3HE 11010 AAAC TQZZA Edition: 01
Description This command configures the interval between transmission of synchronization packets for a
PTP port in a master state. For PTP with IP encapsulation (clock-id is 1 to 16), this value is
also used as the interval for Delay-Req messages for this clock.
The no form of this command returns the configuration to the default value. The default value
varies depending on the configuration of the profile command.
Default –6 when the profile is configured as ieee1588-2008
–6 when the profile is configured as itu-telecom-freq for a clock-id of 1 to 16; this profile does
not apply when the clock-id is csm
–4 when the profile is configured as g8275dot1-2014
Parameters log-sync-interval — specifies the expected interval between the reception of
synchronization messages
Values –7 to –4, where –7 is 128 packets/s, –6 is 64 packets/s, –5 is
32 packets/s, and –4 is 16 packets/s, when the clock-id is 1 to 16 (all
profiles)
–6 to 0, where –6 is 64 packets/s, –5 is 32 packets/s, –4 is
16 packets/s, –3 is 8 packets/s, –2 is 4 packets/s, –1 is 2 packets/s,
and 0 is 1 packet/s, when the clock-id is csm and the profile is
configured as ieee1588-2008 or g8275dot1-2014 (profile itu-
telecom-freq does not apply when the clock-id is csm)
master-only
Syntax master-only {true | false}
Context config>system>ptp>clock>port
Description This command prevents the local port from ever entering the slave state. This ensures that
the 7705 SAR never draws synchronization from an attached external device.
This command only applies when the profile command is set to g8275dot1-2014.
If the clock-type command is set to ordinary slave, the master-only value is set to false and
cannot be changed. Similarly, if the clock-type command is set to ordinary master, the
master-only value is set to true and cannot be changed.
Default true (when the PTP clock-type is set to boundary)
priority1
Syntax priority1 priority-value
