Problem Solved. The issue was that the F5 had previously been configured with ntp servers. tmsh modify /sys ntp servers replace-all-with { 192.168.2.5 }

 

When the /etc/ntp.conf file was reviewed, we found the following entries: server 192.168.2.5 iburst and, because of following SOL14120: server 192.168.2.5 key 1 iburst

 

The NTPD grabbed and used the first such entry, which was NOT using a key for authentication. As such, the F5 unit was continually attempting to communicate to the ntp server without using authentication.

 

Solution: "tmsh modify /sys ntp servers none" followed by "tmsh save /sys config partitions all"
