3.10 ip domain-lookup

 Command: ip domain-lookup

 no ip domain-lookup

 Function: To enable/disable DNS function, whether the switch will send dynamic DNS

domain queries to the real DNS server or not.

 Parameter: None.

 Command Mode: Global Mode.

 Default: Disabled.

 Usage Guide: This command is used to enable or disable the switch DNS dynamic query

function. If DNS dynamic query function is enabled, the DNS server will resolve the host

name and domain name to the IPv4 or IPv6 address for requests from the clients. If DNS

is disabled, client applications will not be able to send any DNS requests to the DNS

server. In this situation, only the static address resolution is available. For the address

mapping in the resolve cache, which is learnt through DNS before, will be invalid after

aging.

 Example: To enable DNS function, can resolve the domain name dynamic.

 Switch(config)# ip domain-lookup
