Access Points in Tri-Radio Mode

Aruba Central supports tri-radio mode in Aruba AP-555, a flagship 802.11ax access point (AP). In tri-radio mode or split 5 GHz Gigahertz. mode, the 8x8 5 GHz radio is split into two independent 4x4 5 GHz radios. In the tri-radio mode, the 5GHz Band operates on channels 36–64 and Second 5GHz Radio operates on channels 100–165.

The split 5 GHz radio can operate in the following modes:

  • Access
  • Monitor
  • Spectrum

When the tri-radio mode is either enabled or disabled in an AP, the Events table displays the following details:

  • The Event Type column includes the AP Tri-Radio type, which can be used to filter tri-radio events.
  • The Description column includes the status of the tri-radio mode in AP.

In Aruba Central, the tri-radio mode feature is available only for AP-555 access points running Aruba Instant or later versions. By default, the AP-555 operates in dual radio mode.
