24-Port Layer 2 Fast Ethernet Stackable Switch - D-Link

24-Port Layer 2 Fast Ethernet Stackable Switch - D-Link
10/100Mbps L2 Stackable Switch
DES-3226S
DES-3226S with 24 10/100Mbps ports.
A DES-332GS stack module installed in the
open slot provides a GBIC port and switch
stacking capability.
24-Port Layer 2 Fast Ethernet Stackable Switch
The DES-3226S is a Stackable 10/100Mbps Layer 2 Switch designed for departmental connection. It provides 24 10/100Mbps
ports, 1 GBIC port for server or fiber backbone connection, and scalable expansion through switch stacking of up to 8 units.
Advanced features such as port trunking, VLANs and priority queues are also provided, allowing a department to
effectively deploy a bottleneck-free switching network for easy integration with a larger enterprise or campus network.
24 10/100Mbps Ports for Workstation Connection
The switch provides 24 10/100Mbps ports supporting autosensing and auto-negotiation of network speeds and full/half
duplex. These ports can connect to workstations and print
servers, giving each a dedicated bandwidth. All ports
support auto MDI-II/MDI-X uplink, allowing you to connect
to workstations, servers, or other switches from any port
without the need to change your usual straight-through
twisted-pair cables.
Port Trunks for Aggregated Bandwidths
With low cost per port, port trunking provides an easy and
economical alternative solution for server connection to
attain Gigabit bandwidth. Up to 8 10/100Mbps ports or 8
Gigabit ports can be combined together to create a multi-link
load-sharing aggregated bandwidth to a server. Trunked ports
can span multiple units of the stack for fail-safe connectivity
to mission-critical servers and the network center. Up to 8
multi-link trunks can be configured for a stack.
Switch Stacking & GBIC Port
The switch provides an open slot for installation of a
stack module, which is equipped with a stacking port and a
GBIC port. The stacking port is for switch stacking. The
GBIC port provides for flexible deployment of multi-mode
or extended cable-length single-mode fiber. At 2000Mbps
full duplex, this port gives you Gigabit server connection or
attachment to a fiber backbone.
VLANs for Enhanced Security & Performance
VLANs improve security and bandwidth utilization by
limiting the broadcast domains and confining intra-group
traffic within their segments. To segment up the network,
workstations supporting IEEE 802.1Q VLAN Tagging
connected to the switch can be grouped into different Virtual
LANs (VLANs). The switch also supports GVRP (GARP
VLAN Registration Protocol) for automatic VLAN
configuration distribution.
Scalable Expansion
Up to 8 DES-3226S can be stacked together. You can add
units to reach maximum 192 10/100Mbps ports and 8 GBIC
ports per stack. The switches are stacked together through
high-speed stack cables that provide gigabit per second
backplane, allowing the entire stack to perform as a single
entity.
Flow Control to Prevent Packet Loss
The switch supports standard IEEE 802.3x Flow Control.
Working in conjunction with buffer overrun auto-detection,
this full-duplex data transfer mode provides protection
against possible data loss for 802.3x supported servers
directly connected to the switch.
Advanced Network Access Management
802.1x feature enables user authentication for each network
access attempt. Port Security features allow you to limit the
number of MAC addresses per port in order to control the
number of stations for each port. Static MAC addresses can
be defined for each port to ensure only registered machines
are allowed to access. By enabling both of these features, you
can establish an access mechanism based on user and
machine identities, as well as control the number of access
stations.
DES-3226S
Product Description
Multi-layer Access Control List (ACL)
Access Control List (ACL) allows the network administrator
to define the policies on network traffic control. The DES3226S supports comprehensive and multi-layer ACLs,
providing a powerful tool for network management. For
example, the DES-3226S can be set to block malicious bulk
traffic from a specific client (based on either MAC or IP
address), or during a virus attack. The DES-3226S can be set
to restrict its flooding based on a virus' unique pattern
(TCP/UCP port number).
Advanced Qos Support
DES-3226S supports not only Layer2 802.1p Priority Queue
control, but also a variety of ways to prioritize network
packets. Milti-layer information from L2 to L4 can be used
to classify packet priorities. This function support allows
you to attach IP telephony devices or video servers to the
switch to run delay-sensitive applications like video
conference and voice over IP.
Flexible Transmission Scheduling
The switch supports 2 methods of packet transmission
scheduling: Strict Round-Robin (SRR) and Weighted
Round-Robin (WRR). You can select to use SRR to strictly
enforce your priority queues, or WRR to address bandwidth
limitations at peak time. WRR allows each queue to be
assigned a different percentage of the output port's
bandwidth, so that lower-priority queues are not denied
access to buffer space and port bandwidth.
IGMP Snooping for Broadcast Control
The switch listens to IGMP (Internet Group Management
Protocol) messages to build mapping table and associate
forwarding filters. It dynamically configures the switch ports
to forward IP multicast traffic only to those ports associated
with multicast hosts.
Broadcast Storm Control
To limit too many broadcast/multicast flooding in the
network, broadcast/multicast storm control is configured to
screen excessive traffic. Packets are discarded if the
respective count exceeds the configured upper threshold in a
given time interval. The possible range of upper threshold is
from 0 to 255k packets per second.
10/100Mbps L2 Stackable Switch
802.1D & 802.1w Rapid Spanning Tree
For mission critical environments with multiple switches
supporting STP, you can configure the stack of switches
with a redundant backup bridge path, so transmission and
reception of packets can be guaranteed in event of any
fail-over switch on the network.
Multiple Management Interfaces
SNMP v.1, v.2c, v.3 network management is supported,
using the built-in MIBs. RMON monitoring and SYSLOG
are provided for effective central management. The switch
also provides a Command Line Interface (CLI) and a Webbased GUI. CLI enables quick system configuration for
administrators familiar with command line operation. The
embedded Web-based interface allows you to easily access
the switch from anywhere on the network and trouble
shoot it in real-time. You can, for example, browse the
MAC address table via the Web browser and perform
searching to identify the location of any workstation. Port
utilization graphs provide real-time traffic monitoring and
diagnostic information.
Optional Ports (Stand-alone Configuration)
If you configure the DES-3226S as a stand-alone switch,
you can install the following modules in the open slot:
- 2-port Fast Ethernet module (10/100BASE-TX)
- 1 or 2-port Fast Ethernet multi-mode fiber module
(100BASE-FX)
- 1 or 2-port Fast Ethernet single-mode Fiber module
(100BASE-FX)
- 2-port Gigabit fiber module (1000BASE-SX)
- 2-port Gigabit fiber module (1000BASE-LX)
- 2-port Gigabit copper module (1000BASE-T)
- GBIC module (2 ports)
Gigabit Over Copper Twisted-pair
The optional Gigabit copper ports provide an inexpensive
alternative solution to the fiber. Using your existing lowcost Cat. 5 twisted-pair wires as the transmission media,
these ports allow you to instantly upgrade your servers to
Gigabit capability without requiring you to install new,
expensive fiber cables.
Port Mirroring
This function allows you to mirror adjacent ports for the
purpose of analyzing incoming and outgoing packets where
packet patterns can be studied.
