied to the destination (mirror) port. The administrator can
select up to 7 monitor ports in the switch. The administrator can select
multiple source ports by checking the RX or TX boxes.

4-6.4 DHCP Server

DHCP stands for Dynamic Host Configuration Protocol, a protocol for assigning dynamic IP addresses to
devices on a network. With dynamic addressing, a device can have a different IP address every time it
connects to the network. In some systems, the device's IP address can even be changed while it is still
connected. DHCP also supports a mix of static and dynamic IP addresses. Dynamic addressing simplifies
network administration because the software keeps track of IP addresses rather than requiring an
administrator to manage the task. This means that a new computer can be added to a network without the

4-6.10 Port Trunking

Port trunking is the combination of several ports or network cables to expand the connection speed beyond
the limits of any one single port or network cable. Link Aggregation Control Protocol (LACP), which is a
protocol running on layer 2, provides a standardized means in accordance with IEEE 802.3ad to bundle
several physical ports together to form a single logical channel. All the ports within the logical channel or
so-called logical aggregator work at the same connection speed and LACP operation requires full-duplex
mode.

4-6.10.1 Aggregator Settings

This value is used to identify the active LACP. The switch with the

System Priority

Group ID

LACP

Work Ports

lowest value has the highest priority and is selected as the active
LACP peer of the trunk group.

There are 3 trunk groups available for configuration. The

administrator can assign the Group ID to the trunk group.

When enabled, the trunk group is using LACP. A port which joins an
LACP trunk group has to make an agreement with its member ports
first. Please notice that a trunk group, including member ports
distributed between two switches, has to enable the LACP function
of the two switches. When disabled, the trunk group is a static trunk
group. The advantage of having the LACP disabled is that a port
joins the trunk group without any handshaking with its member
ports; but member ports won’t know that they should be aggregated
together to form a logic trunk group.

This column field allows the administrator to type in the total
number of active ports up to four. With LACP trunk group, e.g. you
assign four ports to be the members of a trunk group whose work
ports column field is set as two; the exceed ports are
standby/redundant ports and can be aggregated if working ports
fail. If it is a static trunk group (non-LACP), the number of work ports
must equal the total number of group member ports.

responds only if it receives LACP protocol packets from the
opposite device.

A link having two passive LACP nodes will not perform dynamic LACP trunk since both ports
are waiting for an LACP protocol packet from the opposite device.

4-6.11 VLAN Configuration

A Virtual LAN (VLAN) is a logic networking group consisting of hosts with a common set of requirements that
communicate as if they were attached to the broadcast domain, regardless of their physical location. VLAN
allows for end stations to be grouped together even if they are not located on the same network switch.
Network reconfiguration can be realized through software instead of physically relocating devices.

HME-421E/423E supports both port-based VLAN and IEEE 802.1Q (Tag-based) VLAN. HME-421E/423E

VLAN operation mode if Disable by default.

4-6.11.1 Port-based VLAN

A port-based VLAN is formed by a group of switch ports which are not necessary located on the same switch.
A four-byte field in the header is used to identify the VLAN. Packets can go among only members of the
same VLAN group. All unselected ports are treated as belonging to another single VLAN. If the port-based
VLAN enabled, the VLAN-tagging will be ignored.

In order for an end station to send packets to different VLAN groups, it has to be either capable of tagging
packets it sends with VLAN tags, or attached to a VLAN-aware bridge that is capable of classifying and

4-19

tagging the packet with different VLAN ID based on not only default PVID but also other information about
the packet, such as the protocol.

4-6.11.2 IEEE 802.1Q Tag-based VLAN

Tag-based VLAN is an IEEE 802.1Q standard which allows to create a VLAN across devices from different
switch venders. IEEE 802.1Q VLAN uses a technique to insert a “tag” into the Ethernet frames. Tag contains
a VLAN Identifier (VID) that indicates the VLAN numbers.

All ports on the switch belong to default VLAN, VID is 1. The default VLAN can’t be deleted. The maximum
VLAN group is up to 64.

Virtual Local Area Network (VLAN) can be implemented on the switch to logically create different broadcast
domain.

When the 802.1Q VLAN function is enabled, all ports on the switch belong to default VLAN of VID 1, which
means they logically are considered as members of the same broadcast domain. The valid VLAN ID number
ranges from 1 to 4094. The amount of VLAN groups is up to 256 including default VLAN that cannot be
deleted.

Each member port of an 802.1Q VLAN group is on either an Access Link (non VLAN-tagged) or a Trunk Link
(VLAN-tagged). All frames on an Access Link carry no VLAN identification, while all frames on a Trunk Link
are VLAN-tagged. In addition to above-mentioned 2 types, there is the third mode—Hybrid. A Hybrid Link
can carry both VLAN-tagged frames and untagged frames. A single port is supposed to belong to one VLAN
group, except it is on a Trunk/Hybrid Link.

