Nectus Wireless Features

Tracking Objects in Wireless Networks

, ,

Troubleshooting of any wireless problems usually starts with determination of specific Access Point where client is currently associated with and tracking wireless client’s roaming behavior in time.

Access Point detection helps to understand current RSSI levels at given selected channel and presence of alternative AP at the client’s location.

Nectus provides basic tools that make locating and tracking wireless objects an easy task.

The specific topics we will cover in this chapter are:

  1. Using the Wireless Client Search Tool
  2. Using the Wireless Client Tracking Tool

1. Using the Wireless Client Search Tool

The Wireless Client Search tool shows you which access point (AP) a Wireless Client is connected to right now. To use Wireless Client Search go to the Nectus Home Screen and select Tools -> Wireless Tools -> Wireless Client Search.

This opens the “Wireless Client Search” dialog box.

Search for the wireless object by entering all or part of the Client MAC Address, IP Address, or Username. Set the Search Scope by checking any of the supported Wireless Controller types.

The search returns any matching objects in a table.

Click the MAC Address of the object to see all the Basic information the system has about that object.

Click the Client RSSI Info tab to see the RSSI (Received Signal Strength Indication) for every access point the object can detect.

2. Using the Wireless MAC Tracking Tool

The Wireless MAC Tracking tool is useful for troubleshooting intermittent problems. It uses the object’s MAC address to record which AP the object is connected to over a period of time. To use Wireless Client Search go to the Nectus Home Screen and select Tools -> Wireless Tools -> Wireless MAC Tracking.

This opens the “Wireless MAC Tracking” dialog box.

Click Add to begin tracking a MAC Address.

Enter the MAC Address you want to track, the Controller type, the Frequency of recording data, and the Duration of time you want to track the MAC address.

Once the Duration is complete, you can see the results by clicking the View MAC Tracking icon.


Generating Wireless Heat Maps in Nectus

Generating Wireless Heat Maps

Wireless Heat Map is the visual representation of the wireless signal levels at different locations of specific selected area.

Area can be a building floor or outdoors. We read signal level directly at the antennas of the Wireless APs and calculate signal attenuation with a distance

and overlay resulting signal levels on top of area map with a known dimensions.

In this chapter, you’ll learn how to generate Wireless Heat Maps of any area.

The specific topics we will cover in this chapter are:

  1. Preparing the Background Image
  2. Creating a New L2 Topology
  3. Placing the Background Image and Specifying the Scale
  4. Selecting the Wireless Controller
  5. Expanding the Topology and Selecting Your Access Points
  6. Positioning Wireless APs on the Heat Map

1. Preparing the Background Image

The Background Image shows the physical layout of the area that will be included in the Heat Map.

The image needs to be scaled with equal proportions horizontally and vertically. PNG and JPEG image formats are supported. You will need to be able to enter the corresponding length of the image, in feet, to create an accurate Heat Map.

Create the Background Image before proceeding to Step 2.

2. Creating a New L2 Topology

Once you have the Background Image prepared, you will need to create a new L2 Topology for your Heat Map. To create a new L2 Topology go to the Nectus Home Screen and select Topologies -> Start New L2 Topology.

An empty L2 Topology appears.

3. Placing the Background Image and Specifying the Scale

To place the Background Image in the Topology, click the L2 Topology Settings icon to open the “Settings” dialog box then select the Background tab.

Check the Display Image check box and load the Background Image you created in Step 1.

Enter the horizontal length of the Background Image (in feet) in the Background image length in Feet field.

Once the Background Image is visible in the Topology you can resize and reposition it as desired.

4. Placing the Wireless Controller

Find the Wireless Controller for this area in the Wireless Controllers section of the Sites Panel and drag it onto the Topology.

Click the Settings icon to open the “Settings” dialog box. Select the Wireless tab.

Check Show Wireless APs along with any other options you want displayed on the Heat Map. Nectus includes a large collection of Wireless AP icons you can use to customize the map.

Once you click OK the Heat Map reappears with a color-coded scale of signal levels.

5. Expanding the Topology and Selecting Your Access Points

Now you need to expand the Topology. This displays the Wireless Access Points that are connected to the Wireless Controller. To expand the Topology, right-click the Wireless Controller icon and select Expand L2 Network Topology.

This opens the “Expand L2 Network Topology” dialog box. Select the Wireless tab and expand the All Wireless Controllers list to see the Wireless APs connected to the controllers in the Topology. Check the Wireless APs you want to include in the Heat Map.

