Cisco Flexible Radio Assignment

Flexible radio assignment actions

Flexible Radio Assignment (FRA) evaluates 2.4-GHz radio coverage to identify overlapping coverage causing radio interference. If there is an overlapping coverage, the dual-band radio moves to either 5-GHz client serving or monitor role.

Feature information

Cisco IOS XE Dublin 17.10.1

Flexible Radio Assignment (FRA) Action

In Cisco IOS-XE 17.10.1 and earlier releases, the FRA moves the redundant dual-band radios to either 5-GHz client-serving role or monitor role.

Cisco IOS XE Dublin17.11.1

Flexible Radio Assignment (FRA) Action

From Cisco IOS-XE 17.11.1 onwards, you can select the redundant dual-band radios in a network to operate in monitor only mode.

Release Information

In Cisco IOS-XE 17.10.1 and earlier releases, the FRA moves the redundant dual-band radios to either 5-GHz client-serving role or monitor role. From Cisco IOS-XE 17.11.1 onwards, you can set redundant dual-band radios in a network to operate in monitor-only mode.


Note

The FRA action feature is disabled by default.

Configure FRA action in default RF profile (CLI)

Configure the FRA action in the default RF profile to optimize radio frequency management.

Procedure

Step 1

Configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

Configure the FRA action

Example:

Device(config)# ap dot11 24ghz fra action monitor

Configures the FRA action to monitor mode, moving all redundant dual-band APs solely to the monitor role.

Step 3

Exit configuration mode

Example:

Device(config)# end

Exits configuration mode and returns to privileged EXEC mode.

Upon completion, the FRA action is set, redundancy in dual-band radios is handled efficiently, and the system returns to privileged EXEC mode.

Configure FRA action in 2.4-GHz RF profile (CLI)

Procedure

Step 1

Configure terminal

Example:

Device# configure terminal

Enters global configuration mode

Step 2

Configure the RF profile name

Example:

Device(config)# ap dot11 24ghz rf-profile alpha-rfprofile-24ghz

Configures the RF profile name and enters RF profile configuration mode.

Step 3

Configure the FRA action as monitor

Example:

Device(config-rf-profile)# fra action monitor

Configures the FRA action as monitor, and moves all redundant dual-band radios to monitor role only.

Step 4

Exit configuration mode

Example:

Device(config-rf-profile)# end

Exits configuration mode and returns to privileged EXEC mode.
