D-Link DGS-3100-24 DGS-3100-24/A User Manual

Managed L2 Stackable Gigabit Switches

The  DGS-3100  series  switches  are  managed 

Layer 2 Gigabit stackable switches designed as 

feature-rich, cost-effective devices in the entry-

level  network  management  category.  These 

switches  provide  wide-ranging  port  densities 

and up to 20Gbps physical stacking. Outstanding 

features  include  scalable  expansion,  SFP  fiber 

links, comprehensive network security, granular 

bandwidth  control  and  extensive  network 

management.  Small  to  medium  businesses 

(SMBs)  looking  for  a  flexible,  advanced  and 

affordable solution can deploy these switches to 

set up Gigabit connections to their desktops or 

build up a company-wide network backbone.

Physical Stacking

Each of the DGS-3100 series switches comes with 

2 dedicated HDMI stacking ports, each providing 

5Gbps stacking bandwidth (up to 20Gbps for the 

overall system in full-duplex mode, bi-directional). 

Up  to  6  units,  288  10/100/1000Mbps  ports  can 

be  stacked  up  in  a  linear  or  fault-tolerant  Ring 

topology. A stack can consist of 10/100/1000Mbps 

switches,  10/100/1000Mbps  PoE  switches,  or 

a combination of both types, with up to 96 SFP 

fiber links. Units can be gradually added to the 

stack to accommodate growth, while expansion 

beyond a single stack is possible using Gigabit 

port  trunks  between  stacks,  or  from  stack  to 

network backbone and server paths.

Security & Availability

The  DGS-3100  stack  includes  many  security 

features  including  Access  Control  List  (ACL), 

802.1X  Port-Based/Host-Based  Access  Control 

and  802.1X  Guest  VLAN  to  make  network 

access available to authorized users. To prevent 

malicious attacks and virus/worm affection from 

overwhelming  the  switch  with  unnecessary 

workload,  the  DGS-3100  stack  provides  the 

D-Link Safeguard Engine function to increase the 

switch’s reliability and availability.

Resilience/Performance Enhancement

To  enhance  network  resilience,  the  DGS-

3100  stack  provides  Spanning  Tree  protocols, 

including 802.1D, 802.1w and 802.1s for redundant 

bridge paths. 802.3ad Link Aggregation provides 

the aggregated bandwidth between switches or 

server. For Quality of Service (QoS), it supports 

802.1p Priority Queues and packet classification 

based on TOS, DSCP, MAC, IP, VLAN ID and L4 

protocol types, enabling Internet voice, video and 

streaming media applications to run smoothly. 

Traffic Monitoring/Bandwidth Control

Network  administrators  can  define  throughput 

levels  for  each  port  to  manage  bandwidth. 

The  bandwidth  control  feature  provides  fine 

granularity  with  the  ability  to  define  bandwidth 

limits  down  to  64Kbps  segments.  Broadcast 

storm  control  can  reduce  the  level  of  damage 

that  a  virus  attack  can  do  to  the  network.  The 

switch  provides  IGMP  snooping  and  MLD 

snooping to control multicast transmission, and 

port mirroring to facilitate diagnostics.

Management

The  DGS-3100  stack  supports  standard-

based 

management  protocols  such  as  SNMP, 

RMON,  Telnet,  Web  GUI  and  SSH/SSL  security 

authentication. With DHCP autoconfiguration,the 

administrator  can  pre-set  configurations  and 

save  them  in  a  TFTP  server,  and  individual 

switches can boot their IP from the server and 

load in the pre-set configurations.
