• clock class
• clock accuracy
• PTP variance (offsetScaledLogVariance)
• priority2
• clock identity
• steps removed from the grandmaster
The ordinary clock master, ordinary clock slave, and boundary clock set their local
parameters as follows:
If the profile setting for the clock is g8265dot1-2010, the precedence order for the best master
selection algorithm is:
• clock class
• priority
The ordinary clock master, ordinary clock slave, and boundary clock set their local
parameters as follows:
Table 33: Local Clock Parameters When Profile is set to ieee1588-2008
Parameter Value
clockIdentity Chassis MAC address following the guidelines of 7.5.2.2.2 of
IEEE 1588
clockClass 13 — local clock configured as ordinary clock master and is
locked to an external reference
14 — local clock configured as ordinary clock master and in
holdover after having been locked to an external source
248 — local clock configured as ordinary clock master and is in
free run or the router is configured as a boundary clock
255 — local clock configured as ordinary clock slave
clockAccuracy FE — unknown
offsetScaledLogVariance FFFF — not computed
