Citrix NetScaler Release 9.3 Build 51.5
Enhancements in NetScaler 9.3 Build 51.5
The new Signature Editor allows users to customize signature rules and add their own signature rules to a signatures object, to meet the specific security
needs of their protected web sites and web services. Signature patterns, which define how a particular type of attack is detected, can be based on literal
strings, PCRE-format regular expressions, or the built-in SQL injection or cross-site scripting patterns. You can assign them to the default signature
categories, or create your own categories for ease of management. For more information on how to create and modify local signature rules, see the
In the configuration utility, in the ‘View Connections’ dialog box of the ‘Diagnostics’ page, the ‘Client-server’ check box has been renamed to
‘Client-Server Link Mapping’. When you select this check box, the dialo box displays all the linked client server mappings.
Load Balancing Virtual Server Entity Template
Now, when you export a load balancing entity template, a deployment file is created along with the entity template file. Both files are created in XML
format. The template file contains configuration-specific information and the deployment file contains deployment-specific information.
When you import the template file, you can either specify the deployment file or you can manually enter the deployment information. If you specify the
deployment file, the NetScaler appliance uses the deployment information in the deployment file.
NetScaler MPX 9700/10500/12500/15500 10G FIPS Appliances
SSL transactions per second (TPS) performance on the NetScaler MPX 9700/10500/12500/15500 10G FIPS appliances has significantly improved for
1024-bit and 2048-bit keys.
NetScaler MPX 11500/13500/14500/16500/18500 and SDX 11500/13500/14500/16500/18500 appliances (nCore only)
You can now convert a Citrix NetScaler MPX 11500/13500/14500/16500/18500 appliance to a Citrix NetScaler SDX appliance.

NetScaler SDX Appliance
The following table shows the maximum throughput available on the Citrix NetScaler SDX 11500/13500/14500/16500/18500 appliances.
Platform Maximum throughput (in Mbps)
SDX 11500 8000
SDX 13500 12000
SDX 14500 16000
SDX 16500 20000
SDX 18500 30000
The following new counters and SNMP OIDs measure the utilization of the Cavium
chip in SSL processing:
* Per device queue size
** BCM card:
**Old FIPS card
** NGFIPS card
** Cavium accel card
* Global q size
** counter: ssl_cur_q_size
** SNMP name: sslCurQSize
System (nCore, nCore VPX)
Support for the uniq tool, which is used to print the unique lines in a sorted file, has been included. The uniq tool is available in the shell interface.
Now you can set the cache memory size of a NetScaler VPX instance up to 8 GB.
To set the cache memory size of a VPX instance
1. Set the memory to the VPX instance. The minimum memory required for this instance for the basic functionality is 2 GB. To use large cache feature, you
have to increase the memory, for example, 14G [8G for Cache + 6G for PE and BSD]
2. On the VPX instance, add and apply the VPX-3000 license by either using the NS CLI or the configuration utility. This license allows you to set large cache
size (8 GB.)
3. Set the cache memory to the VPX instance by either using the NS CLI or the configuration utility.
4. Add a virtual disk to the VPX instance and set the size equal to 2.25 * VPX instance memory. For example, 32G [2.25*14].
5. Reboot the VPX instance.
