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 - 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.
