Usage guidelines
When you enable the spanning tree feature, the device operates in STP, RSTP, or MSTP mode, depending
on the spanning tree mode setting.
When the spanning tree feature is enabled, the device dynamically maintains the spanning tree status of
VLANs based on received configuration BPDUs. When the spanning tree feature is disabled, the device
stops maintaining the spanning tree status.

Usage guidelines
If a port on a device running MSTP or RSTP connects to an STP device, this port automatically transits to
the STP mode when the port receives STP BPDUs. However, if the peer STP device is shut down or
removed and the local device cannot detect the change, the local device cannot automatically transit
back to the original mode. In this case, you can perform an mCheck operation to forcibly transit the port
to operate in the original mode.
The device operates in STP, RSTP, or MSTP mode depending on the spanning tree mode setting.
