Note:
Select Two Step operation if the Operating Mode is unknown.
4.
Delay Mechanism
By default the 'DELAY MECHANISM' will be set to P2P, which will set the delay mechanism to peer to peer as
defined in IEEE 1588v2-2008.
5.
Priority #1 and Priority #2
By default, both Priority #1 and Priority #2 are set to 128 and cannot be changed.
6.
Configure Default Domain
Modify the 'DEFAULT DOMAIN' number if required, otherwise it is recommended that it is left as its default
value of '0'.
A domain consists of one or more PTP devices communicating with each other. By default, PTP aware
devices are configured with a domain of '0'. Changing the domain will cause only devices with the specified
domain to communicate using the PTP protocol. The input range is 0 to 127.
7.
Peer Delay Request Interval
By default, the 'PEER DELAY REQUEST INTERVAL' is set to 1 second
8.
Announce Interval
By default, the 'ANNOUNCE INTERVAL' is set to 1 second
9.
Announce Receipt Timeout
By default the 'ANNOUNCE RECEIPT TIMEOUT' is set to 3. This means that after 3 announce intervals, if
the device has not recieved an announce message it will trigger an announce receipt timeout event, which will
move the port into a listening state.
10.
Sync Interval
By default, the 'SYNC INTERVAL' is set to 1 second
11.
BMCA
By default, the 'BMCA' operations will be set to 'BASIC' and will operate as defined in IEEE 1588v2-2008
12.
Clock Class Rules
By default, the 'CLOCK CLASS RULES' operations will be set to 'BASIC' and will operate as defined in IEEE
1588v2-2008
13.
Configure TLV Settings
With the C37.238-2011 profile the ATOI TLV is always included in outgoing messages, and is required on
incoming messages — otherwise they will be ignored. The same applies for the C37.238 TLV, however, the
C37.238 TLV includes two configurable settings — the C37.238 Grandmaster ID, and the C37.238 Network
Time Inaccuracy.
