Usage Guideline
The system supports the DNS caching name server function. When the caching name server function is
enabled and IP domain-lookup, the system forwards the DNS query packet to the configured name server.
The answer replied by the name server will be cached and used to answer the subsequent queries.
Example
This example shows how to enable the DNS caching name server function.
Switch# configure terminal
Switch(config)# ip dns server
Switch(config)#
31-3 ip dns lookup
This command is used to enable DNS searching dynamic cached or static created host entries. Use the

Command Mode
Global Configuration Mode.
Command Default Level

Usage Guideline
When the system tries to lookup a domain name, by default, it will look in the static and dynamic cache
first and then send a query to the name server if no matching entries were found. Use this command to
disable the lookup option of static or dynamic cache entries before sending requests to the name server.
If this command is used without options, then the static and cache options are enabled or disabled at the
same time.
Example
This example shows how to enable the lookup of a static host for answering the request.
Switch# configure terminal
Switch(config)# ip dns lookup static
(Optional) Specifies to enable or disable the lookup of static entries
before asking the name server.
(Optional) Specifies to enable or disable the lookup of the dynamic
cache before asking the name server.
