Preventing Clients from Accessing the Management Network on a Controller
To prevent or block a wired or wireless client from accessing the management network on a controller
(from the wireless client dynamic interface or VLAN), the network administrator should ensure that

Cisco recommends that load balancing always be turned off in any wireless network that is supporting
voice, regardless of vendor. When load balancing is turned on, voice clients can hear an audible artifact
when roaming, and the handset is refused at its first reassociation attempt.
