IPv6 and IPv4 Routing The D-Link DCS-3620 Switch provides current IPv4 networks with a simple migration path to IPv6 and protects your investment for future network upgrades when greater security and larger addressing are required. Basic static routing such as RIP and RIPv2 are supported for small network routing applications. Advanced routing protocols such as OSPF and equal cost routing are supported for load balancing and building a scalable network. Stackable Up to 12 Units Each switch in the D-Link DCS-3620 Switch has four optional SFP+ Ports to install compatible modules for stacking provide up to 40Gbps data stacking backplane while in full-duplex mode. This enhances your overall network performance for switches transmitting large files such as graphics or pictures. Under stacking mode, the switches are hot-swappable. This means that in a stack configuration, any of the switches can be replaced or removed without affecting the network. There is no need to reconfigure a replacement switch; just give the new switch the same stack number ID as the old switch and the network will carry the same confi guration as before. This minimises network downtime and maximises the productivity of your business. Also, to facilitate network administration, cross stack port mirroring and port trunking are supported. The D-Link Safeguard Engine and Security The D-Link DCS-3620 Switch incorporates advanced mechanisms to detect an attack against the central processing unit of the switch and to take corrective action on the attacking interface. When a DoS attack is waged against any of the D-Link DCS-3620 Switches, the D-Link Safeguard Engine detects the threat and prevents overload of the CPU, thus ensuring network integrity and helping to maintain open network bandwidth channels. In addition, the D-Link DCS-3620 Switch offers a variety of authentication methods, including those without the requirement of a RADIUS server. It supports MAC-based Access Control, which authenticates the user based on the MAC address of the client so that authentication is transparent to the client. It also supports Web-based Access Control, which prompts for username and password before allowing access to TCP traffic. Lastly, the D-Link DCS-3620 Switch supports Network Access Protection (NAP). This feature works in conjunction with Microsoft software platforms such as Windows Vista to reinforce network health and security policies including policy validation, network restriction, remediation, and ongoing compliance. Voice and Video Applications For todays businesses, having voice, data, and video on the same network is common practice. This challenge is met by the D-Link DCS-3620 Switch, which supports 802.1p with eight queues. The administrator can designate traffic priority based on a variety of means including IP and MAC address, so that voice data is clear and jitter-free. Video traffic can also be assigned with the same priority. In addition, the D-Link DCS-3620 Switch provides IGMP Snooping, which allows the forwarding of multicast packets such as streaming audio and video without increasing network broadcast congestion. By snooping IGMP registration information within a frame, a list of workstations that have joined the multicast group is created. This list then allows the switch to intelligently forward packets to only the appropriate member workstations. For IPv6 traffic, the D-Link DCS-3620 Switch supports MLD snooping. Multicast routing is supported under independent multicast protocol, including PIM-SM, PIM-DM, and PIM-SDM (Sparse Dense Mode). DVMRP is also supported to interconnect two multicast-enabled networks across non-multicast networks. In conjunction with support for 802.1Q VLANs, Quality of Service (QoS) and security can be achieved on a network infused with data traffic. Standard and Enhanced Images The D-Link DCS-3620 Switch is embedded with two different software images, the Standard Image (SI) and the Enhanced Image (EI). The Standard Image provides fundamental features for usinesses such as switching, routing, multicasting, advanced Quality of Service (QoS), and robust security features. The Enhanced Image supports OAM, BGP, IPv6 dynamic routing, and tunneling which are all suitable for the service provider network Ease of Management The D-Link DCS-3620 Switch supports SNMP v1/2c/3 so traps can be set on abnormal events and information can be polled to maximise network productivity. Other standard management features also supported include RMON and IEEE 802.1D Spanning Tree. User interfaces include an intuitive Web-based GUI or standard CLI, either of which can be protected through SSL or SSH encryption.
