Radio Mode - Radio 2
Note: Depending on the radio modes you select, some of the radio settings may not be available for configuration.

Click one of the following radio options for Radio 2:

  • b — Click to enable the 802.11b-only mode of Radio 2. If selected, the AP uses only 11b (CCK) rates with all associated clients.
  • g — Click to enable the 802.11g-only mode of Radio 2.
  • b/g — Click to enable both the 802.11g mode and the 802.11b mode of Radio 2. If selected, the AP uses 11b (CCK) and 11g-specific (OFDM) rates with all of the associated clients and will not transmit or receive 11n rates.
  • g/n — Click to enable both the 802.11g mode and the 802.11nb mode of Radio 2. If selected, the AP uses 11n and 11g-specific (OFDM) rates with all of the associated clients. The AP will not transmit or receive 11b rates.
  • b/g/n — Click to enable b/g/n modes of Radio 2. If selected, the AP uses all available 11b, 11g, and 11n rates.
  • n-strict — Click to enable the 802.11n-strict mode of Radio 2. If selected, the AP can be configured to use 11n-strict rates with all of the associated clients. With n-strict mode enabled, the AP does not transmit or receive 11b or 11g rates.
Basic Radio Settings
RF Domain Type a string that uniquely identifies a group of APs that cooperate in managing RF channels and transmission power levels. The maximum length of the string is 16 characters. The RF Domain is used to identify a group of APs. The RF Domain feature is part of the Auto Tx Power Control (ATPC) feature (for more information, see Configuring Wireless AP Radio Properties).
Current Channel Read-only. The actual channel the ACS has assigned to the AP radio. The Current Channel value and the Last Requested Channel value may be different because the ACS automatically assigns the best available channel to the AP, ensuring that a AP‘s radio is always operating on the best available channel.
Last Requested Channel Read-only. The last wireless channel that you had selected to communicate with the wireless devices.
Request New Channel Click the wireless channel you want the wireless AP to use to communicate with wireless devices.

Weather channels (116, 120, 124, 128) are supported for European compliance. See Channel Plan.

Click Auto to request the ACS to search for a new channel for the AP, using a channel selection algorithm. This forces the AP to go through the auto-channel selection process again.

Note: ACS in the 2.4 GHz radio band with 40 MHz channels is not recommended due to severe co-channel interference.

Depending on the regulatory domain (based on country), some channels may be restricted. The default value is based on North America. For more information, see Regulatory Information.
Auto Tx Power Ctrl (ATPC) Click to either enable or disable ATPC from the Auto Tx Power Ctrl drop-down list. ATPC automatically adapts transmission power signals according to the coverage provided by the AP. After a period of time, the system stabilizes itself based on the RF coverage of your Wireless APs.
Note: When enabled, Min Tx Power and Auto Tx Power Ctrl Adjust parameters can be edited, and the ATPC algorithm will adjust the AP power between Max Tx power and Min Tx Power. When disabled, the Max Tx Power selected value or the largest value in the compliance table will be the power level used by the radio, whichever is smaller.
Current Tx Power Level The actual Tx power level used by the AP radio.
Max Tx Power Displays dynamic power level based on channel selected. Select the Max TX Power from the drop-down list. The values in the Max TX Power drop-down are in dBm and will vary by AP. The values are governed by compliance requirements based on the country, radio, and antenna selected. Changing this value below the current Min Tx Power value will change the Min Tx Power to a level lower than the selected Max TX Power.
Note: If Auto Tx Power Ctrl (ATPC) is disabled, the selected value or the largest value in the compliance table will be the power level used by the radio, whichever is smaller.
Min Tx Power If ATPC is enabled, select the minimum Tx power level that is equal or lower than the maximum Tx power level. Extreme Networks recommends that you use 0 dBm if you do not want to limit the potential Tx power level range that can be used.
Note: The Min Tx Power setting cannot be set higher than the Max Tx Power setting.
Auto Tx Power Ctrl Adjust The Auto Tx Power Ctrl Adj parameter is a correction parameter that allows you to manually adjust (up or down) the Tx Power calculated by the ATPC algorithm. If ATPC is enabled, click the Tx power level that can be used to adjust the ATPC power levels that the system has assigned. It is recommended that you use 0 dBm during the initial configuration. If you have an RF plan that recommends Tx power levels for each AP, compare the actual Tx power levels your system has assigned against the recommended values your RF plan has provided. Use the Auto Tx Power Ctrl Adjust value to achieve the recommended values. Valid range is from - (Max Tx Power - Min Tx Power) dB to (Max Tx Power - Min Tx Power) dB.
Channel Plan - Radio 1
If ACS is enabled you can define a channel plan for the AP. Defining a channel plan allows you to control which channels are available for use during an ACS scan. For example, you may want to avoid using specific channels because of low power, regulatory domain, or radar interference.
  • For 5 GHz Radio nodes, click one of the following:
    • All channels — ACS scans all channels for an operating channel and returns both DFS and non-DFS channels, if available.
    • All Non-DFS Channels — ACS scans all non-DFS channels for an operating channel.
    • Custom — To configure individual channels from which the ACS will select an operating channel, click Configure. The Custom Channel Plan dialog displays. By default, all channels participate in the channel plan. Click the individual channels you want to include in the channel plan. To select contiguous channels, use the Shift key. To select multiple, non-contiguous channels in the list, use the CTRL key. Click OK to save the configuration.
    • All channels including weather radar — ACS scans all channels for an operating channel and returns all channels including weather radar channels. (This option is supported in Europe only).
      • The weather channel includes 5600-5650MHz sub-bands and requires a 10-minute listening period before the AP can provide wireless service. During the listening period, the Current Channel field for DFS channels displays the value DFS Timeout, and the weather channel fields display DFS Timeout 10 minutes.
  • For 2.4 GHz Radio nodes, click one of the following:
    • 3 Channel Plan — ACS scans the following channels: 1, 6, and 11 in North America, and 1, 7, and 13 in the rest of the world.
    • 4 Channel Plan — ACS scans the following channels: 1, 4, 7, and 11 in North America, and 1, 5, 9, and 13 in the rest of the world.
    • Auto — ACS scans the default channel plan channels: 1, 6, and 11 in North America, and 1, 5, 9, and 13 in the rest of the world.
    • Custom — If you want to configure individual channels from which the ACS selects an operating channel, click Configure. The Add Channels dialog is displayed. Click the individual channels you want to add to the channel plan while pressing the CTRL key, and then click OK.
