Virtual Wireless Controller (vWLC) Installation, Configuration, License Activation - 7.3 Release

Rising star

Madhushree Saroja is a Testing Engineer in Wireless Engineering Team. In this Video Series Madhu explains about the Virtual Wireless Controller (vWLC) Installation, Configuration and License Activation.

Until 7.3 releases, all Wireless LAN controllers (WLC) ran on a dedicated hardware. For example we have 5500 Series, 2100 Series,

2000 series WiSM on CAT6500 etc.

The virtual wireless LAN controller (vWLC) is software that can run on hardware that is compliant with an industry standard virtualization infrastructure.

Virtual wireless LAN controllers provide flexibility for users to select the hardware based on their requirement i.e. VMWare,ESX and ESXi 4.x & 5.x version. The Virtual Controllers are NOT expected to replace shipping hardware controllers.

Very informative but voice clarity could have been better, sounded like she was speaking away from the microphone.


is there any way to clear up the audio



I have a question about the licensing of the vWLC used as fallback (secondary controller) next to an primary 5760 WLC. Is this possible at all? and if yes, what type of licensing do i need for the vWLC?

Do i need an AP count licence for all AP's on the fysical and also the vWLC or only for one of them? for what i know there is no HA licence for the vWLC.

Please help me!!

kind regards.
