Overview of Advanced Features
1.2.1
Mode of Operation
Each port on the switch can be configured into different modes of operation as shown below:
Copper Ports:
•
Half Duplex
•
Full Duplex
•
Auto Negotiation
1000Base Copper or any Fiber Ports:
•
Full Duplex
Half Duplex
In half duplex mode, the CSMA/CD media access method is the means by which two or more ports share a
common transmission medium. To transmit, a port waits (defers) for a quiet period on the medium (that is, no other
port is transmitting) and then sends the intended message in bit-serial form. If, after initiating a transmission, the
message collides with that of another port, then each transmitting port intentionally transmits for an additional
predefined period to ensure propagation of the collision throughout the system. The port 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 ports 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.
However, a receiving endpoint may request that the transmitting endpoint pause transmission to prevent receive
buffer overflow. When the receiving buffer capacity becomes sufficient again, the receiving endpoint will notify the
transmitting endpoint that transmission may resume.
Auto Negotiation
In Auto Negotiation mode, the port/hardware detects the mode of operation of the port that is connected to it and
sets its mode to match the mode of the station.
1.2.2
Port Mirroring
A Mirroring Port is a dedicated port that is configured to receive copies of Ethernet frames that are being sent or
received from a monitored port. This is normally only used during problem shooting and debug of the network.
Under normal operation Port Mirroring is disabled.
1.2.3
Port Trunking
Port Trunking is the ability to group 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.

FEATURES AND SPECIFICATIONS
OVERVIEW OF ADVANCED FEATURES
Quality of Service (QoS)
Quality of service (QoS) refers to resource reservation control mechanisms. Quality of service is the ability to
provide different priorities to different applications, users, or data flows. QoS guarantees are important if the
network capacity is insufficient, especially for real-time streaming multimedia applications 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.
The QoS of an egressing frame can be set based on the three QoS mechanisms listed below:
1. IEEE 802.1p (Tagged QOS)
2. DSCP (differentiated services code points) (RFC 2474)
3. Port (Default Priority)
1.2.5
Virtual LAN (VLAN)
The switch provides support for setting up tagged Virtual Local Area Networks (VLANs). A port may belong to any
number of VLANs. The VLAN membership of an end 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, so if a port is not a member of any other VLAN, it will default back to VLAN
1.This allows the switch to operate as a 'normal' switch when it is used in a network. A port may be automatically
removed from the Default VLAN when it is reconfigured to belong to another Virtual LAN. By default, the switch will
automatically remove a port from the default VLAN when it is reconfigured to another Virtual LAN. See the VLAN
configuration section in Chapter 2 for additional information.
If switch ports are configured to transmit and receive untagged frames, then 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 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 NT24k switch also has 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: RSTP is only supported on one VLAN.

REVISED 2016-08-30
DRAWING NO. LP0991
Rapid Spanning Tree Protocol (RSTP)
The Rapid Spanning Tree Protocol as specified in IEEE 802.1D-2004 is supported. One Spanning Tree on one
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 establishes 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 the rapid transition of ports to the forwarding state. STP transmits BPDUs (bridge
protocol data units) from only the root bridge. RSTP transmits BPDUs from every bridge. RSTP inter-operates with
older STP switches by falling back to STP when the older BPDUs are detected on bridge ports. The user can also
manually configure bridge ports to use STP when desired.
1.2.7
SNMP Traps
The NT24k Series switch supports SNMP Trap Stations to which SNMP Traps will be sent. Four standard SNMP
traps are supported: Link Status (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.
1.2.8
IGMP Snooping
IGMP Snooping is enabled by default. The switch provides automatic (Plug and Play) IGMP configuration. IGMP
snooping provides intelligent network support for multicast applications, reducing unneeded network traffic. 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.
The Internet Group Management Protocol (IGMP) is a protocol that provides a way for a device to report its
multicast group membership to adjacent 'routers'. In this case NT24k 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 NT24k series supports v1 and v2.
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.
1.2.9
N-Link™
The purpose of N-Link™ is to provide a way to redundantly couple an N-Ring topology to another topology,
typically another N-Ring topology. Each N-Link configuration requires 4 switches, two on each network.On the NRing network, one switch will be the N-Link Master and an adjacent switch will be the N-Link Slave. On the
connected network, one switch will be the N-Link Primary Coupler and another switch will be the 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.

