bpduguard shutdown-onviolation err-disable vlan vlan-range cost number priority value loopguard rootguard 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. (OPTIONAL) Enter the keywords shutdown-on-violation to hardware disable an interface when a BPDU is received and the port is disabled. Enter the keywords err-disable to enable the port to be put into the error-disable state (EDS) if an error condition occurs. Enter the keyword vlan then the VLAN numbers. The range is from 1 to 4094. Enter the keyword cost then the port cost value. The range is from 1 to 200000. Defaults: • 100 Mb/s Ethernet interface = 200000. • 1-Gigabit Ethernet interface = 20000. • 10-Gigabit Ethernet interface = 2000. • Port Channel interface with one 100 Mb/s Ethernet = 200000. • Port Channel interface with one 1 Gigabit Ethernet = 20000. • Port Channel interface with one 10 Gigabit Ethernet = 2000. • Port Channel with two 1 Gigabit Ethernet = 18000. • Port Channel with two 10 Gigabit Ethernet = 1800. • Port Channel with two 100 Mbps Ethernet = 180000. Enter the keyword priority then the Port priority value in increments of 16. The range is from 0 to 240. The default is 128. (C-, S-, and E-Series only) Enter the keyword loopguard to enable loop guard on a PVST+ port or port-channel interface. (C-, S-, and E-Series only) Enter the keyword rootguard to enable root guard on a PVST+ port or port-channel interface. Defaults Not configured.
