Figure 9. Example of Viewing the Current DNS Configuration
Operating Notes
■ The DNS server must be accessible to the switch, but it is not necessary for any intermediate
devices between the switch and the DNS server to be configured to support DNS operation.
■ A DNS configuration must include the IP address for a DNS server that is able to resolve host
names for the desired domain. If a DNS server has limited knowledge of other domains, then
its ability to resolve ping or traceroute requests is also limited.
■ If the DNS configuration includes a DNS server IP address but does not also include a domain
suffix, then any ping or traceroute command should include the target host’s fully qualified
domain name. Refer to Figure 3 on page 29.
■ The switch supports one DNS entry; that is, one DNS server IP address and the corresponding
domain name suffix.
■ Switch-Initiated DNS packets go out through the VLAN having the best route to the DNS
server, even if a Management VLAN has been configured.
■ The traceroute command output shows only IP addresses.
■ The DNS server address must be manually input. It is not be automatically determined via
DHCP.
■ Operation with IPv4 DNS servers has been verified and, while no problems with servers
supporting both IPv4 and IPv6 addresses are expected, testing has not been performed with
such servers. (IPv6 AAAA-style queries are not supported.)
