802.11b/g Global Parameters

Use WIRELESS > Global RF > 802.11b/g Network to navigate to this page.

Use this page to edit the global parameters of your 802.11b/g network.

• 802.11b/g Network Status - Enable or Disable the 802.11b/g network.

• 802.11g Support - Enable or Disable 802.11g network support. (Only available if the 802.11b/g

Network is Enabled.)

Note You must use these commands to enable the 802.11b/g networks after configuring other 802.11b/g

parameters. Note that this command only enables the global Cisco WLAN Solution 802.11b/g networks.

To disable the 802.11a, 802.11b and/or 802.11g networks for an individual WLAN, refer to the WLANs

> Edit page.

• Data Rates - The data rates set here are negotiated between the client and the controller. If the data

rate is set to Mandatory, the client must support it in order to use the network. If a data rate is set as

Supported by the controller, the client may negotiate for the respective rate. Each data rate can also

be set to Disabled to match Client settings.

• Beacon Period - The rate at which the SSID is broadcast by the access point, from 100 to

600 milliseconds. Default 100 milliseconds.

• DTIM Period - 1 to 255 beacon intervals. The DTIM Period is the number of beacon intervals that

elapse between transmission of Beacon frames containing a TIM element whose DTIM Count field

is 0. Default 1 interval.

• Fragmentation Threshold - 256 to 2346 bytes. Default 2346.

• Short Preamble - Enabled or Disabled. This parameter must be disabled to optimize this controller

for some clients, including SpectraLink NetLink Telephones. Default Enabled.

• Pico Cell Mode - Enables automatic OS parameter reconfiguration, allowing OS to function

efficiently in pico cell deployments. Note that when the operator is deploying a pico cell network

the OS must also have more memory allocated (512 to 2048 MB) using the following command

config database size 2048

• DTPC Support—Enable this option to advertise the transmit power level of the radio in the beacons

and the probe responses.

Command Buttons

• Apply: Data is sent to the controller and made to take effect, but not preserved across a power cycle;

these parameters are stored temporarily in volatile RAM.

• Auto RF: Opens the page for the 802.11b/g Global Parameters > Auto RF.

• Help: Request that the help page be displayed in a new browser window.
