This chapter describes how to configure Domain Name Service (DNS) and a
DHCP client identifier for the switch. For information on DHCP snooping
which is included in this folder, see "DHCP Snooping" on page 412 .
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 Client – Specifies the DHCP client identifier for an interface.
◆
DHCP Relay – Enables DHCP relay service, and defines the servers to
which client requests are forwarded.
◆
PPPoE Intermediate Agent – Configures PPPoE Intermediate Agent
(PPPoE IA) relay parameters required for passing authentication
messages between a client and broadband remote access servers.

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.
