on
for
data ports. STG port parameters include:

Port priority

Port path cost

Spanning Tree Port Options
Command Syntax and Usage
[no] spanning ­ tree stp
<1 ‐ 128>
enable
Enables or disables STG on the port.
Command mode: Interface port/Interface portchannel
spanning ­ tree stp
<1 ‐ 128>
path ­ cost
<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
spanning ­ tree 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 spanning ­ tree stp
<1 ‐ 128>
Resets the STG configuration to its default settings.
Command mode: Interface port/Interface portchannel
show interface port
<port alias or number>
spanning ­ tree stp
<1 ‐ 128>
Displays the current STG port parameters.
Command mode: All
