MODEL- DXS-3326GSR        VENDOR- D-LINK
  
FEATURES- DXS3326GSR-DLINK - X Stack Stackable, rack-mount Switch
       Managed Stackable Multilayer Switch- (24) Gigabit SFP Fiber Slots 
        with (4) Combo 10/100/1000 Ports, (2) 10-Gig Stacking Ports, and 
        (2) Optional 10-Gig Uplinks. Includes DEM-CB50 50cm 10-Gig stacking 
        cable.
       D-Links xStack Series is a set of "Next Generation" high 
        performance stackable switches that deliver high scalability, wire-
        speed Gigabit performance, high availability, integrated 10-Gigabit 
        stacking, redundant power option, and support for stacking in a 
        "ring" or "star" topology (requires DGS-3324SRi). xStack Switches 
        can stack up to 12 units in a stack, providing up to 384 Gigabit 
        ports, and up to 40Gbps of shared stacking bandwidth in a ring 
        topology or 20Gbps of dedicated stacking bandwidth in a "star" 
        topology. The xStack DXS-3326GSR is designed to meet the most 
        demanding high port density fiber requirements. Each unit provides 
        24 Gigabit fiber slots with (4) 10/100/1000 Combo ports, and 
        switching capacity of 128Gbps. It stacks with the other xStack
        Switches including the DGS-3324SR, DGS-3324SRi, and DXS-3350SR to 
        provide unprecedented flexibility in a switch stack environment.
* HIGH AVAILABILITY
   The xStack DXS-3326GSR stacked in a ring topology supports "Shortest-
   Path, Fail-Safe" switching which improves resiliency, uptime, and 
   network efficiency. It also supports an optional Redundant Power Supply 
   (DPS-500) and includes support for 802.3ad Link Aggregation, 802.1d 
   Spanning Tree, 802.1w Rapid Spanning Tree, and 802.1s Multiple Spanning 
   Tree for increased network reliability and availability.
* NETWORK MANAGEMENT
   An extensive set of network management features is provided including 
   console CLI, Telnet, Web, SNMPv1/v2/v3, RMON, TFTP, Port Mirroring, 
   BootP, and DHCP. The switch can also be easily managed using D-Link s 
   SIM (Single IP Management) Clustering technology. It also supports a 
   variety of advanced traffic management options including 802.1x, 
   Bandwidth Control, Broadcast Rate Limiting, and support for IGMP 
   Snooping v1/v2/v3.
* ADVANCED ENTERPRISE FEATURES
   A robust and consistent set of QoS/CoS, VLAN, and security features is 
   provided. They include 8 priority queues for 802.1p/ToS/DiffServ, with 
   classification and marking based on MAC SA/DA, IP SA/DA, and/or TCP/UDP 
   port numbers. Layer 3 dynamic routing protocols include RIPv1/v2, 
   OSPFv2, PIM-DM/SM, DVMRP, and VRRP. Security features include 802.1x   
   Port-based Authentication), 802.1x (MAC-based Authentication), and 
   Access Control Lists (ACL) based on MAC address, IP address, and/or 
   TCP/UDP port numbers. It also provides extensive support for GARP/GVRP, 
   802.1q, 802.1v IPv6 VLAN, and port-based VLANs for up to 255 static 
   groups per device.
   The xStack DXS-3326GSR is the latest example of D-Links continued 
   commitment to our channel partners and customers to be the industry 
   leader in delivering cost-effective, reliable, high performance, 
   feature-rich switch solutions.