FEATURES AND SPECIFICATIONS
OVERVIEW OF ADVANCED FEATURES
N-Ring™
N-Ring™is designed for easy setup. Switches are configured for N-Ring membership by default. Setting a switch
as the N-Ring manager is the only required step for enabling the ring as long as preset ports are used to connect
ring members. Subsequently, N-Ring operates dynamically upon each power up. 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.
1.2.11
CIP™
The CIP™ (Common Industrial Protocol) feature allows N-Tron Series 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 trigger 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 created EDS and ICO files are provided with the NT24k switch series.
Note: Information about using CIP with the NT24k can be found in the CIP User Manual & Installation Guide
and the CIP Installation Kit for the NT24k switch family.
1.2.12
PPP
Point to Point Protocol (PPP) allows a browser like interface over the CLI port.
1.2.13
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. The DHCP Client is enabled by default, with 192.168.1.201 as the
default fallback address.
1.2.14
Event Logging
The switch may be configured to log certain system events as they occur. Event Logging is disabled by default but
is easily enabled through the Web browser.
These events include:
•
system startup and shutdown
•
port link up or link down changes
•
logon and logout from the Web or
Console
•
N-Ring status changes
•
ports becoming enabled or disabled
The most recent log information is visible via the web interface and the complete log file may be exported for
external analysis.

RFilter Ports
From the RFilter (Router Multicast Data Filter) option, the user can choose whether or not data frames with known
group multicast addresses are sent to the router ports. Control packets will be sent to the router(s) regardless of
this setting.
Known group multicast addresses are learned from dynamic IGMP Snooping operations. If IGMP is enabled and a
port is a router port, then having RFilter enabled will stop IGMP group data from egressing on the port unless a join
to that specific IGMP group has come into the port. IGMP controls (Join, Leave, Query) are still sent.
The Router Multicast Data Filter is enabled for all ports by default. Router ports do not get data frames with known
multicast destination addresses unless a join for that specific multicast address has been received on that port.
Join overrides an RFilter.
If RFilter is disabled, the router ports get data frames with known multicast destination addresses.
RFilter can be set for individual ports: any, all or none. For each port, RFilter will have an impact only if that port is
manually or dynamically chosen as a router port.

5. Connect the Control Link cable. Ensure that the Slave switch status now shows a state of “Slave”.
6. Connect the Coupler Link cables.
7. Check N-Link status on the Master by selecting the N-Link Status View page.
Configuration Requirements:
•
The Master and Slave must be part of the N-Ring topology.
•
If using default configuration choices, the administrator only needs to configure the N-Link Master. The
N-Link Slave and both Coupler switches will auto-detect any needed configuration.
•
If not using default configuration choices, the administrator may also need to configure the Default Coupler
port on the N-Link Slave.
•
There must be a direct link between the Master and Slave Control ports. Use of media converters or other
switches is not supported.
•
There must be a direct link between the Master and Slave Partner ports. Use of media converters or other
switches is not supported.
•
There must be an N-Link aware switch on each side of the Master.
•
N-Link will only support a single point of failure. Multiple points of failure and misconfiguration are not
supported and may cause a network storm under some circumstances.
•
Control and Partner connections should be either fiber or 10/100Base-TX copper.
•
•
The use of copper SFP transceivers for N-Link control and partner connections is not recommended
due to the variances of link performance between SFP manufacturers.
•
Per the IEEE 802.3 standard (Clause 40), a 1000Base-T PHY is required to wait 350-750 milliseconds
before reporting a link down condition; and is therefore unsuitable for use as an N-Link control or
partner connection.
For optimal performance:
•
The speed of the Partner segment must match the speed of the other N-Ring segments. Therefore, the
Partner connection must be 1 gigabit fiber when the other N-Ring segments have a 1 gigabit speed.
•
When using a 700/7000 Series N-Link Slave, the control port should use a fiber connection.

