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. 4. Click Next to continue. 5. Select the required Client IP assignment option - Virtual Controller assigned and Network assigned. Table 9 Conditions for Client IP and VLAN assignment If then You select Virtual Controller assigned You select Network 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. 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. 6. Click Next to continue. Dell PowerConnect W-Series Instant Access Point 6.1.3.1-3.0.0.0 | User Guide Wireless Network | 61

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.
4.
Click
Next

5.
Select the required Client IP assignment option — Virtual Controller assigned and Network assigned.
6.
Click

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.
