Likewise, integrations with third party vendors, such as Palo Alto Networks, Symantec and F5, are not covered here.Installation of NSX for vSphereThis section guides you through the step-by-step installation, configuration and validation of a new NSX for vSph ere (“NSX-v”) deployment.Infrastructure requirements for NSX-vVMware elements:Prior to installing NSX for vSphere, you must deploy:∙vCenter 5.5 with:∙one or more Compute clusters∙Management and Edge cluster∙two or more ESXi 5.5 in each clusterEach ESXi host has the following characteristics:∙Server hardware is listed on the VMware HCL for vSphere 5.5∙2x Quad Core x86_64 compatible CPUs with a speed of 2Ghz or greater, plus hardware-assisted virtualization support (total of 8 physical cores)∙32GB of RAM or greater∙2x Physical NICs∙Either 5GB of Local Disk/Dedicated boot from SAN LUN or supported ESXi embedded device (USB/SD). Local Disk is not required if vSphere Auto Deploy is used.Figure 2 – Infrastructure for NSXFor resource constraints, this lab uses only one Compute Cluster, as shown in the following screenshots.Network fabric:Configure at least 1600 byte of MTU frame sizes on all the physical switches/routers between ESXi.vCenter:Clusters:∙One Compute Cluster “Cluster-CompA” with two ESXi.∙One Mana gement + Edge Cluster “Cluster-Mgt_Edge” with two ESXi.Figure 3 – vCenter Host ViewNetworking:∙Virtual Standard Switch (vSS) for Cluster-CompA and Cluster-Mgt_Edge:∙Management: This vSS is used for the ESXi-Compute and ESXi-Mgt_Edge management.Interface to use: The interface of the ESXi in Cluster-CompA + Cluster-Mgt_Edge on theManagement network is used.∙Virtual Distributed Switch (vDS) for Cluster-CompA:∙vDS-CompA: This vDS will be used for the VM production traffic. Interface to use: The interface of the ESXi in Cluster-CompA on the Transport network is used. Note: No ESXi IP@ isconfigured yet.∙Virtual Distributed Switch (vDS) for Cluster-Mgt_Edge:∙vDS-Mgt_Edge: This vDS will be used for the VM production traffic. Interface to use: The interface of the ESXi in Cluster-Mgt_Edge on the Transport network is used. Note: No ESXi IP@ is configured yet. Note2: Create a Management Network for the future logical routers“LogicalRouter_Mgt”∙vDS-External: This vDS will be used to talk to the physical external network. Interface to use: The interface of the ESXi in Cluster-Mgt_Edge on the External network is used. Note: No ESXi IP@ is configured.Figure 4 – vCenter Networking ViewNSX-v Installation overviewIn this step, you’ll deploy the NSX Manager and NSX Controller Nodes:Figure 5 – NSX elementsStep 1: Install NSX ManagerThe NSX Manager is the centralized management component of NSX, and runs as a virtual appliance on an ESX host.1.Install NSX Manager: From vCenter Home-> Hosts and Clusters, select Cluster-Mgt_Edge andDeploy OVF TemplateFigure 6 – Installation NSX Manager2.Register NSX Manager with vCenter: Log in NSX Manager and from NSX Manager Manage ->NSX Management Services, register to vCenterFigure 7 – NSX Manager registration to vCenter3.Validate registration: Log out of vCenter if already logged in. And re-log in with root (required toget the NSX plugin installed in vCenter). Note: The first login can take a few minutes. After registration, you will see the Network & Security plugin in the Inventory:Figure 8 – NSX plugin in vCenterStep 2: Install the NSX Controller ClusterThe NSX Controller Cluster is a distributed state management system that controls virtual networks and overlay transport tunnels1.Install the first NSX Controller Node: From NSX Home -> Installation, add first NSX ControllerNode.Figure 9 – First NSX Controller Node installationThe IP Pool “NSX Controller Cluster” has been created with the following settings:Figure 10 – NSX Controller Cluster IP pool2.Validate the installation of first NSX Controller Node: The deployment of an NSX ControllerNode can take few minutes.Figure 11 – First NSX Controller Node deployedNote: In rare cases, the Controller takes too long install and is automatically deleted. In such cases, you can install a DHCP server in the Controller’s subnet to speed up its installation. That DHCP server can be configured with fake IP addresses since the Controller will still get its IP address from the NSX IP Pool.3.Install the second and third NSX Controller Nodes:Note: You can run with only one NSX Controller in a lab (not supported in a production setting), but this will render you unable to test Controller Node high-availability. For a productiondeployment or to test high-availability, you must install a total of three Controller Nodes.From NSX Home -> Installation, add second and third NSX Controller NodesFigure 12 – Second and third NSX Controller Nodes installation4.Validate installation of all three NSX Controller NodesFigure 13 –NSX Controller Cluster deployedStep 3: Prepare ESXi hosts for NSXTo provide all the NSX services, special kernel modules and user space tools have to be installed on the ESXi hosts.1.Install NSX elements on cluster hosts: From NSX Home -> Installation-> Host Preparation,click Install for all the clusters:Figure 14 –Installation of NSX elements on cluster hosts2.Check the installation of NSX elements on cluster hostsFigure 15 – Validation of installation of NSX elements on clusters hosts3.Configure the VXLAN VTEP interface for Cluster-CompA hosts: From NSX Home ->Installation-> Host Preparation, click Configure for the Cluster-CompA:Figure 16 – Configuration of VTEP interface for Cluster-CompA hostsFigure 17 – Configuration of VTEP IP@ pool for the Cluster-CompA hosts4.Validate the VTEP configuration on the Cluster-CompA hosts.

