Overview
The DES-3028 and DES-3052 are Managed 10/100 Layer 2
Stackable Switches with 4 Gigabit ports and 2 Combo SFP
slots. The DES-3028P and DES-3052P are also Managed
10/100 Layer 2 Stackable Switches with 4 Gigabit Ports and
2 Combo SFP slots, but include PoE capabilities. With the
option for 24-Ports (DES-3028 and DES-3028P) or 48-Ports
(DES-3052 and DES-3052P), these high port density switches
allow SMBs to set up secure and effective networks at an
affordable cost. With additional features such as enhanced
network security, bandwidth control, and advanced
management, the DES-3028, DES-3028P, DES-3052, and
DES-3052P are cost-effective switches that deliver proven
results.
Enhanced Security
The DES-3028, DES-3052, DES-3028P, and DES-3052P support
many security functions including Access Control List (ACL),
802.1x Port-Based/MAC-Based Access Control, 802.1x Guest
VLAN, and RADIUS/TACACS+ authentication.
The D-Link Safeguard Engine incorporates advanced
mechanisms to detect an attack against the central
processing unit of the switch and to take corrective measures
on the attacking interface. When a Denial of Service attack
is waged against any of the switches, the D-Link Safeguard
Engine detects the threat and prevents the overload of the
central processor, thus insuring network integrity and helping
to maintain open network bandwidth channels.
802.1Q VLANs
The DES-3028, DES-3052, DES-3028P, and DES-3052P
provide support for 802.1Q VLANs for improved security
and bandwidth utilization. VLANs provide a means of
securing each broadcast domain, segregating them from
each other. This in turn prevents users on one VLAN from
gaining access to resources on other network segments.
VLANs can be configured to segment departmental
resources. For example, VLANs can be implemented on an
SMB network to prevent the Marketing department from
gaining access to secure resources in the Accounting
department. Guest VLAN is also supported by DES-3028,
DES-3028P, DES-3052, and DES-3052P, which automatically
segregates unauthenticated visitors from accessing
confidential resources.
QoS
802.1p Priority Tagging helps streamline networks by
placing a priority tag in a specified frame. When this frame
is received by the switch, it is placed in a priority queue,
enabling it to be prioritized ahead of other frames. 802.1p
enables administrators to assign and designate traffic
priority. This process helps applications such as VoIP and
video conferencing to be delivered clear and jitter-free.
DES-3028 supports a variety of different ways to prioritize the
packets to ensure QoS in a busy network.
802.3af Power over Ethernet (DES-3028P and
DES-3052P)
The DES-3028P and DES-3052P are able to supply power
to PoE enabled devices. Each port on the DES-3028P can
support up to 15.4W of power, budgeting a total of 195W
throughout all 24 ports. Each port on the DES-3052P can
also support up to 15.4W of power, budgeting a total of 370W
throughout all 48 ports. This can eliminate the need to place
devices near power outlets and help clean up clutters of
loose wires and cables. For any devices that are not PoE
enabled, PoE Adapters such as the D-Link DWL-P50 can be
used to provide power to non-compliant devices.
IGMP Snooping
By passively snooping IGMP packets that are transferred
between the DES-3028, DES-3028P, DES-3052, or DES-3052P
and the IP multicast host, registration information is
recorded and sorted into multicast groups. These can
then intelligently forward traffic to only those ports
that request multicast traffic. Adversely, without IGMP
snooping, multicast traffic is treated like broadcast traffic,
with packets forwarded to all ports causing network
inefficiencies.
