24-Port 10/100/1000 Switch + 4 combo SFP, 10Gig Stacking
Where to buy


The D-Link xStack Layer 3 Gigabit switches are stackable switches that combine performance with physical star stacking fault tolerance, robust security, quality of service (QoS), versatile management functions with scalable flexibility. All these features typically found in the more expensive chassis-based solutions, at the price of a stackable. A stack can provide up to 312 Gigabit ports * in the star architecture, and 336 Gigabit ports ** for the ring topology. 10Gigabit uplinks are available as optional modules, each with 2 XFP slots for transceivers capable of transmission at 20,000Mbps in the full duplex mode.

High-Speed Stacking. Each switch is equipped with 2 stacking ports providing 20Gbps full duplex bandwidth. Up to 6 units can be stacked with a Stacking Master, itself equipped with 6 stacking ports providing 120Gbps aggregated stacking bandwidth. Star stacking provides fault tolerance, as units can be added or removed without interrupting the service of the entire stack. The switches are stacked together through high-speed stack cables, allowing the entire stack to operate as a single high-performance entity. Alternatively, for installation sites with fewer switches to stack, shared 40Gbps ring stacking topology can be employed, so you don't have to add a Stacking Master.

Easy Expansion Beyond Physical Stack. With D-Link Single IP Management support, you can easily add up to 32 switch units per stack (not limited to any specific models) outside of your physical stack. Multiple switches can be configured, monitored and maintained from any workstation running a web browser through one single IP address. The stack is managed as a single object, and all stacked units are identified by a single IP address. A simple yet powerful web-based interface allows you to perform most management and configuration tasks, eliminating the need for you to install expensive, complex SNMP network management software.

Comprehensive Security.
A complete set of security features is provided for connectivity and access control. This set includes Access Control Lists (ACLs) based on MAC address, switch port, IP address, and/or TCP/UDP port numbers, 802.1x user authentication and MAC address control. The xStack also provides central management for administration access via TACACS/TACACS+ and RADIUS. Together with network application control, this security ensures that not only proper user access is served, but malicious traffic is also prevented from being spread across the network. VLAN support includes GARP/GVRP and 802.1Q to enhance network security and performance. Bandwidth control allows you to set traffic limit for each port to control the traffic volume from the edge of the network. The switch implements a robust set of multi-layer (L2, L3, L4) QoS/CoS features to ensure that critical network services like VoIP , ERP, Intranet and video conference are served with proper priority. Up to 8 priority queues for 802.1p/TOS/DiffServ are supported, with classification and marking based on MAC SA/DA, IP SA/DA, and/or TCP/UDP port numbers. Virtual Router Redundancy Protocol (VRRP) allows several L3 switches on a multi-access link to utilize the same virtual IP address. One switch will be elected as a master with the other switches acting as backups in case of the failure of the master router. This VRRP support provides convenience, permitting your host system to be configured manually or via DHCP with a single default gateway.
