Spanning Tree Commands
4-211
4
specify the maximum number of bridges that will propagate a BPDU. Each
bridge decrements the hop count by one before passing on the BPDU. When
the hop count reaches zero, the message is dropped.
Example
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
(Range: 0 for auto-configuration, 1-65535 for short path cost method
23
,
1-200,000,000 for long path cost method)

23. Use the spanning-tree pathcost method command on page 4-206 to set the path cost
method.
