Disable TLS 1.0 and TLS 1.1 on NSIP

Navigate to Traffic Management > Load Balancing > Services.

On the Services page, click the Internal Services tab, select the check box next to the internal service for NSIP to be edited, and click Edit.

Note: There might be different services for NSIP for different secure ports. Make the required changes on all the applicable ports individually.

Click the pencil icon under SSL Parameters section to disable the required TLS.

Finally click OK and click Done.

Note: If the NetScaler appliance is in a high availability setup, the TLS must be disabled on both the nodes individually.
