Overview of this book

With a large demand for responsive websites and availability of services, IT administrators are faced with an ever-rising need for services that are optimized for speed. NetScaler VPX is a software-based virtual appliance that provides users with the comprehensive NetScaler feature set. Implementing apps and cloud-based services is much easier with its increased service performance and integrated security features. This book will give you an insight into all the new features that NetScaler VPX™ has to offer. Starting off with the basics, you will learn how to set NetScaler up and configure it in a virtual environment including the new features available in version 11, such as unified gateway and portal theme customization. Next, the book will cover how to deploy NetScalar on Azure and Amazon, and you will also discover how to integrate it with an existing Citrix infrastructure. Next, you will venture into other topics such as load balancing Microsoft and Citrix solutions, configuring different forms of high availability Global Server Load Balancing (GSLB), and network optimization. You will also learn how to troubleshoot and analyze data using NetScaler's extensive array of features. Finally, you will discover how to protect web services using an application firewall and will get to grips with other features such as HTTP, DOS, and AAA.

Redundant Interface Sets

Redundant Interface Sets is a feature that allows us to have multiple interfaces connected but only one interface is active and the others are in standby mode. This enabled us to, for instance, have redundant network connections to different switches on, in case we want to have redundant NIC settings on NetScaler.

Unlike, for instance, LACP, where we need to configure the NetScaler and the peer device, this feature requires no configuration on the peer device. The only thing that the peer device needs to support is GARP broadcasts.

In case redundant interface sets are configured, only the active interface will accept traffic; the standby interface will drop any receiving traffic and will not send out any packets.

In case an active interface goes down, the second interface, which is based on a priority will broadcast a GARP containing its MAC address and where it is located, and will resume the traffic that was dropped from the primary interface.
