24-Port Rackmount Managed Switch

DES-3026

KEY FEATURES
24 10/100 BASE-TX Ports with 2 Open Slots 8.8 Gbps Switching Capacity VLANS (Upto 255) Network Management using Web GUI, CLI, SNMP, Telnet Virtual Stack of upto 32 units using D-Link SIM 802.1x Port & MAC based Access Control
Ideal solution for workgroups and departments
Part of the DES-3000 series, the DES-3026 is a highperformance managed Layer 2 switch that provides an ideal solution for workgroups and departments. Originally designed as an entry-level management solution for the SMB, these switches have evolved into more advanced devices with many added functions. Businesses looking for an advanced yet affordable solution can deploy these switches to manage their desktops. In addition to offering many versatile software functions, these switches also provide fiber uplinks to connect together small groups of users such as in different classrooms or departments spread across on a campus or between buildings. Features and Benefits: Advanced Enterprise Features: The DES-3026 includes many features not found in other switches of the same class, such as IP-MAC-port binding user access screening, traffic segmentation and up to 255VLAN (802.1Q). In addition, it also supports 802.1x port-based/ MAC-based access control, and external RADIUS server user authentication. To prevent hackers from overwhelming the switch with unnecessary workload, the DES-3010 provides the CPU Interface Filtering function to filter out vicious packets before they reach the CPU. For Quality of Service, it supports 802.1p Priority Queues and packet classification based on TOS, DSCP and MAC DA. ment configuration. Bandwidth Control: Network administrators can define throughput levels for each port to manage bandwidth. The bandwidth limiting feature provides fine granularity with the ability to define limits down to 64Kbps segments. When applied to control of broadcast storms infected with virus, this feature can limit the level of damage a virus attack can do to the network. The switch provides IGMP snooping to control multicast transmission, and port mirroring to facilitate diagnostics. Versatile Management Support: The DES-3026 supports standard-based management protocols such as SNMP, RMON, BOOTP, Telnet and webbased HTTP. With DHCP auto-configuration, the administrator can pre-set configurations and save them in a TFTP server, and individual switches can boot their IP from the server and load in the pre-set configurations. Virtual Stacking: With D-Link Single IP Management support, the DES-3026 simplifies and speeds up management tasks. Multiple switches can be configured, monitored and maintained from any workstation running a web browser through one unique IP address. The stack is managed as a single object, with all units identified by a single IP address. Administrators can see a Tree View of the members of the stack and a network topology showing the locations of the units and their link information. This simple yet powerful web-based management eliminates the need to install expensive SNMP network management software. Up to 32 units can be added to a stack without limitation to any specific switch models.

Enhanced Network Resilience: To enhance network resilience, the DES-3026 provides 802.1D Spanning Tree/802.1w Rapid Spanning Tree, STP loopback detection, and broadcast storm control. It provides 802.3ad Link Aggregation port trunks for load sharing/ redundancy backup in a switch cascading or server attach-
