Video - Cisco Nexus 1000V v1.5 Installation
The Cisco Nexus 1000V is compatible with any upstream physical access layer switch that is Ethernet standard compliant, including the Catalyst 6500 series switch, Cisco Nexus switches, and switches from other network vendors. The Cisco Nexus 1000V is compatible with any server hardware listed in the VMware Hardware Compatibility List (HCL). Cisco and VMware jointly designed APIs that produced the Cisco Nexus 1000V. The Cisco Nexus 1000V is a distributed virtual switch solution that is fully integrated within the VMware virtual infrastructure, including VMware vCenter for the virtualization administrator. This solution offloads the configuration of the virtual switch and port groups to the network administrator to enforce a consistent data center network policy. In this release Java applications are introduced for VSM and VEM installation.
For the Virtual Supervisor Module (VSM)โThe control plane of the switch and a virtual machine that runs Cisco NX-OS, just download the Nexus1000v.4.2.1.SV1.5.1.zip file and enter the following command from a Windows, Linux, or Mac command prompt:
java -jar zip_file_location/Nexus1000v.4.2.1.SV1.5.1/VSM/Installer_App/Nexus1000V-install.jar VSM
For the Virtual Ethernet Module (VEM)โA virtual line card embedded in each VMware vSphere (ESX) host. The VEM is partly inside the kernel of the hypervisor and partly in a user-world process, called the VEM Agent. Enter the following command from a Windows, Linux, or Mac command prompt:
java -jar zip_file_location/Nexus1000v.4.2.1.SV1.5.1/VSM/Installer_App/Nexus1000V-install.jar VEM

Technical Whitepaper - Scalable Cloud Network with Cisco Nexus 1000V Series Switches and VXLAN
Many customers are building private or public clouds. Intrinsic to cloud computing is having multiple tenants with numerous applications using the cloud infrastructure. Each of these tenants and applications needs to be logically isolated from each other, even at the networking level. For example, a three-tier application can have multiple virtual machines requiring logically isolated networks between the virtual machines.
Traditional network isolation techniques such as IEEE 802.1Q VLAN provide 4096 LAN segments (via a 12-bit VLAN identifier) and may not provide enough segments for large cloud deployments. Cisco and a group of industry vendors are working together to address new requirements of scalable LAN segmentation as well as transporting virtual machines across a broader diameter.
The underlying technology, referred to as Virtual Extensible LAN (or VXLAN), defines a 24-bit LAN segment identifier to provide segmentation at cloud scale. In addition, VXLAN provides an architecture for customers to grow their cloud deployments with repeatable pods in different subnets. VXLAN can also enable virtual machines to be migrated between servers in different subnets. With Cisco Nexusยฎ 1000V Series Switches supporting VXLAN, customers can quickly and confidently deploy their applications to the cloud.
