24 10/100Mbps + 2 100/1000 SFP + 2 Combo 100/1000Base-T/SFP Ports L2 MetroEthernet Switch
Kur įsigyti


The DES-1228/ME Managed L2 Fast Ethernet Switch is a managed layer 2 Fast Ethernet switch that is designed to be an entry-level network management device with a premium feature set. It offers a rich set of security functions and an effective network setup at an affordable cost. Connectivity includes 24 copper connections on Fast Ethernet, and 2/4 Gigabit/SFP Combo ports which provide up to 4 Gbps uplink bandwidth or dual Ethernet ring topology support. This design enables the switch to deliver maximum handling results while remaining a full-featured and cost-effective solution for businesses.
Security & Availability
DES-1228/ME supports 802.1X port-based/host-based access control, Guest VLAN, and RADIUS 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 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 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 the switch to be configured with a redundant backup bridge path, so transmission and reception of packets can be guaranteed in the event of any fail-over switch on the network. The switch also supports 802.3ad Link Aggregation, which enables multiple ports to be grouped in parallel to form a single port, increasing bandwidth and redundancy for higher availability. The DES-1228/ME also supports 802.1p Quality of Service (QoS), allowing for 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 for flexible configuration for specific multimedia applications such as VoIP or IPTV.
Traffic & Bandwidth Control
Bandwidth control 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 62.5 Kbps segments. The DES-1228/ME also supports Broadcast Storm Control, which minimizes the chances of a virus attack within the network, and Port Mirroring helps administrators facilitate traffic diagnostics or track switch performance, and make changes if necessary. The DES-1228/ME also provides IGMP Snooping to prune multicast traffic and to optimize network performance.
Multicast Applications
The DES-1228/ME provides a full set of L2 multicast functions, including IGMP snooping, IGMP filtering, fast leave, and multicast traffic configuration for specific ports. With L2 Multicast support, the DES-1228/ME is ready and capable of handling growing IPTV applications. Host-based IGMP/MLD1 Snooping allows for multiple multicast subscribers per physical interface, and ISM VLAN sends multicast streams in a multicast VLAN, saving bandwidth on the backbone network. ISM VLAN profiles allow users to bind/replace the predefined multicast registration information to subscriber ports quickly and easily.
IPv6 Ready 
The DES-1228/ME has been certified with the IPv6 Ready Logo Phase 2, which guarantees connectivity and manageability with an IPv6 network. Furthermore, it supports IPv4/v6 dual stack functions that allow the switch to act as a bridge between IPv4 and IPv6 networks. The DES-1228/ME supports standard management protocols such as SNMP, RMON, Telnet, SSH security authentication, and DHCP Relay Option 82.
Rich management capabilities
A web-based GUI provides a user-friendly interface and easy management, and DHCP auto-configuration gives administrators enhanced management features, allowing them to save configuration presets to a TFTP server. Individual switches can then boot their IP addresses from the server and load the preset configuration. Support for 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. Also, each port on these switches supports a Cable Diagnostic feature that helps detect cable related problems such as length or cable functionality issues.
