enable the feature on all associated ports before you enable it globally.

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.
