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.
S4810
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:
• 100 Mb/s Ethernet interface = 200000
• 1-Gigabit Ethernet interface = 20000
• 10-Gigabit Ethernet interface = 2000
• Port Channel interface with one 100 Mb/s Ethernet =
200000
• Port Channel interface with one 1 Gigabit Ethernet =
20000
• Port Channel interface with one 10 Gigabit Ethernet =
2000
• Port Channel with two 1 Gigabit Ethernet = 18000
• Port Channel with two 10 Gigabit Ethernet = 1800
• Port Channel with two 100 Mbps Ethernet = 180000
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.
shutdown-on-
violation (OPTIONAL) Enter the keywords
shutdown-on-violation
to hardware disable an interface when a BPDU is received
and the port is disabled.
priority priority Enter keyword
priority
then a value in increments of 16 as
the priority. The range is from 0 to 240. The default is 128 .
loopguard Enter the keyword
loopguard
to enable loop guard on an
RSTP port or port-channel interface.
rootguard Enter the keyword
rootguard
to enable root guard on an
RSTP port or port-channel interface.
Defaults Not configured.
