When NTP symmetric key authentication is configured, as per https://support.f5.com/csp/article/K14120, and the BIG-IP is part of a device service cluster, then a warning similar to this will be seen periodically in /var/log/ltm: warning mcpd[6317]: 01071af0:4: NTP not configured on device 1.2.3.4 - within a trust
Incorrect NTP warnings are seen periodically in /var/log/ltm.
- NTP symmetric key authentication must be configured. - The BIG-IP must be part of a device service cluster. - Non-authenticated NTP servers must not be in-use.
There is no workaround at this time.
Prevented this warning from being emitted when NTP symmetric key authentication is in-use in a device service cluster.
