LiveNX 5.2 Quick Start Guide
The purpose for this Quick Start Guide is to provide quick and detailed instructions setting up LiveAction for the first time. In addition, the guide will navigate through LiveNX’s user interface and configuration of LiveNX’s Server, Client and Platform.
1-1| LiveNX 5.2 Quick Start Guide
1. Deployment Options
Single Server
Single server deployment of LiveAction consists of installing the server on a 64-bit Linux or Windows Server or VM. Since the LiveAction server has a built in collection node, it is fully useable without any additional installations.
Distributed Deployment
In distributed deployments, a single server is deployed as usual but additional collection nodes can be deployed and associated to the single server.
Virtual Machine
Servers and nodes can be deployed on VM as long as the performance requirements for compute, store and network are met.
Deployment Decision
The use and location of additional nodes are based on 3 criteria
Performance o Off load performance to another node.
Location o Place node near devices being polled. o Place at a branch site so data is not polled across the WAN to the DC where the server exists.
Security o Place node for different security zone, DMZ. o Node will initiate communication from security zone to server o In case of loss of communication, server of node may initiate communicates to reestablish

Note: Forgetting the passwords for all administrative accounts will require resetting all LiveAction settings and rebuilding your configuration. Refer to the LiveAction User Guide Chapter 3.12 Lost Passwords for more information on recovery.
Add Devices to your Topology
To discover devices: File > Discover Devices.
The image below shows how to specify how LiveAction will discover your devices. Scan by a range of IP addressed from lowest to highest separated by a hyphen (no CIDR notation) or include a list of individual IP addresses (per line). There are options to specify the IP of the seed device to scan. Then specify the connected devices to be included by indicating the number of hops those devices are from the seed device. Click OK. LiveAction will begin searching the network based on the list specified and show results.
5-17| LiveNX 5.2 Quick Start Guide
In the Device Discovery windows, select the Devices that were discovered > Click Add Devices to add them to LiveAction. Select or deselect all devices by right clicking inside the Select column.
5-18| LiveNX 5.2 Quick Start Guide
Enable/Configure Cisco Devices for QoS, Flow and IP SLA
After any supported Cisco devices are added to the topology they need to be configured for advanced monitoring and control of technologies such as QoS, NetFlow, IP SLA and NBAR. The Device Discovery wizard will prompt to configure the devices that were just added. Click Yes to configure them with the device setup wizard. Please refer to Basic Setup and Operations, Chapter 4.2 of LiveAction User Guide for step-by-step instructions on how to Configure Cisco Devices for QoS, Flow and IP SLA.
Set up Your LiveAction User Accounts
The administrator account has full access to device configuration and monitoring, as well as user management. For day-to-day use of LiveAction it’s recommended to create and use accounts with Full Config or Partial Config roles.
Go to Users > User Management to create user accounts with the appropriate roles. See LiveAction User Guide, Chapter 3 Role-Based Access for information on creating user accounts.
If the administrator account password has been lost, a reset and rebuild of the configuration of LiveAction will be required. Refer to Chapter 3.12 of the user guide for information on Lost Passwords.

7. Appendix D: NetFlow Deployment Considerations
NetFlow data is sent by network infrastructure devices (routers/switches/etc.) across the network to LiveAction collector Nodes. This important technology does consume a minimal amount of network bandwidth in order to deliver the management data it provides. The purpose of this document is provide examples of NetFlow bandwidth consumption rates from real networks that LiveAction is managing to assist network architects with data points for capacity planning.
LiveAction can be used to track both the Flow rate per second and the actual bandwidth consumption of NetFlow by using its own NetFlow Reports.
The volume of NetFlow data that is placed on the wire by a devices is proportional to two main factors.
Number of interfaces enabled for NetFlow
Volume of end user data (voice/video/web/etc.) on the network.
LiveAction recommends enabling Flow on the fewest interfaces possible that still provides the fullest view of network traffic. Most Cisco devices support NetFlow being configured bi-directionally on an interface – in both the input and output directions. If Flow is configured by-directionally on two interfaces, for example, on the LAN and WAN interface of a WAN router, then two Flow records will be created and sent to LiveAction for each minute that a conversation is active. One record will be created as the conversation enters the LAN interface and a second record will be created as the conversation leaves the WAN interface. This means that Flow will consume twice the bandwidth required to report on that one event. To limit the bandwidth utilization of NetFlow, LiveAction recommends enabling Flow bi-directionally on only the WAN interface(s) of WAN devices.
Some Cisco devices only support Flow configured in the input direction. For these devices, the same principles apply, configured Flow on the fewest number of interfaces that still provide the fullest view of the network traffic.
The second main factor for determining the volume of bandwidth consumed by NetFlow is bandwidth usage is proportional to the volume of user data that is traversing the network. For example, NetFlow has the capability to consume less bandwidth on a low T1/E1 WAN links than a 100Mb WAN link. But if there is only a T1/E1s volume of end user data on a 100Mb link, its NetFlow consumption would similar to that of a physical T1/E1.
Example Flow Bandwidths
The following table contains data taken from LiveAction running in production networks. The values represent sample utilizations from actual WAN environments.
Each of these examples has Flow configured bi-directionally on only the WAN interface.

Core WAN Router
22,000 ~4-4.2Gbps 11Mbps (.02%) 12Mbps (.02%)
Note: the percentages represent the percent of bandwidth utilized by Flow compared to rest of the end-user bandwidth
Example Node/Server Bandwidth
LiveAction can be deployed in distributed architecture. When using this model, LiveAction Node collectors will receive NetFlow and SNMP data from infrastructure devices (routers/switches/etc.) and store it locally. The LiveAction Server will request specific data from the Nodes on demand to render end-user views, dashboards and reports. There is also minimal synchronization communication between the Server and Node(s). The volume of bandwidth used by the LiveAction Server and Node(s) is proportional to the number of devices being monitored by each Node and the number of end-user actively monitoring LiveAction.

The following table provides example bandwidths of this communication.
Devices Per

100 125Kbps/1.2Mbps 5Kbps-25Kbps
500 625Kbps/ 1.75Mbps 25Kbps-125Kbps
1000 1.25Mbps/ 2.25Mbps 50Kbps/ 250Kbps
Note: These are typical bandwidth estimates that LiveAction would expect to see. Each network is different so results may vary.
