The set dns command enables you to control the DNS cache. You can flush the cache file of a DNS view or flush a particular entry from a cache file. You can also flush a specific domain and its subdomains from the DNS cache. In addition, you can schedule an inbound zone transfer from an external primary server. This command displays IDN data in punycode. You can also use this command to delete cache files from the default DNS view for DNS cache acceleration on IB-FLEX.
