Parameter
interface-type: Port type.
interface-number: Port number.
Description
Use the stp interface no-agreement-check command to enable rapid transition for a
specified port.
Use the undo stp interface no-agreement-check command to disable rapid transition
on a port.
Rapid transition is disabled on a port by default.
As switches of certain manufacturers coming with some proprietary protocols
concerning STP employed, the way to implement rapid transition on the designated
ports of this kind of switches is similar to that of RSTP. So, when a switch of this kind
operates as the upstream switch with Quidway series switches running MSTP
connected to it, the upstream designated port fails to change their state rapidly.
Rapid transition is developed for Quidway series switches to avoid this. When Quidway
series switches with MSTP employed are connected to switches of certain
manufacturers, you can enable rapid transition on the ports of the Quidway series
switches operating as the downstream switches. 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 rather than wait for the
agreement packets sourced from the upstream switch. This enables designated ports
of the upstream switch to change their states rapidly.