Note: Since NSX 6.0 with ESXi 5.5, multicast support is no longer required on the physical fabric.Figure 23 – View of the VTEP IP@ allocated to each Cluster hosts9.Configure a Transport Zone: The transport zone is the compute diameter of your cloud. You wantall your ESXi hosts to participate to your cloud. From NSX Home -> Installation-> LogicalNetwork Preparation -> Transport Zone, click +. Note: Since NSX 6.0 with ESXi 5.5, multicastsupport is no longer required on the physical fabric.Figure 24 – Creation of the Transport Zone that spans among all ClustersThis completes the installation of the NSX-v elements of your deployment. Proceed to the logical switch set-up steps in the next section.L2 Logical SwitchingGoal of the L2 logical switching labIn this section, you will create Logical Switches.Figure 25 – Logical View Logical SwitchesCreate four Logical SwitchesFrom NSX Home -> Logical Switches, create four Logical Switches called: ∙Transit-Network-01∙Web-Tier-01∙App-Tier-01∙DB-Tier-01Figure 26 –Logical Switch creationNote: You will notice that one vDS Port Group is automatically created for each Logical Switch. From vCenter Home -> NetworkingFigure 27 –vDS Port Groups created for each logical switchAdd VMs on Web/App/DB Logical SwitchesYou have VMs on the different Cluster-CompA hosts:Figure 28 – VMs in Cluste-CompAFrom NSX Home -> Logical Switches, add VMs to the appropriate logical switchFigure 29 – Add VMs onLlogical SwitchFigure 30 – Select VMsNote: You can check the VMs are connected to the correct Logical Switch on vCenter too: From vCenter Home -> Hosts and Clusters, look at the VM HardwareFigure 31 – Validate VM Network adapter is connected to vDS port groupValidate that VMs on the same Logical Switch can communicateFigure 32 – ping between Web VMsNote: The VM traffic flow in the fabric is:Figure 33 – Logical Switch traffic flowDistributed Logical RoutingGoal of the logical routing labIn this step, you’ll create a Distributed Logical Router.Figure 34 – Logical View Distributed Logical RouterCreate a single Distributed Logical RouterFrom NSX Home -> NSX Edges, create a Distributed Logical Router with four interfaces (LIFS) ∙Uplink to Transit-Network-01 with an IP of 172.16.1.2/29∙Internal connected to Web-Tier-01 Logical Switch with IP 10.0.1.1/24∙Internal connected to App-Tier-01 Logical Switch with IP 10.0.2.1/24∙Internal connected to DB-Tier-01 Logical Switch with IP 10.0.3.1/24Figure 35 – Logical Distributed Router creation, first paneFigure 36 – Logical Distributed Router creation, second paneFigure 37 – Logical Distributed Router creation, third paneNote: One Management Interface must be configured. This interface is to access the Logical Router Control VM via SSH for management/troubleshooting (t he VM production traffic doesn’t reac h the Logical Router Control VM - see Figure 39 and Figure 40). For SSH access, configure a management IP address (not shown in the screenshot above).Validate that VMs in the different Logical Switches can communicateFigure 38 – ping between Web and App VMNote: The Logical Router Control VM (in the Mgt_Edge Cluster) is not involved in the L3 VM traffic flow.The VM traffic flow in the fabric is shown below.Figure 39 – L3 traffic flow – case both VMs are in the same ESXi hostFigure 40 – L3 traffic flow – case both VMs are in different ESXi hostsDistributed FirewallingGoal of the Distributed Firewalling labIn this step, you’ll create the Distributed Firewall rules.Figure 41 – Logical View Distributed FirewallCreate the Distributed Firewall rulesFor ease of use, the example below is using Logical Switch Names for the “Source” and “Destination” instead of subnets.This option works only if you have the VM Tools installed on the VMs.If you do not have the VM Tools on your VMs, use subnet.From NSX Home -> Firewall, create the rules:1)External

Modbus Over Serial Line Specification & Implementation Guide
The MODBUS standard defines an application layer messaging protocol, positioned at level 7 of the OSI model that provides "client/server" communications between devices connected on different types of buses or networks. It standardizes also a specific protocol on serial line to exchange MODBUS request between a master and one or several slaves. The objective of this document is to present the MODBUS protocol over serial line, in order to be used by all system designers when they want to implement MODBUS protocol on their serial line products. Thus, this document will facilitate interoperability between devices using the MODBUS protocol. This document comes in complement to the document called "MODBUS Application Protocol Specification". In chapter 5 different implementation classes are defined for "MODBUS Serial Line". requirements that a device must respect in order to belong to that class. Specification of a class is the sum of
