Syntax Parameters spanning-tree pvst {edge-port [bpduguard [shutdown-on-violation]] | err-disable | vlan vlan-range {cost number | priority value} | loopguard | rootguard} edge-port bpduguard Enter the keyword edge-port to configure the interface as a PVST+ edge port. Enter the keyword portfast to enable Portfast to move the interface into forwarding mode immediately after the root fails. Enter the keyword bpduguard to disable the port when it receives a BPDU.
