Configuring NAM -WAAS Integration


This chapter describes how to enable WAAS to send flow information to the NAM VB and how to generate before-and-after reports to demonstrate the impact of WAAS.

This chapter contains the following:

Configuring WAAS to Send Flow Information to NAM VB

Before you can monitor WAAS traffic, you must first configure the WAAS device to export WAAS flow record data to the NAM VB.

Using the CLI

Use the following WAAS CLI flow monitor commands as follows:

config t

no flow monitor tcpstat-v1 enable

flow monitor tcpstat-v1 host <NAM-IP-ADDRESS>

flow monitor tcpstat-v1 enable

end

Using the WAAS Central Manager GUI

Click Configure -> Network Monitoring -> Flow Monitor and enter the NAM-IP-ADDRESS, then click Enable to enable Flow Monitoring shown in Figure 4-1.

Figure 4-1 Flow Monitor Settings

After you enable flow export to the NAM using WAAS CLI commands like those above, WAAS devices will be detected and automatically added to the NAM's WAAS device list. These commands can be configured on the Branch side WAE for client side response time analysis.

Configuring WAAS Data Source in NAM

Follow these instructions to configure WAAS Data Sources in the NAM VB.


Step 1 Login to the NAM VB GUI.

Step 2 Click Setup > Data Sources.

Step 3 From the contents menu, choose WAAS -- Devices.

Step 4 Choose the WAAS device you want to modify, then click Config.

Step 5 You can configure the WAAS data sources to monitor the following WAAS segments known as the WAAS Data Sources (Data Collection Points):

Client—This setting configures the WAE device to export the original (LAN side) TCP flows originated from its clients to the NAM VB to monitor.

Client WAN— This setting configures the WAE device to export the optimized (WAN side) TCP flows originated from its clients to the NAM VB to monitor.

Server WAN—This setting configures the WAE device to export the optimized (WAN side) TCP flows from its servers to the NAM VB to monitor.

Server—This setting configures the WAE device to export the original (LAN side) TCP flows from its servers to the NAM to monitor.

Passthru—This setting configures the WAE device to export passthru (non-optimized) TCP flows from its servers/clients to the NAM to monitor.

TCP flows from the Branch WAE can be exported to the NAM VB for before-and-after analysis. The following Data Sources can be enabled for each WAE or Branch side WAAS Data Source as shown in Figure 4-2:

Client

Passthru

Figure 4-2 WAAS Devices

You can also set up Data Sources from the Core-WAE. You can add the Server, Server-WAN and Passthru data sources to provide insights into the application performance analytics as observed from the server LAN, WAN, and the client LAN.

Step 6 Click Setup > Monitor and ensure that Core Monitoring and Response Time Monitoring are enabled for the WAAS Data Sources.


Note The Status will remain Pending, until the Monitored Servers are configured and the NAM starts receiving the flows from the WAE.



Configuring WAAS Monitored Servers in NAM VB

WAAS needs to know which flows it must export to the NAM VB. By entering a Server IP addresses in the WAAS Monitored Servers, you enable the WAAS to export flows related to those servers to the NAM VB. This enables the NAM VB to monitor the response time for the given servers.

Step 4 (Netflow) can be used to help identify business critical applications and the servers that hold them.


Step 1 Login to the NAM VB GUI.

Step 2 Click Setup > Data Sources.

Step 3 From the contents menu, choose WAAS > Monitored Servers.

Step 4 Click Add and enter the test server IP address in the Server Address field.

Step 5 Figure 4-3 shows an example of the WAAS Monitored Servers window.

Configuring Response Time Reports for Impact Analysis

The Cisco NAM VB reports function enables you to store and retrieve up to 100 days of historical data about the network traffic monitored by the NAM VB. Response Time reports in NAM can provide visibility into the impact of WAAS optimization.

You can use the NAM VB to create a response time report for the average transaction time as experienced by the client, based on the Client Data Source and the Passthru Data Source on the Branch WAE. This report will provide visibility into response time improvement experienced by the branch.


Step 1 Log in to the NAM VB GUI.

Step 2 Click Reports > Basic Reports.

Step 3 Click Create, then choose Response Time from the list of report types.

Step 4 Enter the Application information for the application and the server.

Step 5 Select Data Type as Avg. Transaction and Data Source as WAE-<BranchWAE-IP>-Client.

Step 6 Click Create, then choose Response Time from the list of report types.

Step 7 Enter the Application information for the application and the server.

Step 8 Select Data Type as Avg. Transaction and Data Source as WAE-<BranchWAE-IP>-Passthru.

Step 9 Click Create, then choose Response Time from the list of report types.

Step 10 Enter the Application information for the application and the server.

Step 11 Select Data Type as Avg. App Delay and Data Source as WAE-<BranchWAE-IP>-Client.

Step 12 Click Create, then choose Response Time from the list of report types.

Step 13 Enter the Application information for the application and the server.

Step 14 Select Data Type as Avg. App Delay and Data Source as WAE-<BranchWAE-IP>-Passthru.

Step 15 Click Reports > Basic Reports.

Click to choose multiple reports, then click View to generate a composite report.


Configuring Host Throughput Reports for Impact Analysis

The host throughput report can show the reduction in the bandwidth utilized by the host traffic after optimization.


Step 1 Log in to the NAM VB GUI.

Step 2 Click Reports > Basic Reports.

Step 3 Click Create, then choose Hosts from the list of report types.

Step 4 Enter the Hostname, IP address, and any required Application information.

Step 5 Set the Data Source as WAE-<BranchWAE-IP>-Client.

Step 6 Click Reports > Basic Reports.

Step 7 Click Create, then choose Hosts from the list of report types.

Step 8 Enter the Hostname, IP address, and any required Application information.

Step 9 Set the Data Source as WAE-<BranchWAE-IP>-Passthru.

Step 10 Click Reports > Basic Reports.

Click to choose multiple reports, then click View to generate a composite report.
