Table 3-26 describes the Spanning Tree Switch Settings parameters.

Table 3-26. Spanning Tree Switch Settings Parameters

Parameter Description

Bridge Priority 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,

follow ed by the hard ware addresses .

Default Value 8000

Range 0 to 65535

Designated

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

Default Value 8000 (bridge_id)

Range 0 to 65535

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

Default Value 0

Range 0 to 16

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

Default Value 0

Range Not applicable

Hello Time Indicates the Actual Hello Interval, the amount of time between transmissions of

configuration Bridge Protocol Data Uni ts (BP DUs) t hat the root bridge is cur rently using.

Note t hat all bridges participat ing in the spanning tree netw ork use the root bridge’s Hello

Interval parameter value. See also Bridge Hello Time.

Default Value 2 seconds

Range 1 to 10 seconds

Maximum Age

Time I ndica tes the Max imu m Age Tim e par amete r v alue that the roo t bridge is currentl y usin g.

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

Maximu m Age Time parameter value for all bri dges participatin g in th e spanning tree

network. See also Bridge Maximum Age Time.

Default Value 20 seconds

Range 6 to 40 seconds
