IP Services
In this chapter
This chapter describes how to configure Domain Name Service (DNS) and DHCP Relay Service. For
information on DHCP snooping which is included in this folder, see
“DHCP Snooping” on page 903.
This chapter provides information on the following IP services, including:
• DNS – Configures default domain names, identifies servers to use for dynamic lookup, and
shows how to configure static entries.
• DHCP – Enables DHCP relay service, and defines the servers to which client requests are
forwarded.
Domain Name Service
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.
