Basic System Configuration Guide System Management
Edition: 01 3HE 11010 AAAC TQZZA 389
Parameters domain-value — specifies the PTP device domain value
Values 0 to 127 when the profile is configured as either ieee1588-2008 or
itu-telecom-freq
24 to 43 when the profile is configured as g8275dot1-2014
dynamic-peers
Syntax [no] dynamic-peers
Context config>system>ptp>clock
Description This command allows a slave clock to connect to the master clock without the master being
aware of it. Once connected, the master clock or boundary clock assigns the slave a PTP port
and/or peer ID dynamically.
This command is only available when the clock-id parameter value is 1 to 16.
Dynamic peers are not stored in the configuration file. If a master clock with dynamic peers
goes down and comes back up, the slave clocks renegotiate to it and are reassigned
resources on the master clock or boundary clock.
The no form of this command disables dynamic peers. In this case, the user must manually
program any slave peer clocks into the master clock or boundary clock in order for those
clocks to accept those slaves.
Default no dynamic-peers
freq-source
Syntax freq-source {ptp | ssu}
no freq-source
Context config>system>ptp>clock
Description This command specifies the administrative frequency source to use for a given PTP clock.
This selection influences the operational frequency source selected by the system for the
given PTP clock. If PTP is only used for time of day and the node SSU is being synchronized
through a better frequency source externally (for example, through the external timing input
port) or through line timing (for example, through a synchronous Ethernet or T1/E1 port), SSU
may be configured as the frequency source for the PTP clock. This option allows PTP to use
the SSU frequency where available.
This command is only available when the clock-id parameter value is 1 to 16.
The no form of the command returns the configuration to the default setting.
