Spanning Tree Protocol (STP) is a mechanism which provides loop-free paths within a pure layer 2 topology. STP allows for link redundancy by temporarily blocking ports in order to have a single path. Upon the detection of a link, or port failure, STP will re-converge to leverage the other unused port. This prevents broadcast storms and the duplication of packets from floating around in the network endlessly. There are multiple flavors of STP, each with their own features and nuances, which includes: Per VLAN Spanning Tree Protocol Plus (PVST+), Rapid Per VLAN Spanning Tree Protocol Plus (Rapid PVST+), and Multiple Spanning Tree Protocol (MSTP).
With LiveAction 2.6 and greater, users have higher levels of situational awareness and visibility on their switched network infrastructure by providing a topological representation of each Spanning Tree instance, as well as providing alerts on the transitioning port state events. This helps network administrators to act quickly and identify the insertion of rogue and/or misconfigured switches promptly. Similarly, the STP path representation can be used to identify suboptimal layer 2 paths in a switched network. This application note provides instructions on enabling the STP functionality within LiveAction and will cover the aforementioned use case.