Click Generate Topology to add the selected Wireless APs to the Heat Map.

6. Positioning Wireless APs on the Heat Map

Drag each Wireless AP to its physical location on the Background Image. Once you do this, the Heat Map will show wireless coverage for this area.

Aruba Wireless Dashboard added to Nectus 1.2.30

, ,

Support for monitoring Aruba wireless controllers was added to most recent release of Nectus NMS.  It brings visibility to most loaded wireless APs, SSIDs and controllers.

It displays basic antenna info, current AP channels, gives list of rogue APs and rogue clients and allows generation of Wireless HeatMaps over floorplans.



Cisco Wireless Dashboards

, , ,

After support for wireless devices was added in Nectus, specific monitoring dashboards were created to track any change that can affect the wireless users, controllers or access points.
The wireless dashboards are vendor specific and this is where you can find the dashboard for Cisco wireless devices:

The focus of this article is on Cisco wireless devices, this is how the Cisco wireless dashboard looks like:

Wireless dashboard has multiple sections.
One of the sections covers the controllers and can provide information about the CPU usage, how many APs are Up, Down or Downloading:

As always, you can get device details by selecting the controller:

The interesting things starts when you select the counters related to the number of APs that are up, down or in process of being associated with the controller.
You get a list of APs in that state associated with that specific controller:

To get details about an AP, it is enough to select one of the APs and a window with multiple tabs will provide various information that can help the operator to understand how that specific AP operates.
The first tab provides the name of AP assigned by the operator, the model of AP, the operating system, the IP address and some other useful information about the AP.

The next tab provides technical information about the two frequencies in which the AP operates:

In the next tab, quality of service settings are covered:

The forth tab is about the load in terms of number of clients, receive and transmit utilization for the frequencies supported:

The next tab shows the rogue APs detected:

You can also see the neighbor APs and some of their characteristics:

And the last tab shows the CDP neighbor:

Another section of the wireless dashboard is the SSID Client load which shows how many clients are on each SSID:

The wireless dashboard allows to see how many clients and on which frequency each AP has:

And the last section of the wireless dashboard is the one showing how many clients are on the two frequencies, 2.4Ghz and 5Ghz, in total and you can see some history of how many clients were at some point in time.

Nectus Cisco Wireless dashboard can provide useful information about the wireless devices, controllers and access points.

Cisco Wireless client search and tracking tools

, ,

In this post we will cover some new functionality added to Nectus in latest Wireless release.

The “Wireless Client Search” allows the operator to find any wireless client by its MAC, IP address or Username.

The client search is located under main menu “Tools”:

In the menu, you have an option to search for a client based on the MAC, IP or Username. You can also restrict the scope where the search will take place:

Here is how a result of a MAC search looks like. You can search using part of a MAC address as well, but you need to provide at least 3 characters (two numbers and “:” )

You can view the client details by clicking either on MAC address or IP address and the new window will show Client’s basic info like like SSID, RSSI etc.:

The second tab will show the RSSI from various APs that detects client’s signal:

If AP name is clicked, then you will get detailed information about the AP:

Next, you can search for an IP address (again, you do not have to specify full IP address):

The last option is to search using an username:

The username is shown in the client detailed information:

Coming back to the search window, there is the possibility to track a client. You actually track the MAC address of the client to see if and where the client roamed across the wireless network. One or more clients can be tracked in the same time:

You need to specify how often Nectus should check this MAC address and for how long. If you know the client goes on and off often or it moves around the wireless network, then you might want to use an aggressive timer for frequency to get accurate data about availability:

The list of the tracked clients can be seen here:

And the list is this:

A client can be added for tracking from this menu as well:

And here is how the tracking information looks like for a client:

This shows that the client did not move to another AP, so there was no or little movement of the client.


Cisco Wireless Heat Maps

, ,

In this post, we will cover the wireless heat maps and how they are created in Nectus.

A heat map will allow to visualize the state of the wireless coverage and help to take decision in order to improve the coverage.

Using the information from APs along with a map of physical location, you can find out where are the hot and cold spots.

A heat map is a L2 topology diagram where you can add access points and optionally the controller to which the access points are associated with.

You can add the controller and the APs from the list of controllers:

If the controller and several APs are added to the topology, it will look like this:

In the topology toolbar settings option, you must check the option to see access points in the topology:

Afterwards, the topology looks like this:

You can see which channel is used on each AP and how many clients are connected to each AP.
