Department Security and QoS Switch
With its 12.8 Gigabits per second and non-blocking switch fabric, the 
WGS3-2820 can easily provide a local, high bandwidth, and Gigabit 
Ethernet network for backbone of your department. With the two 
SFP ports, the WGS3-2820 provides the uplink to the backbone 
network through Gigabit Ethernet LX/SX SFP modules. With the 
security and QoS features, it improves the network efficiency and 
protects the network clients.
ISP / Telecom Backbone Routing Switch
With build-in robust Layer 3 IP and Multicast routing protocols, the 
WGS3-2820 ensures reliable routing between VLANs and network 
segmentation. The routing protocols can be applied by per-port or 
VLAN interface with up to 2K routing entries, and the high-density 
routing interfaces provide expandability to meet the growing needs of 
networks. Moreover, with the hot VLAN feature,Q-in-Q (VLAN 
stacking) supported, it allows the service providers to offer certain 
services, such as Internet access on specific VLANs for specific 
customers, and it still allows them to provide other types of services 
for their other customers on other VLANs.
