The DGS-3420 xStack L2+ series is a new generation of switches that provide performance, flexibility, security and multi-layer QoS. DGS-3420-28TC switch is perfect for small and medium enterprises. With high Gigabit port density, support for Gigabit SFP, 10 Gigabit SFP+ and advanced software solutions, these switches can function either as department access layer devices or as aggregation switches, creating a multi-level network with a backbone structure and centralized high-speed servers.
The DGS-3420 switch can be stacked with any D-link Single IP switch, so the switch is easy to deploy and manage. The switch creates a multi-level network with a backbone structure, with centralized high-speed servers. The virtual stack can contain units anywhere in the same network domain, using the optional 10 Gigabit uplink links to transfer traffic inside the stack.
DGS-3420-28SC switch guarantees a complete set of security functions, including multilayer L2/L3/L4 access control lists and 802.1X user authentication via TACACS+ and RADIUS servers. The DGS-3420-28SC offers comprehensive VLAN support, including GVRP and 802.1Q VLAN to increase security and performance. The L2/L3/L4 QoS/CoS solution suite ensures that superior network akie services such as VoIP, ERP, Intranet and video conferencing are handled with the appropriate priority. The switch also uses the D-Link protection engine to prevent malicious flooding of network traffic caused by worms or viruses.
The DGS-3420-28TC switch offers comprehensive IPv6 support including IPv6, ICMPv6, DHCPv6, RIPng tunnel. With 10 Gigabit connectivity and IPv6 support, the switch allows you to secure your network for the future in terms of longevity - meeting the requirements of future IPv6 enabled network devices.
