Spanning Tree Commands
4-171
4
spanning-tree spanning-disabled
This command disables the spanning tree algorithm for the specified interface. Use
the no form to reenable 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.
spanning-tree cost
This command configures the spanning tree path cost for the specified interface.
Use the no form to restore the default.
Syntax
spanning-tree cost cost
no spanning-tree cost
cost - The path cost for the port. (Range: 1-200,000,000))
The recommended range is:
• Ethernet: 200,000-20,000,000
• Fast Ethernet: 20,000-2,000,000
• Gigabit Ethernet: 2,000-200,000
Default Setting
• Ethernet – half duplex: 2,000,000; full duplex: 1,000,000; trunk: 500,000
• Fast Ethernet – half duplex: 200,000; full duplex: 100,000; trunk: 50,000
• Gigabit Ethernet – full duplex: 10,000; trunk: 5,000
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• This command is used by the Spanning Tree Algorithm 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.
