Restarts the protocol migration process. Enables the BackboneFast feature. Prevents an interface from sending or receiving bridge protocol data units (BPDUs). Puts an interface in the error-disabled state when it receives a BPDU. Sets the path cost for spanning-tree calculations. Enables the extended system ID feature. Enables the root guard or the loop guard feature for all the VLANs associated with the selected interface. Overrides the default link-type setting for rapid spanning-tree transitions to the forwarding state. 2-400 Cisco Catalyst Blade Switch 3020 for HP Command Reference OL-8916-01
