b. 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.
c. Hide SSID: Select this check box if you do not want the SSID (network name) to be visible to users.
d. Inactivity timeout: Indicates the time in seconds after which an idle client ages out. The minimum value
is 60 seconds and the default value is 1000 seconds.
4. Click Next and set appropriate security levels using the slider button in the Security tab. Default selection is

Percentage of Airtime: Indicates the aggregate amount of airtime that all clients on this Network can
use to send/receive data.
Each user: Indicates the throughput for any single user on this Network. The throughput value is
specified in kbps.
Each radio: Indicates the aggregate amount of throughput each radio (some AP models have multiple
radios) is allowed to provide for all clients connected to that radio.
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 upto 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.
then,
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
Controller" on page 76 for configuring the DHCP server.
