The following operations can be performed on "dns-profile":

show| add| set| rm| unset|

show dns profile

Displays the properties of the specified DNS profile. If profile name is not specified then all conifgured DNS profiles are displayed

Synopsis

show dns profile []

Arguments

dnsProfileName Name of the DNS profile

Output

dnsQueryLogging DNS query logging; if enabled, DNS query information such as DNS query id, DNS query flags , DNS domain name and DNS query type will be logged

dnsAnswerSecLogging DNS answer section; if enabled, answer section in the response will be logged.

dnsExtendedLogging DNS extended logging; if enabled, authority and additional section in the response will be logged.

dnsErrorLogging DNS error logging; if enabled, whenever error is encountered in DNS module reason for the error will be logged.

cacheRecords Cache resource records in the DNS cache. Applies to resource records obtained through proxy configurations only. End resolver and forwarder configurations always cache records in the DNS cache, and you cannot disable this behavior. When you disable record caching, the appliance stops caching server responses. However, cached records are not flushed. The appliance does not serve requests from the cache until record caching is enabled again.

cacheNegativeResponses Cache negative responses in the DNS cache. When disabled, the appliance stops caching negative responses except referral records. This applies to all configurations - proxy, end resolver, and forwarder. However, cached responses are not flushed. The appliance does not serve negative responses from the cache until this parameter is enabled again.

dropMultiQueryRequest Drop the DNS requests containing multiple queries. When enabled, DNS requests containing multiple queries will be dropped. In case of proxy configuration by default the DNS request containing multiple queries is forwarded to the backend and in case of ADNS and Resolver configuration NOCODE error response will be sent to the client.

cacheECSResponses Cache DNS responses with EDNS Client Subnet(ECS) option in the DNS cache. When disabled, the appliance stops caching responses with ECS option. This is relevant to proxy configuration. Enabling/disabling support of ECS option when Citrix ADC is authoritative for a GSLB domain is supported using a knob in GSLB vserver. In all other modes, ECS option is ignored.

Example

show dns profile [profile name]

add dns profile

Creates a DNS profile. These DNS profiles can be associated with DNS/DNS-TCP LB vservers ,ADNS/ADNS-TCP services , end resolvers and with DNS actions. DNS profiles dictate the caching and logging behavior for a DNS transaction.
