Configure an RSTP interface with one of these settings: port cost, edge port with optional bridge port data
unit (BPDU) guard, port priority, loop guard, or root guard.
C9000 Series
Syntax
spanning-tree rstp {cost port-cost | edge-port [bpduguard
[shutdown-on-violation]] | priority priority | {loopguard |
rootguard}}
Parameters
cost port-cost Enter the keyword
cost
then the port cost value. The range is
from 1 to 200000. The defaults are:
• 10-Gigabit Ethernet interface = 2000
• Port Channel interface with one 10-Gigabit Ethernet =
2000
• Port Channel with two 10 Gigabit Ethernet = 1800
edge-port Enter the keywords
edge-port
to configure the interface as a
rapid spanning tree edge port.
bpduguard
(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.
