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
cost - The path cost for the port. (Range: 1-200,000,000)
(Range: 0 for auto-configuration, 1-65535 for short path cost method
