b. Broadcast/Multicast
 Multicast optimization— When Enabled, the IAP will choose the optimal rate for sending broadcast
and multicast frames based on the lowest of unicast rates across all associated clients. The default
values are 1 mbps for 2.4GHz and 6 mbps for 5.0GHz bands. Multicast traffic can be sent at up to 24
mbps when this option is enabled. This option is disabled by default.
 Broadcast filtering— When set to All, the IAP will drop all broadcast and multicast frames except for
DHCP and ARP. When set to ARP, in addition to the above, the IAP will convert ARP requests to
unicast and send frames directly to the associated client. When Disabled, all broadcast and multicast
traffic is forwarded.
 DTIM interval— Indicates the DTIM (delivery traffic indication message) period in number of
beacons. You can configure this option for every WLAN SSID profile. The default value is 1, which
means the client will check for buffered data on the IAP at every beacon. You may choose to configure
a larger DTIM value for power saving.
c. Transmit Rates— Indicates the ability to configure the basic and supported rates per SSID for Dell
Instant. Select to set the minimum and maximum legacy (non-802.11n) transmit rates for each band -
2.4GHz and 5GHz.

Table 9 Conditions for Client IP and VLAN assignment
If then
You select Virtual Controller assigned The client gets the IP address from the Virtual Controller. The Virtual Controller
creates a private subnet and VLAN on the IAP for the wireless clients.
The Virtual Controller NATs all traffic that passes out of this interface. This
setup eliminates the need for complex VLAN and IP address management for a
multi site wireless network. See Chapter 7, “Virtual Controller” on page 91 for
configuring the DHCP server.
You select Network assigned By default, the client VLAN is assigned to the native VLAN on the wired
network.
 Default— The client gets the IP address in the same subnet as the IAPs.
 Static— Select to specify a VLAN for all clients on this network.
 Dynamic— Select to create rules for per-user VLAN assignment. See
“VLAN Derivation Rule” on page 124 for more information.
