Enter the keywords edge-port to configure the interface as a rapid
spanning tree edge port.
(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.
(OPTIONAL) Enter the keywords shutdown-on-violation to
hardware disable an interface when a BPDU is received and the port
is disabled.
priority
Enter keyword priority followed by a value in increments of 16 as
the priority. The range is 0 to 240. The default is 128.
(C-, S-, and E-Series TeraScale only) Enter the keyword loopguard
to enable loop guard on an RSTP port or port-channel interface.
(C-, S-, and E-Series TeraScale only) Enter the keyword rootguard
to enable root guard on an RSTP port or port-channel interface.
