Description
Use the stp interface no-agreement-check command to enable the rapid transition feature on the
specified port.
Use the undo stp interface no-agreement-check command to disable the rapid transition feature on
the specified port.
The rapid transition feature is disabled on any port by default.
Some manufactures' switches adopt proprietary spanning tree protocols that are similar to RSTP in the
way to implement rapid transition on designated ports. When a switch of this kind operates as the
upstream switch of H3C series switches running MSTP, 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 an H3C
series switch running MSTP is connected in the upstream direction to a manufacture's switch adopting
proprietary spanning tree protocols, you can enable the rapid transition feature on the ports of the H3C
series switch operating as the downstream switch. Among these ports, those operating as the root ports
will then send agreement packets to their upstream ports after they receive proposal packets from the
upstream designated ports, instead of waiting for agreement packets from the upstream switch. This
enables designated ports of the upstream switch to change their states rapidly.
