    Ye, the local will be able to function but the master is needed for the following :
    - push config
    - arm calculations
    - ids/ips

    Yes

    All the APs termintating on the local controller will keep working

    The thing is that you wont be able to modify ap configurations or any configuration that the master syncronize with the  local controller.

     

    Cheers

    Something else to keep in mind, is that the local-user/ap databases are master only, so if you're making use of these, the local might run in a reduced service state during failover (i.e. certain configurations wouldn't work fully). Examples are...

     

    1. If you're using machine-auth enforcement.

    2. Using the local databases for guest or RAP authentication.

     

    I did have it in my mind a new feature was mentioned regarding syncing local databases from masters to locals, but maybe I imagined/dreamt it?!?!

     

    Thanks.

    Yes iLocal will still works, but take note not to reboot the local controller when your Master fails.

    Masters are responsible for the following functions in the WLAN:

    1. Policy configuration
    2. AP white lists
    3. Wireless security coordination
    4. Valid AP list
    5. RF visualization
    6. Location
    7. Initial AP configuration
    8. Control plane security
    9. Authentication and roles


    Locals are responsible for the following functions in the WLAN

    1. AP, AM, and SM configuration, management, and software updates
    2. Device session termination
    3. ARM assignments and load balancing
    4. RFProtect™ security enforcement and blacklisting:
    5. RFProtect spectrum analysis
    6. CPsec AP certification
    7. Mobility
    8. Quality of service (QoS)
