The  DES-1228  Web  Smart  Switch  from  D-Link

®

  is  a  

cost-effective solution for the small and medium business 
that  requires  basic  management  features  like  VLAN 
segmentation, QoS prioritization, and secure 802.1x login 
and authentication. This is all showcased in a low cost, 
easy  to  configure,  and  GUI-managed  ‘smart’  business 
solution.  The  DES-1228  comes  with  24  10/100BASE-TX 
ports, 4 1000BASE-T with 2 combo fiber SFP interfaces 
for uplinking to storage area network devices, servers, or 
core switching solutions. The Graphical User Interface 
allows you to implement Quality of Service (QoS), VLANs 
and  security  without  having  to  go  through  complex 
command  line  management  usually  found  in  other 
managed switches.

D-Link Safeguard Engine

The DES-1228 incorporates advanced mechanisms that 
detect an attack against the switch’s central processing 
unit  and  takes  corrective  action  on  the  attacking 
interface.  When  a  Denial  of  Service  attack  is  waged 
against  the  DES-1228,  the  D-Link  Safeguard  Engine

TM

 

detects the threat and prevents overload of the central 
processor,  ensuring  network  integrity  and  helping  to 
maintain open network bandwidth channels.

802.1D Spanning Tree

Spanning  Tree  provides  protection  from  unintentional 
cabling  loops  within  a  network  infrastructure.  Loops 
dangerously create an unending circle where broadcast 
and  multicast  traffic  propagates  across  the  network. 
This storm of traffic overwhelms the network and brings 
traffic to a crawl, but 802.1D Spanning tree detects and 
breaks these loops, ensuring network uptime.

Link Aggregation

The  DES-1228  supports  static  port  trunking  of  up  to  6 
groups  of  8  ports  per  device.  Ports  can  be  combined 
together  to  create  multi-link  loadsharing  aggregated 
trunks to a server or a network backbone. To expand the 
network, you can also make use of link aggregation to 
eliminate bottlenecks between the cascaded switches. 

802.1Q VLANs

The  DES-1228  provides  support  for  802.1Q  VLANs  for 
improved security and bandwidth utilization. VLANs segment 
broadcast domains and reduce network congestion caused 
by  constant  network  broadcasting.  VLANs  also  provide  a 
means  of  securing  one  broadcast  domain  from  all  others. 
This  prevents  users  on  one  VLAN  from  gaining  access  to 
resources on other network segments. VLANs can be further 
configured to segment departmental resources. VLANs can 
be implemented on an SMB network. For example,  to prevent 
one department from gaining access to secure resources in 
another department.

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  and 
prevents flooding the router with internal communications,  
maximizing  network  efficiency,  and  keeping  the  groups 
securely segmented via VLANS.

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 
port with the same value, 802.1p classifies incoming frames 
through  these  sets  of  priorities.  This  means  your  802.1p 
VoIP phone can be granted higher priority than other traffic, 
resulting in phone calls that are clear and jitter-free.

SNMP Management

The  DES-1228  utilizes  SNMP  v1  to  manage  and  control 
SNMP-supported  network  devices.  SNMP  enables  the 
DES-1228  to  provide  valuable  status  information  and 
send  traps  on  abnormal  events.  This  sharing  of  vital 
management information saves time and money.
