The DES-38xx series is a member of the D-Link xStack family of next generation switches that deliver performance, flexible expansion, robust security, multi-layer Quality of Service (QoS), Power Over Ethernet and redundant power option. The DES-38xx series forms a cost-effective Ethernet virtual stack for workgroup connection. It incorporates L3 packet routing and many functions typically found in a chassis-based solution. The DES-38xx series provides Single IP Management for seamless integration with a core Gigabit xStack attached to an optional high-speed 10Gigabit backbone.

 

Simple to deploy and easy to manage, the DES-38xx series comprises the departmental access-level devices that can be easily stacked and configured with any switches supporting D-Link's Single IP Management, including the D-Link xStack core switches, to form part of a multi-level network structured with backbone and centralized high-speed servers. Without any stacking cable, cable distance barrier and physical stacking method limitations, a DES-38xx stack can comprise of 32 units that are located anywhere on the same network domain, eliminating the possibility of any single point of failure. Ideal for deployment at the network edge, the DES-38xx blends L2 packet switching with dynamic L3 IP routing to relieve the network backbone and servers of any unnecessary traffic.

 

The DES-38xx series provides a complete set of security features for connectivity and access control, which includes L2/3/4 and Packet Content Access Control Lists (ACL), storm control and IP-MAC-Port Binding with DHCP Snooping. Authentication mechanisms such as 802.1x Guest VLAN, Web-based Access Control (WAC) and MAC-based Access Control (MAC) provide extra flexibility for user identity control. The DES-38xx also provides central management for administration access via TACACS+ and RADIUS. In addition, built-in Safeguard Engine protects DES-38xx against abnormal traffic

from virus or worm scanning. Together with network application control, this security ensures that not only proper user access is served, but malicious traffic is also prevented from being spread across the network.

 

The DES-38xx series provides extensive VLAN support including 4K VLAN entries, Q-in-Q, GARP/GVRP and 802.1v Protocol VLAN to enhance network security and performance. Bandwidth control allows users to set traffic limit for each port or flow to control the traffic volume from the edge of the network. The DES-3828, DES-3828P and DES-3852 support redundant power option to maximize network uptime. Other features include 802.3ad Link Aggregation, 802.1d Spanning Tree, 802.1w

Rapid Spanning Tree and 802.1s Multiple Spanning Tree and Loopback detection to increase network reliability and availability of a Virtual Stacking network structure.

 

The DES-38xx series implements a robust set of multilayer (L2, L3, L4) QoS/CoS features to ensure that critical network services like VoIP, ERP, Intranet and video conference are served with proper priority. 8 priority queues for 802.1p/TOS/DiffServ are supported, with classification and marking based on MAC SA/DA, IPv4/v6 SA/DA, DSCP, and/or TCP/UDP port numbers. With IP Multicast support, the DES-38xx is also ideal for high-bandwidth applications, such as MPEG video, delivering traffic to multiple receivers without adding any additional traffic burden to the network.
