The DES-3200 Series is a member of D-Link’s Layer 2 Managed Switch family designed for the ETTX, FTTX, and enterprise markets. This Series provides 10/16/24/48 Fast Ethernet ports plus 2/4 combo Gigabit/SFP slots. The DES-3200-10/18 comes in a 9-inch desktop size and incorporates a fanless design suitable for ETTH deployment. The DES-3200-28/52 provide copper connections on Fast Ethernet, an advantage when used for Metro Ethernet applications. They also offer the beneficial design of 2/4 Gigabit/SFP Combo slots which provide up to 4 Gbps uplink bandwidth or dual Ethernet ring topology support. The DES-3200-28P/52P are IEEE 802.3af /802.3at -compliant switches that provide 15.4W in every port and up to 30 W on a number of ports for Power over Ethernet (PoE) applications that require extra powers.
Metro Ethernet Forum (MEF) certification for Carriers and Internet Service Providers
D-Link a pioneer in the industry has received the first round of MEF 21 for the DES-3200 Series. The MEF 21 certification guarantees that the DES-3200 Series meets the highest standards on OAM (Operations Administration Maintenance). The Connectivity Fault Management (CFM) feature provides tools to monitor and troubleshoot end-to-end Ethernet networks, allowing service providers to check connectivity, isolate network issues, and identify affected customers without the need to send a support technician to the site. D-Link Unidirectional Link Detection (DULD) provides discovery mechanisms based on IEEE 802.3ah to discover unidirectional traffic issues that can affect fibre links.
Security & Availability
The DES-3200 Series supports 802.1x Port-based/Host-based Access Control, Guest VLAN, RADIUS and TACACS+ 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 built-in D-Link Safeguard Engine identifies and prioritises “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 Spanning Tree (STP), Rapid Spanning Tree (RSTP) and Multiple Spanning Tree (MSTP). STP allows you to configure the switch with redundant backup bridge path, so transmission and reception of data frames can be guaranteed in the event of any failed switch on the network. The Series also supports Link Aggregation Control Protocol (LACP), 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 DES-3200 supports advanced packet classification is based on TOS, DSCP, MAC address, IP addresses, VLAN ID, TCP/UDP port number, protocol type and user-defined packet content. This enables flexible configuration for specific multi-media applications such as IPTV. Additionally, the DES-3200 Series supports automatic, effective QoS function for voice traffic with the Auto Voice VLAN feature, which automatically places voice traffic into a dedicated VLAN with higher priority to guarantee the quality and security of voice conversations.
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. Bandwidth can also be effectively managed for multicast applications like Video On Demand (VoD) with the IGMP snooping and MLD snooping features, to limit multicast traffic only to Switch ports where subscribers connect, optimising the overall network performance. The Switches also support the Broadcast Storm Control feature which minimises the chance of a virus outbreak 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.
The DES-3200 series supports standard management protocols such as SNMP, RMON, Telnet/SSH/SSL and DHCP Relay Option 82. A web-based GUI is also supported for user-friendly interface and easy management. DHCP Auto-Configuration is an enhanced management feature that allows administrators to pre-set configurations 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. 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 7 software. D-View 6.0 is a SNMP-compatible Network Management System to centrally manage critical network characteristics such as availability, reliability, resilience, and security. D-View 7 provides a useful set of tools for network administrators who want to effectively manage device configurations, fault tolerance, performance, and security.
The DES-3200 Series is fully compliant with the future IPv6 network. As the need for larger addressing spaces and higher security become critical, DES-3200 Series support IPv6 ACL, IMPBv6, and Neighbour Discovery (ND) Snooping functions to protect the network from illegal IPv6 clients. The DES-3200 Series has been certified with the IPv6 Ready Logo Phase 2 for full IPv6 application support.
D-Link Green Technology
D-Link is striving to take the lead in developing innovative and power-saving technology that does not sacrifice operational performance or functionality. The DES-3200 Series implements D-Link Green 3.0 Technology, which includes a power saving mode, smart fan, reduced heat dissipation, and cable length detection. The power-saving features include being able to schedule when to turn off LEDs and ports when not in use, and when to make the switch enter hibernation mode. The switches can also detect the length of connected cables to automatically adjust power usage by saving energy on shorter cable connections of up to 20 meters. The switches can also support power-saving by link status, which drastically reduces power consumption by automatically toggling ports without a link to sleep mode. The DES-3200-28P/52/52P feature built-in smart fans. Using a thermal sensor that can detect temperature change, the fans can react accordingly by utilising different fan speeds for different temperatures. The Smart Fan feature enables the built-in fans to automatically turn on at a certain temperature, providing continuous, reliable and eco-friendly operation of the Switch.
