Ethernet Switching Unit Two (ESU2)
The ESU2 is engineered to support most critical enterprise business services and applications in the private sector, government, hospitality, healthcare and education markets. It supports higher-level IP functionality (both IPv4 and IPv6) with full IEEE protocol support, including efficient user-to-user and machine-to-machine communication with Ethernet Bridging and powerful VLAN architecture that supports a converged network (voice, data, video, and any device with an IP address). In addition, Layer-2 through Layer-4 Access Control Lists (ACL) for enterprise network security and full IEEE 802.1x are supported. Quality of Service (QoS) is supported at the port level to provide required traffic segmentation/classification, rate limiting (shaping), queue management (buffering) and scheduling (policing) mechanisms.
