spanning-tree rstp
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.
S5000
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 followed by the port cost value. The range is
1 to 200000. The defaults are:
• 1-Gigabit Ethernet interface = 20000
• 10-Gigabit Ethernet interface = 2000
• 40-Gigabit Ethernet interface = 2000
• Port Channel interface with one 1-Gigabit Ethernet = 20000
• Port Channel interface with one 10-Gigabit Ethernet = 2000
• Port Channel interface with one 40-Gigabit Ethernet = 2000
• Port Channel with two 1-Gigabit Ethernet = 18000
• Port Channel with two 10-Gigabit Ethernet = 1800
• Port Channel with two 40-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.
