D-Link DXS-3350SR network switch

D-Link's next-generation switches, DXS-3226GSR/DXS-3350SR are high port-density Layer 3 stackable switches that combine the ultimate performance with fault tolerance, security, management functions with flexibility and ease-of-use. All these features typically found in the more expensive chassis-based solutions, at the price of a stackable!

Fault Tolerant Star Stacking
Each D-Link DXS-3226GSR/DXS-3350SR switches are equipped with 2 stacking ports providing 20Gbps full duplex bandwidth. Up to 6 DXS-3226GSR/DXS-3350SR switches can be stacked, providing 120Gbps aggregated stacking bandwidth. Star stacking provides fault tolerance, and switch 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.

10G Uplinks 10 Times the Speed of Gigabit
D-Link DXS-3226GSR/DXS-3350SR provides the 10G uplinks for transmission at 10 times the speed of a Gigabit port. The 10G uplinks are available as optional modules each equipped with 2 XFP compliant slots, into which you can install 2 IEEE 802.3ae-compliant XFP transceivers for data transmission at 20,000Mbps in the full duplex mode.

Ring Stacking Topology
Shared 40Gbps stacking bandwidth in the ring topology is also provided for installation sites with fewer switches to stack. In a ring stacking scheme, DXS-3226GSR/DXS-3350SR supports up to 12 units per stack. No matter if the Star or Ring topology is employed, you can easily see the ID number of the stacked units from the 7-segment display on the front panel of each switch.

Complete Solution for Mid-Sized Businesses & Enterprises
Whether you need to bring Gigabit or just conventional 10/100Mbps speed to your organization's desktops, D-Link DXS-3226GSR/DXS-3350SR has the right solution with right port types, port densities and uplinks to match your requirements. With scalability and flexibility built in, individual 10/100Mbps Ethernet and 10/100/1000Mbps Gigabit units may be joined in any combination to evolve with your network needs.

High Gigabit Port-Density
D-Link's DXS-3226GSR/DXS-3350SR provides up to 28 Gigabit ports per switch in a low-profile 1-U rack-mount case. This gives you up to 312 Gigabit ports per stack in the star architecture, or maximum 336 Gigabit ports per stack in the ring topology. This high Gigabit port density allows your DXS-3226GSR/DXS-3350SR to be deployed either as a core switch or as an easily expandable stack for Gigabitto-the-desktop applications.

Wire-speed Packet Routing
D-Link DXS-3226GSR/DXS-3350SR provides wire-speed non-blocking switch fabrics with very fast hardware-based packet filtering/forwarding and instant support for Windows, Unix and Internet environments. Packet routing supports RIP v.1, v.2, OSPF and DVMRP protocols, performed by on-board ASICs at speeds many times faster than CPU-based routers.

Plug-and-Play Configuration
The DXS-3226GSR/DXS-3350SR simplifies and speeds up your management tasks, as 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 comprehensive management and configuration tasks, eliminating the need for you to install expensive, complex SNMP network management software.

Enhanced Network Performance & Availability
D-Link's DXS-3226GSR/DXS-3350SR provides extensive VLAN support including 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 DXS-3226GSR/DXS-3350SR supports redundant power option to maximize network uptime. Other features include 802.3ad Link Aggregation, 802.1d Spanning Tree and 802.1w Rapid Spanning Tree to increase network reliability and availability of your stack.

Easy Expansion Beyond Your DXS-3226GSR/DXS-3350SR
With D-Link SIM (Single IP Management) support*, you can easily add up to 32 switch units per stack outside of your DXS-3226GSR/DXS-3350SR that are not limited to any specific models. Through the built-in web manager, you can have a Tree View with clear information about the members of the stacks, and your Network Topology that shows the locations of the stacked units and their link information. Your DXS-3226GSR/DXS-3350SR's support for any switch models with embedded Single IP Management means that you can expand your stack to include also L2 access-level or any other switches to accommodate your network growth.

Multi-layer Quality of Service (QoS)
The DXS-3226GSR/DXS-3350SR 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) Support
D-Link DXS-3226GSR/DXS-3350SR supports the Virtual Router Redundancy Protocol (VRRP), allowing 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.

Comprehensive Security
D-Link's DXS-3226GSR/DXS-3350SR provides a complete set of security features 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 DXS-3226GSR/DXS-3350SR 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.

Extensive Network Management Functions
The DXS-3226GSR/DXS-3350SR supports a variety of network management options including: console CLI, Telnet configuration, web-based and SNMP v.1, v.2c, v.3 management, RMON monitoring, TFTP firmware upgrade, Port Mirroring for troubleshooting, Bootp and DHCP IP assignment. The DXS-3226GSR/DXS-3350SR also supports a variety of advanced traffic management options including: 802.1x, Bandwidth Control, Broadcast Storm Prevention, and support for IGMP v.1, v.2 snooping.
