15 IP Services
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 346.
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.
◆ Multicast DNS – Configures multicast DNS host name-to-address mapping on
the local network without the need for a dedicated DNS server.
◆ DHCP Client – Specifies the DHCP client identifier for an interface.
◆ DHCP Relay Option 82 – Enables DHCP relay service for attached host devices,
including DHCP option 82 information.
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.
Command Usage
◆ To enable DNS service on this switch, enable domain lookup status, and
configure one or more name servers (see “Configuring a List of Name Servers”
on page 456).
