Syntax
spanning-tree priority priority
Parameter
priority
Specifies a bridge priority value for the switch. The range is 0 to
61,440, in increments of 4,096. Specify 0, 4096, 8192, 12288,
16384, 20480, 24576, 28672, 32768, 36864, 40960, 45056,
49152, 53248, 57344, or 61440. The default value is 32,768.
Mode
Global Configuration mode
Description
Use this command to assign the switch a bridge priority number. A lower
bridge priority value gives the switch a higher priority.The bridge priority is
used to influence which switch in the spanning tree domain becomes the
root bridge. The device that has the lowest bridge priority number
becomes the root bridge. If two or more devices have the same bridge
priority value, the device with the numerically lowest MAC address
becomes the root bridge.
To restore the default value, 32,768, use the NO SPANNING-TREE
PRIORITY command in the Global Configuration mode.
Confirmation Command
“SHOW SPANNING-TREE” on page 344
