CONNECTING THE UNIT
For 10Base-T ports, plug a Category 3 (or greater) twisted pair cable into the M12 connector. For
100Base-T ports, plug a Category 5 (or greater) twisted pair cable into the M12 connector. Connect
the other end to the far end station. Verify that the LNK LED’s are ON once the connection has
been completed. To connect any other port to another Switch or Repeater, use a standard Cat5
straight through or crossover cable.
Warning: Creating a port to port connection on the same switch (i.e. loop) is an illegal operation
and will create a broadcast storm which will crash the network!

OVERVIEW OF ADVANCED FEATURES
Mode of Operation
Each port on the switch can be configured into different modes of operation as shown below:
Copper Ports: 100Base Fiber Ports:
- Half Duplex - Full Duplex
- Full Duplex
- Auto Negotiation
Half Duplex
In half duplex mode, the CSMA/CD media access method is the means by which two or more stations share
a common transmission medium. To transmit, a station waits (defers) for a quiet period on the medium (that
is, no other station is transmitting) and then sends the intended message in bit-serial form. If, after initiating
a transmission, the message collides with that of another station, then each transmitting station intentionally
transmits for an additional predefined period to ensure propagation of the collision throughout the system.
The station remains silent for a random amount of time (back-off) before attempting to transmit again.
Full Duplex
Full duplex operation allows simultaneous communication between a pair of stations using point-to-point
media (dedicated channel). Full duplex operation does not require that transmitters defer, nor do they
monitor or react to receive activity, as there is no contention for a shared medium in this mode.
Auto Negotiation
In Auto Negotiation mode, the port / hardware detects the mode of operation of the station that is connected
to this port and sets its mode to match the mode of the station.
Port Mirroring
A Mirroring Port is a dedicated port that is configured to receive the copies of Ethernet frames that are being
transmitted out and also being received in from any other port that is being monitored. ‘Mirrored Data Only’
can be selected and this selects for mirrored data only to be transmitted to the destination port, as opposed to
mirrored data and whatever other data is otherwise destined for the destination Port.
Port Trunking
Port Trunking is the ability to group two network ports to increase the bandwidth between two machines
(switch or any work station). This feature allows grouping of high-speed connectivity and provides
redundant connection between switches, so that a trunk can act as a single link between the switches.
Quality of Service (QoS)
Quality of service (QoS) refers to resource reservation control mechanism s. Quality of service is the ability
to provide different priority to different applications, users, or data flows. Quality of service guarantees are
important if the network capacity is insufficient, especially for real-tim e streaming multimedia applications
(Revised 2014-03-31) Page 18 of 170
such as voice over IP, online games and IP-TV, since these often require fixed bit rate and are delay
sensitive, and in networks where the capacity is a limited resource, for example in cellular data
communication. In the absence of network congestion, QoS mechanisms are not required.
Each of these three QOS methods below is included or not based on the settings on the relevant browser
page:
1) Force High Priority (Port Based),
2) IEEE802.1p (Tagged QOS), or
3) DSCP (differentiated services code points) (RFC 2474).
When Force High Priority is enabled, the port based priority is included in the decision for all ports and all
frames received on a port will use the default QOS priority for that port in the decision. For example, if it is
desired to have ingress frames on a port egress to the highest priority transmit queue regardless of other
factors, then enable Force High Priority and the port's Priority will be 7.
Virtual LAN
The switch provides support for setting up tagged Virtual LANs (Local Area Networks). A port may belong
to any number of Virtual LANs. The VLAN membership of a device is determined by the VLAN(s) that
have been defined for the port to which the device is connected. If a device should move from one port to
another, it loses its current VLAN membership and inherits that of the new port it is connected to.
VLANs facilitate easy administration of logical groups of devices that can communicate as if they were on
the same LAN. Traffic between VLANs is restricted, unless the ports are explicitly configured as
overlapping VLANs. Switches forward unicast, multicast, and broadcast traffic only on LAN segments that
serve the VLAN to which the traffic belongs.
A Default Virtual LAN (VID=1) exists to which a port, which is not a member of any other Virtual LAN,
will belong. This allows the switch to operate as a ‘normal’ switch when it is used in a network. A port is
automatically removed from the Default VLAN when it is reconfigured to belong to another Virtual LAN,
because that is the most common operation. But, if desired, the port can be included in VLAN 1 by
configuring VLAN 1 last.
If switch ports are configured to transmit and receive untagged frames, end devices are able to communicate
throughout the LAN. Using Tagged VLANs, the switch has the ability to take non-tagged packets in some
ports, add a VLAN tag to the packet and send it out tagged ports on the switch. The VLANs can also be
configured to accept tagged packets in tagged ports, strip the tags off the packets, and send the packets back
out other untagged ports. This allows a network administrator to set up the switch to support devices on the
network that do not support VLAN Tagged packets. The administrator can also set up the ports to discard
any packets that are tagged or to discard any packets that are untagged based on a hybrid VLAN of both
tagged and untagged ports, and using the VLAN Ingress Filter on the switch.
