Configure and manage Fluidity frequency scan commands on the device using CLI.

This task enables you to set up and manage Fluidity frequency scan functionality on the device to optimize wireless connectivity and performance.

Fluidity frequency scan allows the device to automatically monitor and switch between different wireless channels to maintain optimal connectivity. This functionality helps ensure consistent network performance by scanning for better connectivity options when signal strength falls below configured thresholds.

Procedure

1.

Use the configure fluidity scan list clear command to clear the Fluidity frequency scan list on the device.

Example:

Device# configure fluidity scan list clear
2.

Use the configure fluidity scan list channel-numbers bandwidth command to configure the list of channels and their bandwidths for Fluidity frequency scan.

Example:

Device#configure fluidity scan list 100 20 108 20
3.

Use the configure fluidity scan isolation value command to configure the isolation time for Fluidity frequency scan.

Example:

Device# configure fluidity scan isolation 3000

  • The isolation time valid range is from 0 to 65535.

  • When the signal strength falls below a certain SNR threshold value for a continuous period of 3000 milliseconds, the device initiates scanning for better connectivity options.

  • Use the configure fluidity scan isolation disabled command to disable the Fluidity frequency scan isolation mode on the device.
4.

Use the configure fluidity scan rssi-threshold threshold command to configure the SNR threshold for Fluidity frequency scan isolation mode.

Example:

Device# configure fluidity scan rssi-threshold 50

  • The device connects only to infrastructure devices that meet the specified minimum signal strength.

  • The SNR threshold value valid range is from 0 to 100.

  • Use the configure fluidity scan rssi-threshold disabled command to disable the SNR threshold.
5.

Use the configure fluidity scan periodic scan-time command to configure the periodic scan time on the device.

Example:

Device# configure fluidity scan periodic 5000

  • The specified time interval is in milliseconds.

  • The periodic scan time valid range is from 0 to 65535. For best results, the minimum recommended value is 1500. This value should consider the number of channels configured.

  • Use the configure fluidity scan periodic disabled command to disable the periodic frequency scan.
6.

Configure onboard radios Fluidity frequency allocation based on your requirements:

  • On the same channel: Use the configure fluidity scan vehicle-frequency locked command to lock the radio interfaces of onboard devices to operate on the same channel.

    Device#configure frequency scan vehicle-frequency locked

  • On the separate channels: Use the configure fluidity scan vehicle-frequency open command to allow radio interfaces of onboard devices to operate on the separate channels.

    Device#configure fluidity scan vehicle-frequency open
