Enabling the spanning tree feature

You must enable the spanning tree feature for the device before any other spanning tree related
configurations can take effect. In STP, RSTP, or MSTP mode, make sure the spanning tree feature is
enabled globally and on the desired ports. In PVST mode, make sure the spanning tree feature is
enabled globally, in the desired VLANs, and on the desired ports.
To exclude specific ports from spanning tree calculation and save CPU resources, disable the
spanning tree feature for these ports with the undo stp enable command. Make sure no loops occur
in the network after you disable the spanning tree feature on these ports.
