3.12.12. spanning-tree bpdu-guard
Syntax
spanning-tree bpdu-guard
no spanning-tree bpdu-guard
Parameter
Default
BPDU guard is disabled
Mode
Interface Configuration
Usage
To enable the BPDU filter, use the command spanning-tree bpdu-guard in the Interface Configuration mode; and use no form of the command to disable the BPDU filter.
Example
The following example enables the BPDU guard for interface gi1.
Switch(config)# interface gi1
Switch(config-if)# spanning-tree bpdu-guard
