Table 3-14 describes the Spanning Tree Switch Settings parameters.

Indicates the management-assigned priority value of the bridge ID in hexadecimal 
notation, which is the most significant byte of the bridge ID. The STA uses this parameter 
to determine the root bridge (or designated bridge). For example, the bridge with the 
lowest bridge ID becomes the root bridge, with Bridge Priority values compared first, 
followed by the hardware addresses.

Default Value

8000

Range

0 to 65535

Indicates the bridge ID of the root bridge, as determined by the STA.

Default Value

8000 (bridge_id)

Range

0 to 65535

Indicates the switch port number that offers the lowest path cost to the root bridge.

Default Value

0

Range

0 to 16

Indicates the path cost from this switch port to the root bridge.

Default Value

0

Range

Not applicable

Indicates the Actual Hello interval (the amount of time between transmissions of 
Configuration Bridge PDUs) that the root bridge is currently using.

Note that all bridges participating in the spanning tree network use the root bridge’s Hello 
Interval parameter value. See also Bridge Hello Time.

Default Value

2 seconds

Range

1 to 10 seconds

Indicates the Maximum Age Time parameter value that the root bridge is currently using. 
This value specifies the maximum age that a Hello message can attain before it is 
discarded.

Note that the root bridge’s Maximum Age Time parameter value becomes the (actual) 
Maximum Age Time parameter value for all bridges participating in the spanning tree 
network. See also Bridge Maximum Age Time.

Default Value

20

Range

6 to 40 seconds
