Enable STP on the port
no spanning-tree
Disable STP on the port

Parameter
Description
Parameter
<instance>
STP bridge instance. Must be 0 (zero)
cost
{ <cost> | auto }
Controls the path cost incurred by the port. Auto setting will set the
cost as appropriate by link speed using 802.1D recommended values.
User defined value can also be entered and the valid range is 1-
200000000. Default is auto.
port-priority
<prio>
Represents the port priority. Must be divisible by 16, supported
values are 0-240. For example, 16, 32, etc. Default value is 128
l
ink-type
{ point-to-point
| shared | auto }
Controls whether the port connects to a point-to-point LAN rather
than to a shared medium. Default is auto.
edge
Defines whether the port is connecting directly to edge devices.
Default is non-edge.
auto-edge
Enables auto edge detection on the port.
restricted-role
If enabled causes the port not to be selected as Root port.
restricted-tcn
If enabled causes the port not to propagate received topology
change notifications to other ports.
Bpdu-guard
If enabled causes the port to disable itself upon receiving valid
BPDUs.
Default
N.A
Mode
Port List Interface Mode
Usage
Configure STP CIST settings for the specific physical and aggregated ports. Use the no version of
the command to revert to default.
