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
Note
: The interpretation of this parameter has changed from v 1.2 to v 2.0. 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. The valid range is -7 to 5.
Delay Asymmetry
The transmission delay asymmetry for a link. See IEEE 1588 Section 7.4.2 Communication path
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. The valid range is -100000 to 100000.
Ingress latency
Ingress latency measured in ns, as defined in IEEE 1588 Section 7.3.4.2.
The valid range is -100000 to 100000.
Egress Latency
Egress latency measured in ns, as defined in IEEE 1588 Section 7.3.4.2.
The valid range is -100000 to 100000.
Version
The current implementation only supports PTP version 2.
