Table 3-4. PTP Master
Telecom-2008 & ITU-G8265-1 Profiles (Unicast) Parameter Descriptions
Parameter
Description
two-step
Use to enable the grandmaster for two-step clock mode on
the specified port. If two-step clock mode is disabled, the
grandmaster uses one-step clock mode.
timescale
Use to select the timescale for the selected port. Use the
PTP timescale if the Grandmaster has a GNSS or PTP
connection for the clock. Use the ARB timescale if the
Grandmaster has an E1, T1, or SyncE signal for the clock.
Use the AUTO setting (recommended) to have the
Grandmaster automatically set the timescale based on the
selected clock source, GPS, T1/E1, PTP, or SyncE.
ptp-state
Use to enable or disable PTP functionality for the specified
port.
ttl
Use to set the IP header Time-to-Live value This field is
used to limit how many hops a packet will be transmitted in
a network.
priority-1
Sets the advertised Priority 1 value for the Grandmaster for
the specified port. PTP clients use the Best Master Clock
(BMC) algorithm to determine which Grandmaster
provides the best signal by first comparing Priority 1
values, then dynamic elements from the Grandmasters
(such as clock class, accuracy and variance), and then
Priority 2 values.
priority-2
Sets the advertised Priority 2 value for the Grandmaster for
the specified port. Clients use the Best Master Clock
(BMC) algorithm to determine which Grandmaster
provides the best signal by first comparing Priority 1
values, then dynamic elements from the Grandmasters
(such as clock class, accuracy and variance), and then
Priority 2 values.
domain
Sets the domain value for the Grandmaster clock.
IEEE-1588-2008 defines a domain as a logical grouping of
clocks that synchronize to each other using the protocol,
but that are not necessarily synchronized to clocks in
another domain.
