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.
Syntax
spanning-tree rstp {cost
port-cost
| edge-port [bpduguard
[shutdown-on-violation]] | bpdufilter | priority
priority
|
{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
• 40-Gigabit Ethernet interface =
1400
• Port Channel interface with one 10 Gigabit Ethernet =
2000
• Port Channel interface with one 40 Gigabit Ethernet =
1400
• Port Channel with two 10 Gigabit Ethernet =
1800
• Port Channel with two 40 Gigabit Ethernet =
600
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.
bpdufilter
(OPTIONAL) Enter the keyword
bpdufilter
to enable
BPDU Filter to stop sending and receiving BPDUs on port
enabled interfaces.
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
.
rootguard
Enter the keyword
rootguard
to enable root guard on an
RSTP port or port-channel interface.
Defaults
Not configured.