For each switch port there is one and only one PVID (port VLAN ID) setting. If an incoming frame is
untagged and untagged frames are being accepted, then that frame will inherit the tag of the PVID value for
that port. Subsequent switch routing and treatment will be in accordance with that VLAN switch map. By
configuring PVIDs properly and configuring for all frames to exit untagged, the switch can achieve a ‘port
VLAN’ configuration in which all frames in and out can be untagged, thus not requiring external devices to
be VLAN cognizant.
To understand how a VLAN configuration will perform, first look at the port on which the frame enters the
switch, then the VLAN ID (if the frame is tagged) or the PVID (if the frame is untagged). The VLAN
(Revised 2014-03-31) Page 19 of 170
defined by the VID or PVID defines a VLAN group with a membership of ports. This membership
determines whether a port is included or excluded as to frame egress from the switch.
The 708M12 & 716M12 Series switches also have the ability to allow overlapping VLANs. Overlapping
VLANs give the user the ability to have one or more ports share two or more VLAN groups. For more
information and examples on how this could be implemented, please see the ‘VLAN Configuration
Examples’ in this document, and/or our website’s technical documents. Note that RSTP on overlapping
VLANs is not supported and the system will automatically disable RSTP on all but the lowest VID VLANs
that have overlapping ports.
Rapid Spanning Tree Protocol
The Rapid Spanning Tree Protocol as specified in IEEE 802.1D-2004 is supported. One Spanning Tree per
non-overlapping VLAN is supported. The Rapid Spanning Tree Protocol (RSTP) supersedes the Spanning
Tree Protocol (STP) which was described in IEEE 802.1D-1998. The RSTP is used to configure a simply
connected active network topology from the arbitrarily connected bridges of a bridged network. Bridges
effectively connect just the LANs to which their forwarding ports are attached. Ports that are in a blocking
state do not forward frames. The bridges in the network exchange sufficient information to automatically
derive a spanning tree.
RSTP allows for much quicker learning of network topology changes than the older STP. RSTP supports
new and improved features such as rapid transition to forwarding state. RSTP also sends out new BPDUs
every hello time instead of just relaying them. RSTP interoperates with older STP switches by falling back
to the older STP when the older BPDUs are detected on bridge ports. The user can also manually configure
bridge ports to use the older STP when desired.
SNMP Traps
The 700 Series switch supports up to 5 SNMP Trap Stations to which SNMP Traps will be sent. The switch
supports five standard traps; Link Up, Link Down, Cold Start, Warm Start and Authentication Errors.
SNMP Traps will be sent to all the trap stations configured on the switch when the corresponding trap is
enabled.
IGMP Snooping
IGMP Snooping is enabled by default, and the switch is Plug and Play for IGMP. IGMP snooping provides
intelligent network support for multicast applications. In particular, unneeded traffic is reduced. IGMP
Snooping is configured via the web console and if enabled, operates dynamically upon each power up.
Also, there can be manual only or manual and dynamic operation. Note that “static multicast group
address” can be used whether IGMP Snooping is enabled or not.
IGMP Snooping will function dynamically without user intervention. If some of the devices in the LAN do
not understand IGMP, then manual settings are provided to accommodate them. The Internet Group
Management Protocol (IGMP) is a protocol that provides a way for a computer to report its multicast group
membership to adjacent ‘routers’. In this case N-Tron 700 Series switches provide router-like functionality.
Multicasting allows one computer to send content to multiple other computers that have identified
themselves as interested in receiving the originating computer's content. Multicasting can be used to
transmit only to an audience that has joined (and not left) a multicast group membership. IGMP version 2 is
formally described in the Internet Engineering Task Force (IETF) Request for Comments (RFC) 2236.
IGMP version 1 is formally described in the Internet Engineering Task Force (IETF) Request for Comments
(RFC) 1112. The 700 Series supports v1 and v2.

N-Ring
N-Ring is enabled by default, and the switch is Plug and Play for N-Ring except that initially one must
enable an N-Ring enabled device to be the N-Ring Manager for a given N-Ring. Subsequently, N-Ring
operates dynamically upon each power up. Using N-Tron's proprietary N-Ring technology offers expanded
ring size capacity, detailed fault diagnostics, and a standard healing time of 30ms. The N-Ring Manager
periodically checks the health of the N-Ring via health check packets. If the N-Ring Manager stops
receiving the health check packets, it times out and converts the N-Ring to a backbone within 30ms. When
using all N-Ring enabled switches in the ring, a detailed ring map and fault location chart is also provided
on the N-Ring Manager’s web browser. N-Ring status is also sent from the N-Ring Manager to the N-View
OPC Server to identify the health status of the ring. Up to 250 N-Ring enabled switches can participate in
one N-Ring topology. Switches that do not have N-Ring capability may be used in an N-Ring, however the
ring map and fault location chart cannot be as detailed at these locations.
