WebWhat's the minimum possible "hello time" for Rapid Spanning Tree (RSTP)? Per standard, the range is 1-10 seconds, with a recommended default of 2 seconds. Is the minimum dictated by the RSTP standard, or would it be switch-dependent? Min/Max ranges are dictated per standard, but the default value is recommended (as mentioned above). WebThis Technical Note explains network redundancy concepts and gives general direction on configuring Multiple Spanning Tree Protocol (MSTP) to make the most effective and efficient use of redundant link between switches. ... RSTP is enabled and the port cost (based on speed) is enough to make the right thing happen. RSTP .

WebHigh-Availability Seamless Redundancy Switches decide how to forward communications based on an algorithm that converges to a tree topology by designating or blocking links. Performance is very topology-dependent, and healing calculations don’t start until a failure happens.
