Spanning Tree Commands (Cont.)
Command Function
spanning-tree priority
This command configures the
spanning tree priority globally for
this switch.
Use the no form to restore the
default.
Syntax:
spanning-tree priority priority
no spanning-tree priority
• priority - Priority of the bridge.
Range – 0-61440, in steps of 4096;
Options: 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768,
36864, 40960, 45056, 49152, 53248, 57344, 61440
Default Setting: 32768
Command Mode: Global Configuration
Command Usage: Bridge priority is used in selecting the root device, root
port, and designated port. The device with the highest priority becomes the
STA root device. However, if all devices have the same priority, the device
with the lowest MAC address will then become the root device.
Example:
Console(config)#spanning-tree priority 40960
Console(config)#
spanning-tree pathcost
method
This command configures the
path cost method used for Rapid
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 0-200,000,000.
• short - Specifies 16-bit based values that range from 0-65535.
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 (see spanning-tree cost on page 251) takes pre-
cedence over port priority (see spanning-tree port-priority on page 251).
Example:
Console(config)#spanning-tree pathcost method long
Console(config)#
spanning-tree transmission-
limit
This command configures the
minimum interval between the
transmission of consecutive
RSTP 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)
Default Setting: 3
Command Mode: Global Configuration
Command Usage: This command limits the maximum transmission rate for
BPDUs.
Example:
Console(config)#spanning-tree transmission-limit 4
Console(config)#
spanning-tree spanning-
disabled
This command disables the
Spanning Tree Algorithm for the
specified interface.
Use the no form to re-enable the
Spanning Tree Algorithm for the
specified interface.
Syntax:
[no] spanning-tree spanning-disabled
Default Setting: Enabled
Command Mode: Interface Configuration (Ethernet, Port Channel)
Example: This example disables the Spanning Tree Algorithm for port 5:
Console(config)#interface ethernet 1/5
Console(config-if)#spanning-tree spanning-disabled
Console(config-if)#
