spanning-tree rstp Configure an RSTP interface with one of these settings: port cost, edge port with optional bridge port data unit (BPDU) guard, port priority, loop guard, or root guard. C9000 Series Syntax Parameters spanning-tree rstp {cost port-cost | edge-port [bpduguard [shutdown-onviolation]] | priority priority | {loopguard | rootguard}} cost port-cost Enter the keyword cost then the port cost value. The range is from 1 to 200000. The defaults are: • 10-Gigabit Ethernet interface = 2000 • Port Channel interface with one 10-Gigabit Ethernet = 2000 • Port Channel with two 10 Gigabit Ethernet = 1800 edge-port bpduguard Enter the keywords edge-port to configure the interface as a rapid spanning tree edge port. (OPTIONAL) 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. shutdown-onviolation priority priority loopguard rootguard (OPTIONAL) Enter the keywords shutdown-on-violation to hardware disable an interface when a BPDU is received and the port is disabled. Enter keyword priority then a value in increments of 16 as the priority. The range is from 0 to 240. The default is 128. Enter the keyword loopguard to enable loop guard on an RSTP port or portchannel interface. Enter the keyword rootguard to enable root guard on an RSTP port or portchannel interface.
