(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.

LLDP Port Configuration
Label Description
Port The switch port number of the logical LLDP port.
Mode Select LLDP mode.
Rx only The switch will not send out LLDP information, but LLDP information from
neighbor units is analyzed.
TX only The switch will drop LLDP information received from neighbor’s, but will send
out LLDP information.
Disabled The switch will not send out LLDP information, and will drop LLDP information
received from neighbor’s.
Enabled The switch will send out LLDP information, and will analyze LLDP information
received from neighbor’s.
CDP Aware Select CDP awareness.
The CDP operation is restricted to decoding incoming CDP frames (The switch doesn’t
transmit CDP frames). CDP frames are only decoded if LLDP for the port is enabled.
Only CDP TLVs that can be mapped into a corresponding field in the LLDP neighbor’s
table are decoded. All other TLVs are discarded (Unrecognized CDP TLVs and discarded
CDP frame are not shown in the LLDP statistic. Only). CDP TLVs are mapped into LLDP
neighbor’s table as shown below.
CDP TLV “Device ID” is mapped into the LLDP “Chassis ID” field.
CDP TLV “Address” is mapped into the LLDP “Management Address” field. The CDP
address TLV can contain multiple addresses, but only the first address is shown in the
LLDP neighbor’s table.
CDP TLV “Port ID” is mapped into the LLDP “Port ID” field.
CDP TLV “Version and Platform” is mapped into the LLDP “System Description” field.
Both the CDP and LLDP supports “system capabilities”, but the CDP capabilities cover
capabilities that are not part of the LLDP. These capabilities are shown as “others” in the
LLDP neighbor’s table.
If all ports have CDP awareness disabled the switch forwards CDP frames received from
neighbor devices. If at least one port has CDP awareness enabled all CDP frames are
terminated by the switch.
Note: When CDP awareness for a port is disabled the CDP information isn’t removed
immediately, but will be removed when the hold time is exceeded.
Port Descr Optional TLV: When checked the “port description” is included in LLDP information
transmitted.
Sys Name Optional TLV: When checked the “system name” is included in LLDP information
transmitted.
Sys Descr Optional TLV: When checked the “system description” is included in LLDP information

LLDP Neighbor Information
This page provides a status overview for all LLDP neighbors. The displayed table contains a row
for each port on which an LLDP neighbor is detected. The columns hold the following information:
Label Description
Local Port The port on which the LLDP frame was received.
Chassis ID The Chassis ID is the identification of the neighbor’s LLDP frames.
Remote Port ID The Remote Port ID is the identification of the neighbor port.
System Name System Name is the name advertised by the neighbor unit.
Port Description Port Description is the port description advertised by the neighbor
unit.
System
Capabilites
System Capabilities describes the neighbor unit’s capabilities. The
possible capabilities are:
1. Other
2. Repeater
3. Bridge
4. WLAN Access Point
5. Router
6. Telephone
7. DOCSIS cable device
8. Station only
9. Reserved
When a capability is enabled, the capability is followed by (+). If the
capability is disabled, the capability is followed by (-).
Management
Address
Management Address is the neighbor unit’s address that is used
for higher layer entities to assist the discovery by the network
management. This could for instance hold the neighbor’s IP address.

LLDP Statistics
This page provides an overview of all LLDP traffic.
Two types of counters are shown. Global counters are counters that refer to the whole stack,
switch, while local counters refer to counters for the currently selected switch.

Local Counters
Label Description
Local Port The port on which LLDP frames are received or transmitted.
TX Frames The number of LLDP frames transmitted on the port.
Rx Frames The number of LLDP frames received on the port.
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.
TLVs
The number of well-formed TLVs, but with an unknown type value.
Unrecognized
Org. Discarded The number of organizationally TLVs received.
Age-Outs Each LLDP frame contains information about how long time the LLDP
information is valid (age-out time). If no new LLDP frame is received
within the age out time, the LLDP information is removed, and the
Age-Out counter is incremented.

Clear Clears the local counters. All counters (including global counters) are
cleared upon reboot.

Port This is the logical port number for this row.
Link The current link state is displayed graphically. Green indicates the link
is up and red that it is down.
Current Link
Provides the current link speed of the port.
Speed
Configured Link
Speed
Select any available link speed for the given switch port.
Auto Speed selects the highest speed that is compatible with a link
partner.
Disabled disables the switch port operation.
Flow Control When Auto Speed is selected for a port, this section indicates the flow
control capability that is advertised to the link partner.
When a fixed-speed setting is selected, that is what is used. The
Current Rx column indicates whether pause frames on the port are
obeyed, and the Current TX column indicates whether pause frames
on the port are transmitted. The Rx and TX settings are determined
by the result of the last Auto-Negotiation.
Check the configured column to use flow control. This setting is
related to the setting for Configured Link Speed.
Maximum Frame Enter the maximum frame size allowed for the switch port, including
FCS. The allowed range is 1518 bytes to 9600 bytes.
Excessive
Collision Mode
Configure port transmit collision behavior.
Discard: Discard frame after 16 collisions (default).
Restart: Restart back-off algorithm after 16 collisions.
Power Control The Usage column shows the current percentage of the power
consumption per port. The Configured column allows for changing
the power savings mode parameters per port.
Disabled: All power savings mechanisms disabled.
