Description
•
Port
Static member port Identity : Port number [1..max port no]
•
Stat
Dynamic member portState: Current state of the port.
•
MDR
Dynamic member log Min Delay Req Interval: The delay request interval
announced by the master.
•
Peer Mean Path Del
The path delay measured by the port in P2P mode. In E2E mode this value is 0
•
Anv
The interval for issuing announce messages in master state. Range is -3 to 4.
•
ATo
The timeout for receiving announce messages on the port. Range is 1 to 10.
•
Syv
The interval for issuing sync messages in master. Range is -7 to 4.
•
Dlm
Configurable member delayMechanism:
The delay mechanism used for the port:
e2e End to end delay measurement
p2p Peer to peer delay measurement.
Can be defined per port in an Ordinary/Boundary clock.
In a transparent clock all ports use the same delay mechanism, determined by
the clock type.
•
MPR
The interval for issuing Delay_Req messages for the port in
E2e
mode.
This value is announced from the master to the slave in an announce message.
The value is reflected in the MDR field in the Slave
The interval for issuing Pdelay_Req messages for the port in P2P mode
Range is -7 to 5.
Note:
The interpretation of this parameter has changed from release 2.40. In earlier
versions the value was interpreted relative to the Sync interval, this was a
violation of the standard, so now the value is interpreted as an interval. I.e.
MPR=0 => 1 Delay_Req pr sec, independent of the Sync rate.
•
Delay Asymmetry
If the transmission delay for a link in not symmetric, the asymmetry can be
configured here, see IEEE 1588 Section 7.4.2 Communication path asymmetry
Range is -100000 to 100000.
Version
The current implementation only supports PTP version 2
•
Ingress latency
Ingress latency measured in ns, as defined in IEEE 1588 Section 7.3.4.2.
Range is -100000 to 100000.
•
Egress Latency
Egress latency measured in ns, as defined in IEEE 1588 Section 7.3.4.2.
Range is -100000 to 100000.
