User Description
Optional user description of the PTP application
-
PTP Version
Per port
- PTP version is seleced per port. The focus is
shifted to the PTP Per port settings
Version 1
– equals IEEE1588-2002.
Not all these settings are relevant for IEEE1588-2002. By
choosing PTP version 1, the menu changes to reflect the
relevant settings for IEEE1588-2002.
Version 2
– equals IEEE1588-2008
-
Network Protocol
Per Port
– Packet encapsulation is selectable per port
UDP/Ipv4
– PTP Packets are transported over UDP/Ipv4
IEEE802.3/Ethernet
– PTP packets are transported over
Layer2 IEEE803.3
-
Datagram
Per Port
– Packet datagram is selectable per port
Multicast
– One to many communication. The PTP stack will
send IGMP join to the relevant MC groups for PTP.
Unicast
– One to one communication
-
Pdelay req interval
The frequency of Path Delay request messages
-
Announce interval
The frequency of Announce messages
-
Sync interval
The frequency of Sync messages
-
Delay request
interval
In SLAVE state, this is the number of Delay request
messages sent per second.
Note that a MASTER clock may override this setting and
send fewer Delay responses.
In MASTER state, this value has no meaning.
-
Max incoming
delay req/s
In MASTER state, this number denotes the maximum
number of delay requests per second which is processed per
slave. In other words, the maximum number of delay
responses which is sent to each slave per second. The
number is linked to the Sync interval and will be updated
when the Sync interval is updated.
In SLAVE state this number has no meaning.
-
Operation mode
One Step
– Time stamps are inserted on the fly in event
packets (Sync, Delay_req). Transparent clock operation is
also 1-step.
Two Step
– Event packets are time stamped and time
information is updated in general packets (Follow_up,
Delay_resp, Pdelay_Resp_FU ). Transparent clock operation
is also 2-step.
