errdisable detect cause bpduguard
Congures the port to be shut down or moves the port to blocked state on detecting a BPDU guard violation.

errdisable detect cause bpduguard
Parameters None
Default Enabled
Command Mode CONFIGURATION
Usage Information
This command applies only to STP-enabled ports. The command takes eect only when BPDU guard is congured
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, the port is UP irrespective of the recovery cause conguration.
The no version of the command disables the detect cause option.
Example
OS10(config)# errdisable detect cause bpduguard
