When aswitch of this kind operates as the upstream switch of H3C series switches runningMSTP, the upstream designated port fails to change their states rapidly.The rapid transition feature is developed on the H3C series switches to avoid this case.When a H3C series switch running MSTP is connected in the upstream direction to amanufacture's switch adopting proprietary spanning tree protocols, you can enable therapid transition feature on the ports of the H3C series switch operating as thedownstream switch. Among these ports, those operating as the root ports will then sendagreement packets to their upstream ports after they receive proposal packets from theupstream designated ports, instead of waiting for agreement packets from theupstream switch. This enables designated ports of the upstream switch to change theirstates rapidly.Related command: stp no-agreement-check.
