Usage guidelines
When a port on an MSTP, RSTP, or PVST device connects to an STP device and receives STP
BPDUs, the port automatically transits to the STP mode. However, the port cannot automatically
transit back to the original mode when the following conditions exist:
• The peer STP device is shut down or removed.
• The port cannot detect the change.
