Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Text:	.Users can manage the `chrony` interleaved mode, NTP filtering, and hardware timestamping With this update, the `timesync` RHEL System Role enables you to configure the Network Time Protocol (NTP) interleaved mode, additional filtering of NTP measurements, and hardware timestamping. The `chrony` package of version 4.0 adds support for these functionalities to achieve a highly accurate and stable synchronization of clocks in local networks. * To enable the NTP interleaved mode, make sure the server supports this feature, and set the `xleave` option to `yes` for the server in the `timesync_ntp_servers` list. The default value is `no`. * To set the number of NTP measurements per clock update, set the `filter` option for the NTP server you are configuring. The default value is `1`. * To set the list of interfaces which should have hardware timestamping enabled for NTP, use the `timesync_ntp_hwts_interfaces` parameter. The special value `["*"]` enables timestamping on all interfaces that support it. The default is `[]`.	Story Points:	---

@mlichvar Please check the Doc Text and make sure I got it right.

Comment 2 Miroslav Lichvar 2021-03-15 08:31:40 UTC

It looks good to me. I added a sentence to explain that the server needs to support the interleaved mode.

Comment 6 Rich Megginson 2021-04-02 00:04:11 UTC

Test coverage is tests/tests_ntp.yml
