Properties

(click to see Operations )

Name Data Type Permissions Description
quantumsize Read-write Amount of data to collect before the data is pushed to the crypto hardware for encryption. For large downloads, a larger quantum size better utilizes the crypto resources.

Default value: 8192

Possible values = 4096, 8192, 16384
crlmemorysizemb Read-write Maximum memory size to use for certificate revocation lists (CRLs). This parameter reserves memory for a CRL but sets a limit to the maximum memory that the CRLs loaded on the appliance can consume.

Default value: 256

Minimum value = 10

Maximum value = 1024
strictcachecks Read-write Enable strict CA certificate checks on the appliance.

Default value: NO

Possible values = YES, NO
ssltriggertimeout Read-write Time, in milliseconds, after which encryption is triggered for transactions that are not tracked on the Citrix ADC because their length is not known. There can be a delay of up to 10ms from the specified timeout value before the packet is pushed into the queue.

Default value: 100

Minimum value = 1

Maximum value = 200
sendclosenotify Read-write Send an SSL Close-Notify message to the client at the end of a transaction.

Default value: YES

Possible values = YES, NO
encrypttriggerpktcount Read-write Maximum number of queued packets after which encryption is triggered. Use this setting for SSL transactions that send small packets from server to Citrix ADC.

Default value: 45

Minimum value = 10

Maximum value = 50
denysslreneg Read-write Deny renegotiation in specified circumstances. Available settings function as follows
  • NO - Allow SSL renegotiation.
  • FRONTEND_CLIENT - Deny secure and nonsecure SSL renegotiation initiated by the client.
  • FRONTEND_CLIENTSERVER - Deny secure and nonsecure SSL renegotiation initiated by the client or the Citrix ADC during policy-based client authentication.
  • ALL - Deny all secure and nonsecure SSL renegotiation.
  • NONSECURE - Deny nonsecure SSL renegotiation. Allows only clients that support RFC 5746. Default value: ALL Possible values = NO, FRONTEND_CLIENT, FRONTEND_CLIENTSERVER, ALL, NONSECURE
    		•
    insertionencoding Read-write Encoding method used to insert the subject or issuer’s name in HTTP requests to servers.

    Default value: Unicode

    Possible values = Unicode, UTF-8
    ocspcachesize Read-write Size, per packet engine, in megabytes, of the OCSP cache. A maximum of 10% of the packet engine memory can be assigned. Because the maximum allowed packet engine memory is 4GB, the maximum value that can be assigned to the OCSP cache is approximately 410 MB.

    Default value: 10

    Minimum value = 0

    Maximum value = 512
    pushflag Read-write Insert PUSH flag into decrypted, encrypted, or all records. If the PUSH flag is set to a value other than 0, the buffered records are forwarded on the basis of the value of the PUSH flag. Available settings function as follows 0 - Auto (PUSH flag is not set.) 1 - Insert PUSH flag into every decrypted record. 2 -Insert PUSH flag into every encrypted record. 3 - Insert PUSH flag into every decrypted and encrypted record. Minimum value = 0 Maximum value = 3
    dropreqwithnohostheader Read-write Host header check for SNI enabled sessions. If this check is enabled and the HTTP request does not contain the host header for SNI enabled sessions(i.e vserver or profile bound to vserver has SNI enabled and ‘Client Hello’ arrived with SNI extension), the request is dropped.

    Default value: NO

    Possible values = YES, NO
    snihttphostmatch Read-write Controls how the HTTP ‘Host’ header value is validated. These checks are performed only if the session is SNI enabled (i.e when vserver or profile bound to vserver has SNI enabled and ‘Client Hello’ arrived with SNI extension) and HTTP request contains ‘Host’ header. Available settings function as follows CERT - Request is forwarded if the ‘Host’ value is covered by the certificate used to establish this SSL session. Note: ‘CERT’ matching mode cannot be applied in TLS 1.3 connections established by resuming from a previous TLS 1.3 session. On these connections, ‘STRICT’ matching mode will be used instead. STRICT - Request is forwarded only if value of ‘Host’ header in HTTP is identical to the ‘Server name’ value passed in ‘Client Hello’ of the SSL connection. NO - No validation is performed on the HTTP ‘Host’ header value. Default value: CERT Possible values = NO, CERT, STRICT
    pushenctriggertimeout Read-write PUSH encryption trigger timeout value. The timeout value is applied only if you set the Push Encryption Trigger parameter to Timer in the SSL virtual server settings.

    Default value: 1

    Minimum value = 1

    Maximum value = 200
    cryptodevdisablelimit Read-write Limit to the number of disabled SSL chips after which the ADC restarts. A value of zero implies that the ADC does not automatically restart.

    Default value: 0
    undefactioncontrol Read-write Name of the undefined built-in control action: CLIENTAUTH, NOCLIENTAUTH, NOOP, RESET, or DROP.

    Default value: “CLIENTAUTH”
    undefactiondata Read-write Name of the undefined built-in data action: NOOP, RESET or DROP.

    Default value: “NOOP”
    defaultprofile Read-write Global parameter used to enable default profile feature.

    Default value: DISABLED

    Possible values = ENABLED, DISABLED
    softwarecryptothreshold Read-write Citrix ADC CPU utilization threshold (in percentage) beyond which crypto operations are not done in software.

    A value of zero implies that CPU is not utilized for doing crypto in software.

    Default value: 0

    Minimum value = 0

    Maximum value = 100
    hybridfipsmode Read-write When this mode is enabled, system will use additional crypto hardware to accelerate symmetric crypto operations.

    Default value: DISABLED

    Possible values = ENABLED, DISABLED
    sigdigesttype <String[]> Read-write Signature Digest Algorithms that are supported by appliance. Default value is “ALL” and it will enable the following algorithms depending on the platform.

    Default value: DISABLED

    Possible values = ENABLED, DISABLED
    sslimaxerrorcachemem Read-write Specify the maximum memory that can be used for caching the learned data. This memory is used as a LRU cache so that the old entries gets replaced with new entry once the set memory limit is fully utilised. A value of 0 decides the limit automatically.

    Default value: 0

    Minimum value = 0

    Maximum value = 4294967294
    insertcertspace Read-write To insert space between lines in the certificate header of request.

    Operations

    (click to see Properties )

    • UPDATE
    • UNSET
    • GET (ALL)

    Some options that you can use for each operations:

    • Getting warnings in response: NITRO allows you to get warnings in an operation by specifying the 'warning' query parameter as 'yes'. For example, to get warnings while connecting to the NetScaler appliance, the URL is as follows:

      http:// <netscaler-ip-address> /nitro/v1/config/login?warning=yes

      If any, the warnings are displayed in the response payload with the HTTP code '209 X-NITRO-WARNING'.

    • Authenticated access for individual NITRO operations: NITRO allows you to logon to the NetScaler appliance to perform individual operations. You can use this option instead of creating a NITRO session (using the login object) and then using that session to perform all operations,

      To do this, you must specify the username and password in the request header of the NITRO request as follows:

      X-NITRO-USER: <username>

      X-NITRO-PASS: <password>

      Note: In such cases, make sure that the request header DOES not include the following:

      Cookie:NITRO_AUTH_TOKEN= <tokenvalue>
