This chapter describes how to configure Domain Name Service (DNS) on
this switch. For information on DHCP snooping which is included in this
folder, see "DHCP Snooping" on page 342.
DNS service on this switch allows host names to be mapped to IP
addresses using static table entries or by redirection to other name servers
on the network. When a client device designates this switch as a DNS
server, the client will attempt to resolve host names into IP addresses by
forwarding DNS queries to the switch, and waiting for a response.
You can manually configure entries in the DNS table used for mapping
domain names to IP addresses, configure default domain names, or specify
one or more name servers to use for domain name to address translation.
CONFIGURING GENERAL DNS SERVICE PARAMETERS
Use the IP Service > DNS - General (Configure Global) page to enable
domain lookup and set the default domain name.
