TRAFFIC DETECTOR RACK INDUSTRIALLY HARDENED MANAGED SWITCH WITH (8) 10/100/1000BASE-TX & (4) 100/1000BASE-FX PORTS & OPTIONAL POE+

This manual serves the following ComNet Model Numbers:

CNGE12FX4TX8MS/TS

CNGE12FX4TX8MSPOE/TS

The ComNet CNGE12FX4TX8MS[POE]/TS is a twelve port, managed Ethernet switch. The switch is mechanically designed to fit into the input file of a NEMA TS2 traffic detector rack and derives power and ground from the backplane. The small form factor allows the user to take advantage of existing rack space already dedicated within an already space limited traffic cabinet making installation clean and easy. The four SFP ports are 100/1000Mbps capable, allowing single-mode or multimode optical fiber transmission with the use of optional SFPs. The density of the SFP ports allows for an optical drop-and-repeat, ring or star (north-south-east-west) topology to address the majority of traffic applications. The remaining eight RJ-45 ports allow for highthroughput 10/100/1000TX Gigabit connectivity on the local copper Ethernet access ports. The CNGE12FX4TX8MSPOE/TS features IEEE 802.3at (30W) PoE on all eight RJ-45 Ethernet ports for PoE-compliant devices such as wireless radios or IP cameras. The ideal solution when footprint within the traffic cabinet is limited.

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 Discarded

If 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 Neighbors” 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 incremental.

Indicates the DHCP relay information mode option operation. The option 82 circuit ID format as “[vlan_id][module_id][port_no]”. The first four characters represent the VLAN ID, the fifth and sixth characters are the module ID(in standalone device it always equal 0, in stackable device it means switch ID). ), and the last two characters are the port number. For example, “00030108” means the DHCP message receive form VLAN ID 3, switch ID 1, port No 8. And the option 82 remote ID value is equal the switch MAC address. Possible modes are: Enabled: Enable DHCP relay information mode operation. When DHCP relay information mode operation is enabled, the agent inserts specific information (option

82) into a DHCP message when forwarding to DHCP server and removes it from a DHCP message when transferring to DHCP client. It only works when DHCP relay operation mode is enabled. Disabled: Disable DHCP relay information mode operation.

Indicates the DHCP relay information option policy. When DHCP relay information mode operation is enabled, if agent receives a DHCP message that already contains relay agent information it will enforce the policy. The ‘Replace’ option is invalid when relay information mode is disabled. Possible policies are: Replace: Replace the original relay information when a DHCP message that already contains it is received. Keep: Keep the original relay information when a DHCP message that already contains it is received. Drop: Drop the package when a DHCP message that already contains relay information is received.

Port Setting

Port Control

This page displays current port configurations. Ports can also be configured here.

Label Description

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

Selects any available link speed for the given switch port. Only speeds supported by the specific port is shown. Possible speeds are: Disabled – Disables the switch port operation. Auto – Cu port auto negotiating speed with the link partner and selects the highest speed that is compatible with the link partner.

10Mbps HDX – Force the Cu port to 10Mbps half duplex mode. 10Mbps FDX – Force the Cu port to 10Mbps full duplex mode. 100Mbps HDX – Force the Cu port to 100Mbps half duplex mode. 100Mbps FDX – Force the Cu port to 100Mbps full duplex mode. 1Gbps FDX – Force the Cu port to 1Gbps full duplex mode.

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.
