| boundary | Boundary clock instance. |
| ordinary | Ordinary clock instance. |
| seconds_log_base_2 | The log base 2 value of the seconds between successive announce messages. For example, to specify 8 seconds, use 3. The default value is 1, and the range is -2 to 4. |

The default value of the announce interval is log base 2 (1), or 2 seconds.
Use this command to configure the value of PTP announce interval time on the port(s) for sending announce messages. The announce interval is set using log base 2 values. The range is -2 to 4. This command is available only for boundary and ordinary clocks.
The following example configures announce interval to be 1/second on the clock port lpbk-gm of the ordinary clock:
# configure network-clock ptp ordinary announce interval 0 vlan lpbk-gm
The following example configures announce interval to be 2/second on the clock-port lpbk-gm of the boundary clock:
# configure network-clock ptp boundary announce interval -1 vlan lpbk-gm
This command was first available in ExtremeXOS 15.1.
