Thanks for you reply Michael and sorry for not being clear.
I am trying to configure the ZD1000 in order to have the attribute Nas-Identifier set to MAC addess of the Controller. By default, this attribute is set with the WLAN BSSID which is the MAC address of the AP (this is what I currently have/get).
According to the 'Ruckus Wireless ZoneDirector Command Line Interface - Reference Guide' (p. 265), I should be able to change this setup by using this command:
nasid-type nas-addr
But it does not work.
My ZD's firmware is v9.3, do you think upgrading it to a more recent version will fix my problem?
Thanks again for your help.
