portfast [bpduguard [shutdown-on-violation]] | priority
priority}
To disable Spanning Tree group on an interface, use the no spanning-tree
stp-id {cost cost | {loopguard | rootguard} | portfast
[bpduguard [shutdown-on-violation]] | priority priority}
command.
Parameters
stp-id Enter the STP instance ID. The range is 0.
cost cost Enter the keyword cost followed by a number as the cost.
The range is 1 to 65535. The defaults are:
• Gigabit Ethernet interface = 4.
• 10-Gigabit Ethernet interface = 2.
