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.

Included Highlights

Advanced IP and Ethernet

Tellabs ESU2 allows for the efficient delivery of modern enterprise services and applications (both IPv4 and IPv6), including the management of subtended powered devices like VoIP phones, Wi-Fi WAPs and IP cameras. Quality of Service (QoS) is provided through traffic segmentation, traffic classification, rate limiting (shaping), queue management (buffering) and scheduling (policing).


Tellabs ESU2 offers high availability via Link Aggregation (LAG) and Rapid Spanning Tree Protocol (RSTP) for dual homing to core routers.


Tellabs ESU2 advanced security is maintained through the regimented support of Network Access Control (NAC), IEEE 802.1x, RADIUS, MAC Authentication Bypass (MAB), Dynamic ARP Inspection (DAI) and DHCP. Additional security functions include Access Control List (ACLs) implemented at Layer-2, Layer-3 and Layer-4 triggers.


Tellabs ESU2 comes equipped with four Gigabit Ethernet and two 10 Gigabit Ethernet network uplink interfaces. These 1 GbE and 10 GbE ports are integral to the Ethernet switching fabric, common control and timing mechanism of the Tellabs OLTs.
