Chapter 1: Introduction
Welcome
24-Port 10/100/1000 Gigabit Switch with Webview and PoE
Chapter1:Introduction
Welcome
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 co-
existence 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.

Ports
LAN (1-24) The LAN (Local Area Network) ports connect to Ethernet network devices, such as
other switches or routers.
MiniGBIC (12) /MiniGBIC (24)The Switch is equipped with two mini-GBIC ports. The miniGBIC (gigabit interface
converter) port is a connection point for a miniGBIC expansion module, so the
Switch can be uplinked via fiber to another switch. If a Gigabit mini-GBIC port is
being used, the associated LAN port (12 and/or 24) cannot be used. They link to
high-speed network peripheral system or clients at speeds of 1000Mbps.
Use the Linksys MGBT1, MGBSX1, or MGBLH1 miniGBIC modules with the Switch.
The MGBSX1 and the MGBLH1 require fiber cabling with LC connectors, while the
MGBT1 requires a Category 5e Ethernet cable with an RJ-45 connector.
Console The Console port is where you can connect a serial cable to a PC’s serial port for
configuration using your PC’s HyperTerminal program. Refer to Chapter 4: Using
the Console Interface for Configuration for more information.
The Back Panel
The power port is located on the back panel of the Switch.

The Side Panel
The security slot is located on a side panel.
Security Slot The security slot is where you can attach a lock so the Switch will be protected from theft.
LAN Ports
The Switch is equipped with twenty-four auto-sensing RJ-45 LAN ports. These RJ-45 ports support network
speeds of either 10Mbps, 100Mbps or 1000Mbps, and can operate in half and full-duplex modes. Auto-sensing
technology enables each port to automatically detect the speed of the device connected to it (10Mbps, 100Mbps
or 1000Mbps), and adjust its speed and duplex accordingly.
The Switch’s RJ-45 ports also support the IEEE 802.3af Power-over-Ethernet (PoE) standard that enables DC
power to be supplied to attached devices using wires in the connecting twisted-pair cable. Any 802.3af-
compliant device attached to a port can directly draw power from the Switch over the twisted-pair cable without
requiring its own separate power source. This capability gives network administrators centralized power control
for devices such as IP phones and wireless access points, which translates into greater network availability. For
each attached 802.3af-compliant device, the Switch automatically senses the load and dynamically supplies the
required power. The Switch delivers power to a device using the two data wire pairs in the twisted-pair cable.
Each port can provide up to 15.4 W of power at the standard -48 VDC voltage.To connect a device to a port, you
will need to use Category 5 (or better) network cable.
The Gigabit Expansion Ports
The Switch is equipped with two miniGBIC ports that have shared Gigabit Ethernet ports (12 and 24) which
provide for the installation of one expansion module. These ports provide links to high-speed network segments
or individual workstations at speeds of up to 1000Mbps (Gigabit Ethernet). To establish a Gigabit Ethernet
connection using a mini-GBIC port, you will need to install an MGBT1, MGBSX2, or MGBLH1 Gigabit expansion
