Table 3-3. PTP Master
Default Profile (Multicast) 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.
