AeroHive – access to MyHive landing page

The AeroHive user, which is created by default, gets a landing page, when logging into https://myhive.aerohive.com. The user can choose between the HiveManager Online and the Redirector.

When the users chooses the HiveManager Online or the Redirector, the user has the option to return to landing page by choosing the MyHive option in the upper right corner.

Subsequent users don’t get the landing page by default and don’t have the option to choose the MyHive option. Subsequent users (even if the belong to the group Configuration and Monitoring) don’t have the permissions to access the Redirector.

The default user has the option to provide access to the landing page. This configuration is done per user and can only be done by the default user. Just edit the user and enable the option “Give user access to MyHive landing page”.

When the users logs in to his HiveManager page, he will get the landing page to choose between the HiveManager Online and the Redirector.

Cisco WLC – Upgrade FUS image

Today I upgraded a FUS image on a Cisco WLC 5500 controller, because I also upgrade the WLC software to 7.2.103.0. The FUS upgrade is straightforward and comparable to a regular software update. The only difference is that you need console access to perform the upgrade. The FUS image upgrades the following components:

• Field Recovery Image is upgraded to runtime image version
• Bootloader is upgraded to 1.0.16
• Offline Field Diagnostics is upgraded to 0.9.28
• FPGA Revision version is upgraded to 1.7
• Environment Controller (MCU) Image version is upgraded to 1.8
• USB Console Revision version is upgraded to 2.2

During the upgrade process you have to confirm to proceed the upgrade, like shown below

Checking for Field recovery image upgrade

This happens multiple times and the controller reboots several times during the upgrade. It took about 20 minutes for the complete upgrade of the FUS image.

AeroHive Spectrum Analysis

One cool feature about AeroHive is the build-in Spectrum Analysis feature, which is enabled by default from HiveOS 4 and higher. Spectrum analysis is very useful to get a view of the RF environment near an access-point.  This is especially useful when troubleshooting bad connections (high volume of retransmissions) or other problems related to the RF environment. A spectrum analysis can help to detect interfering components, like bluetooth devices, cellular phones or a micro wave.

HiveAPs even have the possibility to recognize device types, which interfere with the wireless environment. Device identification is only possible with HiveAP 110, 120 and 170 access-points. The HiveAP 320 and 340 cannot perform any kind of spectrum analysis and the HiveAP 330 and 350 can perform a spectrum analysis, but don’t have the device identification feature.

To perform a spectrum analysis with AeroHive, you need to configure at least one SSID. When the SSID is configured you have the option to perform the analysis in both the 2.4 Ghz and the 5 Ghz band.

To start the analysis, open the HiveManager, click Monitor – Access Points – HiveAPs and select a HiveAP, then click Tools – Spectrum Analysis to begin the spectrum analysis. The screenshot below shows the spectrum analysis pane.

A full description of the different panes can be found in the online HiveManager WebHelp. I like the spectrum analysis feature, because of it’s power and strength during troubleshooting and planning of a wireless environment.