The technique of 802.1Q tagging inserts a 4-byte tag, including VLAN ID of the destination port—PVID, in
the frame. With the combination of Access/Trunk/Hybrid Links, the communication across switches also can
make the packet sent through tagged and untagged ports.

4-6.11.2.1 802.1Q Configuration

Select 802.1Q from the drop down list to configure Tag-based VLAN
settings.

Only when the VLAN members, whose Untagged VID (PVID) equals to

the value in this column, will have the permission to access the switch.

The default value is 0, meaning this limit is not enabled (all members in

different VLANs can access this switch).

GVRP (GARP VLAN Registration Protocol) is a protocol that facilitates
control of virtual local area networks (VLANs) within a larger network.

Enable GVRP

GVRP conforms to the IEEE 802.1Q specification, which defines a
method of tagging frames with VLAN configuration data. This allows
network devices to dynamically exchange VLAN configuration

4-21

information with other devices. For example, with GVRP function enabled
on two switches, the switches are able to automatically exchange the
information of their VLAN database. Therefore, the administrator doesn’t
need to manually configure whether the link is trunk or hybrid, the
packets belonging to the same VLAN can communicate across switches.
Mark this checkbox to enable GVRP protocol. This checkbox is available
while the VLAN Operation Mode is in 802.1Q mode.

Port To select the port you want to configure

This feature allows the administrator to decide a certain port to be an
Access Link, a Trunk Link, or a Hybrid Link.

¾ Access Link: A segment which provides the link path for one or more

stations to the VLAN-aware device. An Access Port (untagged port),
connected to the access link, has an untagged VID (also called
PVID). After an untagged frame gets into the access port, the switch
will insert a four-byte tag in the frame. The contents of the last 12-bit
of the tag is untagged VID. When this frame is sent out through any of
the access port of the same PVID, the switch will remove the tag from
the frame to recover it to what it was. Those ports of the same

Link Type

Untagged VID

Tagged VID

untagged VID are considered as the same VLAN group members.

¾ Trunk Link: A segment which provides the link path for one or more

VLAN-aware devices (switches). A Trunk Port, connected to the trunk
link, has an understanding of tagged frame, which is used for the
communication among VLANs across switches. Which frames of the
specified VIDs will be forwarded depend on the values filled in the
Tagged VID column field. Please insert a comma between two VIDs.

¾ Hybrid Link: A segment which consists of Access and Trunk links. The

hybrid port has both the features of access and trunk ports. A hybrid
port has a PVID belonging to a particular VLAN, and it also forwards
the specified tagged-frames for the purpose of VLAN communication
across switches.

This column field is available when Link Type is set as Access Link or
Hybrid Link. Assign a number ranging from 1 to 4094.

This column field is available when Link Type is set as Trunk Link or

Since the access port doesn’t have an understanding of tagged frames, the column field of

Tagged VID will not be available when the port is configured as an Access Link.

1. A trunk port doesn’t insert tag into an untagged frame, and therefore the untagged VID
column field is not available when the port is configured as a Trunk Link.

2. It’s not necessary to type ‘1’ in the tagged VID. The trunk port will forward the frames of
VLAN 1.

3. The trunk port has to be connected to a trunk/hybrid port of the other switch. Both the
tagged VID of the two ports have to be the same.

1. It’s not necessary to type ‘1’ in the tagged VID. The hybrid port will forward the frames of

QoS Policy

Priority Type

This feature allows the administrator to select QoS policy.

Use an 8, 4, 2, 1 weighted fair queuing scheme:

The switch will follow 8:4:2:1 proportion to process priority queue from
the highest to the lowest. For example: the switch will process 8 highest
priority packets first, and then 4 second highest priority packets, and then
2 low priority packets, and then the 1 lowest priority packets.

Use the strict priority scheme:

The switch will process the packets with the highest priority first. The
switch won’t continue to process the second highest priority packets until
the highest priority ones have been all processed.

This feature allows the administrator to configure each port’s priority type.
There are 5 types available:

¾ Port-based: this port priority will follow the default port priority that

administrator has configured: High, middle, low, or lowest

¾ COS only: this port priority will only follow the COS priority rules that

administrator has configured.

¾ TOS only: this port priority will only follow the TOS priority rules that

administrator has configured.

¾ COS first: this port priority will follow the COS priority rules that

administrator has configured first, and then follow other priority
rules.

