spanning-tree link-type p2p
{auto|force-true|force-false}
no spanning-tree link-type
Set the port link type.
spanning-tree portfast [bpdufilter| bpduguard]
no spanning-tree portfast
Set and cancel the port to be an
boundary port. bpdufilter receives the
BPDU discarding; bpduguard receives
the BPDU will disable port; no parameter
receives the BPDU, the port becomes a
non-boundary port.
