The document provides an overview of troubleshooting methodology for VMware NSX. It discusses that NSX implements logical switching and routing services on top of an IP transport network. The key things to check when troubleshooting include validating the IP transport connectivity using tools like ping, and examining the VTEP tables and MAC tables on the NSX controller and hosts for a given virtual network identifier (VNI) to understand virtual machine connectivity and forwarding. An example is provided where pinging between VMs populates the MAC tables on hosts, demonstrating how NSX forwarding works based on these tables.

This document discusses troubleshooting VXLAN and network services in a virtualized environment using VMware NSX. It covers VXLAN packet flow, NSX enhancements to the data and control planes, configuration and consumption demos, packet walks in unicast mode, troubleshooting demos using NSX Manager tools, dynamic routing details and demos, and network virtualization operations. The key takeaways are that multicast is not required in the physical network for VXLAN, NSX provides tools to troubleshoot networks and services, and NSX integrates with operations tools for analysis and alerting.

VMware NSX is a network virtualization and security platform that provides logical switching, routing, firewalling, and load balancing capabilities. It emerged from VMware's acquisition of Nicira. NSX for vSphere is deployed most often as it integrates natively with VMware platforms like vCenter. The NSX architecture consists of edge nodes, controllers, and a manager to program the hypervisor kernel modules that implement the distributed data, control, and management planes. Key NSX components provide distributed logical routing, switching, and firewalling at the hypervisor level for scalability. The NSX edge services gateway delivers integrated network functions like firewall, VPN, and load balancing as virtual appliances.

This document introduces programmable virtual networks and discusses their advantages over traditional network slicing. It describes FlowVisor, an early network slicing tool, and its limitations in providing full network virtualization.

Analogous to server virtualization, Network Virtualization decouples and isolates virtual networks (i.e. tenant) from the underlying network hardware. One of the key value propositions of Software-Defined Networking (SDN) is to enable the provisioning and operation of virtual networks. This tutorial motivates the need for network virtualization, describes the high-level requirements, provides an overview of all architectural approaches, and gives you a clear picture of the vendor landscape. Previously presented at ONUG Fall 2013 and Spring 2014.

Software Defined Networking is seeing a lot of momentum these days. With server virtualization solving the virtual machines problem, and large scale object storage solving the distributed storage challenge, SDN is seen as key in virtual networking. In this talk we don't try to define SDN but rather dive straight into what in our opinion is the core enabled of SDN: the virtual switch OVS. OVS can help manage VLAN for guest network isolation, it can re-route any traffic at L2-L4 by keeping forwarding tables controlled by a remote controller (Openfow controller). We show these few OVS capabilities and highlight how they are used in CloudStack and Xen. Xen Summit presentation of CloudStack and Software Defined Networks. OpenVswitch is the default bridge in Xen and supported in XenServer and Xen Cloud Platform
