IEEE8021ASClockClassValue
Denotes the traceability of the time or frequency of the local clock. The value shall be selected as follows: a) If the Default Parameter Data Set member gmCapable is TRUE, then clockClass is set to the value that reflects the combination of the LocalClock and ClockSource entities; else if the value that reflects the LocalClock and ClockSource entities is not specified or not known,clockClass is set to 248; b) If the Default Parameter Data Set member gmCapable is FALSE (see 8.6.2.1), clockClass is set to 255.
