Introduction

This document provides examples for using WSM dashboard to monitor wireless services.

WSM provides wireless service data in the dashboard in real time to provide support for network analysis and operation decisions.

Prerequisites

Before you use the dashboard to monitor wireless services, complete the following tasks:

·     Create a WLAN to be monitored. Make sure the routes are reachable.

·     Add wireless devices to WSM.

Example: Using WSM dashboard to monitor wireless services

Network configuration

As shown in Figure 1, use WSM dashboard to monitor wireless services in an office building.

Figure 1 Network diagram

 

Analysis

To use WSM dashboard to monitor wireless services, complete the following tasks:

1.     Configure a dashboard view to add widgets.

2.     Open the dashboard to monitor wireless services in real time.

3.     Analyze the wireless services based on the monitoring result.

Software versions used

This configuration example was created and verified on the following software versions:

·     IMC PLAT 7.3 (E0504P04).

·     IMC WSM 7.3 (E0505).

Procedures

Adding a dashboard view

1.     Log in to IMC.

2.     Click the  icon at the top right of the IMC home page.

3.     From the navigation tree, select Dashboard > Configuration, as shown in Figure 2.

Figure 2 Dashboard

 

The dashboard configuration window appears, as shown in Figure 3.

Figure 3 Dashboard configuration window

 

4.     Click the  icon in the Grid Properties area.

The Add View window appears, as shown in Figure 4.

Figure 4 Add View window

 

5.     Enter WLAN in the View Name field.

6.     Click OK.

 

	NOTE: An operator can add a maximum of 10 dashboard views.

 

Setting dashboard view parameters

·     In the Grid Properties area, set the following parameters as needed, as shown in Figure 5:

¡     Enter Wireless Service Monitor in the Title field.

¡     Use the default value 45 for the Title Size field.

¡     Use the default color for the Title Color field.

¡     The values of the Screen Width (PT) and Screen Height (PT) fields are automatically populated based on the computer resolution. In this example, the values are 1440 and 900, respectively. You can modify the values. The system automatically modifies the number of grids after you modify the values.

¡     Enter 3 in the Scroll Region Height field, which indicates that the height of the scroll region is the sum of the heights of three grids.

¡     Enter 4 in the Scroll Number field, which indicates that four widgets are deployed in the scroll region.

¡     Enter 4 in the Scroll Unit Column field, which indicates that the column of each widget occupies four grids.

¡     Use the default value 10 for the Scroll Interval(Second) field.

¡     Set the displaying order for the view in the Sortable view index field. If multiple views exist, the views will be displayed in the specified order.

·     In the Global Settings area, you can select Switch Views to enable automatic view switching at the specified interval.

·     In the View Management area, you can click the switching icons  or  to configure different views. The switching action does not automatically save the current view configuration. In this example, one view is configured.

You can use the scroll wheel to switch between different views when you display dashboard views.

Adding wireless service widgets

1.     In the Global Settings area, select Wireless LAN from the System Widgets list as shown in Figure 5. The Widget area will display only wireless service widgets.

2.     In the Widget area, drag and drop widgets to the Scroll area and Panel area as needed, as shown in Figure 6:

a.     Add the following widgets to the Scroll area:

-     Wireless Alarm

-     Client Count

-     Rogue AP and Rogue Client

-     Fit AP Model

b.     Add the following widgets to the Panel area:

-     Wireless Topology

-     Resource Statistics

-     Reasons for Association Failures - Today

-     AP Bandwidth

3.     Right-click a widget, and then select Preview from the shortcut menu to preview the monitor, as shown in Figure 7.

You can modify the number of grids occupied by the widgets or the location of the widgets based on the preview result in the panel area.

Setting widget parameters

You need to set widget parameters for some widgets. In this example, set widget parameters for the Wireless Topology widget.

To set widget parameters:

1.     Right-click the Wireless Topology widget, and then select Configure Parameters from the shortcut menu.

The Add Location page appears.

2.     Set the following parameters, as shown in Figure 8:

a.     Select Floor from the Location Type list.

b.     Select Canteen B1 from the Location Name list.

Figure 8 Add Location

 

3.     Click OK.

The canteen B1 wireless topology is displayed, as shown in Figure 9.

4.     Click the Save icon .

Viewing the monitoring result

1.     Point to the  icon, and then select Dashboard > WLAN from the shortcut menu.

The Wireless Service Monitor page appears, as shown in Figure 10.

2.     Right-click the Wireless Service Monitor page.

The Change Theme window appears, as shown in Figure 11.

Figure 11 Change Theme window

 

3.     Select a theme name.

Table 1 provides widgets and the wireless service each widget indicates.

Table 1 Wireless widgets

Widget	Description
	Displays information about alarm levels in bar charts.
	Displays the number of rogue APs and rogue clients detected by H3C fat APs and fit APs in bar charts.
	Displays the model name and proportion of fit APs in the WLAN in a pie chart.
	Displays the number of online clients in a time range.
	Displays the specified location view topology.
	Displays the trends of the send and receive rates of APs in a time range.
	Displays the number of alarms at each level for ACs, fit APs, and fat APs on the WLAN. The alarm information automatically changes every 5 seconds in the order of AC, fit AP, and fat AP.
	Displays the proportion of reasons for client association failures from 00:00 to the current time in bar charts.

 

Analyzing the WLAN

You can analyze the running status of the WLAN based on the monitoring result.

For example, the Resource Statistics widget shows that a critical alarm occurs for a fit AP, as shown in Figure 12. Then you can use the wireless topology to locate this fit AP, as shown in Figure 13.

Figure 12 Resource statistics

 

Figure 13 Wireless topology

 

As shown in Figure 14, if a large number of rogue APs and rogue clients exist on the WLAN, you need to check for attacks on the WLAN and locate the problem to ensure WLAN security.
