Introduction

16× 10/100Mbps ports Fast Ethernet Switch with Per-port VLAN

function

Live-FSH16T+ Fast Ethernet Switch is an auto-sensing and auto-negotiating 10/100ABSE-TX

Fast Ethernet Switch with VLAN and Priority capability. Its sixteen 10/100Mbps station ports

provide 10/100Mbps connections to Ethernet/Fast Ethernet network.

Live-FSH16T+’s unique switching fabric provides full wire speed for all ports. With auto-sensing,

Live-FSH16T+ automatically detects the speed of the devices you plug into, and routes the

incoming data to its destination. Its auto-negotiating function allows existing devices running at

different speeds to communicate easily within the same network.

Live-FSH16T+ also supports VLAN and Priority functions as briefly described in the following

sections:

Port-based VLAN for Instant Connectivity and Workgroup

Privacy

VLAN ensures instant connectivity and workgroup privacy. Since each station port can be

configured to whichever VLAN group, it offers utmost flexibility for workgroup assignment as to

ensure workgroup privacy. For those ports that join a VLAN, it offers instant connectivity without

further configuration efforts from network administrator. Members of a same VLAN group will be

included within a same broadcast domain, and will feel exactly as they are on the same network

segment (though they might not belong to the same physical network segment).

Per-port VLAN Configuration via a selection switch

With a selection switch in the back panel, user can set the switch in operate in either 14 or

15-VLANs mode. In “14-VLANs mode”, every port is in its own VLAN group sharing Port 1 and

Port 2. In “15-VLANs mode”, every port is in its own VLAN group sharing Port 2.

Store-and-Forward Architecture against Packet Loss

When network is under heavy traffic, the shared memory buffer in the switching devices might yield

incorrect detections due to overfed memory buffer. This setback can happen either when data is

transmitted in IEEE802.3x Full Duplex or Back Pressure Flow Control mode. To solve this problem,

Live-FSH16T+ utilizes a fixed memory buffer allocation with Store-and-forward transmission to

ensure an effective buffer allocation for each port.

Store-and-forward transmission controls data flow from transmitting to receiving nodes with the

receiving buffer threshold adjusted to an optimal value, thus guaranteeing against all possible packet

losses.

Live-FSH16T+ Fast Ethernet Switch User’s Manual V2.1

1 Product Overview

Active Flow Control

Live-FSH16T+ Fast Ethernet Switch implements in full duplex mode a flow control that is

compliant with the IEEE 802.3x standard. While in half duplex mode, it employs an optional Back

Pressure Flow Control to stall the incoming data when port buffers are saturated. With this flow

control mechanism, it can be ensured that frames dropped during transmission are reduced to a

minimum.

Full Wire Speed

Live-FSH16T+’s Full Wire Speed feature provides high-end performance for departmental and

workgroup environments at a fraction of the cost of similar devices. Typically, this feature was

found only in high-end switches designed to handle huge corporate networks. With bandwidth needs

and network efficiency concerns, Live-FSH16T+’s switching fabric design is the perfect answer for

bandwidth enhancement solution.

System/Port Status Information at a Glance

There are 2 sets of LEDs on the front panel: System LEDs and Station Port LEDs.

The System LEDs consist of the Power, VLAN1, and VLAN2 LEDs. Power LED shows Power

On/Off status of the switch. The VLAN1(15-VLANs) and VLAN2(14-VLANs) show the VLAN

configuration status

The Station Port LEDs reveal the link status, half/full duplex transmission, 10/100Mbps speed

mode and the collision status of each station port.

For detailed LED information, refer to Chapter 5, LED Indicators.

What is VLAN?

Defining VLAN

What is VLAN? Since VLAN solutions and implementations are still very vendor-specific, to define

precisely what VLANs will certainly arouse controversy. Nevertheless, most would agree that a

VLAN can roughly be equated as a broadcast domain. More specifically, VLANs can be seen as a

group of end stations, perhaps on multiple physical LAN segments, which are not constrained by

their physical location and can communicate as if they were on a common LAN.

There are several ways to define VLAN membership: port grouping, frame tagging, MAC-layer

grouping, network-layer grouping, IP multicast grouping, etc. Live-FSH16T+ utilizes

port-grouping (port-based VLAN) for the implementation of VLAN in your network.

Port-based VLAN

Live-FSH16T+ simplified the VLAN setup by implementing the most common used VLAN

configuration with a selection switch. The two VLAN modes of Live-FSH16T+ allows users to put

each port in separate VLAN groups while able to share common resources. Users can choose either

14-VLANs or 15-VLANs group. In 14-VLANs mode, each port is in its own VLAN group with

Port 1 and Port 2 as sharing ports. In 15-VLANs mode, each port is in its own VLAN group with

Port 2. The sharing ports are ports that are shared by all VLAN groups for common resources such
