Here are the guidelines to this feature:

BPDU guard is configured for each port and has only two possible
settings: enabled or disabled. The default setting is disabled.

This feature is supported on the base ports of the switch and any
fiber optic transceivers installed in the unit.

Note

A port disabled by the BPDU guard feature remains in that state until
you enable it with the management software. If a port is still
receiving BPDUs, you should disconnect the network cable before
enabling it to prevent the feature from disabling the port again.
