[Hi Looking a easy understandable guide document that can help for writing the policy expression for content switch / rewrite . or any training specific this type of content]

Hi, does the following not give you the information you require?

[Hi Looking a easy understandable guide document that can help for writing the policy expression for content switch / rewrite . or any training specific this type of content]

If you're wanting formal training the would recommend CNS-224 Implement Citrix ADC 13.x with Traffic Management, which is available either as On-Demand or Instructor-Led and covers everything from policy overview to advanced expressions etc.

Alternatively you could review the Configuring advanced policy expression: getting started documents ref: https://docs.netscaler.com/en-us/citrix-adc/current-release/appexpert/policies-and-expressions/adv-policy-expressions-getting-started.html

[Upgrading from NS11.0 to 12.1, can it be done?]

Hi, I would also recommend reviewing the VPX compatibility matrix to ensure that the underlying infrastructure is also supported ref: https://docs.netscaler.com/en-us/citrix-adc/current-release/deploying-vpx/supported-hypervisors-features-limitations.html.

[Customization of web page]

Hi, if you can expand on the question as if it's related to Gateway portal then the recommendations are to use the portal theme options within the GUI ref: https://docs.netscaler.com/en-us/citrix-gateway/current-release/gateway-portal-customization/admin-ui-portal-customizations.html.

[Hello team: I need a matrix of NetScaler editions, on the web I can only find the datasheet but not a matrix of editions and functionalities, could you please help me? Regards]

Is there a specific feature you need to check that's available on Advanced as Premium will include all features?

[How do I use ADM to extract specific statements from the ADC configs?]

Hi, if this is certificate related then have you tried going into the Infrastructure > SSL Dashboard > SSL Certificates-Used page as this will detail all the SSL certificates and where used.

If you're wanting to update the SSL certificate then this can also be completed within the Infrastructure > SSL Dashboard > SSL Certificates - Expiring within one week and 30 days option, although this would need to be repeated for each NetScaler pair.

[Use Content Switching to filter and allow certain hostname on a Virtual service]

To add to this, using pattern set functionality will result in a less resource-intensive expressions matching process 😉

[Hello, What is the best way to construct nFactor EPA pre auth expressions for both macOS and Windows?]

I'd also suggest reviewing the following article related to troubleshooting https://support.citrix.com/article/CTX209148/understanding-and-configuring-epa-verbose-logging-on-citrix-gateway as this will allow you to perform your own testing whilst reviewing the client EPA logs.

[How to monitor the uptime of a Citrix gateway VPN vserver?]

Depending on the information required, it may be possible to use ADM and report in the status change with subsequent notification (ADM Event / Rules) relating to the corresponding ADC / vserver.

The screenshot below from ADM details the event created when the status changes on a vserver (this was a Gateway).

[Are Citrix Gateway and Citrix ADC same or different?]

One item to note is that ICA Only mode set on the Gateway virtual server, as this can be one of two modes.

1. ICA Only - When set to ON, it implies Basic mode where the user can log on using either Citrix Receiver or a browser and get access to the published apps etc.
2. ICA Only - When set to OFF, it implies Smart Access mode where the user can log on using either Citrix Receiver or a browser or a Citrix Gateway Plug-in (aka VPN or Clientless Access).

Depending on which option is required, you may want to check how many concurrent users you're going to have as option 1 is unlimited (dependant on appliance capabilities) whereby option 2 has a license count depending on edition (1,000 for Advanced Edition or Unlimited for Premium, again dependant on appliance capabilities).

[NetScaler ns.log 101 question.. Why did my NetScaler HA failover?]

Hi,

Within ADM you should see the corresponding event log which may give you an indication of the failure (screenshot details lost heartbeat etc.).
