Troubleshooting DNS
Symptom
After enabling the dynamic domain name resolution, the user cannot get the correct IP address.
Solution
z Use the display dns dynamic-host command to check 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 exists in the cache but the IP address is incorrect, check that the DNS
client has the correct IP address of the DNS server.
z Check that the mapping between the domain name and IP address is correct on the DNS server.
