Command Usage
The
spanning-tree system-bpdu-flooding
command has no effect if BPDU
flooding is disabled on a port (see the
spanning-tree port-bpdu-flooding
command, page 4-290).
Example
This command configures the path cost method used for Rapid Spanning Tree and
Multiple Spanning Tree. Use the
no
form to restore the default.
Syntax
spanning-tree pathcost method
{
long
|
short
}
no spanning-tree pathcost method
•
long
- Specifies 32-bit based values that range from 1-200,000,000.
This method is based on the IEEE 802.1w Rapid Spanning Tree Protocol.
•
short
- Specifies 16-bit based values that range from 1-65535.
This method is based on the IEEE 802.1 Spanning Tree Protocol.
Default Setting
Long method
Command Mode
Global Configuration
Command Usage
The path cost method is used to determine the best path between devices.
Therefore, lower values should be assigned to ports attached to faster media,
and higher values assigned to ports with slower media. Note that path cost
(page 4-285) takes precedence over port priority (page 4-286).
Example
This command configures the minimum interval between the transmission of
consecutive RSTP/MSTP BPDUs. Use the
no
form to restore the default.
Syntax
spanning-tree transmission-limit
count
no spanning-tree transmission-limit
count
- The transmission limit in seconds. (Range: 1-10)