2. Do not create redundant links unless either RSTP or N-Ring is enabled.
3. The Default VLAN and any active N-Ring VLAN cannot be deleted.
4. RSTP and N-Ring are different modes and cannot share links or segments. If a port is both an RSTP port
and an active N-Ring port, then RSTP will be disabled for that port. Other ports may have RSTP enabled.
5. Do not connect the N-Ring to actively Trunking ports on an Auto Member or Multi Member configured
switch.
6. An NT24k® switch can only participate in one N-Ring unless in Multi Member mode.
7. Since VLANs are implemented for security reasons as well as traffic flow, N-Ring only makes minimal
VLAN changes. It is up to the administrator to ensure that VLANs are configured correctly on the N-Ring
manager and all N-Ring members.
8. For optimal performance, all N-Ring segments must be configured for the same speed.
Warning: To prevent a network storm, multiple segments between N-Ring members on one or more N-Rings
must not occur. N-Ring members should only be connected to each other by the N-Ring ports.

PoE
PoE (Power Over Ethernet) is an internal hardware capability that outputs power and data on Ethernet cabling to
Powered Devices (PDs) such as VoIP phones, IP camera, and industrial devices. PoE eliminates the need to run
separate data and power cables between the PSE (PoE Source Equipment) and the PoE powered device.
PoE Management on the NT24k provides the ability to set the PoE power budget, enable/disable PoE on specific
ports, and set power limits per port.
Note: PoE is only supported on certain NT24k switches.

IEEE 802.1x MIB
The IEEE 802.1x MIB, IEEE 8021-PAE-MIB, is supported by the NT24k®. Since the NT24k does not support the
supplicant features of 802.1x, the MIB tables pertaining to the supplicant behavior will not be populated and will be
blank when queried.
With this release, the IEEE 802.1x MIB support is limited. Ports are only tracked when an 802.1x aware supplicant
is attached. This means that not all 802.1x enabled ports will be visible, only those with valid supplicants. The
statistics available through the MIB only pertain to the device since it either passed or failed authentication. Once
the link goes down on the port, the statistics will be reset. Furthermore, any configuration items accessed through
the IEEE 802.1x MIB can be set to modify the behavior of the port, but these changes will not persist across link
events or power cycles.
Configuration changes that occur through the NT24k MIB will be persisted across link events and power cycles.
Support for persisted statistics and configuration settings in the IEEE 802.1x MIB will be added to the NT24k in a
future release.
The IEEE 802.1x MIB allows for the writing to dot1xPaeSystemAuthControl. This is not supported in the current
release of the NT24k firmware. dot1xPaeSystemAuthControl is considered a read-only attribute. The functionality
for this is located in the NT24k MIB as ntronSecurityDot1xConfigStatus.
The IEEE 802.1x MIB allows for the writing to dot1xAuthAdminControlledDirections. Controlling the direction of the
port traffic is not currently supported in the NT24k firmware and writing to dot1xAuthAdminControlledDirections will
not have an effect on the system.

COMMAND LINE INTERFACE
Appendix A
REVISED 2016-08-30
DRAWING NO. LP0991
Command Line Interface
The Command Line Interface (CLI) can be accessed by connecting a host device to the USB connector on the
switch. Once connected, the switch will appear as a serial connection. A standard terminal application may be
used to communicate to the switch through the serial connection. For serial port settings, see the “USB INTERFACE” section of the NT24K® Series Hardware Manual.
A second method to connect to the CLI is by way of TELNET. Using any standard TELNET client simply enter the
IP address of the switch to start a connection to the CLI.
The CLI contains some status and configuration capability. To interact with the CLI, a login is required. The default
username and password is 'admin'. Once logged in, a listing of available commands can be obtained through the
help interface. This is accessible by typing either “?” or “help?”. The following commands are available:

