(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.

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 |
|

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 |
System Capabilities describes the neighbor unit’s capabilities. The |
Capabilites |
possible capabilities are: |
|
1. Other |
|
2. Repeater |
|
3. Bridge |

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. |
