By default, Spanning Tree is turned off for management ports, and turned on for
data ports. STG port parameters include:
Port priority
Port path cost
Table 228.

Command Syntax and Usage
[no] spanningtree stp <1‐128> enable
Enables or disables STG on the port.
Command mode: Interface port/Interface portchannel
spanningtree stp <1‐128> pathcost <1‐200000000, 0 for default)>
Configures the port path cost. The port path cost is used to help determine the
designated port for a segment. Port path cost is based on the port speed, and is
calculated as follows:
1Gbps = 20000
10Gbps = 2000
The default value of 0 (zero) indicates that the default path cost will be
computed for an auto negotiated link speed.
Command mode: Interface port/Interface portchannel
spanningtree stp <1‐128> priority <0‐240>
Configures the port priority. The port priority helps determine which bridge
port becomes the designated port. In a network topology that has multiple
bridge ports connected to a single segment, the port with the lowest port
priority becomes the designated port for the segment.
The default value is 128.
RSTP/PVRST: The range is 0 to 240, in steps of 16 (0, 16, 32...).
Command mode: Interface port/Interface portchannel
default spanningtree stp <1‐128>
Resets the STG configuration to its default settings.
Command mode: Interface port/Interface portchannel
show interface port <port alias or number> spanningtree stp <1‐128>
Displays the current STG port parameters.
Command mode: All
