Table 3-39
Table 3-39. Spanning Tree Switch Settings Parameters
Parameter Description
Indicates the management-assigned priority value of the bridge ID in hexadecimal
Bridge Priority
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
Range
Designated Indicates the bridge ID of the root bridge, as determined by the STA.
Root
Default
Range
Root Port Indicates the specific unit in a stack or standalone switch's port number that offers the
lowest path cost to the root bridge.
Default
Range
Root Path Cost Indicates the path cost from this switch port to the root bridge.
Default
Range
Hello Time Indicates the Actual Hello Interval, the amount of time between transmissions of
configuration Bridge Protocol Data Units (BPDUs) 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
Range
Maximum Age Indicates the Maximum Age Time parameter value that the root bridge is currently using.
Time 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.
