D-Link 8-Port 100BaseFX (SC-Duplex) DES-6305 User Manual

Multi-layer Chassis Switch

DES-6300

Office LAN

Using standard-based routing, the DES-6300 provides instant support 
for Windows, NetWare, Unix, AppleTalk and Internet environments. 
Built-in wire-speed non-blocking switch fabric provides hardware-
based packet filtering/forwarding. Packet routing is performed by on-
board ASICs, which is many times faster than traditional CPU-based 
routers.  

The DES-6300 can be instantly integrated into any existing network 
for seamless integration of multi-layer packet switching. With multi-
layer support for every port, you can flexibly segment the network into 
domains and sub-domains, using (1) subnet, user and server IDs to 
route traffic, and (2) custom filters based on users' physical MAC 
addresses to filter extraneous traffic. At Layer 2, the switch uses auto-
learned and user-defined MAC addresses to discard and forward 
packets. At higher layers, it looks at the routing table to route packets 
to their destinations.

With a modularized design and a wide range of port selection from 
Ethernet/Fast Ethernet to twisted-pair and fiber Gigabit, this switch 
provides for easy, scalable expansion. Bandwidth migration is simple 
with 10/100/1000Mbps multi-speed support and module hot swapping 
capability. This architecture provides for great flexibility and 
investment protection.

You can configure the switch with up to 96 10/100Mbps Fast Ethernet 
ports, 72 100Mbps fiber ports, 12 Gigabit ports, or a combination of 
these. Copper and fiber Gigabit ports (SX, LX and GBIC included) are 
provided. This flexible configuration allows you to install Fast 
Ethernet for workstation connections, copper Gigabit for departmental 
server connections, and fiber Gigabit for backbone/campus 
attachments.

The switch provides the capability to operate with an optional 
redundant power supply. This gives you the added reliability against 
power interruption risks and is important for mission-critical 
applications. The switch comes standard with a single power supply. 
For campus/enterprise application, you can opt to install dual power 
supplies.

When operating at Layer 2, you can set up VLANs for different ports
or users to set broadcast domains and segment network traffic to 
manage available bandwidths and enhance network security.

You can combine up to 8 Fast Ethernet ports on the same module 
into a trunk to create a 1600Mbps full duplex aggregated bandwidth 
to connect to a server or to another switch. 2 Gigabit ports from the 
same module can be combined into to create a 4000Mbps trunk. Port 
trunking supports load-sharing and redundant backup links, and is 
useful for switch-to-switch cascading or server connection.

With Quality of Service based on multi-layer information, your 
workstations and server can be attached to the switch and run delay-
sensitive applications like video-conference and IP telephony based 
on traffic prioritization and queuing mechanism.

The switch listens to IGMP (Internet Group Management Protocol) 
messages to build mapping table and associate forwarding filters. It 
uses GMRP (GARP Multicast Registration Protocol) to dynamically 
configure the switch ports to forward IP multicast traffic only to 
those ports associated with multicast hosts. 

This capability allows you to mirror adjacent ports for the purpose of 
analyzing incoming and outgoing packets where packets can be 
studied.
