D-Link DES-1228P WebSmart Managed Ethernet Switch with PoE
The DES-1228P has been discontinued by the manufacturer. The replacement product is the
DES-1210-28P.
The DES-1228P Web Smart Switch 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 Fast Ethernet
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.
DES 1228P - Security
The DES-1228P incorporates advanced mechanisms to detect
attacks against the central processing unit of the switch and to 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, thus insuring 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 workstation attached to
the DES-1228P to provide a username and password before gaining access
to the local area network.
DES 1228P - Unified Wireless and Wired*
Without additional costs or licensing, the administrator
of the switch can monitor wired or wireless end nodes via a central web
interface. Supporting WEP, WPA, WPA2 authentication, DES-1228P can
manage up to 24 access points and up to 200 clients. The unified web
smart switch facilitates access point deployment by allowing a set of
templates to be created, then distributing the same template to
multiple access points via a simple click of a button. With no
additional license purchase necessary, the Web Smart Switch supports
the 802.11g Web Smart Access Point DWL-3140AP, which has a discrete
smoke detector (ceiling-mount) form factor that facilitates deployment.
All DWL-3140AP and additional D-Link Web Smart switches can be
automatically discovered, allowing network topology and layout to be
generated in seconds.
DES 1228P - Link Aggregation
The DES-1228P supports static port trunking of up to 6
groups of 8 ports per device. Ports can be combined together to create
a fat pipe to a server or a network backbone. To expand the network,
you can also make use of link aggregation eliminating bottlenecks
between cascaded switches.
DES 1228P - 802.1Q VLANs
The DES-1228P provides support for 802.1Q VLANs improving
security and bandwidth utilization. VLANs work by segmenting broadcast
domains, thus reducing network congestion due to constant network
broadcasting. In addition, VLANs provide a means of securing each
broadcast domain from all others. This in turn prevents users on one
VLAN from gaining access to resources on another VLAN.
DES 1228P - 802.1p Priority Tagging
For mission critical packets, the DES-1228P supports
802.1p priority tagging to ensure expedited delivery. This feature
differs from Port-Based QoS in that 802.1priority tagging allows the
administrator to assign and designate the priority of traffic. 802.1p
support is ideal for applications such as voice or video traffic so
that it is delivered clean and jitter free.
DES 1228P - SNMP Management & 802.1D Spanning Tree
The DES-1228P supports SNMPv1. SNMP is a useful tool in
managing and controlling SNMP supported network devices. SNMP enables
the DES-1228P to be polled to provide valuable information about the
status of the unit and send traps on abnormal events. This sharing of
vital management information saves time and money. Furthermore, the
DES-1228P supports Spanning Tree Protocol, which provides protection
from unintentional cabling loops forming within a network
infrastructure. Loops are dangerous in that they create an unending
circle where broadcast and multicast traffic propagate across the
network in an endless loop. This creates a storm of traffic that
overwhelms the network and brings traffic to a crawl. 802.1D Spanning
Tree detects and breaks these loops ensuring network uptime.
DES 1228P - IGMP Snooping
IGMP Snooping enables the forwarding of multicast packets
such as streaming audio and video without increasing network broadcast
congestion. By snooping IGMP registration information within a frame, a
list of workstations that have joined the multicast group is created.
This list then allows the switch to intelligently forward packets to
only the appropriate member workstations.
DES 1228P - Smart Utility
Included with every DES-1228P is a D-Link exclusive
software utility that allows all D-Link smart switches and DWL-3140AP
to be discovered automatically with one click of the button.Managing the
DES-1228P has never been easier. Using its built-in browser-based
management interface, configuring the switch takes only minutes. With
full color graphic pictures, diagrams and easy to understand navigation
menus, configuring the DES-1228P with the features you require is as
easy as surfing the net. The DES-1228P supports many of today’s most
sought after features like 802.1P Priority Queuing, 802.1Q VLANs, Port
Trunking, 802.1x Authentication, Port Mirroring, SNMP, 802.1d Spanning
Tree, Link Aggregation, IGMP Snooping, Broadcast Storm Control, and
more.
