Where to buy

Description

The DES-1228/ME is a managed layer 2 Fast Ethernet switch, designed as a premium device for entry-level network management devices. These switches offer a rich set of security functions and an effective network setup at an affordable cost. Outstanding features include four Gigabit uplink combo ports, high port densities, granular bandwidth control and extensive network management functions. This switch delivers maximum results while remaining a full-featured and cost-effective solution for businesses.

High Port Density & SFP Ports
The DES-1228/ME provides 24 Fast Ethernet ports, and is equipped with four Gigabit Ethernet ports including two combo SFP ports capable of both Gigabit and 100BASE-FX fiber connections for user-specific applications.

Security & Availability
The DES-1228/ME supports 802.1X Port-based/Hostbased 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. 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-1228/ME supports 802.1D-2004 edition, 802.1w and 802.1s Spanning Tree Protocols (STP). STP allows you tho 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 switch also supports 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. The DES-1228/ME supports 802.1p Quality of Service (QoS). This standard is a mechanism that allows realtime 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. The DES-1228/ME provides IGMP Snooping to prune multicast traffic and to optimize network performance.

Management Capabilities
The DES-1228/ME supports standard management protocols such as SNMP, RMON, Telnet, SSH security authentication and DHCP Relay Option 82. A web-based GUI is also supported for user-friendly interface and easy management. DHCP autoconfiguration, 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.
