• 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.
• Version
PTP version used by this port
• Mcast Addr
Configured destinaton address for multicast packets (PTP default or LinkLocal)
• Not Slave
TRUE indicates that this interface cannot enter slave mode
• Local Prio
1-255, priority used in the 8275.1 BMCA
• 2 Step Flag
Option to override the 2-step option on port level */ // IEEE 802.1AS specific
parameters are only available when the 802.1AS profile is selected
