Switches by functionality

Energy-saving D-Link Green technology

is standard across the Smart Switch series

along with the integrated D-Link Safeguard

engine to protect against excessive

network trac ows. Each also oers

support for a variety of bandwidth and

security management features.

The Smart Switch

Smart switches add to the basic Layer

2 trac capabilities of the Unmanaged

Switch by incorporating a variety of

extra features, although in the main

they don’t require Layer 3 functionality

to do so.

The “smart” extras can be simple

options such as the ability to enable/

disable individual ports, set port

speed and so on. They can also be

more complex, such as managing

bandwidth limits; grouping ports

to create one or more Virtual LANs

(VLANs); or aggregating ports together

to provide high-speed links to servers

and other switches. Most also allow

for trac to be prioritised using

industry-standard protocols to weight

the importance of the applications

concerned.

Because they oer additional features

that need to be congured and

monitored, Smart Switches have a

built-in management interface. Access

to this via a browser is the hallmark of

the Smart Switch, although support for

remote Simple Network Management

Protocol (SNMP) and command line

management tools is to be had on

some products.

Key selling points:

More functionality than an

Unmanaged Switch, easy to congure

than fully managed solutions; priced

to appeal to the small business; rack-

mount or desktop use.

Look for:

Compliance with industry standards;

high port density (up to 48 ports/

switch); support for bre optic

connectivity for uplinks; Power over

Ethernet (PoE), comprehensive security

features

Where are they used?

Smart Switches can be used to build

small to medium sized networks

where control over trac ow is

important but the company lacks

the technical expertise or budget to

implement a fully managed solution.

Particularly useful where Voice

over IP (VoIP) telephony and video

conferencing are deployed and where

the network needs to be divided up

into separate VLANs.

These switches are common in small

to medium sized companies. In larger

enterprises, Smart Switches can be

installed at the edge of the network (in

branch oces, for example) to deliver

advanced trac management and

Quality of Service (QoS) features at an

aordable price, with uplinks back to a

managed core network.
