Spanning Tree Protocol (STP, RSTP & MSTP) Emulation Software

The most comprehensive and scalable tool to verify the operation, performance, and scalability of spanning tree implementations; measure protocol reconvergence time during topology changes and determine the impact of link failures on QoS.

The N5580A N2X Spanning Tree Protocol Emulation Software offers the most comprehensive and scalable solution available for testing Spanning Tree protocols. These protocols are used to ensure loop-free layer-2 frame forwarding within Ethernet networks. N2X emulates carrier-scale topologies using the Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP), enabling the user to test legacy and next-generation switching devices with VLANs.

By emulating one or more of the Spanning Tree protocols, N2X can simulate complex LAN topologies and verify interoperability between protocol versions. N2X can also generate realistic traffic at the same time, to accurately verify the functionality and performance of Spanning Tree implementations.

Today’s Ethernet devices introduce QoS mechanisms for prioritizing real-time voice, video, and data traffic. Reconvergence of the Spanning Tree protocols following topology changes can adversely impact fairness and QoS – especially during oversubscribed network conditions. N2X enables thorough verification of traffic forwarding engines and QoS mechanisms while simulating Spanning Tree disruptions to validate device and network behavior.