¾ TOS first: this port priority will follow the TOS priority rules that

administrator has configured first, and then follow other priority
rules.

COS Priority

TOS Priority

This feature allows the administrator to configure each port’s default port
priority. There 4 types of priority available: High, Middle, Low, Lowest.

This feature allows the administrator to configure the COS priority level 0
to 7.

The switch provides 0 to 63 TOS priority levels. Each level has 4 types of
priority – high, mid, low, and lowest. The default priority value is “Lowest”
for each level. When an IP packet is received, the switch will check the
TOS level value in the IP packet received. For example: the administrator

4-24

set the TOS level 25 to be high. The port 1 is following the TOS priority
policy only. When the packet received by port 1, the switch will check the
TOS value of the received IP packet. If the TOS value of received IP
packet is 25 (priority = high), and then the packet priority will have the
highest priority.

4-6.13 IGMP Configuration

The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP). IGMP
Snooping mode allows the switch to forward multicast packets to appropriate ports. The switch will detect
IGMP queries when multicast packets come in and then report back with packets indicating which port is
willing to accept the multicast packets. With this function, network traffic can be limited without unwanted
packets being sent to certain ports. IGMP has three fundamental types of messages as follows:

Message Description
Query

Report

A message sent from the querier (IGMP router or switch) asking for a
response from each host belonging to the multicast group.

A message sent by a host to the querier to indicate that the host wants to

Link Layer Discovery Protocol (LLDP) is defined in the IEEE 802.1AB, which is an emerging standard
providing a solution for the configuration issues caused by expanding LANs. LLDP specifically defines a
standard for Ethernet network devices such as switches, routers and wireless LAN access points to
advertise information about themselves to other nodes on the network and store the information they
discover. LLDP runs on all 802 media. The protocol runs over the data-link layer only, allowing two systems
running different network layer protocols to learn about each other.

LLDP Protocol This allows the administrator to enable or disable LLDP function.

4-6.16 Rapid Spanning Tree Protocol Configuration (RSTP)

The Rapid Spanning Tree Protocol (RSTP) is an evolution of the Spanning Tree Protocol and provides for
faster spanning tree convergence after a topology change. HME-421E/423E also supports STP and will auto
detect the connected device whether it is running STP or RSTP protocol.

function. The parameters will be available for configuration after the
RSTP function is enabled.

This is the value used to identify the root bridge. The bridge with the
lowest value has the highest priority and will be selected as the root. If
this value has been changed, the switch must be rebooted for the new
settings to be in effect. The value must be multiple of 4096 according to
the protocol standard.

This value is the seconds a bridge waits for without receiving spanning
tree messages before attempting to reconfigure. Enter a value between 6
and 40.

This value is the time in seconds that controls when the switch sends out
the BPDU packet to check RSTP current status. Enter a value between 1

4-6.17 X-Ring Configuration

HME-421E/423E provides redundant self-recovery mechanism named as X-Ring. When compared with the
commercial standard redundant technologies like STP or RSTP, the X-Ring can effectively reduce the
recovery time to less than 300ms. The Ring Topology must be applied to all the connected switches.

When all switches are connected in a ring topology with X-Ring function enabled, one of the switches will be
appointed as “Ring Master.” The ring master will monitor the ring’s health to make sure the ring is working
properly. Once a failure is detected by the ring master, the ring master will activate the blocked backup path
within milliseconds to replace the faulty primary transmission path to make sure the ring will continue to work.

In the X-Ring topology, every switch should enable X-Ring function and assign two member ports to form the

4-32

Configuration Using a Web Browser

ring. Only one switch in the X-Ring group would be set as a backup switch, and one of its two member ports
on this backup switch would be blocked, called the backup port, while the other member port is called a
working port. Other switches are called working switches and their two member ports are called working
ports. When the network connection fails, the backup port will automatically become a working port to
resume the connection.

HME-421E/423E has a R.M DIP switch on is front panel that would allow the administrator to configure this
switch as the Ring Master or not. When the switch is set to be the Ring Master, the X-Ring configuration
screen will display a message saying this switch is the Ring Master. The Ring Master will be responsible for
negotiating and placing commands to other switches in the X-Ring group. If by accident there are 2 or more
switches are being configured as the Ring Master, then the software will automatically select the switch with
the lowest MAC address number as the Ring Master.

HME-421E/423E also supports Couple Ring, a power management function that allows 2 or more X-Ring
groups to be connected to each other to offer more advanced redundancy. Dual Homing function is another
advanced management feature that HME-421E/423E offers, an advanced redundancy network solution by
connecting switches running in different redundant protocols such as IEEE 802.1w Rapid Spanning Tree
Protocol and X-Ring to extend the network redundant coverage. HME-421E/423E also comes with a new
advanced ring redundancy feature called Dual Ring. Dual Ring can handle 2 rings in the system and has the
ability to recover from failure within 20 milliseconds.

