Troubleshooting DNS Resolver Basic Operation ■ When the switch is configured with only the IP address of a DNS server available to the switch, then a DNS-compatible command, executed with a fully qualified domain name, can reach a device found in any domain accessible through the configured DNS server. ■ When the switch is configured with both of the following: • the IP address of a DNS server available to the switch • the domain suffix of a domain available to the configured DNS server then: • A DNS-compatible command that includes the host name of a device in the same domain as the configured domain suffix can reach that device. • A DNS-compatible command that includes a fully qualified domain name can reach a device in any domain that is available to the configured DNS server. Example. Suppose the switch is configured with the domain suffix mygroup.procurve.net and the IP address for an accessible DNS server. If an operator wants to use the switch to ping a target host in this domain by using the DNS name "leader" (assigned by a DNS server to an IP address used in that domain), then the operator can use either of the following commands: ProCurve# ping leader 10.28.229.220 is alive, time = 1 ms Host Name for the Desired Host Ping Response ProCurve# ping leader.mygroup.procurve.net 10.28.229.220 is alive, time = 1 ms Fully Qualified Domain Name for the Desired Host Ping Response Figure C-25. Example of Using Either a Host Name or a Fully Qualified Domain Name In the proceeding example, if the DNS server's IP address is configured on the switch, but a domain suffix is either not configured or is configured for a different domain than the target host, then the fully qualified domain name must be used.
