1.6 Troubleshooting DNS Configuration
I. Symptom
After enabling the dynamic domain name resolution, the user cannot get the correct IP
address.
II. Solution
z Use the display dns dynamic-host command to verify that the specified domain
name is in the cache.
z 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.
z 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.
z Verify the mapping between the domain name and IP address is correct on the
DNS server.
