Syntax
spanning-tree priority
priority
Parameters
priority Specifies a priority number for the switch.
Mode
Global Configuration mode
Description
Use this command to assign the switch a priority number. The device that
has the lowest priority number in the spanning tree domain becomes the
root bridge. If two or more devices have the same priority value, the device
with the numerically lowest MAC address becomes the root bridge.
The range is 0 to 61,440, in increments of 4,096. The range is divided into
the sixteen increments listed in Table 52. You specify the increment that
represents the desired bridge priority value. The default value is 32,768
(increment 8).
