(24) 10/100/1000 BASE-TX + (4) 1000BASE-FX
with Power over Ethernet (PoE)
v1.4 Sept 2012
The ComNet™ CNGE28FX4TX24MSPOE+ Managed Redundant Ring Ethernet Switch
provides robust transmission of (24) 10/100/1000BASE-T(X) ports and (4) 1000BASEFX ports of Ethernet data. Fully compliant with IEEE 802.3at, up to 720 watts of PoE or
PoE+ power is available for distribution across all 24 Base-TX ports. The four 1000BASEFX ports may be used with multimode or single-mode optical fiber when used with
ComNet SFPs. The exclusive C-Ring protects mission-critical applications from network
interruptions or temporary malfunctions with its fast recovery technology. eConsole,
a powerful, easy-to-use Windows-based utility, allows the CNGE28FX4TX24MSPOE+
to be centrally managed. Diverse media selection provides for easy implementation
of point-to-point, linear add-drop, drop-and-repeat, star, or true self-healing ring and
mesh network system architectures. The electrical ports support the 10/100/1000Mbps
Ethernet IEEE802.3 protocol, and auto-negotiating and auto-MDI/MDIX features
are included for simplicity and ease of installation. These network-managed layer 2
switches are optically (1000BASE-FX) and electrically compatible with any IEEE802.3
compliant Ethernet device. Unlike most Ethernet switches, the environmentally
hardened CNGE28FX4TX24MSPOE+ is designed for direct deployment in difficult
out-of-plant or roadside operating environments. Featuring a low-profile 1-RU high
rack-mountable package, these units may be mounted within any standard 19-inch
rack cabinet, and the high-capacity power supply for operation of the switch and PoE
PSE (Power Sourcing Equipment) is completely self-contained.

Overview
Introduction
CNGE28FX4TX24MSPOE+ series is managed Redundant Ring Ethernet switch with 24
10/100/1000BASE-T(X) ports with PoE (PSE) function and 4x1000BASE-X SFP ports. With
completely support of Ethernet Redundancy protocol, C-Ring (recovery time < 30ms over 250
units of connection), Legacy Ring and MSTP/RSTP/STP (IEEE 802.1 s/w/D) can protect your
mission-critical applications from network interruptions or temporary malfunctions with its fast
recovery technology. ComNet switches provide advanced IP-based bandwidth management
that can limit the maximum bandwidth for each IP device. Users can configure IP cameras and
Network Video Recorders with more bandwidth and limit other device bandwidth. ComNet
switches also support application-based QoS (Quality-of-Service). Application-based QoS
can set highest priority for data stream according to the TCP/UDP port number. The ComNet
special IP police function can only permit allowed IP address with MAC address to access the
networking. Hacker cannot access the IP surveillance network without permission. It can avoid
hackers from stealing video privacy data and attacking IP camera, Network Video Recorders and
controllers. ComNet switches also provided advanced DOS/DDOS auto prevention. If there is
any IP flow become big in short time, ComNet switches will lock the source IP address for certain
amount of time to prevent the attack. Its hardware based prevention so it can prevent DOS/
DDOS attack immediately and completely. CNGE28FX4TX24MSPOE+ series also supports Power
over Ethernet, a system to transmit electrical power up to 30 watts, along with data, to remote
devices over standard CAT5/5-e/6 cable in an Ethernet network. Each CNGE28FX4TX24MSPOE+
series switch has 24 10/100/1000BASE-T(X) PSE (Power Sourcing Equipment) ports. PSE is a
device (switch or hub for instance) that will provide power in a PoE connection. All functions of
the CNGE28FX4TX24MSPOE+ series can be centrally managed by a powerful windows utility,
eConsole. These switches are one of the most reliable choices for highly managed and Gigabit
Fiber Optic Ethernet applications requiring PoE.

LLDP
LLDP Parameters
This page allows the user to inspect and configure the current LLDP port settings.
Label
Description
TX Interval
The switch is periodically transmitting LLDP frames to its neighbor’s
for having the network discovery information up-to-date. The interval
between each LLDP frame is determined by the TX Interval value.
Valid values are restricted to 5 - 32768 seconds.
TX Hold
Each LLDP frame contains information about how long the information
in the LLDP frame shall be considered valid. The LLDP information
valid period is set to TX Hold multiplied by TX Interval seconds. Valid
values are restricted to 2 - 10 times.
TX Delay
If some configuration is changed (e.g. the IP address) a new LLDP
frame is transmitted, but the time between the LLDP frames will
always be at least the value of TX Delay seconds. TX Delay cannot be
larger than 1/4 of the TX Interval value. Valid values are restricted to
1 - 8192 seconds.
TX Reinit
When a port is disabled, LLDP is disabled or the switch is rebooted
a LLDP shutdown frame is transmitted to the neighbComNet units,
signaling that the LLDP information isn’t valid anymore. TX Reinit
controls the amount of seconds between the shutdown frame and a
new LLDP initialization. Valid values are restricted to 1 - 10 seconds.

Rx Errors
The number of received LLDP frames containing some kind of error.
Frames DiscardedIf an LLDP frame is received on a port, and the switch’s internal table
has run full, the LLDP frame is counted and discarded. This situation is
known as “Too Many Neighbor’s” in the LLDP standard. LLDP frames
require a new entry in the table when the Chassis ID or Remote Port
ID is not already contained within the table. Entries are removed from
the table when a given port links down, an LLDP shutdown frame is
received, or when the entry ages out.
TLVs Discarded
Each LLDP frame can contain multiple pieces of information, known as
TLVs (TLV is short for “Type Length Value”). If a TLV is malformed, it is
counted and discarded.

