Usage Scenario
If the number of dynamic DNS entries in the domain name cache exceeds the maximum number allowed by the cache, a large amount of redundant data is generated. In this case, you can run the reset dns dynamic-host command to clear dynamic DNS entries stored in the domain name cache.
Precautions
The dynamic DNS entries cannot be restored after being cleared. Confirm the action before you use the command.
