spanning-tree
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.
Syntax spanning-tree stp-id {cost cost | {loopguard | rootguard} | 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
then a number as the cost. The range is from 1 to 65535. The
defaults are:
• 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 .
loopguard Enter the keyword
loopguard
to enable STP loop guard on a port or port-channel
interface.
rootguard Enter the keyword rootguard to enable STP root guard on a port or port-channel
interface.
portfast [bpduguard
[shutdown-on-viol
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.
