4.2 PTP - CLOCK / GRANDMASTER (MENU 5.2)

This menu lets you set the following fields for the Grandmaster PTP port.
• Domain: 0 to 127; default = 0
• Priority 1: 0 to 255
• Priority 2: 0 to 255

4.3 PORT CONTROLS (MENU 5.3)

• Profile: Different profiles are supported by the DXD-8:
• Profile Port Timing Action:

4.4 PORT TIMING (MENU 5.4)

• Announce Interval: -3 to 4 (1/8sec - 16sec)
• Announce Receipt Timeout: 2 to 10 announce intervals
• Sync Interval: -7 to 1 (1/128sec - 2sec)
• Min Delay Req Interval: 1 to 32 the number of Sync Interval
Priorities are used in the BMCA to select the grandmaster - lower values have a higher priority (see 12.5 for more
information on the Grandmaster selection).

Among other things, IEEE1588 profiles define the range and default values of all configurable attributes. This is
very useful as selecting a specific profile on several networks would set all the parameters to the default values
and allow for a quick set up.
This menu gives you the option to set the timing values to the profile default values.
Sets the rate at which the master will send Announce messages.
Per IEEE 1588 this value should be uniform throughout a domain.
Sets the number of Announce messages that can be missed before it is assumed the master is no longer present and the
process of selecting a new one begins. Per IEEE 1588 this value should be uniform throughout a domain.
Sets the rate at which the master will send Sync messages
Sets the minimum time interval between 2 adjacent Delay Requests. This field shows a quantity of sync intervals:
"n sync intervals", where n = 1,2,4,8,16,32 (when n=1 it will say "1 sync interval").
This change does *not* apply to the peer-to-peer "MIN PDELAY REQ INTERVAL".
