Command Line Interface Reference for the ProSafe 7200 Series Layer-2 Switches, Software Ver- 4.5 DNS Client Commands The Domain Name System (DNS) is an Internet directory service. DNS is used to translate domain names to IP addresses. A DNS Client (often referred to as a resolver) uses a defined protocol to obtain resource data from name servers on its network. The DNS Client component must be globally enabled or disabled. When the client is enabled, it provides a hostname lookup service to other components in the switch. The client contacts one or more DNS servers to resolve a hostname to an IP address. The DNS servers list is configured by providing an IP address for each DNS name server, and server precedence is determined by the order in which the servers are added to this list. A default domain name can be configured, which defines the domain to use when performing a lookup on an unqualified hostname. Static hostname-to-address mappings can be added and removed from the local cache. The DNS client supports 128 entries in the DNS cache. Any application component requiring a DNS lookup may request services from the DNS client. When the DNS client is administratively disabled the local cache is purged. Changes to the name server configuration do not affect the cache. If a stacking switchover occurs, the new Master unit begins with a cleared cache. The following applications support domain name in addition to the IP address format: Radius DHCP Relay SNTP SNMP TFTP SYSLOG Ping UDP Relay Port and System Setup Commands v1.0, February 2007 4-25

DNS Client Commands

The Domain Name System (DNS) is an Internet directory service. DNS is used to translate

domain names to IP addresses. A DNS Client (often referred to as a resolver) uses a

defined protocol to obtain resource data from name servers on its network.

The DNS Client component must be globally enabled or disabled. When the client is

enabled, it provides a hostname lookup service to other components in the switch. The

client contacts one or more DNS servers to resolve a hostname to an IP address. The DNS

servers list is configured by providing an IP address for each DNS name server, and server

precedence is determined by the order in which the servers are added to this list. A default

domain name can be configured, which defines the domain to use when performing a

lookup on an unqualified hostname. Static hostname-to-address mappings can be added

and removed from the local cache.

The DNS client supports 128 entries in the DNS cache. Any application component

requiring a DNS lookup may request services from the DNS client. When the DNS client

is administratively disabled the local cache is purged. Changes to the name server

configuration do not affect the cache. If a stacking switchover occurs, the new Master unit

begins with a cleared cache.

The following applications support domain name in addition to the IP address format:

Radius

DHCP Relay

SNTP

SNMP

TFTP

SYSLOG

Ping

UDP Relay
