upstream ports after they receive proposal packets from the upstream designated ports,

designated ports of the upstream switch to change their states rapidly.
1.7.2 Rapid Transition Configuration
I. Prerequisites
As shown in Figure 1-5, a Quidway series switch is connected to a partner's switch. The
former operates as the downstream switch, and the latter operates as the upstream
switch. The network operates normally.
The upstream switch is running a proprietary spanning tree protocol that is similar to
RSTP in the way to implement rapid transition on designated ports. Port 1 is a
designated port.
The downstream switch is running MSTP. Port 2 is the root port.