N-Link
The purpose of N-Link is to provide a way to redundantly couple an N-Ring topology to one or more other
topologies, usually other N-Ring topologies. Each N-Link configuration requires 4 switches: N-Link
Master, N-Link Slave, N-Link Primary Coupler, and N-Link Standby Coupler. N-Link will monitor the link
status of the Primary and Standby Coupler links. While the Primary Coupler link is healthy, it will forward
network traffic and the Standby Coupler link will block network traffic. When a problem is detected on the
Primary Coupler link, the Primary Coupler link will block network traffic and the Standby Coupler link will
forward network traffic. While the N-Link Master and Slave are in communication via the Control link,
only one Coupler link (Primary or Standby) will forward network traffic while the other Coupler link will
block network traffic.
CIP
The CIP (Common Industrial Protocol) feature allows N-Tron switches to directly provide switch
information and configuration access to Programmable Logic Controller (PLC) and Human Machine
Interface (HMI) applications via a standardized communication protocol. For example, a PLC may be
programmed to monitor port links or N-Ring status and cause a status indicator to turn red on an HMI if a
port goes link down or if N-Ring has a fault. CIP is formally described in ODVA Publication Number
PUB00001 (Volume 1: Common Industrial Protocol (CIP™)), and Publication Number: PUB00002
(Volume 2: EtherNet/IP Adaptation of CIP). N-Tron provides EDS and ICO files. N-TRON_CIP_Tags.pdf
is for a particular environment, but reveals the tags available.
DHCP
The Dynamic Host Configuration Protocol (DHCP) provides configuration parameters to Internet hosts.
DHCP is built on a client-server model, where designated DHCP server hosts allocate network addresses
and deliver configuration parameters to dynamically configured hosts. DHCP is controlled by RFC 2131.
The N-Tron DHCP Switch can be configured to be a DHCP Client. Alternately the N-Tron DHCP switch
can be configured to be a DHCP Server, a DHCP Relay Agent, or both.
For more detailed information on N-Tron DHCP features, reference:
http://www.n-tron.com/tech_docs.php.
Under ‘White papers’, see. “Using DHCP to Minimize Equipment Setup Time”. Under ‘Installation Guides
and User Manuals’ see “DHCP Technical Instructions for 708 / 716/ 7018 / 7506 Series”.
(Revised 2014-03-31) Page 21 of 170
DHCP Client
The switch will automatically obtain an IP assignment from a DHCP Server, or optionally Fallback to a
configured IP assignment if unable to get an IP assignment from a DHCP server. Communication between
the client and server can optionally go through a DHCP Relay Agent.
DHCP Relay Agent
DHCP Relay Agent (Option 82) allows communication between the client and server to cross subnet and
VLAN boundries. It also allows for a device on a specific port to receive a specific IP address and if the
device is replaced, the replacement receives the same IP address as the original device.
DHCP Server
DHCP Server allows DHCP Client devices to automatically obtain an IP assignment. IP assignments can be
set up as a dynamic range of IP addresses available to any client device; or specific IP addresses based on
the clients MAC address, Client ID (Option 61), or Relay Agent connection (Option 82).
LLDP
Link Layer Discovery Protocol (LLDP) is a Layer 2 discovery protocol that allows devices attached to an
IEEE802 LAN to advertise to other devices the major capabilities they have and to store information they
discover in a MIB that can be accessed through SNMP. LLDP is formally described in IEEE Standard -
802.1AB.
Port Security—MAC Address Based
The Port Security feature restricts access to the switch by only accepting dynamically learned MAC
addresses and manually entered MAC addresses as authorized. Dynamically learned MAC addresses are
those that the switch detects on any port while in ‘Learning’ mode. A manually entered MAC address must
designate the ports that the address is authorized on. A non-authorized MAC address will be discarded and
will be shown on the intruder log. Locking can be selected or not port by port.
XML Settings Download
XML settings can be downloaded to a switch to achieve some switch configurations. XML settings cover a
subset of the settings available through the web browser. Reference Appendix A. XML Settings File Example
for the complete set of configurations that can be done using XML Settings Download. There are several top
level configuration sections and each of these sections is optional. Some sections have a ‘keep or delete’
choice such that one can load only those in the XML file deleting the pre-existing of those particular settings
or one can add the settings in the XML file to the already existing settings. The example also shows field
character limits, and provides other guidance.
Rate Limiting
Some systems generate a large amount of broadcast or multicast traffic occasionally. When it happens, the
entire network may experience failures that persist until there is manual intervention. One way to address
this problem is to control the broadcast or multicast traffic to remain below a user configured maximum
limit. The most effective limit may be best obtained in test. Thus the user is provided with the capability to
‘tune’ the limit by switch port. These are ingress filters. The percentage values are r epeatable to the purpose

and rise or fall as compared to each other, but are not meant to be as exact as in a piece of calibrated test
equipment.
