24-port 10/100Mbps PoE + 2 Combo 1000BASE-T/SFP + 2 SFP Ports L2 Managed
The DES-3200 Series is a member of D-Link’s Layer 2 xStack Managed Switch family designed for the
Metro ETTX, FTTX, and Enterprise market. The DES-3200 Series provides 8/16/24 10/100 Mbps Fast
Ethernet connections plus 2/4 combo Gigabit/SFP ports. The DES-3200-10/18 comes in a 9-inch desktop
size and incorporates a fanless design suitable for ETTH deployment. The DES-3200-28/28F and
DES-3200-28/ME provide copper or fiber connections on Fast Ethernet, an advantage when used for Metro Ethernet applications. It also offers the beneficial design of 2/4 Gigabit/SFP Combo ports which provide up to 4 Gbps uplink bandwidth or dual Ethernet ring topology support. The DES-3200-28F facilitates up to 20 km connectivity for Metro Ethernet applications.
Security & Availability
The DES-3200 series supports 802.1X Port-based/Host-based Access Control, Guest VLAN, and
RADIUS and TACAS+ Authentication for strict access control over the network. The IP-MAC-Port Binding
feature allows administrators to bind a source IP address with an associated MAC for a defined port
number to enhance user access control. Furthermore with the DHCP Snooping feature, the switch
automatically understands the IP/MAC pairs by snooping DHCP packets and saving them to the IMPB
white list. These features play a significant role in keeping the network secure and auditable. The builtin D-Link Safeguard Engine identifies and prioritizes “CPU interested” packets to prevent malicious traffic
from interrupting normal network flows and protects switch operation. In addition, the Access Control List (ACL) feature enhances the network security and switch performance.
Resilience/Performance Enhancement
For mission critical environments the DES-3200 series supports 802.1D-2004 edition, 802.1w and
802.1s Spanning Tree Protocols (STP). STP allows you to configure the switch with a redundant backup
bridge path, so transmission and reception of packets can be guaranteed in the event of any failed switch on the network. The switches also support 802.1AX and 802.3ad Link Aggregation, enabling you to group multiple ports in parallel to form a single port, increasing bandwidth and redundancy for higher
availability. For Quality of Service (QoS), the switches support 802.1p. This standard is a mechanism that allows real-time traffic classification into 8 priority levels mapped to 4 queues. Packet classification is based on TOS, DSCP, MAC Addresses, IP Addresses, VLAN ID, TCP/UDP port number, protocol type and user defined packet content, which enables flexible configuration especially for real-time streaming
multimedia applications such as voice over IP.
Traffic & Bandwidth Control
The bandwidth control feature allows network administrators to define the throughput levels for
each port in order to manage bandwidth. It also provides fine granularity to define the ingress/
egress traffic limits down to 62.5 kbps segments. The switches also support the Broadcast Storm
Control feature which minimizes the chance of a virus attack within the network. Port Mirroring helps
administrators facilitate traffic diagnostics or track switch performance and make changes if necessary.
Q-in-Q, also known as VLAN stacking, is a powerful yet simple and cost-effective solution which can
be used to provide multiple virtual connections and access to multiple services available over the
Metro Ethernet.
Multicast Applications
The DES-3200 series provides IGMP Snooping to prune multicast traffic and to optimize network
performance. The MLD snooping feature minimizes multicast IPv6 packets at the port level to conserve
network bandwidth.
Management Capabilities
The DES-3200 series supports standard management protocols such as SNMP, RMON, Telnet, SSH/SSL
security authentication and DHCP Relay Option 82. A web-based GUI is also supported for user-friendly
interface and easy management. DHCP AutoConfiguration is an enhanced management feature that allows administrators to pre-set configuration and save them to a TFTP server. Individual switches
can then get IP addresses from the server for booting up and loading the pre-set configuration. The Link
Layer Discovery Protocol (LLDP) allows a network device to advertise its identity and capabilities on
the local network, which helps businesses better manage their network topology. Each port on the
switch supports the Cable Diagnostics feature that helps to detect cable-related information such as
cable length status or cable functionality. D-Link Single IP Management (SIM) simplifies and speeds
up management tasks, allowing multiple switches to be configured, monitored and maintained from
any workstation running a web browser through one unique IP address. The DES-3200 Series also
works with D-Link’s D-View 6.0 software. D-View 6.0 is a Network Management System that allows
for the central management of critical network characteristics such as availability, reliability,
resilience, and security. D-View 6.0 provides a useful set of tools for network administrators who want
to effectively manage device configurations, fault tolerance, performance, and security.
