Description
Use the stp no-agreement-check command to enable the rapid transition feature on a port.
Use the stp no-agreement-check command to disable the rapid transition feature.
By default, the rapid transition feature is disabled on a port.
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 an H3C series switch running MSTP, the upstream designated port fails to change
their states rapidly.
The rapid transition feature aims to resolve this problem. When an H3C series switch running MSTP is
connected in the upstream direction to another 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 actively 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.
Related commands: stp interface no-agreement-check.
The rapid transition feature can be enabled on only root ports or alternate ports.
You can enable the rapid transition feature on the designated port. However, the feature does not
take effect on the port.
