STP can be configured on ONEPolicy-enabled ports to prevent loop at the edge. In this configuration, it isrecommended to modify the port blocking mechanism to spanning-tree-group by running the command configure forwarding L2-protocol blocking-type spanning-tree-group. To revert to the default blocking mechanism, use the command configure forwarding L2-protocol blocking-type ingress-filtering.
The blocking type configuration can be verified with the command show forwarding configuration.
