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.

Configuration restrictions and guidelines

•
You can disable the spanning tree feature for certain ports with the undo stp enable command
to exclude them from spanning tree calculation and save CPU resources of the device.
•
In PVST mode, when you globally enable the spanning tree feature the device automatically
enables the spanning tree feature for the first n (which is the number of PVST instances that the
switch supports and is 16 for the HPE 3100 v2 switch) of the existing VLANs by default. To
enable the spanning tree feature for other VLANs, you must first disable the spanning tree
feature for certain VLANs. This guideline does not apply if the number of existing VLANs on the
switch does not exceed n.
