Parameter Definition
Offset Scaled Log Variance (read only) One of the elements of the clock quality, as defined in IEEE-1588.
Priority 1 (read only) Always displays 128.
Priority 2 One of the factors used by the BMCA to determine the grandmaster.
The PTP 820
’s Boundary Clock node advertises this value when it is
not locked on an external grandmaster. The default value is 128
(user-configurable).
Domain Number The default value is 24 (user-configurable).
Slave Only (read only) Indicates whether the Boundary Clock node is operating in slave
mode only. In PTP 820, this is always set to
no .
Max Step Removed The maximum number of PTP clocks traversed from the grandmaster
to the slave clock in the local PTP 820 Boundary Clock node. If the
defined number is exceeded, packets from this grandmaster
candidate are discarded and the grandmaster will not be eligible for
use by the Boundary Clock node. The default value is 255 (user-
configurable).
Reset Port Counters In PTP 820, this is always set to no .
Clock Index In PTP 820, this is always set to 1 .
