Dell C1048P Port Extender Networking Command-Line Reference Guide for the C900 - Page 1985

spanning-tree 0 Assigns a Layer 2 interface to STP instance 0 and configures a port cost or port priority, or enables loop guard, root guard, or the Portfast feature on the interface. C9000 Series Syntax spanning-tree stp-id {cost cost | | portfast [bpduguard [shutdown-on-violation]] | priority priority} To disable Spanning Tree group on an interface, use the no spanning-tree stp-id {cost cost | portfast [bpduguard [shutdown-onviolation]] | priority priority} command. Parameters stp-id cost cost Enter the STP instance ID. The range is 0. Enter the keyword cost then a number as the cost. The range is from 1 to 65535. The defaults are: • 10-Gigabit Ethernet interface = 2. • Port Channel interface with 10-Gigabit Ethernet = 1. portfast [bpduguard [shutdown-onviol ation]] Enter the keyword portfast to enable Portfast to move the interface into Forwarding mode immediately after the root fails. Enter the optional keyword bpduguard to disable the port when it receives a BPDU. Enter the optional keyword shutdown-on-violation to hardware disable an interface when a BPDU is received and the port is disabled. priority priority Enter keyword priority then a number as the priority. The range is from zero (0) to 15. The default is 8. Defaults cost = depends on the interface type; priority = 8 Command Modes INTERFACE Command History This guide is platform-specific.
