The Telecom Profiles (ITU-T G.8275.1 and G.8275.2) specify an
|
||||
alternate Best Master Clock Algorithm (BMCA) with a unique data set
|
||||
comparison algorithm. The value of this option is associated with the
|
||||
local clock and is used as a tie breaker whenever clockClass,
|
||||
clockAccuracy, offsetScaledLogVariance, and priority2 are equal. This
|
||||
option is only used when "dataset_comparison" is set to "telecom".
|
||||
The default value is 128.
|
||||
|
||||
Warning: the BMCA is guaranteed to produce a spanning tree (that is, a
|
||||
timing network without loops) only when using the default values of
|
||||
G.8275.defaultDS.localPriority and G.8275.portDS.localPriority.
|

Careful network engineering is needed when using non-default values.
