AP Default Settings

If SNMP is enabled on the controller and you enable LLDP, the LLDP Confirmation dialog is displayed.

Select one of the following:

• Proceed (not recommended) — Enables LLDP and keeps SNMP (Simple Network Management Protocol) running.
• Disable SNMP publishing, and proceed — Enables LLDP and disables SNMP.
• For more information on using SNMP, see the Extreme Networks ExtremeWireless Maintenance Guide

The available radio settings are dependent on the radio mode you select.

• 20 MHz — Click to allow 802.11n clients to use the primary channel (20 MHz) and non-802.11n clients, beacons, and multicasts to use the 802.11b/g radio protocols.
• 40 MHz — Click to allow 802.11n clients that support the 40 MHz frequency to use 40 MHz, 20 MHz, or the 802.11b/g radio protocols. 802.11n clients that do not support the 40 MHz frequency can use 20 MHz or the 802.11b/g radio protocols and non-802.11n clients, beacons, and multicasts use the 802.11b/g radio protocols.
• 80 MHz — Click to allow 802.11ac clients to use the 80MHz frequency. Applies to AP38xx and AP39xx Radio 1 only.
• Auto — Click to automatically switch between 20 MHz, 40 MHz, and 80 MHz channel widths, depending on how busy the extension channels are.

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.

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.

When you configure 11n Wireless APs to use specific antennas, the transmission power is recalculated; the Current Tx Power Level value for the radio is automatically adjusted to reflect the recent antenna configuration. It takes approximately 30 seconds for the change to the Current Tx Power Level value to be reflected in the ExtremeWireless Assistant. Also, the radio is reset causing client connections on this radio to be lost.

Select the desired Secure Tunnel mode from the drop-down list:

• Disabled — Secure Tunnel is turned off and no traffic is encrypted. All SFTP/SSH/TFTP traffic works normally.
• Encrypt control traffic between AP & Controller — An IPSEC tunnel is established from the AP to the controller and all SFTP/SSH/TFTP/WASSP control traffic is encrypted. The AP skips the registration and authentication phases and when selected, the Secure Tunnel Lifetime feature can be configured.
• Encrypt control and data traffic between AP & Controller — This mode only benefits routed/bridged@Controller Topologies. An IPSEC tunnel is established from the AP to the controller and all SFTP/SSH/TFTP/WASSP control and data traffic is encrypted. The AP skips the registration and authentication phases, and when selected, the Secure Tunnel Lifetime feature can be configured.
  Note: This option is not available for AP3805 models.
• Debug mode — An IPSEC tunnel is established from the AP to the controller, no traffic is encrypted, and all SFTP/SSH/TFTP traffic works normally. The AP skips the registration and authentication phases and when selected, the Secure Tunnel Lifetime feature can be configured.

• If the AP is preparing to reboot or to enter one of the special modes (DRM initial channel selection).
• If a BSSID is deactivated or removed on the AP.

This option is disabled by default.

• Monitor Mode — If traffic or noise levels exceed the configured DCS thresholds, an alarm is triggered and an information log is generated.
• Active Mode — If traffic or noise levels exceed the configured DCS thresholds, an alarm is triggered and an information log is generated. In addition, the AP ceases operating on the current channel and ACS automatically selects an alternate channel for the AP to operate on.

(appears if Dynamic Channel Selection is enabled)

• Bluetooth
• Microwave
• Cordless Phone
• Constant Wave
• Video Bridge

• Click 1, 2, 5.5, or 11 Mbps for 11b and 11b+11g modes.
• Click 6, 12, or 24 Mbps for 11g-only mode.
• Click 6, 12, or 24 Mbps for 11a mode.

Tx Beam Forming is a technique of re-aligning the transmitter multipath spatial streams phases in order to get better signal-to-noise ratio on the receiver side. Click a TXBF mode: For the AP37xx and AP38xx models, valid values are Enabled or Disabled. For the 39xx APs, this setting is only available on Radio1 and valid values are MU-MIMO and Disabled.
