Arguments

quantumSize

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.

Possible values: 4096, 8192, 16384

Default value: 8192

crlMemorySizeMB

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

Enable strict CA certificate checks on the appliance.

Possible values: YES, NO

Default value: NO

sslTriggerTimeout

Time, in milliseconds, after which encryption is triggered for transactions that are not tracked on the NetScaler appliance 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

Send an SSL Close-Notify message to the client at the end of a transaction.

Possible values: YES, NO

Default value: YES

encryptTriggerPktCount

Maximum number of queued packets after which encryption is triggered. Use this setting for SSL transactions that send small packets from server to NetScaler.

Default value: 45

Minimum value: 10

Maximum value: 50

denySSLReneg

Deny renegotiation in specified circumstances. Available settings function as follows:

• NO - Allow SSL renegotiation.

• FRONTEND_CLIENTSERVER - Deny secure and nonsecure SSL renegotiation initiated by the client or the NetScaler 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.

Possible values: NO, FRONTEND_CLIENT, FRONTEND_CLIENTSERVER, ALL, NONSECURE

Possible values: Unicode, UTF-8

Default value: Unicode

ocspCacheSize

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

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:

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

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, the request is dropped.

Possible values: YES, NO

Default value: NO

pushEncTriggerTimeout

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

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

Minimum value: 0

undefActionControl

Name of the undefined built-in control action: CLIENTAUTH, NOCLIENTAUTH, NOOP, RESET, or DROP.

Default value: "CLIENTAUTH"

undefActionData

Name of the undefined built-in data action: NOOP, RESET or DROP.

Default value: "NOOP"

defaultProfile

Global parameter used to enable default profile feature.

Possible values: ENABLED, DISABLED

Default value: DISABLED

softwareCryptoThreshold

Netscaler 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

When this mode is enabled, system will use additional crypto hardware to accelerate symmetric crypto operations.

Possible values: ENABLED, DISABLED

Default value: DISABLED

sigDigestType

Signature Digest Algorithms that are supported by appliance. Default value is "ALL" and it will enable the following algorithms depending on the platform.

On VPX: RSA-MD5 RSA-SHA1 RSA-SHA224 RSA-SHA256 RSA-SHA384 RSA-SHA512 DSA-SHA1 DSA-SHA224 DSA-SHA256 DSA-SHA384 DSA-SHA512

Others: RSA-MD5 RSA-SHA1 RSA-SHA224 RSA-SHA256 RSA-SHA384 RSA-SHA512.

Default value: ALL

ssliErrorCache

Enable or disable dynamically learning and caching the learned information to make the subsequent interception or bypass decision. When enabled, NS does the lookup of this cached data to do early bypass.

Possible values: ENABLED, DISABLED

Default value: DISABLED

ssliMaxErrorCacheMem

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

To insert space between lines in the certificate header of request

Possible values: YES, NO

Default value: YES

unset ssl parameter
