Hi, I have set a default root on the TMOS (to reach my DNS server). When the management interface is down, I ping my DNS server on the command line,the DNS server is reachable.I use nslookup to resolve the domain "www.f5.com" on the command line,it is successful.But RESOLV::lookup don't work. Then I create a volume and install 12.0.0 software,then switch default boot volume to the volume. RESOLV::lookup can work on 12.0.0 software version.I don't do any other settings.Why? I think whether it is a bug of 11.6.0 software.
