=== PTP basic (IEEE 802.1AS)
|
|
|
|
ifdef::topdoc[:imagesdir: {topdoc}../../test/case/ptp/basic]
|
|
|
|
==== Description
|
|
|
|
Verify basic PTP operation end-to-end: clock configuration, port state
|
|
transitions, and clock servo convergence.
|
|
|
|
Two Ordinary Clocks are connected back-to-back. The grandmaster is
|
|
configured with `priority1=1` so it always wins the BTCA election; the
|
|
time receiver is configured with `time-receiver-only` so it never
|
|
attempts to become grandmaster. The test is run once per supported
|
|
profile, covering both IEEE 1588-2019 (UDP/IPv4, E2E) and IEEE 802.1AS
|
|
(Layer 2, P2P).

|
|
|
|
==== Sequence
|
|
|
|
. Set up topology and attach to DUTs
|
|
. Configure grandmaster (OC, ieee802-dot1as, priority1=1) and time receiver (ieee802-dot1as, priority1=128, client-only)
|
|
. Wait for grandmaster and time receiver ports to reach active states
|
|
. Wait for time receiver offset to converge
