If the profile setting for the clock is ieee1588-2008, the precedence order for the best master
selection algorithm is as follows:
• priority1
• clock class
• clock accuracy
• PTP variance (offsetScaledLogVariance)
• priority2
• clock identity
• steps removed from the grandmaster
The 7210 SAS sets its local parameters as follows:
If the profile setting for the clock is itu-telecom-freq (ITU G.8265.1 profile), the precedence order
for the best master selection algorithm is:
• clock class
• PTSF (Packet Timing Signal Fail) - Announce Loss (Miss 3 announce messages or do not
get Announce message for 6 seconds)priority
