Datasheet

The DES-1228P Web Smart™ Switch from D-Link
®
is a
cost-effective solution for small and medium businesses that
require basic management features, showcased in a low
cost, easy to configure, and GUI-managed ‘smart’ business
solution. The DES-1228P comes with 24 10/100Base-TX
PoE ports, 4 1000Base-T copper interfaces for uplinking
to Storage Area Network (SAN) devices, servers, or core
switching solutions, and 2 combo SFP fiber slots for long
haul uplinking via optional 100Base-FX or 1000Base-X
transceivers. The DES-1228P is more versatile than ever
with integrated wireless switching features. Whether the
end nodes are a wired PC workstation or a wireless client,
such as the Web Smart DWL-3140AP, the entire network can
be managed via a single unified wired/wireless platform.
Security
The DES-1228P incorporates advanced mechanisms that
detect attacks against the switch’s central processing unit
and take corrective action on the attacking interface. When
a Denial of Service attack is waged against the
DES-1228P, the D-Link Safeguard Engine™ prevents overload
of the central processor, ensuring network integrity and
maintaining open network bandwidth channels. The
DES-1228P also supports 802.1x Authentication, which
provides a secure means to allow users to log onto your
network. When used in conjunction with a RADIUS server,
802.1x requires each user to provide their username and
password before accessing the local area network.
Unified Wireless and Wired
1
With no additional costs or license purchasing necessary,
administrators can monitor wired and wireless nodes via
a central web interface. Supporting WEP, WPA, and WPA2
authentication, the DES-1228P can manage up to 24 access
points and up to 200 clients. The unified Web Smart Switch
provides access point configuration with the click of a
button, even with multiple access points!
The Web Smart Switch provides wireless connectivity
through the 802.11g Web Smart Access Point (DWL-3140AP).
This AP has a discrete, ceiling-mount, smoke detector form
factor for easy deployment. All of your D-Link Web Smart
Switches and Web Smart Access Points are automatically
discovered with the included web-based browser utility,
allowing network topology and layout generation in seconds
at no additional cost.
Link Aggregation
The DES-1228P supports static link aggregation to combine
port bandwidth in data-intensive applications. You can
combine up to 8 ports for a total of six aggregate groups.
Ports can be combined together to create multi-link load
sharing groups to a server or a network backbone. To expand
the network, you can also make use of link aggregation to
eliminate bottlenecks between cascaded switches.
802.1Q VLANs
The DES-1228P provides support for 802.1Q VLANs,
improving security and bandwidth utilization. VLANs
segment broadcast domains to reduce network congestion
caused by constant network broadcasting. VLANs also provide
a means of securing one broadcast domain from all others.
This in turn prevents users on one VLAN from gaining access
to resources on another VLAN.
Asymmetric VLANs
The Web Smart Switch also supports asymmetric VLANs.
With this feature enabled, VLAN groups will be able to send
information to each other without the traffic going through
a router or a Layer 3 switch. This eliminates the need to
purchase an additional routing device or burdening the
router with internal communications, maximizes network
efficiency, and securely segments the group via the
VLAN.
802.1p Priority Tagging
Like 802.1Q VLAN tagging, 802.1p places a tag in a frame to
indicate frame priority. The tag represents a priority of 0-7,
which 802.1Q-compliant switches use to prioritize traffic.
Unlike port-based QoS, which prioritizes all traffic entering a
