Chapter 1: Introduction
Welcome
This guide covers three product models.
•
SRW2008 - 8-port 10/100/1000 Ethernet Switch with WebView.
Includes 8 10/100/1000 RJ-45 ports and 2 shared MiniGBIC slots.
•
SRW2008MP - 8-port 10/100/1000 Ethernet Switch with WebView and
Maximum POE (Power over Ethernet)
Includes 8 10/100/1000 RJ-45 ports and 2 shared MiniGBIC slots.
•
SRW2008P - 8-port 10/100/1000 Ethernet Switch with WebView and POE (Power over Ethernet)
Includes 8 10/100/1000 RJ-45 ports and 2 shared MiniGBIC slots.
For the purpose of this manual, whenever a feature applies to all models, the model number will be referenced as
SRW2008x. If a specific model number is mentioned, then the feature is specific to that model.
The Linksys WebView Managed switch allows you to expand your network securely. Configuration of the switch is
secured using SSL for Web access. User control is secured using 802.1x security using a RADIUS authentication
mechanism and can also be controlled using MAC-based filtering.
Extensive QoS features makes the solution ideal for real-time applications like Voice and Video. The 4 priority
queues together with the Weighted Round Robin and Strict Priority scheduling techniques facilitate efficient
coexistence of real-time traffic with data traffic allowing them each to meet their QoS needs. Individual users or
applications can be prioritized above others using various Class of Service options - by port, layer 2 priority
(802.1p), and Layer 3 priority (TOS or DSCP). Intelligent Broadcast, and Multicast storm control minimizes and
contain the effect of these types of traffic on regular traffic. IGMP Snooping limits bandwidth-intensive video
traffic to only the requestors without flooding to all users. Incoming traffic can be policed and outgoing traffic can
be shaped allowing you to control network access and traffic flow.
There are features that allow you to expand and grow your network of switches. Link aggregation allows multiple
high-bandwidth trunks between switches to be setup. This also provides a level of reliability in that the system
continues to operate if one of the links break. Spanning Tree (STP), Fast Spanning Tree, and Rapid Spanning Tree
(RSTP) allow you to build a mesh of switches increasing the availability of the system.
The rich management functionality of the WebView switches includes SNMP, RMON, Telnet, and HTTP
Management options, allowing you to flexibly integrate and manage these devices in your network.

Security Tab - Port Security
Network security can be increased by limiting access on a specific port only to users with specific MAC
addresses. MAC addresses can be dynamically learned or statically configured. Locked port security monitors
both received and learned packets that are received on specific ports. Access to the locked port is limited to
users with specific MAC addresses. These addresses are either manually defined on the port, or learned on that
port up to the point when it is locked. When a packet is received on a locked port, and the packet source MAC
address is not tied to that port (either it was learned on a different port, or it is unknown to the system), the
protection mechanism is invoked, and can provide various options. Unauthorized packets arriving at a locked port
are either:
•
•

•
Forwarded
Discarded with no trap
Discarded with a trap
Cause the port to be shut down.

QoS
Network traffic is usually unpredictable, and the only basic assurance that can be offered is best effort traffic
delivery. To overcome this challenge, Quality of Service (QoS) is applied throughout the network. This ensures that
network traffic is prioritized according to specified criteria, and that specific traffic receives preferential
treatment. QoS in the network optimizes network performance and entails two basic facilities:
Classifying incoming traffic into handling classes, based on an attribute, including:
•
•
•
The ingress interface
Packet content
A combination of these attributes
Providing various mechanisms for determining the allocation of network resources to different handling classes,
including:
•
•
•
The assignment of network traffic to a particular hardware queue
The assignment of internal resources
Traffic shaping
The terms Class of Service (CoS) and QoS are used in the following context:
CoS provides varying Layer 2 traffic services. CoS refers to classification of traffic to traffic-classes, which are
handled as an aggregate whole, with no per-flow settings. CoS is usually related to the 802.1p service that
classifies flows according to their Layer 2 priority, as set in the VLAN header.
QoS refers to Layer 2 traffic and above. QoS handles per-flow settings, even within a single traffic class.

Appendix A: About Gigabit Ethernet and Fiber Optic Cabling
Gigabit Ethernet
Gigabit Ethernet runs at speeds of 1Gbps (Gigabit per second), ten times faster than 100Mbps Fast Ethernet, but
it still integrates seamlessly with 100Mbps Fast Ethernet hardware. Users can connect Gigabit Ethernet hardware
with either fiber optic cabling or copper Category 5e cabling, with fiber optics more suited for network
backbones. As the Gigabit standard gradually integrates into existing networks, current computer applications
will enjoy faster access time for network data, hardware, and Internet connections.
Fiber Optic Cabling
Fiber optic cabling is made from flexible, optically efficient strands of glass and coated with a layer of rubber
tubing, fiber optics use photons of light instead of electrons to send and receive data. Although fiber is physically
capable of carrying terabits of data per second, the signaling hardware currently on the market can handle no
more than a few gigabits of data per second.
Fiber cables come with two main connector types. The most commonly used fiber optic cable is multi-mode fiber
cable (MMF), with a 62.5 micron fiber optic core. Single-mode fiber cabling is somewhat more efficient than
multi-mode but far more expensive, due to its smaller optic core that helps retain the intensity of traveling light
signals. A fiber connection always require two fiber cables: one transmits data, and the other receives it.
Each fiber optic cable is tipped with a connector that fits into a fiber port on a network adapter, hub, or switch. In
the USA, most cables use a square SC connector that slides and locks into place when plugged into a port or
connected to another cable. In Europe, the round ST connector is more prevalent.
You must use the Linksys MGBT1, MGBSX1, or MGBLH1 mini-GBIC modules with the Linksys Gigabit Switches.
The MGBSX1 and the MGBLH1 require fiber cabling with LC connectors, and the MGBT1 requires a Category 5e
Ethernet cable with an RJ-45 connector.

Appendix B: Windows Help
Almost all networking products require Microsoft Windows. Windows is the most used operating system in the
world and comes with many features that help make networking easier. These features can be accessed through
Windows Help and are described in this appendix.
TCP/IP
Before a computer can communicate within a network, TCP/IP must be enabled. TCP/IP is a set of instructions, or
protocol, all PCs follow to communicate over a network. This is true for wireless networks as well. Your PCs will
not be able to utilize wireless networking without having TCP/IP enabled. Windows Help provides complete
instructions on enabling TCP/IP.
Shared Resources
If you wish to share printers, folder, or files over your network, Windows Help provides complete instructions on
utilizing shared resources.
Network Neighborhood/My Network Places
Other PCs on your network will appear under Network Neighborhood or My Network Places (depending upon the
version of Windows you're running). Windows Help provides complete instructions on adding PCs to your
network.
