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.

Working with SNMP Traps in Nectus NMS

One of the key features of Nectus is ability receive SNMP traps.  This allows the operator to quickly detect physical (links failures, flaps) or logical (adjacencies failures, flaps) changes in the network followed by restoration procedures or root cause analysis.
Let’s see how does it work on example of this Layer 2 diagram:

The SNMP traps are located in top menu “Logs” -> “SNMP traps and Syslog”.

More exactly here:

Once the devices starts sending SNMP traps, they appears withing 2-3 minutes in Nectus:

At the time of the writing, the new SNMP traps decoding is added manually by the Nectus support team, but in the future the operator will have the ability to add the traps decoding with no external assistance.
All these traps were sent by R1 and R2 when GigabitEthernet0/1 on R1 was shut down. Because OSPF was running between R1 and R2, disabling the interface lead to OSPF adjacency between the two routers to go down.
As you can see, some OIDs are represented their original format, whereas some OIDs are represented in a more human readable format.
The details of a trap might look like this:

With the above trap details, you can tell that this is “link down” trap.
However, with other traps, you might need additional knowledge to figure what they represent.
Let’s take another example of detailed trap:

This trap was sent by R1 and it is a neighbor state change(.1.3.6.1.2.1.14.16.2.2):

And it can be read like this: Router-ID 192.168.0.2(.1.3.6.1.2.1.14.1.1) declared neighbor 192.168.0.3(.1.3.6.1.2.1.14.10.1.3) with IP address on the interface 10.0.0.14(.1.3.6.1.2.1.14.10.1.1) as Down(.1.3.6.1.2.1.14.10.1.6 with value of 1).
Obviously this is not very intuitive and Nectus should do all the the decoding so that the operator will not go through all the effort to find what each OID means.

In the future releases user will have an option  to add the decoding for new or unknown SNMP traps via GUI.

Meltdown and Spectre bugs in simple words.

Meltdown and Spectre bugs in simple words.

All modern processors have very important feature called “Speculative Execution” where CPU tries to predict all possible operations that might be required to be executed next and actually executing those without knowing for sure which one will be the next.

Those guesses are called Speculative Branches. By the time when next operation is determined CPU already executed it as part of “Speculative Execution” but it also executed all other branches that no longer needed. Not only it executed unneeded operations it also kept the data for those branches. Data that was processed during unneeded Speculative Execution branches remains accessible for some time before it is completely discarded.

But data protection is only enforced for main execution branch, but not for Speculative Execution branches making it possible to access sensitive data that normally should not be accessible. Good intentions causes harm..

Will SDN kill CLI?

Trust me. CLI is not going anywhere. CLI is the only way to troubleshoot SDN.
There will be plenty of new CLI commands to “show” flow tables logic, operation
and debug communications between data plane and controller.

I would say importance of CLI is even greater in SDN as you now has
to observe operation between Control plane and Data plane which previously “just worked”.

CLI is here to stay, it just going to be used mostly for monitoring rather than configuration.

Monitoring of OpenFlow SDN networks

So.. you upgraded your network from legacy dedicated hardware to OpenFlow based SDN, laid off all of your network engineers who know CLI and ask yourself a question: How do I monitor my SDN now?

How do I pull a power supply status or CPU temperature? How to read TCAM utilization level? How to see an SFP status or number of CRC errors?

If we look into OpenFlow specifications, it defines communication protocol between OpenFlow controller (control plane) and OpenFlow switch (data plane) it goes into details of flow creation and management but there is nothing that tells how hardware monitoring has to be implemented on OpenFlow SDN switch.

Access to operational monitoring features that we love so much is not a part of OpenFlow specifications and will not be a part of SDN controller functionality. Old and proven SNMP-based monitoring is likely to continue to be a primary way to monitor your Data plane operation as it was with legacy dedicated hardware unless OpenFlow specs get expanded with new monitoring specifications.

Building Dynamic Interactive Network Diagrams

This post will cover how Nectus can dynamically build topologies and how you can check various performance statistics.
Nectus gives the possibility to build automatically L2 and L3 topologies based on the discovered devices.
Additionally, it allows the administrator to create custom topologies by dragging on the map the devices that are required to be on the topology. Read more

Configuration Backup and Change Tracking in Nectus

This post will cover the configuration backup and change tracking features available in Nectus.
Nectus provides the ability to back up the configuration of the devices discovered, on a scheduled basis and manually.
Nectus comes with some default settings regarding the configuration backup and for others administrator input is required.
This is the configuration backup settings menu:

Multiple tabs on the menu allows you to specify some parameters like what to be backed up and for how long to keep a configuration backup:

Or how often and when the automatic backup should happen:

The next two tabs are for telnet protocol configuration:

And ssh protocol configuration:

The remaining two tabs allows the administrator to use custom specific scripts for backup (in case you would like to perform partial backup for instance).
Nectus must connect to the device using a valid username/password combination on that device.
If the username/password exist on the device, then it must be fed to Nectus.
This is where you set this up:

And these are the input values required

Once this is done, you can backup configuration per device, per group of devices (vendor, platform, model) or for all devices.
This is how you can backup a group of devices, which in this case is the same as all the devices are backed up (this is because there are only Cisco devices in the topology):

From the inventory menu, you can see the successful backups and the failed backups.
If the backup failed, then you would see like this:

You can see the reason it failed, which in this is because Nectus could not establish a telnet or SSH connection to the device:

If the backup is successful, the device configuration should show up:

Clicking on any of the files, you will see the configuration of the device at the time configuration backup was triggered:

Each device context menu has a configuration backup section where you can perform various actions:

You can backup the configuration, view the running configuration:

Or you can view the archive of all the device backups:

Further on, you can compare two backup files to see what has changed.
They do not need to be consecutive backups. Here, “auto-cost reference-bandwidth” was configured on the device:

Another useful feature is the tracking change feature which shows the changes between two consecutive backups.
You select the newer backup and Nectus will show what has changed since the previous backup was taken:

In case there are backups that were taken before Nectus was deployed and you would like to see what are the changes between those configurations and the ones taken by Nectus,
you have the possibility to compare the Nectus backups with the external files. You can even compare two external configuration backups with the help of Nectus.
Another useful feature that is related to configuration backup, is the report that tracks the devices whose configuration was not saved after the last change.

You can trigger this report like this:

You can specify if you want to send the report to an email address and if you also want to keep this report for auditing purposes:

And the report looks like this:

Keep in mind that the time you see in the report is the uptime of the router. For instance, in the above example,
the device configuration was saved last time when the router had an uptime of 1h47m
and the last configuration change was done when the router had an uptime of 1h50m.
And this would pretty much all about configuration backup and change tracking in Nectus and how it can help you to save your configurations and see
what has changes from one backup to the next one or any other backup.
