Introduction
The
D-Link Web Smart Gigabit Switch (DGS-1216T)
blends plug-&-play simplicity with exceptional
performance and reliability to create a
cost-effective solution for bandwidth- starved
workgroups and departments. The DGS-1216T
provides a solution for any size business
with any size need. It supports 2 Combo
fiber SFP uplinks for uplinking to servers,
storage, or other switching devices providing
superior performance with exceptional value.
The DGS- 1216T delivers a high performance
featur set sufficient to monitor and secure
a SMB network efficiently.
Advanced
Management Features
The Web Smart DGS-1216T supports SNMP v1.
SNMP is a useful tool in managing and controlling
SNMP supported network devices. SNMP enables
the Web Smart DGS- 1216T 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.
The
DGS-1216T also supports Spanning Tree, provides
protection from unintentional cabling loops
forming within a network infrastructure.
802.1D Spanning tree detects and breaks
these loops ensuring network uptime.
Advanced
Security
The DGS-1216T provides a robust set of security
features normally found only in fully managed
switching solutions. It is equipped with
the D-Link Safeguard Engine to protect the
CPU from malicious attack. When frames enter
the switch, the D-Link Safeguard Engine
detects and blocks broadcast, multicast,
and unicast flooding which can overload
a CPU and bring network traffic to a halt.
In addition, the DGS-1216T also provides
support for secure encrypted 802.1x port
based user authentication, broadcast storm
control, and up to 256 static MAC address
entries.
IEEE
802.1Q VLAN Tagging
A VLAN (Virtual LAN) is a collection of
computers that are grouped together. VLANs
allow the network to be segmented into groups
(Departmental, Hierarchical, and Security
Groups). 802.1Q is a standard that places
a “tag” in a frame identifying
which VLAN it belongs to. The advantage
of this is that all 802.1Q compliant devices
can work seamlessly together to manage VLAN
traffic.
802.1p
Priority Tagging
Like 802.1Q VLAN tagging, 802.1p places
a tag in a frame to indicate the priority
of the frame. This differs from port-based
QoS in that, in port based QoS, all traffic
entering a specific port is prioritized
the same way with the same value. In 802.1p,
a port can receive frames with varying priority
tags and classify them based on these tags.
For example, a VoIP phone that supports
802.1p can assign a priority to its VoIP
traffic. When it enters the switch, the
switch can then prioritize it so that voice
traffic is always clear and jitter-free.
Link
Aggregation
The DGS-1216T supports static link aggregation.
Link aggregation provides a means of “trunking”
multiple ports together to function as a
single large bandwidth channel. When a high-bandwidth
channel is needed to uplink to another switch,
link aggregation makes this process simple
and hassle-free.
Jumbo
Frame Support
Jumbo Frame support is designed to improve
network throughput and significantly reduce
the CPU utilization of large file transfers
(such as multimedia files or large data
files) by enabling more efficient larger
payloads per packet. The DGS-1216T supports
Jumbo Frames up to 10KB in size.
Web
Management Utility
The DGS-1216T includes the D-Link Web Smart
Management Utility. This utility provides
a valuable tool in managing, planning, and
troubleshooting network configurations.
Managing a DGS-1216T Web Smart switch takes
only minutes. With full color graphic pictures,
diagrams, and easy to understand navigation
menus, using the Web Smart Management Utility
is as easy as surfing the Internet. Some
of the features include:
Discovery List – Every Smart DGS-1216T
comes with auto-discovery software that
automatically detects and displays up to
254 D-Link Web Smart switches running on
your network along with a list of their
MAC addresses.
Monitor List - The DGS-1216T can be monitored
for status and trap messages sent to a designated
station.
Trap View – When an abnormal event
occurs on the switch, traps can be set to
notify the system administrator.
Device Setting – The Device Setting
feature of the Web Management Utility allows
the network administrator to set the IP
Address, Subnet Mask, Gateway, Send Trap
To Address, System name, password, and Location
of the DGS-1216T.
With
an easy to use web-based interface and a
robust feature set, the DGS-1216T makes
a great solution for any growing business.
