Prerequisites

•Understanding Private VLANs8

•Cisco Systems' Private VLANs: Scalable Security in a Multi-Client Environment9

•Private VLAN (PVLAN) on vNetwork Distributed Switch - Concept Overview (1010691)10

16.25.2. Prerequisites

•Use a PVLAN supported switch.

See Private VLAN Catalyst Switch Support Matrix11for more information.

•All the layer 2 switches, which are PVLAN-aware, are connected to each other, and one of them is connected to a router. All the ports connected to the host would be configured in trunk mode. Open Management VLAN, Primary VLAN (public) and Secondary Isolated VLAN ports. Configure the switch port connected to the router in PVLAN promiscuous trunk mode, which would translate an isolated VLAN to primary VLAN for the PVLAN-unaware router.

Note that only Cisco Catalyst 4500 has the PVLAN promiscuous trunk mode to connect both normal VLAN and PVLAN to a PVLAN-unaware switch. For the other Catalyst PVLAN support switch, connect the switch to upper switch by using cables, one each for a PVLAN pair.

•Configure private VLAN on your physical switches out-of-band.

•Before you use PVLAN on XenServer and KVM, enable Open vSwitch (OVS).

Note

OVS on XenServer and KVM does not support PVLAN natively. Therefore, CloudPlatform managed to simulate PVLAN on OVS for XenServer and KVM by modifying the flow table.

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
