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-on-
violation]] | priority priority} command.
Parameters
stp-id Enter the STP instance ID. The range is 0.
cost cost Enter the keyword cost then a number as the cost. The
range is from 1 to 65535. The defaults are:
• 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.
