This command configures the path cost on a spanning instance in the
Multiple Spanning Tree. Use the no form to restore the default auto-
configuration mode.

instance-id - Instance identifier of the spanning tree.
(Range: 0-4094)
cost - Path cost for an interface. (Range: 0 for auto-configuration,
1-65535 for short path cost method
cost method)
The recommended path cost range is listed in
page 1053.
D S
EFAULT ETTING
By default, the system automatically detects the speed and duplex mode
used on each port, and configures the path cost according to the values
shown in Table 128. Path cost "0" is used to indicate auto-configuration
mode. When the short path cost method is selected and the default path
cost recommended by the IEEE 8021w standard exceeds 65,535, the
default is set to 65,535.
