The DES-3200 Series is the new member of D-Link’s Layer 2 xStack Managed Switch family designed for the Metro ETTX and FTTX market. The DES-3200 Series provides 8/16/24 100Mbps Fast Ethernet connections plus 2/4 combo Gigabit/SFP ports. The DES-3200-10/18 comes with a 9-inch desktop size and fanless feature which is suitable for ETTH deployment. The DES-3200-28/28F provides copper or fber connections on Fast Ethernet, an advantage in different Metro Ethernet applications. It also offers the benefcial design of 4 Gigabit/SFP Combo ports which provide up to 4Gbps 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/MAC-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 defned 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 signifcant role in keeping the network secure and auditable. The built-in D-Link Safeguard Engine identifes and prioritizes “CPU interested” packets to prevent malicious traffc from interrupting normal network fows 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 confgure the switch with a redundant backup bridge path, so transmission and reception of packets can be guaranteed in event of any fail-over switch on the network. The switches also support 802.3ad Link Aggregation, which enables 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 traffc classifcation into 8 priority levels mapped to 4 queues. Packet classifcation is based on TOS, DSCP, MAC Addresses, IP Addresses, VLAN ID, TCP/UDP port number, protocol type and user defned packet content, which enables fexible confguration especially for real-time streaming multimedia applications such as voice over IP.

Traffc & Bandwidth Control
The bandwidth control feature allows network administrators to defne the throughput levels for each port to manage bandwidth. It also provides fne granularity to defne the ingress/egress traffc limits down to 62.5kbps segments. The switches also support the Broadcast Storm Control feature, which minimizes the chances of a virus attack within the network. Port Mirroring helps administrators facilitate traffc diagnostics or track switch performance and alter if it is 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 traffc 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 Auto-Confguration is an enhanced management feature that allows administrators to pre-set confguration 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 confguration. 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 switches also supports the Cable Diagnostic feature that helps detect cable related problems such as cable length status or cable functionality. D-Link Single IP Management (SIM) simplifes and speeds up management tasks, allowing multiple switches to be confgured, monitored and maintained from any workstation running a web browser through one unique IP address. Furthermore, 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 in a consistent way. D-View 6.0 provides a useful set of tools for network administrators who want to effectively manage device confgurations, fault tolerance, performance, and security.
