Wire-speed IP Packet Routing
Using standard-based routing, the DGS-3308TG provides instant support for Windows, Unix 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 DGS-3308TG can be instantly integrated into any existing network for seamless integration of Layer 2 and Layer 3 packet switching. With Layer 2 and Layer 3 support for every port, you can flexibly segment the network into domains and sub-domains, using (1) subnet IDs and user IP numbers 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 Layer 3, it looks at the user-specified routing table to route packets to their destinations.
6 Gigabit Ports Over Existing Twisted-pair Cables
The DGS-3308TG provides 6 1000BASE-T copper Gigabit ports with full/half-duplex support. These ports transmit data at 1000Mbps over your existing Cat. 5 twisted-pair network cable, avoiding for you to the need to install expensive fiber cables. These ports, furthermore, support auto-sensing 10/100/1000Mbps speeds, allowing you to integrate with your existing Ethernet network then instantly upgrade to Gigabit anytime later.
2 GBIC Fiber Ports
For flexible fiber connection, 2 GBIC ports are provided for installation of 1000BASE-SX short/medium-distance and 1000BASE-LX long-distance fiber. An optional PHY module must be inserted in each of these ports.
Maximum Network Uptime
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.
VLANs for Performance & Security
When operating at Layer 2, you can set up VLANs for different ports to set broadcast domains and segment network traffic to manage available bandwidths and enhance network security.
Port Trunks for Bandwidth Aggregation
The Gigabit ports can be combined together to create a multi-link load-sharing trunk. Up to 4 Gigabit ports can be set up per trunk. The switch supports up to 4 port trunks. Port trunks are useful for switch-to-switch cascading, providing very high full-duplex speeds.
Quality of Service (QoS)
Built-in IEEE 802.1P Priority Queues capability allows your workstations and server to attach to the switch and run delay-sensitive applications like video-conference and IP telephony based on traffic prioritization and queuing mechanism.
IP Multicast (IGMP snooping)
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.
