DNS Service
Parameters

IP Services

This chapter describes the following IP services:
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 for attached host devices, including
DHCP option 82 information, and defines the servers to which client requests
are forwarded.
DHCP Dynamic Provision
Note:
For information on DHCP snooping which is included in this folder, see
"DHCP Snooping" on page
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.
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
on page
440).
If one or more name servers are configured, but DNS is not yet enabled and the
switch receives a DHCP packet containing a DNS field with a list of DNS servers,
– Enables dynamic provision via DHCP.
