Function
Enable the BPDU guard with the port in which the portfast function is valid.
If the port having the enabled BPDU guard receives a BPDU, this port is shut down and its communication fails. During this
time, the received BPDU is not processed.
If the port is shut down, you can enable the communication either using the "no shutdown" command or by enabling the
"spanning-tree portdast errdisable-timeout" command and automatically starting the communication at the time set by the
timer.
The no form to is used to return to the default setup.
