MSM7xx Controllers Configuration Guide v6.4.0

WLAN
Settings
Name (SSID)
Specify a name to uniquely identify the wireless network associated with this VSC. The wireless
network is created by the controlled APs and managed by the controller.
Each wireless user that wants to connect to this VSC must use the WLAN name. The name is
case-sensitive.
DTIM count
Specify the DTIM period in the wireless beacon sent by the controlled APs. Client stations use
the DTIM to wake up from low-power mode to receive multicast traffic.
APs transmit a beacon every 100 ms. The DTIM counts down with each beacon that is sent.
Therefore if the DTIM is set to 5, then client stations in low-power mode will wake up every
500 ms (.5 second) to receive multicast traffic.
Broadcast name (SSID)
When this option is enabled, APs will broadcast the wireless network name (SSID) to all client
stations. Most wireless adapter cards have a setting that enables them to automatically discover
APs that broadcast their names and connect to the one with the strongest signal.
If you disable this option, client stations will have to specify the network name you enter for
Name (SSID) when they connect.
Advertise Tx power
When this option is enabled, APs broadcast their current transmit power setting in the wireless
beacon. It also enables support for 802.11h and 802.11d.
Broadcast filtering
Use this option to conserve wireless bandwidth by filtering out non-essential broadcast traffic.
When broadcast filtering is enabled:
• DHCP broadcast requests are never forwarded on the wireless port.
• DHCP broadcast offers are never forwarded on the wireless port unless the target of the
offer is an associated client on the wireless interface.
• ARP broadcast requests are never forwarded out the wireless port unless the target of the
ARP request is an associated client on the wireless interface.
Broadcast filtering should be disabled in the following cases:
• An external DHCP server is connected to the wireless network.
• If a wireless client bridge is connected to the wireless network.
Band steering
Supported on: MSM422, HP 425, MSM430, MSM460, MSM466, MSM466-R
Band steering is used to help solve dense client issues. When band steering is enabled, APs
attempt to move wireless clients that are capable of 802.11a/n onto the 5 GHz band, thus
reducing the load on the slower and more crowded 2.4 GHz band, leaving it for less capable
legacy (802.11b/g) clients.
