dns-profile
The following operations can be performed on “dns-profile”:
| add | rm | set | show | unset |
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.
Synopsis
add dns profile
Arguments
dnsProfileName Name of the DNS profile
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
Possible values: ENABLED, DISABLED Default value: DISABLED
dnsAnswerSecLogging DNS answer section; if enabled, answer section in the response will be logged.
Possible values: ENABLED, DISABLED Default value: DISABLED
dnsExtendedLogging DNS extended logging; if enabled, authority and additional section in the response will be logged.
Possible values: ENABLED, DISABLED Default value: DISABLED
dnsErrorLogging DNS error logging; if enabled, whenever error is encountered in DNS module reason for the error will be logged.
Possible values: ENABLED, DISABLED Default value: DISABLED
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.
Possible values: ENABLED, DISABLED Default value: ENABLED
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.
Possible values: ENABLED, DISABLED Default value: ENABLED
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.
Possible values: ENABLED, DISABLED Default value: DISABLED
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.
Possible values: ENABLED, DISABLED Default value: DISABLED
Example
add dns profile testprofile -caching yes
rm dns profile
Removes the specified DNS profile from the Citrix ADC
Synopsis
rm dns profile
Arguments
dnsProfileName Name of the DNS profile to be removed.
Example
rm dns profile testprofile
set dns profile
Modifies the attributes of a DNS profile.
Synopsis
set dns profile
Arguments
dnsProfileName Name of the DNS profile
