Cisco 3750

• All VLANs (300-999) are passed to all the pod-level layer-2 switches.

14.3.2. Cisco 3750

The following steps show how a Cisco 3750 is configured for zone-level layer-3 switching. These steps assume VLAN 201 is used to route untagged private IPs for pod 1, and pod 1’s layer-2 switch is connected to GigabitEthernet1/0/1.

1.Setting VTP mode to transparent allows us to utilize VLAN IDs above 1000. Since we only use VLANs up to 999, vtp transparent mode is not strictly required.

vtp mode transparent

vlan 200-999

exit

2. Configure GigabitEthernet1/0/1.

interface GigabitEthernet1/0/1

switchport trunk encapsulation dot1q

switchport mode trunk

switchport trunk native vlan 201

exit

The statements configure GigabitEthernet1/0/1 as follows:

VLAN 201 is the native untagged VLAN for port GigabitEthernet1/0/1.

Cisco passes all VLANs by default. As a result, all VLANs (300-999) are passed to all the pod-level layer-2 switches.

14.4. Layer-2 Switch

The layer-2 switch is the access switching layer inside the pod.

It should trunk all VLANs into every computing host.

It should switch traffic for the management network containing computing and storage hosts. The layer-3 switch will serve as the gateway for the management network.

Example Configurations

This section contains example configurations for specific switch models for pod-level layer-2 switching. It assumes VLAN management protocols such as VTP or GVRP have been disabled. The scripts must be changed appropriately if you choose to use VTP or GVRP.

14.4.1. Dell 62xx

The following steps show how a Dell 62xx is configured for pod-level layer-2 switching.

1. Configure all the VLANs in the database.

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.
