Overview
For the SMB requiring a cost-effective core switching
solution, as well as for larger Enterprise and Metropolitan
Service Providers (MSP) environments needing a
managed, feature-rich switch capable of uplinking
to backbone switches, the D-Link xStack DES-3852 is
designed to meet the needs of the most demanding
departmental and enterprise connectivity applications.
The xStack DES-3852 Switch is a fully managed Layer
3 switch that provides (48) 10/100Mbps Fast Ethernet
ports and (2) Combo SFP/1000BASE-T Gigabit Ethernet
uplinks. In addition, (2) fi xed1000BASE-T ports in the
back-panel can provide a dedicated trunk connection
between devices or core switches. The xStack DES-3852
also provides virtual stacking functionality via D-Link
SIM technology allowing up to 32 units to be managed
via a single IP address. With support for Q-in-Q Double
VLAN tagging, IPv6 aware
1
, Dynamic Layer 3 Routing,
IEEE802.1s, and bandwidth control, the xStack DES-3852
incorporates advanced features suitable for the MSP as
well as the SMB and Enterprise size network.
Metro Switching
Service provider networks are moving from circuit-based
access to newer packet-based access that will require
highly reliable intelligent switching, and at the same
time demand resiliency and dependability. The xStack
DES-3852 meets this demand by supporting industry
standards for 802.1s (multiple spanning tree), 802.3ad link
aggregation for up to 32 groups, bandwidth rate limiting
down to 64k, and support for an external redundant
power option for added peace of mind. In addition the
xStack DES-3852 offers Double VLAN Q-in-Q tagging,
which adds on an additional tag to a VLAN tag, expanding
the VLAN space and allowing service providers to deploy
their service quickly and securely. The xStack DES-3852
also incorporates advanced QoS support such as the
ability to fi lter and forward traffi c based on Layer 2/3/4,
making it an ideal choice for VoIP, video, and audio
services targeting business class customers.
Advanced L3 Routing
The xStack DES-3852 is a high performance Layer
3 switch that provides an ideal solution by offering
advanced Layer 3 routing features such as RIP, OSPF,
VRRP, up to 10 IP addresses per VLAN, and fl oating static
routes. Policy Based routing
1
(which forwards traffi c
based on L3/L4 SA/DA) and Multi-Path Routing
1
(which
is the method of establishing multiple paths between
given source-destination nodes within a network) are
also features supported on the xStack DES-3852. These
added routing features provide redundancy, improve
network utilization, and provide load balancing for the
network.
Comprehensive Security
The xStack DES-3852 incorporates an advanced portfolio
of security features designed to protect your network from
malicious attacks. SSH & SSL encrypted management
guarantee secure private confi guration and monitoring
when using the Graphical User Interface and Command
Line. IP to MAC binding prevent unauthorized devices
from accessing network resources. 802.1x port and
MAC based authentication help provide added network
security by requiring all users attempting to connect to
your network, provide a username and password. This
username and password must then be authenticated on a
RADIUS or TACACS+ server thus insuring only authorized
users have access to the network. Access control lists
based on Layers 2/3/4, Rate Limiting, and Guest VLANs
provide even more control over what and how users
access the network. Finally with D-Link’s CPU Safeguard
Engine, the DES-3852 is protected from Broadcast,
Multicast, and Unicast fl ooding which in turn guarantees
the DES-3852 is not crippled by DoS attacks.
