Dell EMC SmartFabric OS10 User Guide Release 10.5.0

This command applies only to STP-enabled ports. The command takes effect only when the BPDU guard is configured on a port.

When the detect cause option is enabled, the port is shut down whenever there is a BPDU guard violation.

When the option is disabled, the port is not shut down but moved to BLOCKING state whenever there is a BPDU guard violation. In this case, the port is operationally DOWN in spanning-tree mode and when the recovery timer expires after 300 seconds, the port is UP irrespective of the recovery cause configuration.

The no version of the command disables the detect cause option.
