CNGE5MS

ENVIRONMENTALLY HARDENED MANAGED ETHERNET SWITCH
WITH (3) 10/100/1000BASE-TX & (2) 10/100/1000BASE-TX/FX
COMBO PORTS

v1.4 February 21, 2013

The ComNet™ CNGE5MS is a hardened, industrial five port all gigabit managed
Ethernet switch. It has three 10/100/1000Base-TX and two Gigabit combo ports
that utilize ComNet Small Form Factor (SFP) pluggable modules for the selection of
fiber and connector type and distance. The IEEE 802.3 compliant unit is a redundant
switch offering multiple Ethernet redundancy protocols, C-Ring, ComRing, C-RSTP
and MSTP/RSTP/STP. This redundancy feature protects your applications from network
interruptions or temporary malfunctions by redirecting transmission within the
network. The CNGE5MS offers centralized and convenient management through a
windows-based utility called eConsole. Redundant DC power inputs provide non-stop
operation in case of power supply disruption. The backup power input will take over
immediately when the primary DC power input fails. The unit provides relay outputs
that can be set up to indicate events and notify in case of potential problems.

Overview

Introduction

The CNGE5MS is a powerful, managed, hardened Ethernet switch that contains many features.
The switch will work under a wide variety of temperature, dirty and humid conditions. It can be
managed through WEB, TELNET, Consol or other third-party SNMP software. The CNGE5MS also
can be managed by a utility called eConsole.

eConsole is network management software that is very effective. With easy to use and intuitive
interface, you can easily configure multiple switches at the same time, and monitor the status of
those switches.

About Web-based Management

An embedded HTML web site resides in the flash memory on the CPU board. It contains
advanced management features and allows you to manage the switch from anywhere on the
network through a standard web browser such as Microsoft Internet Explorer.

The Web-Based Management function supports Internet Explorer 5.0 or later. It utilizes Java
Applets with an aim to reduce network bandwidth consumption, enhance access speed and
present an easy viewing screen.

Note: By default, IE5.0 or later version does not allow Java Applets to open sockets. You need to

explicitly modify the browser setting in order to enable Java Applets to use network ports.

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.

VLAN

A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, which allows
you to isolate network traffic. Only the members of the VLAN will receive traffic from the same
members of VLAN. Basically, creating a VLAN from a switch is logically equivalent of reconnecting
a group of network devices to another Layer 2 switch. However, all the network devices are still
plugged into the same switch physically.

The switch supports port-based and 802.1Q (tagged-based) VLAN. The default configuration of
VLAN operation mode is at 8 02.1Q .

VLAN Configuration – 802.1Q

Tagged-based VLAN is an IEEE 802.1Q specification standard, and it is possible to create a VLAN
across devices from different switch venders. IEEE 802.1Q VLAN uses a technique to insert a “tag”
into the Ethernet frames. Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers.

You can create Tag-based VLAN, and enable or disable GVRP protocol. There are 256 VLAN
groups to provide configure. Enable 802.1Q VLAN, the all ports on the switch belong to default
VLAN, VID is 1. The default VLAN cannot be deleted.

GVRP allows automatic VLAN configuration between the switch and nodes. If the switch is
connected to a device with GVRP enabled, you can send a GVRP request by using the VID of a
VLAN defined on the switch; the switch will automatically add that device to the existing VLAN.

global configuration command to

bridge protocol data units (BPDUs).

G Use the spanning-tree forward-time

global configuration command
to set the forwarding-time for the

The forwarding time determines
how long each of the listening and

I Use the spanning-tree cost interface

configuration command to set the
path cost for Spanning TreeProtocol
(STP) calculations. In the event of
a loop, spanning tree considers
the path cost when selecting
an interface to place into the
forwarding state.

I Use the spanning-tree port-priority

interface configuration command to
configure a port priority that is used
when two switches tie for position
as the root switch.

I Admin P2P of STP priority on this
