Description

The chrony service fails to start when attempting to configure an interface for hardware timestamping that doesn't support it. This is expected, but there should be a graceful error message.

vyos@vyos# set service ntp timestamp interface eth0 receive-filter all
vyos@vyos# commit
Job for chrony.service failed because the control process exited with error code.
See "systemctl status chrony.service" and "journalctl -xeu chrony.service" for details.
vyos@vyos# ethtool -T eth0
Time stamping parameters for eth0:
Capabilities:
        software-transmit
        software-receive
        software-system-clock
PTP Hardware Clock: none
Hardware Transmit Timestamp Modes: none
