2: Configuration level

According to the BMC algorithm in G.8275.1:

When two line clock sources are compared and other attributes the same, the interface with a lower local priority is preferentially selected.
When the local or external clock source competes with a line clock source and other attributes are the same, the two clock sources are compared against the local priority. The clock source with a lower local priority is preferentially selected.

# Set the local priority of a local G.8275.1 clock source to 120.
