INSTALLATION AND OPERATION MANUAL
CNGE8FX4TX4MS
ENVIRONMENTALLY HARDENED MANAGED
ETHERNET SWITCH WITH (4) 10/100/1000TX
+ (4) 100/1000FX SFP PORTS
V1.10 – July 2010
The ComNet™ CNGE8FX4TX4MS Managed Ethernet Switch provides
transmission of (4) 100/1000 BASE-TX and (4) 10/100/1000FX combo ports.
Unlike most Ethernet switches, these environmentally hardened units are
designed for deployment in difficult operating environments, and are available
for use with either conventional CAT-5e copper or optical transmission media.
Ports 1 – 4 support the 10/100/1000 Mbps Ethernet IEEE 802.3 protocol, and
auto-negotiating and auto-MDI/MDIX features are provided for simplicity and
ease of installation. Ports 5 – 8 are 10/100/1000 configurable for copper or
100/1000 fiber media for use with multimode or single mode optical fiber
without need for configuration, selected by optional SFP modules. These
network managed layer 2 switches are optically and electrically compatible
with any IEEE 802.3 compliant Ethernet devices. Plug-and-play design
ensures ease of installation, and no electrical or optical adjustments are ever
required. The CNGE8FX4TX4MS incorporates LED indicators for monitoring the
operating status of the managed switch and network.

  • Page 27: X-Ring Application

    X-Ring Application The switch supports the X-Ring protocol that can help the network recover from network connection failure within 20ms or less, and make the network system more reliable. The X-Ring algorithm is similar to Spanning Tree Protocol (STP) and Rapid STP (RSTP) algorithm but its recovery time is less than STP/RSTP.

  • Page 28: Coupling Ring Application

    Coupling Ring Application In the network, it may be necessary to have more than one X-Ring group. By using the coupling function it is possible to connect each X-Ring for a redundant backup. This will ensure the transmission between two ring groups will not fail. The following figure is an example of the coupling ring feature.

  • Page 29: Dual Homing Application

    Dual Homing Application The Dual Homing function is designed to prevent a connection loss between the X-Ring group and an upper level/core switch. By assigning two ports on the switches as Dual Homing ports, they will become the designated backup ports in the X-Ring group. The Dual Homing function only works when the X-Ring function is made active.

    VLAN configuration A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, that would allow 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 the logical equivalent of reconnecting a group of network devices to another Layer 2 switch.

  • Page 85: Vlan Configuration - Port-Based Vlan

    VLAN configuration - Port-based VLAN Packets can go among only members of the same VLAN group. Note all unselected ports are treated as belonging to another single VLAN. If the port-based VLAN is enabled, the VLAN-tagging is ignored. In order for an end station to send packets to different VLAN groups, it has to be either capable of tagging packets it sends with VLAN tags or attached to a VLAN-aware bridge that is capable of classifying and tagging the packet with different VLAN ID based on not only default PVID but also other information about the packet, such as the protocol.

    802.1Q VLAN A tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN across devices from different switch venders. An IEEE 802.1Q VLAN uses a technique to insert a ‘tag’ into the Ethernet frames. The tag contains a VLAN Identifier (VID) that indicates the VLAN numbers.

  • Page 90: Rapid Spanning Tree

    Rapid Spanning Tree Rapid Spanning Tree Protocol (RSTP) is an evolution of the Spanning Tree Protocol and provides for faster spanning tree convergence after a topology change. The system also supports STP and the system will auto detect the connected device that is running STP or RSTP protocol.

Edge: The port directly connected to the end stations cannot create a bridging loop in the network. To configure the port as an edge port, set the port to True status. Non STP: The port includes the STP mathematic calculation.

  • Page 93: Snmp Configuration

    SNMP Configuration Simple Network Management Protocol (SNMP) is the protocol developed to manage nodes (servers, workstations, routers, switches and hubs etc.) on an IP network. SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network growth. Network management systems learn of problems by receiving traps or change notices from network devices implementing SNMP.

  • Page 94: Trap Configuration

    SNMP System Configuration interface Trap Configuration A trap manager is a management station that receives traps – the system alerts generated by the switch. If no trap manager is defined, no traps will be issued. Create a trap manager by entering the IP address of the station and a community string.

    IGMP Configuration The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP) suite. The IP suite manages multicast traffic by using switches, routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect IGMP queries, report packets and manage IP multicast traffic through the switch.

  • Page 103: X-Ring

    X-Ring X-Ring provides a faster redundant recovery than Spanning Tree topology. The action is similar to STP or RSTP, but the algorithms not the same. In the X-Ring topology, every switch should enable the X-Ring function and assign two member ports in the ring. Only one switch in the X-Ring group would be set as a master switch that would be blocked, called the backup port, and another port is called the working port.

    LLDP Configuration Link Layer Discovery Protocol (LLDP) is defined in the IEEE 802.1AB, it is an emerging standard which provides a solution for the configuration issues caused by expanding LANs. LLDP specifically defines a standard method for Ethernet network devices such as switches, routers and wireless LAN access points to advertise information about themselves to other nodes on the network and store the information they discover.

  • Page 109: Mac Address Table

    MAC Address Table Use the MAC address table to ensure the port security. Static MAC Address You can add a static MAC address; it remains in the switch's address table, regardless of whether the device is physically connected to the switch. This saves the switch from having to re-learn a device's MAC address when the disconnected or powered-off device is active on the network again.
