in selecting the best master clock. The priority1-value is advertised in the master clock's
announce message to clock clients. The default value is 128.

(Optional) Configure the tie-breaker in selecting the best master clock (0 through

(Optional) Enable unicast negotiation. Unicast negotiation is a method by which the

announce, synchronization, and delay response packet rates are negotiated between
the master clock and the clock client before a PTP session is established.

NOTE: Unicast negotiation, when enabled, does not allow you to commit
packet rate–related configurations.

A Precision Time Protocol (PTP) master boundary clock sends PTP messages to the
clients (ordinary and boundary) so that they can establish their relative time offset from
this master's clock or clock reference. You cannot configure an ordinary master clock on
a device. The master boundary clock synchronizes time through a boundary slave port.
To configure a master boundary clock, you must include the
is the same for different master clocks in a network.
