Managed L2+. Quality of Service (QoS) support. Basic switching RJ-45 Ethernet ports quantity: 24 Console port: RJ-45. 10G support. MAC address table: 16000 entries Switching capacity: 128 Gbit/s. Access Control List (ACL). Rack mounting. xStack L2+ Managed Stackable Gigabit Switches. The xStack DGS-3420 series of next generation Layer 2+ Gigabit switches delivers performance,. flexibility, security, multi-layer QoS, and accessibility, along with redundant power solutions for SMBs. and enterprises. With high Gigabit port densities, Gigabit SFP, 10-Gigabit SFP+ support, and advanced. software solutions, these switches can act as either departmental access layer devices or aggregation. switches to form a multilevel network structured with backbone and centralized high-speed servers.. Service providers can take advantage of the high SFP density switches (such as DGS-3420-28SC/26SC) to structure the aggregation of Fiber to the Building (FTTB). networks that are extended to the subscribers’ sites.. Unparalleled Flexibility. Easily deployed and simple to manage, the DGS-3420 can be stacked with any switch that supports D-Link’s Single IP Management to form a multi-level network structured with backbone and centralized high-speed servers. The virtual stack can include units located anywhere on the. same network domain, and uses optional 10-Gigabit uplinks to move intra-stack traffic at 20 Gbps full duplex speeds.. Redundant Ring Stacking. Alternatively, depending on whether linear or faulttolerant ring stacking is implemented, users can use one or two 10-Gigabit SFP+ ports to create a physical stack. 12 units or 576 Gigabit ports can be configured for a stack using direct attach cables to provide high bandwidth on the DGS-3420 Series with cost efficiency.. Security, Performance & Availability. The DGS-3420 Series provides a complete set of security features including L2/L3/L4 multi-layer Access Control Lists and 802.1X user authentication via TACACS+ and RADIUS servers.. Th
