IPv 6 & IPv 4 Routing The D-Link DCS-3620 Switch provides current IPv 4 networks with a simple migration path to IPv 6 & protects your investment for future network upgrades when greater security & larger addressing are required. Basic static routing such as RIP & RIPv 2 are supported for small network routing applications. Advanced routing protocols such as OSPF & equal cost routing are supported for load balancing & 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 40 Gbps 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 & the network will carry the same confi guration as before. This minimises network downtime & maximises the productivity of your business. Also, to facilitate network administration, cross stack port mirroring & port trunking are supported. The D-Link Safeguard Engine & Security The D-Link DCS-3620 Switch incorporates advanced mechanisms to detect an attack against the central processing unit of the switch & to take corrective action on the attacking interface. When a Do S attack is waged against any of the D-Link DCS-3620 Switches, the D-Link Safeguard Engine detects the threat & prevents overload of the CPU, thus ensuring network integrity & 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 & 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 & security policies including policy validation, network restriction, remediation, & ongoing compliance. Voice & Video Applications For todays businesses, having voice, data, & 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 & MAC address, so that voice data is clear & 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 & 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 IPv 6 traffic, the D-Link DCS-3620 Switch supports MLD snooping. Multicast routing is supported under independent multicast protocol, including PIM-SM, PIM-DM, & 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 (Qo S) & security can be achieved on a network infused with data traffic. Standard & Enhanced Images The D-Link DCS-3620 Switch is embedded with two different software images, the Standard Image (SI) & the Enhanced Image (EI).
