A DNS query is not sent for configured FQDN nodes until the TTL value expires.


Name addresses do not resolve to IP addresses until the TTL expires.


This occurs when 'load sys config' is executed.


You can use either of the following workarounds: -- Change the default TTL value to be fewer than 300 seconds (the default value is 3600 seconds). -- Restart dynconfd daemon: tmsh restart sys service dynconfd
