ptp clock
Configures the PTP clock type on the switch and specifies the profile for the clock.
Syntax
ptp clock {boundary [hybrid] | end-to-end-transparent} [profile {g8275.1 |
system-default}]
Parameters
● boundary—Enables boundary clock.
● hybrid—Enables hybrid mode to use synchronous Ethernet for frequency synchronization.
● end-to-end-transparent—Enables end-to-end transparent clock.
● g8275.1—Configures the clock to adhere to the ITU G.8275.1 profile.
● system-default—Configures the clock to adhere to the system default profile.
Defaults System default profile, when PTP clock is configured.

Usage
Information
Enables the PTP clock and configures the clock type and profile on the switch. The clock identity is an
array of 8 bytes. The system determines the clock identity from the system MAC address. The most
significant 3 bytes (OUI portion) of the MAC address is assigned to the most significant 3 bytes of clock
identity. The least significant 3 bytes of the MAC address is assigned to the least significant 3 bytes of
the clock identity. Fourth and fifth bytes of clock identity can take on the one of the following values:
0xFF or 0xFE. The G8275.1 profile is applicable only for boundary clock. When you configure an attribute,
the new configuration overrides the attribute configuration that is defined in the profile.
Use the hybrid option to enable frequency synchronization using SyncE and synchronization of the time
of the day (ToD) and phase using PTP.
The no form of this command removes the configuration.
