Defect Information

Defect ID Headline
CSCvy16347 DFS fails on Cisco FM1200 Volo radio transceivers

Problem Description

On Cisco Ultra-Reliable Wireless Backhaul (formerly Fluidmesh) FM1200 Volo radio transceivers, the Dynamic Frequency Selection (DFS) function might fail to detect Unlicensed National Information Infrastructure (U-NII) frequencies in client mode or might fail to cease emitting when a U-NII frequency is detected.

Background

On Cisco FM1200 Volo radio transceivers, the DFS function might fail to detect U-NII frequencies in client mode or might fail to cease emitting when a U-NII frequency is detected.

Cessation of transmission upon detection of U-NII frequencies is mandatory for proper use of the radio spectrum under Article 3.2 of European Union Directive 2014/53/EU, as well as under local country regulations within the European Union. This capability is also highly recommended for deployments outside the European Union.

Cisco has made improvements to the Time Division Multiple Access (TDMA) token passing algorithm used in the radios to reduce the TX duty-cycle on the wireless link when Fluidmax is enabled. As a result, Cisco strongly recommends that customers install and deploy firmware Version 7.9 and later (for FM1200 Volo) or Version 8.6 and later (for FM3200 and FM4200 radio series) to considerably improve the performance of the TDMA protocol when configured in a point-to-multipoint network.

For additional information, see the Firmware Release Notes.

Problem Symptom

The device will appear to work normally when TDMA is enabled, but will be out of compliance under Article 3.2 of European Union Directive 2014/53/EU and local country regulations.

Workaround/Solution

There is no workaround.

The solution is a mandatory upgrade of all FM1200 Volo, FM3200, and FM4200 radio series to the latest image available in Cisco Software Central.

Customers must complete these steps in order to upgrade the firmware:

  1. Ensure the radio's country selection is properly set to the country where the radio is physically installed.
  2. Upgrade the device to the latest firmware version from Cisco Software Central. Click Access downloads, enter Ultra Reliable Wireless Backhaul, and click Browse all. Choose the appropriate firmware version based on the radio series deployed:
    • Cisco Ultra Reliable Wireless Backhaul FM1200 Volo radio series - Firmware Version 7.9 and later
    • Cisco Ultra Reliable Wireless Backhaul FM3200 and FM4200 radio series - Firmware Version 8.6 and later
  3. For new radios that have not yet been configured and run a firmware version earlier than Version 7.8.4 or Version 8.5, reset the radio to the factory default configuration after you have completed steps 1 and 2.

The radio will now be ready to accept custom configuration settings.
