DES-3052PEOL EOS

Managed 48-Port 10/100 Stackable PoE Switch + 4 Gigabit Ports + 2 Combo SFP Slots

Description

The DES-3028/52 series is managed layer 2 Fast Ethernet switches, designed as premium devices in an entry-level network management category. These switches offer a rich set of security functions and an effective network setup at an affordable cost. Outstanding features include Power over Ethernet1, four Gigabit uplink combo ports, high port densities, granular bandwidth control and extensive network management functions. These switches deliver maximum results while remaining a full-featured and cost-effective solution for businesses.

High Port Density & PoE Support
The DES-3028/52 series provides flexible choices of 24 or 48 Fast Ethernet ports, with or without PoE1 in low profile rack-mount cases. Each switch is equipped with four Gigabit Ethernet ports including the two combo SFP capable of both Gigabit and 100BASE-FX fiber connections for user-specific applications.

Security & Availability
The DES-3028/52 series supports 802.1X Port-based/Host-based Access Control, Guest VLAN, and RADIUS and TACAS+ 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 and also to define the 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 by 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 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-3028/52 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 event of any fail-over switch on the network. The switches also support 802.3ad Link Aggregation, which enable you to group multiple ports in parallel to form a single port, increasing bandwidth and redundancy for higher availability. For the 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, IPv4, 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 to manage bandwidth. It also provides fine granularity to define the ingress/egress traffic limits down to 64Kbps 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 traffic 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-3028/52 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-3028/52 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-configuration, an enhanced management feature allows administrators to pre-set configuration and save them in a TFTP server. Individual switches can then boot their IP addresses from the server and load in 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 help businesses, better manage their network topology. Each port on the switches also support Cable Diagnostic feature that helps detect cable related problems such as length or cable functionality. The 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.
