Operation Manual – RPR H3C S9500 Series Routing Switches Chapter 1 RPR Configuration TP fast timer: defines the fast interval at which TP frames are sent. A TP fast timer starts when a station starts initializing or detects a topology change. After sending nine TP frames at fast intervals, the station begins to send TP frames at slow intervals. -

Operation Manual – RPR H3C S9500 Series Routing Switches Chapter 1 RPR Configuration Class A is further divided into subclass A0 and subclass A1. RPR can reserve bandwidth for the subclass A0 service. When congestion occurs, the unused reserved bandwidth cannot be used by lower priority services. For the subclass A1 service, rate limiting is used. -
