How to Enable Tri-Radio Mode on AP555

Requirement:
ArubaOS Version: 8.6.0.0_73143
AP-555 which is 802.11ax AP with 8X8:8SS 5GHz radio and 4X4:4SS 2.4Ghz radio.

 

Overview:

In Tri-radio mode, the 8x8 5GHz radio is split into two independent 4x4 5GHz radios and is supported from 8.6 code.
Split 5Ghz Mode Radio 0 will operate on channels 36 to 64. Radio 2 will operate on channels 100 to 165.

 

Split 5Ghz radio can be in the following modes:
1. Both 5GHz radios to provide wireless access for clients.
2. One radio to provide wireless access, second radio acts as an AirMontior/SpectrumMonitor.
3. Both radios act as AirMonitors or SpectrumMonitors.

 

Power Consumption:
I have connected both E0 and E1 of AP555 to a 2930M Switch (1/35, 1/36)

Remember to configure lacp on the switch

By default the AP-555 operates in dual radio mode which means that the 5GHz radio is configured for 8*8:8 SS.

Radio 0 Band Ch/EIRP/MaxEIRP/Clients: AP:5GHz-HE:64-/21.0/23.0/0
Radio 1 Band Ch/EIRP/MaxEIRP/Clients: AP:2.4GHz-HE:1/12.0/29.4/1

Enabling Tri-Radio support:
In the AP-Group, Goto AP System Profile and change
Dual 5Ghz mode to Disabled

Split 5Ghz Mode to Enabled.AP-System_Profile.jpg

 

While enabling Tri-radio support, AP doesn't reboot.

Radio gets reset and Radio LED turns blue
Now the 5Ghz radio is split into two 4X4:4 radios and you can see 3 radios(2 x 5Ghz and 1 X 2.4Ghz) are servicing clients.3 radios.jpg

Radio 0 Band Ch/EIRP/MaxEIRP/Clients: AP:5GHz-HE:64-/21.0/23.0/1
Radio 1 Band Ch/EIRP/MaxEIRP/Clients: AP:2.4GHz-HE:1/12.0/29.4/0
Radio 2 Band Ch/EIRP/MaxEIRP/Clients: AP:5GHz-HE:112-/18.0/26.8/0
