Syntax Parameters Defaults Command Modes Command History spanning-tree rstp {cost port-cost | edge-port [bpduguard [shutdown-on-violation]] | priority priority | {loopguard | rootguard}} cost port-cost edge-port bpduguard shutdown-on-vi olation 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 (C-, S-, and E-Series TeraScale only) Enter the keyword loopguard to enable loop guard on an RSTP port or port-channel interface. (C-, S-, and E-Series TeraScale only) Enter the keyword rootguard to enable root guard on an RSTP port or port-channel interface. Not configured INTERFACE Version 8.3.19.0 Version 8.4.2.1 version 8.3.7.0 Version 8.2.1.0 Introduced on S4820T Introduced the loopguard and rootguard options on the E-Series TeraScale, C-Series, and S-Series.