802.1X is an IEEE standard, which provides port-based authentication. It involves communications between
a supplicant, authenticator, and authentication server. The supplicant is often software on a client device,
such as a laptop, the authenticator is a wired Ethernet switch or wireless access point, and an authentication
server is generally a RADIUS database. The authenticator acts like a security guard to a protected network.
The supplicant (i.e., client device) is not allowed access through the authenticator to the protected side of the
network until the supplicant’s identity is authorized.

5-1 X-Ring Application

X-Ring is an advanced industrial redundant technology introduced by Ethernet Direct. When compared with
the commercial standard redundant technologies like STP or RSTP, the X-Ring can effectively reduce the
recovery time to less than 300ms. The ring topology must be applied to all the connected switches. When all
switches are connected in a ring topology with X-Ring function enabled, on of the switches will be appointed
as Ring Master. The Ring Master will monitor the ring’s health to make sure the ring is working properly.
Once a failure is detected by the Ring Master, the Ring Master will activate the blocked backup path within
milliseconds to replace the faulty primary transmission path to make sure the ring topology will continue to
work. In addition, there are multiple Ring Masters allowed in the ring connections. Please see below figure 1
for the example of an X-Ring connection.

Figure 1 Example of X-Ring Connection Diagram

5-2 Couple Ring

In the real world implementation, there are cases that require two X-Ring groups to be connected together to
ensure redundant protection. Couple Ring technology was introduced by Ethernet for this requirement. With
Couple Ring function, each X-Ring group will need to assign two switches with 2 extra ports to achieve the
structure. For this reason, the total switches needed for the Couple Ring to work will be four switches, and
each switch is assigned with four ports for completing a Couple Ring (including the two X-Ring ports per
switch). Please see below figure 2 for example of Couple Ring connection.

Network Applications

Figure 2 Example of Couple Ring Connection

5-3 Dual Homing

Dual Homing provides an advanced redundancy network solution by connecting switches running in different
redundancy protocols such as IEEE 802.1w Rapid Spanning Tree Protocol and X-Ring to extend the network
redundant coverage. Dual Homing feature can ensure a single or two X-Ring groups with redundant backup
when connected to a backbone switch. Redundancy is achieved by connecting two ports from two separate
switches using X-Ring ring protocol with two ports of managed switches using other redundancy protocol. An
active link where data is transmitted is connected with on port in the switch. The other port connected with
another switch is a hot standby link. The hot standby link is being constantly monitored and it will be switched
over within seconds once the active link is disconnected or broken. This approach can open up LAN design
options and expand device choices. For example, it can permit any industrial PLC devices with Ethernet
interfaces to be part of a resilient network. With the implementation of Dual Homing feature, the X-Ring
group will be allowed to connect to these backbone core switches and without sacrificing its redundant
protections. Below, we show an example of connection diagram on how Dual Homing can be connected with
1 or 2 X-Ring groups.

5-4 Dual Ring

Although Ethernet Direct provides the Dual Homing technology for the industrial customers who may need to
connect their switches from a field environment to the centralized backbone, some users may not deploy
Cisco or HP switches. In some application cases, customers would like their backbone switches to be the
same as those switches in their field environment equipped with industrial-grade protection and yet serve as
the backbone network. Considering the needs, Ethernet Direct released new redundant technology called

Dual Ring.

The Dual Ring is recommended when the concern is “cost” or small projects with lesser amount of switches.
Dual Ring allows the connection up to two ring groups to the central backbone and the configuration will only
exist in those switches with minimum 8 ports availability.

Troubleshooting

Make sure you are using the right power cord/adapter (DC 12-48V). Do not use power
adapters with DC output higher than 48V. Or it will short circuit the switch.

Select the proper UTP cables to construct your network. Please check that you are using the
right cables. Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cables for RJ-45
connections: 100Ω Category 3, 4 or 5 cables for 10Mbps connections, and 100Ω Category 5
cables for 100Mbps. Also be sure that the length of any twisted-pair connection does not
exceed 100 meters (328 feet).

Diagnostic LED indicators located on the front panel of the switch can help users to easily
monitor the switch.

IF the power indicator does not light on when the power cord is plugged in, you may have a
problem with power cord. Then check for loose power connections, power losses or surges at
power outlet. IF you still cannot resolve the problem, contact your local dealer for assistance.

If the switch LED indicators are normal, the cables are connected correctly, and the packets
still cannot transmit, please check your system’s Ethernet devices’ configuration or status.
