Important Notes
Re-enable Broadcast after Upgrading to Release 4.0.206 or Later
In software releases 4.0.179 and earlier, broadcast and multicast forwarding were both controlled with
a single global flag that enabled multicast. In software release 4.0.206 these functions were broken into
separate configuration flags: one that contols broadcast and one that controls non-broadcast multicast.
If you have multicast enabled in software releases 4.0.179 and earlier, the broadcast flag is left disabled
after upgrading to software release 4.0.206. As a result, some applications that rely on broadcast do not
work after the upgrade.

After you upgrade to software release 4.0.206.0 or later, use this CLI command to re-enable broadcast:
config network broadcast enable
When re-enabled, broadcast uses the multicast mode configured on the controller. If you want to turn on
broadcast only and set it to another multicast mode you must use the CLI because the GUI configuration
forces multicast on.

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
there is no route through which to reach the controller from the dynamic interface or use a firewall
between the client dynamic interface and the management network.
