System Command Reference
local-priority
Syntax local-priority local-priority
Context configure>system>ptp
configure>system>ptp>peer
configure>system>ptp>port
Description This command configures the local priority used to choose between PTP masters in the best master
clock algorithm (BMCA). This setting is relevant when the profile is set to either g8265dot1-2010 or
g8275dot1-2014. The parameter is ignored when any other profile is selected.
The value 1 is the highest priority and 255 is the lowest priority. The priority of a peer cannot be
configured if the PTP profile is ieee1588-2008.
For g8265dot1-2010, this parameter configures the priority used to choose between master clocks with
the same quality (see G.8265.1 for more details).
For g8275dot1-2014, this parameter sets the value of the localPriority associated with the Announce
messages received from the external clocks (ptp>peer or ptp>port), or the local clock (PTP). See
G.8275.1 for detailed information.

Parameters
local-priority — Specifies the value of the local priority.
master-only
Syntax master-only {true | false}
Context configure>system>ptp>port
Description This command is used to restrict the local port to never enter the slave state. Use the command to
ensure that the 7750 SR never draws synchronization from the attached external device.
This parameter is only effective when the profile is set to g8275dot1-2014.
Note: The ITU-T G.8275.1 (07/2014) recommendation used the term 'notSlave' for this functionality;
however, the IEEE has added this capability into the next edition of the 1588 standard using the term
masterOnly. These are equivalent.
Default true
