Ethernet Switching Technology

Ethernet Switching Technology dramatically boosted the total bandwidth of a network, eliminated congestion problems inherent with CSMA/CD (Carrier Sense multiple access with Collision Detection) protocol, and greatly reduced unnecessary transmissions.

This revolutionized networking. First, by allowing two-way, simultaneous transmissions over the same port (Full-duplex), which essentially doubled the bandwidth. Second, by reducing the collision domain to a single switch-port, which eliminated the need for carrier sensing. Third, by using the store-and-forward technology’s approach of inspecting each packet to intercept corrupt or redundant data, switching eliminated unnecessary transmission that slow the network. By employing address learning, which replaced the inefficient receiving port.

Auto-negotiation regulates the speed and duplex of each port, based on the capability of both devices. Flow-control allows transmission from a 100Mbps node to a 10Mbps node without loss of data. Auto-negotiation and flow-control may require disablement for some networking operations involves legacy equipment. Disabling the auto-negotiation is accomplished by fixing the speed or duplex of a port.

Ethernet Switching Technology supplied higher performance at costs lower than other solutions. Wider bandwidth, no congestion, and the reduction in traffic is why switching is replacing expensive routers and inefficient hubs as the ultimate networking solution. Switching brought a whole new way of thinking to networking.

2. Hardware Description

This Section mainly describes the hardware of the GSW-2493, and gives a physical and functional overview of the switch.

Physical Dimension

The GSW-2493 physical dimension is

440mm(W) x 280mm(D) x 44mm(H)

Front Panel

The Front Panel of the GSW-2493 consists of 3 module slots. One module slot is located in rear-panel of the switch.

LED Indicators

The LED Indicators gives real-time information of systematic operation status. The LED indicators are located in every module. The LED indicators will be different for different module. The following table provides descriptions of LED status and their meaning.

Off In half-duplex mode

Table 2-1. The Description of LED Indicators

Rear Panel

One module slot, 3-pronged power plug, 2 fans, power switching, and one console port is located at the rear Panel of the GSW-2493 as shown in Figure 2-1. The Switch will work with AC power in the range of 100-240V AC, 50-60Hz.

Figure 2-1. The Rear Panel of the GSW-2493

Desktop Installation

Set the Switch on a sufficiently large flat space with a power outlet nearby. The surface where you put your Switch should be clean, smooth, level and sturdy. Make sure there is enough clearance around the Switch to allow attachment of cables, power cord and allow air circulation.

Attaching Rubber Feet

A. Make sure mounting surface on the bottom of the Switch is grease and dust free. B. Remove adhesive backing from your Rubber Feet. C. Apply the Rubber Feet to each corner on the bottom of the Switch. These footpads

can prevent the Switch from shock/vibration.

Rack-mounted Installation

The GSW-2493 come with a rack-mounted kit and can be mounted in an EIA standard size, 19-inch Rack. The Switch can be placed in a wiring closet with other equipment.

Perform the following steps to rack mount the switch:

A. Position one bracket to align with the holes on one side of the switch and secure it

with the smaller bracket screws. Then attach the remaining bracket to the other

side of the Switch. B. After attached both mounting brackets, position the switch in the rack by lining up

the holes in the brackets with the appropriate holes on the rack. Secure the Switch

to the rack with a screwdriver and the rack-mounting screws.

Note:

the front and 3.4 inches (8 cm) on the back of the Switch. This is especially

important for enclosed rack installation.

For proper ventilation, allow about at least 4 inches (10 cm) of clearance on

Power On

Connect the power cord to the power socket on the rear panel of the Switch. The other side of power cord connects to the power outlet. The internal power supply of the Switch works with voltage range of AC in the 100-240VAC, frequency 50~60Hz. Check the power indicator on the front panel to see if power is properly supplied.

3. Network Application

GSW-2493 is designed as a segment switch. That is, with its large address table (8000 MAC address) and high performance, it is ideal for interconnecting networking segments.

PC, workstations, and servers can communicate each other by directly connecting with GSW-2493. The switch automatically learns nodes address, which are subsequently used to filter and forward all traffic based on the destination address.

By using Gigabit, Gigabit Fiber, or Ethernet Fiber port, the Switch can connect with another switch or hub to interconnect other small-switched workgroups to form a larger switched network. Meanwhile, you can also use Ethernet or Gigabit fiber ports to connect switches.

Stacking Workgroup

With stackable technology can unites up to eight individual stackable switches into a single logical unit, using cables and with stacking software supported. The stack behaves as a single switching unit that is managed by a master switch elected from one of the member switches. The master switch automatically creates and updates all the switching tables. A working stack can accept new members or delete old ones without service interruption

Each switch in the stack has the capability to behave as a master or subordinate in the hierarchy. The master switch is elected and serves as the control center for the stack. The subordinates act as forwarding processors. Each switch is assigned to a one workgroup ID. Up to eight separate switches can be joined together as a workgroup. The stack can have switches added and removed without affecting stack performance.

There are no special tools, extra software, or expensive equipment needed to form a Stacking workgroup. It provides single image management for entire Stack (fewer

devices to manage); management applications represent the Stack as a single device, and simple point and click management. Stackable technology allows you to increase the resiliency and the versatility of your network edge to accommodate evolution for speed and converged applications. Following figures are example of stacking workgroup application.

Connecting to the Switch

The Console port is a female DB-9 connector that enables a connection to a PC or terminal for monitoring and configuring the Switch. Use the supplied RS-232 cable with a male DB-9 connector to connect a terminal or PC to the Console port.

The Console configuration (out of band) allows you to set Switch for remote terminal as if the console terminal were directly connected to it.

4. Console Management

When the connection between Switch and PC is ready, turn on the PC and run a terminal emulation program or

IGMP Theory of Operation

The following three topologies detail how IGMP Query works and to be configured

within a network:

1. Auto mode needs to be enabled when the router’s IP address is smaller than

2. IGMP needs to be enabled when the router’s IP address is not smaller than other switches in the subnet. This Router supports IGMP protocol, but

other switches in the subnet.

IGMP has to be enabled, and the Router has to be the Querier.

3. The following topology must be set when the IP address of the switch is not the smallest in the subnet. The network will cause a multi-cast storm from the IGMP client report if it is in Auto mode. All switches must be in disable mode when the VOD server is configured for IGMP Querier.

Note:

It is suggested that the VOD server switch have the smallest IP address.

VLAN configuration

A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic so only members of the VLAN receive traffic from the same VLAN members. 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 plug into the same switch physically.

The switch supports port-based, 802.1Q (tagged-based) and protocol-base VLAN in web management page. In the default configuration, VLAN support is “disable”.

VLAN Configuration interface

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 enabled, the VLAN-tagging is ignored.

If an end station sends packets to different VLANs, 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

Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, 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 can’t be deleting.

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 using the VID of a VLAN defined on the switch; the switch will automatically add that device to the existing VLAN.

Spanning Tree

The Spanning-Tree Protocol (STP) is a standardized method (IEEE 802.1d) for avoiding loops in switched networks. When STP enabled, to ensure that only one path at a time is active between any two nodes on the network. We are recommended that you enable STP on all switches ensures a single active path on the network.

Port Mirroring

The Port mirroring is a method for monitor traffic in switched networks. Traffic through ports can be monitored by one specific port. That is, traffic goes in or out monitored ports will be duplicated into mirror port.

Port Mirroring State:

set mirror mode: Disable, RX, TX, and Both.

Analysis Port:

It’s mean mirror port can be used to see all monitor port traffic.

You can connect mirror port to LAN analyzer or Netxray.

Monitor Port:
