Overview

The latest generation of D-Link® xStack® Switches supports IPv6 routing and has more

advanced features than ever to address today’s security, QoS, and management concerns.

The xStack DGS-3620 Series includes ve Gigabit managed switches with a choice of 24 or

48 port 10/100/1000Base-T models, 24 SFP port model, and PoE+ model options. The DGS-

3620-28TC comes with four combo SFP slots and four 10-Gigabit SFP+ slots. The DGS-3620-

28SC is the ber version equipped with four combo 10/100/1000 Base-T ports and four

10-Gigabit SFP+ slots. The DGS-3620-52T has four 10-Gigabit SFP+ slots. The DGS-3620-28PC

and DGS-3620-52P also include PoE (802.3af) and PoE+ (802.3at) that provides up to 30W to

power devices such as IP phones, Access Points, or security cameras.

The xStack DGS-3620 Series is equipped with robust features that fulll the most demanding

network’s needs for voice and video streaming. Stackable up to 12 units under a single IP,

the switches are able to provide a total of up to 576 Gbps aggregated bandwidth. To help

secure your network, the D-Link Safeguard Engine™ helps prevent Denial-of-Service (DoS)

attacks while the Access Control List (ACL) enhances network security. The DGS-3620 Series

is equipped with industry standard management features including easy-to-use CLI and

web-based administrator interfaces. D-Link provides these features on a scalable platform,

increasing your company’s productivity while protecting your investment.

IPv6 and IPv4 Routing

The xStack DGS-3620 Series 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 xStack DGS-3620 Series has four SFP+ Ports to install compatible
modules for stacking provide up to 40Gbps data stacking backplane while in full­duplex mode. This enhances your overall network performance for switches trans­mitting large les such as graphics or pictures. Under stacking mode, the switches
are hot-swappable. This means that in a stack conguration, any of the switches can
be replaced or removed without aecting the network. There is no need to recon­gure a replacement switch; just give the new switch the same stack number ID
as the old switch and the network will carry the same conguration 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.

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 trac priority
based on a variety of means including IP and MAC address, so that voice data is clear
and jitter-free. Video trac 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 trac, 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 trac.

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.

In addition, the xStack DGS-3620 Series oers 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 trac. 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.
