DGS-1200 Series (DGS-1216T, DGS-1224T, DGS-1224TP & DGS-1248T)
IEEE 802.1Q VLAN Tagging
VLANs allow your network to be segmented into
Departmental, Hierarchical, and Security groups and place
a “tag” in a frame to identify which VLAN it belongs to.
This allows 802.1Q-compliant devices to work seamlessly
together to manage VLAN traffic.
Asymmetric VLANs
Asymmetric VLANs are also supported by the DGS-1200
Series. With this feature enabled, VLAN groups can send
information to each other without the traffic going through
a router or a Layer 3 switch. This eliminates expense and
maximizes efficiency while maintaining security.
802.1p Priority Tagging or DSCP-based QoS
The DGS-1200 Series allows users to prioritize traffic
based on 802.1p or DSCP-based (Differentiated Services
Case Point) QoS. Port-based QoS prioritizes all port traffic
with one value, while 802.1p classifies frames according
to their VLAN tag. DSCP-based QoS prioritizes traffic
according to its IP header. DSCP-based QoS and 802.1p
priority tagging prioritizes traffic such as VoIP as it enters
the switch, ensuring that your data is always clear and
jitter-free.
Link Aggregation
The DGS-1200 Series supports Static Link Aggregation,
which “trunks” multiple ports together to function as a
single, high-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). This is accomplished by enabling larger, more
efficient payloads per packet. The DGS-1216T, DGS-1224T,
and DGS-1224TP support Jumbo Frames up to 10KB in size
while the DGS-1248T supports Jumbo Frames up to 9220
bytes in size.
IGMP Snooping
IGMP Snooping allows for the forwarding of multicast
packets, such as streaming audio and video, without
increasing network congestion. By snooping IGMP
registration information within a frame, a list of
workstations in the multicast group is created. The
switch uses this list to intelligently forward packets to the
appropriate workstations.
Cable Diagnostics
Because your connection is just as important as the
switch itself, the DGS-1200 Series is designed with a
cable diagnostic feature that detects transmission errors
and the condition of cables attached to the switch’s
Gigabit copper ports. Cable Diagnostics make it easier
to troubleshoot cabling issues through a web-based
interface and keep all connections up.
Advanced Management Features
The DGS-1200 Series supports SNMP v1, a useful tool
in managing and controlling SNMP-supported network
devices. SNMP enables the switches to provide valuable
information about the switch’s status and send traps
on abnormal events. This sharing of vital management
information saves time and money.
The DGS-1200 Series also supports 802.1D Spanning
Tree, which provides protection from universal cabling
loops forming within a network infrastructure. Spanning
tree detects and breaks these loops, ensuring network
uptime.
Management Utility
In addition to the Web-based Management Interface, the
DGS-1200 Series also ships with the D-Link SmartConsole
Utility. This utility provides a valuable tool in managing,
planning, and troubleshooting network configurations.
Managing a Web Smart switch takes only minutes. With
full color graphics, diagrams, and easy-to-understand
navigation menus, using the SmartConsole Utility is as
easy as surfing the web. The SmartConsole Utility also
includes:
Discovery List – Automatically detects and displays up to
254 D-Link Web Smart Switches on your network along
with their MAC addresses
Monitor List – Monitors switch status and any trap
messages sent to a designated station
Trap View – Notifies the administrator whenever an
abnormal event occurs on the switch
Device Setting – Allows the administrator to set up the
switch’s IP Address, Subnet Mask, Gateway, Send Trap to
Address, System Name, Password, and Location
With its green sensibility and easy-to-use, robust
feature set, the DGS-1216T, DGS-1224T, DGS-1224TP, and
DGS-1248T make a great solution for any growing
business.
