spanning-tree rstp c e s 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. Syntax spanning-tree rstp {cost port-cost | edge-port [bpduguard [shutdown-on-violation]] | priority priority | {loopguard | rootguard}} Parameters cost port-cost edge-port bpduguard shutdown-onviolation priority priority loopguard rootguard Enter the keyword cost followed by the port cost value. Range: 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 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. (OPTIONAL) Enter the keyword shutdown-on-violation to hardware disable an interface when a BPDU is received and the port is disabled. Enter keyword priority followed by a value in increments of 16 as the priority. Range: 0 to 240. Default: 128 Enter the keyword loopguard to enable loop guard on an RSTP port or port-channel interface. Enter the keyword rootguard to enable root guard on an RSTP port or port-channel interface.
