DGS-3620 Series
xStack L3 Managed Stackable Gigabit Switches
IPv6 and IPv4 Routing
The xStack DGS-3620 Series provides current IPv4 networks with a simple migra-
tion 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 xStack DGS-3620 Series has four 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 trans-
mitting 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 recon-
figure a replacement switch; just give the new switch the same stack number ID
as the old switch and the network will carry the same configuration as before. This
minimizes network downtime and maximizes the productivity of your business.
Also, to facilitate network administration, cross stack port mirroring and port trunk-
ing are supported.
The D-Link Safeguard Engine and Security
The DGS-3620 Series 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 DGS-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 xStack DGS-3620 Series 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 cli-
ent 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 xStack Series supports Network Access Protection (NAP).
This feature works in conjunction with Microsoft® software platforms to reinforce
network health and security policies including policy validation, network restriction,
remediation, and ongoing compliance.
Voice and Video Applications
For today’s businesses, having voice, data, and video on the same network is
common practice. This challenge is met by the xStack DGS-3620 Series, which
support 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 xStack DGS-3620 Series 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 xStack DGS-3620 Series 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.
Ease of Management
The xStack DGS-3620 Series supports SNMP v1/2c/3 so traps can be set on abnormal
events and information can be polled to maximize 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.
