Issue

DNS is never cached when doing domain tunnel for user of a trusted domain
BUG has been raised to address this behaviour as it generates excessive DNS requests traffic between the DATA SVM and the DNS server.
ONTAP does a live lookup every single time a trusted domain user hits the tunnel, this is by design. 
No fix has been provided as this is expected behaviour
RFE to cache these DNS requests generated while a user of a trusted domain connects to the domain tunnel