Legacy Ring
Legacy ring provides support for the switch to be used in an existing ring of ComNet X-Ring
enabled switches.
X-Ring provides a faster redundant recovery than Spanning Tree topology. The action is similar
to STP or RSTP, but the algorithms between them are not the same. In the X-Ring topology, every
switch should be enabled with X-Ring or Legacy Ring function and two ports should be assigned
as the member ports in the ring. Only one switch in the X-Ring group would be set as the master
switch that one of its two member ports would be blocked, called backup port, and another port
is called working port. Other switches in the X-Ring group are called working switches and their
two member ports are called working ports. When the failure of network connection occurs,
the backup port of the master switch (Ring Master) will automatically become a working port to
recover from the failure.
The switch supports the function and interface for setting the switch as the ring master or not. The
ring master can negotiate and place command to other switches in the X-Ring group. If there are
2 or more switches in master mode, the software will select the switch with lowest MAC address
number as the ring master. The X-Ring master ring mode can be enabled by setting the Legacy
Ring configuration interface. Also, the user can identify whether the switch is the ring master by
checking the R.M. LED indicator on the front panel of the switch.

Restricted Role
If enabled, causes the port not to be selected as Root Port for the CIST or any MSTI,
even if it has the best spanning tree priority vector. Such a port will be selected as an
Alternate Port after the Root Port has been selected. If set, it can cause lack of spanning

because those bridges are not under the full control of the administrator. This feature is
also known as Root Guard.
Restricted TCN
If enabled, causes the port not to propagate received topology change notifications and
topology changes to other ports. If set it can cause temporary loss of connectivity after
changes in a spanning trees active topology as a result of persistent incorrectly learned
station location information. It is set by a network administrator to prevent bridges

Private VLAN
The Private VLAN membership configurations for the switch can be monitored and modified here.
Private VLANs can be added or deleted here. Port members of each Private VLAN can be added
or removed here. Private VLANs are based on the source port mask, and there are no connections
to VLANs. This means that VLAN IDs and Private VLAN IDs can be identical.
A port must be a member of both a VLAN and a Private VLAN to be able to forward packets. By
default, all ports are VLAN unaware and members of VLAN 1 and Private VLAN 1.
A VLAN unaware port can only be a member of one VLAN, but it can be a member of multiple
Private VLANs.

The classification is controlled by a QCL that is assigned to each port.
A QCL consists of an ordered list of up to 12 QCEs.
Each QCE can be used to classify certain frames to a specific QoS class.
This classification can be based on parameters such as VLAN ID, UDP/TCP port, IPv4/IPv6 DSCP or

Storm Control
Storm control for the switch is configured on this page.
There is a unicast storm rate control, multicast storm rate control, and a broadcast storm rate
control. These only affect flooded frames, i.e. frames with a (VLAN ID, DMAC) pair not present on
the MAC Address table.
The rate is 2^n, where n is equal to or less than 15, or “No Limit”. The unit of the rate can be
either PPS (packets per second) or KPPS (kilopackets per second). The configuration indicates the
permitted packet rate for unicast, multicast, or broadcast traffic across the switch.

Timeout
The Timeout, which can be set to a number between 3 and 3600
seconds, is the maximum time to wait for a reply from a server. If the
server does not reply within this timeframe, we will consider it to be
dead and continue with the next enabled server (if any).
RADIUS servers are using the UDP protocol, which is unreliable by
design. In order to cope with lost frames, the timeout interval is
divided into 3 subintervals of equal length. If a reply is not received
within the subinterval, the request is transmitted again. This algorithm
causes the RADIUS server to be queried up to 3 times before it is
considered to be dead.
Dead Time
The Dead Time, which can be set to a number between 0 and 3600
seconds, is the period during which the switch will not send new
requests to a server that has failed to respond to a previous request.
This will stop the switch from continually trying to contact a server that
it has already determined as dead.
Setting the Dead Time to a value greater than 0 (zero) will enable this
feature, but only if more than one server has been configured.

PoE Configuration - Reserved Power determined
There are three modes for configuring how the ports/PDs may reserve power.
Label
Description
Allocated mode In this mode the user allocates the amount of power that each port
may reserve. The allocated/reserved power for each port/PD is
specified in the Maximum Power fields.
Class mode
In this mode each port automatic determines how much power to
reserve according to the class the connected PD belongs to, and
reserves the power accordingly. Three different port classes exist and
one for 4, 7 and 15.4 Watts. (In this mode the Maximum Power fields
have no effect.)
LLDP-MED mode This mode is similar to the Class mode expect that each port
determine the amount power it reserves by exchanging PoE
information using the LLDP protocol and reserves power accordingly.
If no LLDP information is available for a port, the port will reserve
power using the class mode.( In this mode the Maximum Power fields
have no effect)
For all modes: If a port uses more power than the reserved power for the port, the port is shut
down.

Consumption
In this mode the ports are shut down when the actual power
consumption for all ports exceeds the amount of power that the
power supply can deliver or if the actual power consumption for a
given port exceeds the reserved power for that port. The ports are
shut down according to the ports priority. If two ports have the same
priority the port with the highest port number is shut down.
Reserved Power In this mode the ports are shut down when total reserved powered
exceeds the amount of power that the power supply can deliver. In
this mode the port power is not turned on if the PD requests more
power the available.
