Disabled : Two-Step Mode is enabled
Enabled : One-Step Mode is enabled
[Default=Disabled]
Note: One-Step Mode is not supported with the Peer-to-Peer Delay
Mechanism.
The current implementation of one- step mode involves a software oriented
timestamping. The two-step mode imlements a hardware oriented timestamping,
insensitive to software execution time variations. The Two- step mode is recom
mended, as it increases the PTP Clock's accuracy
Delay Mechanism : Will be one of the following:
E2E : End-to-End Delay Mechanism
P2P : Peer-to-Peer Mechanism
Disabled : No Delay Mechanism
Default setting:
E2E
Note: Peer-to-Peer Delay Mechanism is only applicable on
networks equipped with Transparent Clocks (switches/routers
IEEE 1588 compatible). Peer-to-Peer Delay Mechanism is not
supported in Unicast transmission mode.
PPS Offset : See "Advanced tab settings" on page 369.
