Split 5 GHz Radio for 550 Series Access Points

Split 5 GHz Gigahertz. radio is an Instant feature that leverages the power of software to provide three radios on supported access points. The split 5 GHz Gigahertz. radio feature splits the 8X8 5 GHz Gigahertz. radio of the supported access points into two 4X4 5 GHz Gigahertz. radios operating on the upper and the lower part of the radio antenna offering three radios available for configuration - radio 0 (5 GHz Gigahertz.), radio 1 (2.4 GHz Gigahertz.) and radio 2 (5 GHz Gigahertz.). Radio 0 operates on the lower band Band refers to a specified range of frequencies of electromagnetic radiation. and Radio 2 operates on the upper band Band refers to a specified range of frequencies of electromagnetic radiation. of the 5 GHz Gigahertz. radio. The three radios of the AP can be deployed in either of the configuration modes- Access, Air Monitor and Spectrum monitor. The default mode of these radios is access.

The dot11a-secondary-radio-profile is the configuration profile for radio 2. This profile is active when tri-radio is enabled on the AP. The dot11a-radio-profile, profile of radio 0, will be used as default by the dot11a-secondary -radio-profile, radio 2, when split 5 GHz Gigahertz. radio is enabled. The secondary radio profile supports all configurations available in dot11a-radio-profile including RF Radio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. zones.

Certain existing configuration parameters do not apply when split 5 GHz Gigahertz.-radio is configured. The a-channel and g-channel configuration to set channel power of the radio no longer takes effect. In their place radio-0-channel, radio-1-channel and radio-2-channel commands are used to configure the channel and transmission power of the respective radios.

Feature Limitations

Client Match does not work when split 5 GHz Gigahertz. radio mode is enabled on the access point.

Mesh is supported but only radio0 can be used as the mesh radio.

Split 5 GHz Gigahertz. mode is only supported with APs powered by DC, PoE Power over Ethernet. PoE is a technology for wired Ethernet LANs to carry electric power required for the device in the data cables. The IEEE 802.3af PoE standard provides up to 15.4 W of power on each port. BT or dual shared PoE Power over Ethernet. PoE is a technology for wired Ethernet LANs to carry electric power required for the device in the data cables. The IEEE 802.3af PoE standard provides up to 15.4 W of power on each port. AT power supply.

Access points require reboot to enable or disable Split 5 GHz Gigahertz. radio mode in mesh deployments.

The following procedure configures the split 5 GHz Gigahertz. radio mode on the Instant AP,

1. Navigate to Configuration> Access Points page and select the Access Point > edit > Radio accordion.

2. Select Enable from the Split 5GHz mode drop down list box to enable the split 5 GHz Gigahertz. radio mode. To disable the feature, select Disable from the Split 5GHz mode. The default option is disabled.

3. The Radio 2 settings are now available for configuration under the Radio 2 accordion.

4. Choose a radio mode from the Mode drop-down list box.

5. Select a channel assignment method

Adaptive Radio Management assigned - If this option is selected the channels for the radio is intelligently assigned by the access point.

Administrator Assigned - If this option is selected, select the channel and the transmit Power in the Channel and Transmit power fields.

6. Click Save.

To configure split 5 GHz Gigahertz. radio mode for all supported APs in the network cluster.

1. Navigate to Configuration> Networks page and select Show advanced options.

2. Under General, toggle the Split 5GHz mode switch to enable or disable Split 5 GHz Gigahertz. mode globally for supported APs in the network. The default option is disabled.

3. Click Save.

To configure the radio profile settings for the secondary 5 GHz Gigahertz. radio,

1. Navigate to Configuration > RF > Show advanced options>Radio accordion.

2. Click + in the Secondary 5GHz band table and define the radio settings for the secondary 5 GHz Gigahertz. radio. For information on configuration parameters for the radio profile, see “Configuring Radio Settings” on page 1.

3. Click OK.

The following configurations do not require an AP reboot to take effect.

Configuring Split 5 GHz Radio

The following command is a global configuration and a per-ap command. When configured globally, all supported APs will work in the split 5 GHz Gigahertz. mode. To disable split 5 GHz Gigahertz. radio on selected APs override the global setting using the per-ap command. The per-ap command takes priority over the global configuration. The default value for this command is disabled.

To enable the split 5 GHz Gigahertz. feature, use the split-5ghz-mode enabled command.

(Instant AP) # split-5ghz-mode enabled

To disable the split 5 GHz Gigahertz. feature, use the split-5ghz-mode disabled or no split-5ghz-mode command.

(Instant AP) # split-5ghz-mode disabled

(Instant AP) # no split-5ghz-mode

To configure radio profile settings of radio2, use the rf dot11a-secondary-radio-profile <name> command. The secondary profile is active only when split 5 GHz Gigahertz. radio is enabled on the AP. The values of the dot11a-radio-profile is used as default by the secondary radio profile.

(Instant AP) # rf dot11a-secondary-radio-profile <name>

See Aruba Instant 8.6.0.x CLI Reference Guide for information on configurable parameters.

Enabling/ Disabling radios

When split 5 GHz Gigahertz. radio is enabled, use the radio-0-disable, radio-1-disable and radio-2-disable commands to disable the respective radios.

(Instant AP) # radio-1-disable

(Instant AP) # radio-2-disable

Radio Channel and Transmission Power

When tri-radio is enabled, use the radio-0-channel, radio-1-channel and radio-2-channel to configure the static channel and transmission power for the respective radios. Please note radio0 and radio2 supports 5 GHz Gigahertz. channels and radio1 supports 2.4 GHz Gigahertz. channels.

(Instant AP) # radio-0-channel <36-64>

(Instant AP) # radio-1-channel <1-11>

(Instant AP) # radio-2-channel <100-161>

Radio Mode

When split 5 GHz Gigahertz. radio is enabled, the wifi2-mode command is available to configure the mode for radio2. This command is a per-ap setting.

(Instant AP) # wifi2-mode <monitor | spectrum | access>
