1.6 Troubleshooting DNS Configuration

I. Symptom
After enabling the dynamic domain name resolution, the user cannot get the correct IP
address.
II. Solution
Use the display dns dynamic-host command to verify that the specified domain
name is in the cache.
If there is no defined domain name, check that dynamic domain name resolution is
enabled and the DNS client can communicate with the DNS server.
If the specified domain name is in the cache, but the IP address is incorrect, check
that the DNS client has the correct IP address of the DNS server.
Verify the mapping between the domain name and IP address is correct on the
DNS server.
