Parameters

smart-ocs-monitoring {awareness-override schedule <1-3> <START-TIME> <END-TIME> <DAY>}

schedule <1-3> <START-TIME> <END-TIME> {<DAY>} Configures a time and day schedule when awareness settings are overridden
  • <1-3> – Sets the awareness override schedule index. A maximum of three overrides can be configured.
    • <START-TIME> – Sets the override start time in HH:MM format
    • <END-TIME> – Sets the override end time in HH:MM format
      • DAY – Optional. Set the day when the override is active. Use one of the following formats:
        • all – Override is active on all days
        • sun – Override is active only on Sundays

        • fri – Override is active only on Fridays
        • sat – Override is active only on Saturdays
 
smart-ocs-monitoring {awareness-override threshold <10-10000>}
awareness-override threshold <10-10000> Optional. Use this parameter to configure client awareness settings overrides
  • threshold – Specifies the threshold after which client awareness settings are overridden. When the specified threshold is reached, awareness settings are overridden.
    • <10-10000> – Specify a threshold value from 10 -10000. The default is 10.
 
smart-ocs-monitoring {client-aware [2.4GHz|5GHz] <1-255>}
client-aware Optional. Enables client aware scanning on this Smart RF policy

Use this parameter to configure a client threshold number. When the number of clients connected to a radio equals this threshold number,

Use this parameter to configure a client threshold number. When the number of clients connected to a radio equals the specified threshold, the radio avoids channel scanning. The radio does not change channel even if needed (based on the interference recovery determination made by the smart master).

This feature is disabled by default.
2.4GHz <1-255> Enables client aware scanning on the 2.4 GHz band

Avoids radio scanning when a specified minimum number of clients are present

  • <1-255> – Sets the minimum number of clients from 1 - 255. The default is 50 clients.
5GHz <1-255> Enables client aware scanning on the 5.0 GHz band

Avoids radio scanning when a specified minimum number of clients are present

  • <1-255> – Sets the minimum number of clients from 1 - 255. The default is 50 clients.

 
smart-ocs-monitoring {extended-scan-frequency [2.4GHz|5GHz] <0-50>}
extended-scan-frequency Optional. Enables an extended scan, as opposed to a neighbor only scan, on this Smart RF policy. This is the frequency radios use to scan for non-peer radios.
2.4GHz <0-50> Enables extended scan on the 2.4 GHz band
  • <0-50> – Sets the number of trails from 0 - 50. The default is 5.
5GHz <0-50> Enables extended scan on the 5.0 GHz band
  • <0-50> – Sets the number of trails from 0 - 50. The default is 5.
 
smart-ocs-monitoring {frequency [2.4GHz|5GHz] <1-120>}
frequency Optional. Specifies the scan frequency. This is the frequency, in seconds, in which smart-ocs-monitoring changes channels for an off-channel scan.
2.4GHz <1-120> Selects the 2.4 GHz band
  • <1-120> – Sets a scan frequency from 1 sec - 120 sec. The default is 6 seconds.
5GHz <1-120>

Selects the 5.0 GHz band

  • <1-120> – Sets a scan frequency from 1 sec - 120 sec. The default is 6 seconds.
 
smart-ocs-monitoring {off-channel-duration [2.4GHz|5GHz] <20-150>}
off-channel-duration Optional. Specifies the duration to scan off channel

This is the duration for which an access point radio remains off-channel. During this period the radio monitors devices within the network and, if necessary, perform self healing and neighbor recovery to compensate for coverage area losses within a RF Domain.
2.4GHz <20-150> Selects the 2.4 GHz band (in milliseconds)
  • <20-150> – Sets the off channel duration from 20 - 150 milliseconds. The default is 50 milliseconds.
5GHz <20-150> Selects the 5.0 GHz band (in milliseconds)
  • <20-150> – Sets the off channel duration from 20 - 150 milliseconds. The default is 50 milliseconds.
 
smart-ocs-monitoring {power-save-aware [2.4GHz|5GHz] [disable|dynamic|strict]}
power-save-aware Optional. Enables power save awareness scanning mode on this Smart RF policy. The options are: disable, dynamic, and strict.

This setting allows Smart RF to detect power save clients and take them into consideration when performing off channel scans.

Strict disables smart monitoring as long as a power save capable client is associated to a radio. Dynamic disables smart monitoring as long as there is data buffered for a power save client at the radio.
2.4GHz [disable|dynamic|strict] Sets power save aware scanning mode on the 2.4 GHz band
  • disable – Disables voice awareness scanning
  • dynamic – Dynamically avoids scanning based on traffic for power save (PSP) clients. This is the default setting.
  • strict – Strictly avoids scanning when PSP clients are present
5GHz [disable|dynamic|strict] Sets power save aware scanning mode on the 5.0 GHz band
  • disable – Disables voice awareness .scanning

2.4GHz <1-15> Selects the 2.4 GHz band
  • <1-15> – Specifies the number of samples to collect from 1 - 15. The default is 10
5GHz <1-15> Selects the 5.0 GHz band
  • <1-15> – Specifies the number of samples to collect from 1 - 15. The default is 5.
 
smart-ocs-monitoring {tx-load-aware [2.4GHz|5GHz] <1-100>}
tx-load-aware Optional. Specifies a transmit load percentage that serves as a threshold before scanning is avoided for an access point‘s 2.4 GHz or 5.0 GHz band. This option is disabled for both 2.4 GHz and 5.0 GHz bands.
2.4GHz <1-100> Selects the 2.4 GHz band
  • <1-100> – Specify a transmit load percentage from 1 - 100%. When enabled, the default is 1%.
5GHz <1-100> Selects the 5.0 GHz band
  • <1-100> – Specify a transmit load percentage from 1 - 100%. When enabled, the default is 1%.
 
smart-ocs-monitoring {voice-aware [2.4GHz|5GHz] [disable|dynamic|strict]}
voice-aware Optional. Enables voice awareness scanning mode on this Smart RF policy. The options are: disable, dynamic, and strict.

Strict disables smart monitoring as long as a voice client is associated to a radio. Dynamic disables smart monitoring as long as there is data buffered for a voice client at the radio.
2.4GHz [disable|dynamic|strict] Specifies the scanning mode on the 2.4 GHz band
  • disable – Disables voice awareness scanning
  • dynamic – Dynamically avoids scanning based on traffic for voice clients. This is the default setting.
  • strict – Strictly avoids scanning when voice clients are present
5GHz [dynamic|strict] Specifies the scanning mode on the 5.0 GHz band
