Virtual WLC High availability (HA)

[Hacen.bani]

hello,

i will configure two Virtual WLC on ha 

i will need one or two licenses for each controllers ?

what's the type of license needed

thanks 

[Sandeep Choudhary]

you will need license on both vWLC. It will be normal AP license.

HA AP SSO isn't supported on the vWLC.  You can have two vWLC doing redundancy with high availability configured on the AP.

you need to change manually on both WLCs. Config will not sync....