<upperThreshold>
- An integer from
-60 to 120.
The highest temperature for the switch without causing a fault to occur.
The threshold is specified as an integer in C degrees. The range is from
-60 C to 120 C, and the default is product dependent (shown only on
switches with temperature sensors).
admin system set lower
Threshold
<lowerThreshold>
- An integer from
-60 to 120.
The lowest temperature for the switch without causing a fault to occur.
The threshold is specified as an integer in C degrees. The range is from

WORKING WITH CONFIGURATION FILES
Appendix B
REVISED 2016-08-30
DRAWING NO. LP0991
Working with Configuration Files
Importing a Subset of an XML Configuration File
The XML configuration file may be used to set all of the configurable parameters on a NT24K switch or to configure
a subset of parameters. Setting common parameters across multiple switches can be easily accomplished by
creating and importing an abridged configuration file for this purpose.
Appendix C contains a complete list of XML configurable parameters. A simple way to start an XML configuration
file is to export the existing saved configuration file from the switch and modifying it to meet your new configuration
needs.
When creating a configuration file for a subset of available parameters, setting the system configuration mode to
Keep will maintain the current settings for all parameters other than those explicitly set by the new file being
imported. If the system configuration mode is not set to Keep, all parameters other than those being set by the
configuration file, will be reset to their default setting.
In the example below, the mode is set to Keep so that other switch settings are not reset to defaults. Additional
information about the content of the configuration file can be found at the top of any exported configuration file.
Using Port Numbers Instead of Port Names
In a configuration file, it is valid to use port numbers instead of names to simplify the sharing of configuration
settings. Ports are numbered starting at 1.
Port names may differ between switch models. For example, the NT24k-DR24 uses A1-A8, B1-B8, and C1-C8 and
the NT24k-14FX6 uses P1-P8 and FX1-FX6. However the configuration files can reference ports 1-24 for an
NT24k and ports 1-14 for an NT24k-14FX6.
In the following example, VLAN 1 is configured for ports 1 through 8 and VLAN 2 is configured for ports 9 through
16. This settings file can be imported into any NT24k® switch that supports 16 or more ports. Note that the
configuration file must also set the appropriate port PVIDs.

APPENDIX B
WORKING WITH CONFIGURATION FILES
Importing an Incompatible XML Configuration File
Errors related to invalid port names or numbers may occur when importing a configuration file from one model of
an NT24k switch into a different model of an NT24k switch.
Resolving Invalid Port Mappings
If the number of ports in the XML configuration file is greater than on the target model, then the following sections
should be removed for each of the extra ports.
•
SystemConfiguration/PoeMgmtGroup/PoeMgmtConfig/PoePorts/Port (PoE models only)
•
SystemConfiguration/PortGroup/PortConfig/Ports/Port
•
SystemConfiguration/RateLimitGroup/RateLimitConfig/RateLimits/Limit
•
SystemConfiguration/RstpGroup/RstpConfig/RstpPorts/Port
Notice that if the target switch has additional ports whose settings are not specified in the imported configuration
file, then these additional ports will have their settings set to default values if the mode has not been set to “Keep”.

APPENDIX B
WORKING WITH CONFIGURATION FILES
REVISED 2016-08-30
DRAWING NO. LP0991
Ports on the target switch that do not exist in the configuration file will be added to Default VLAN 1. If the
configuration file has extra VLANs with ports that do not exist, an error will be generated for each non-existent port.
Resolving Invalid Port Names
If the port names in the XML configuration file are different than on the target model, then rename the ports for the
following sections so that the new names correspond to the intended ports on the target model.
•
SystemConfiguration/MirrorGroup/MirrorConfig/Destination
•
SystemConfiguration/NLinkGroup/NLinkConfig/ControlPort

have their ports renamed.
