Range: 0 (OPTIONAL) Enter the keyword cost followed by a number as the cost. Range: 1 to 65535 Defaults: 100 Mb/s Ethernet interface = 19 1-Gigabit Ethernet interface = 4 10-Gigabit Ethernet interface = 2 Port Channel interface with 100 Mb/s Ethernet = 18 Port Channel interface with 1-Gigabit Ethernet = 3 Port Channel interface with 10-Gigabit Ethernet = 1 (OPTIONAL) Enter keyword priority followed by a number as the priority. Range: zero (0) to 15. Default: 8 (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. Defaults cost = depends on the interface type; priority = 8 Command Modes INTERFACE Command History Version 8.3.3.1 Version 8.2.1.0 Version 7.7.1.0 Version 7.5.1.0 Version 6.2.1.1 Introduced on S60 Introduced hardware shutdown-on-violation option Introduced on S-Series Introduced on C-Series Introduced Usage Information If you enable portfast bpduguard on an interface and the interface receives a BPDU, the software disables the interface and sends a message stating that fact. The port is in ERR_DISABLE mode, yet appears in the show interface commands as enabled. If shutdown-on-violation is not enabled, BPDUs will still be sent to the RPM CPU. 1026 | Spanning Tree Protocol (STP)
