11.2.3.5 Managing DNS Relay
11.2.3.5.1. Configuring DNS Relay
The DNS protocol controls the Domain Name System (DNS), a distributed database with which
you can map host names to IP addresses. When you configure DNS on your switch, you can
substitute the host name for the IP address with all IP commands, such as ping, telnet,
traceroute, and related Telnet support operations. To keep track of domain names, IP has
defined the concept of a domain name server, which holds a cache (or database) of names
mapped to IP addresses. To map domain names to IP addresses, you must first identify the
host names, specify the name server that is present on your network, and enable the DNS.
Configurable Data
Admin Mode - Select enable or disable from the pull down menu. When you select
'enable', the IP Domain Naming System (DNS)-based host name-to-address translation
will be enabled.
Default Domain Name - Default domain name used to complete unqualified host names.
Do not include the initial period that separates an unqualified name from the domain
name. This is a text string of up to 64 characters.
Command Buttons
Submit - Send the updated configuration to the switch. Configuration changes take effect
immediately. These changes will not be retained across a power cycle unless a save is
performed
