Spectrum Intelligence

Configure spectrum intelligence (CLI)

Enable network administrators to monitor and analyze the radio frequency (RF) environment by configuring the Spectrum Intelligence (SI) feature on Cisco APs.

Follow the procedure given below to configure spectrum intelligence:

Procedure

Step 1

Enter the global configuration mode.

Example:

Device# configure terminal

Step 2

Configure the 2.4-GHz or 5-GHz spectrum intelligence feature on the 802.11a or 802.11b network.

Example:

Device(config)# ap dot11 {24ghz | 5ghz} SI

Add no form of the command to disable SI on the 802.11a or 802.11b network.

Verify spectrum intelligence information

Use these commands to verify spectrum intelligence information:

To display the SI information for a 2.4-GHz or 5-GHz band, use this command:

Device# show ap dot11 24ghz SI config
                
SI Solution...................................... : Enabled
Interference Device Settings:
SI_FHSS.................................. : Enabled
Interference Device Types Triggering Alarms:
SI_FHSS.................................. : Disabled

To display SI interferers of type continuous transmitter for a 2.4-GHz band, use this command:

Device# show ap dot11 24ghz SI device type cont_tx
                
DC    = Duty Cycle (%)
ISI = Interference Severity Index (1-Low Interference, 100-High Interference)
RSSI  = Received Signal Strength Index (dBm)
DevID = Device ID
AP type = CA, clean air, SI spectrum intelligence
No  ClusterID       DevID  Type     AP Type AP Name                 ISI  RSSI  DC   Channel
--- --------------- ------ -------- ------- ----------------- ---- ----- ----  ---  ------
xx:xx:xx:xx  0014  BT     CA    myAP1              --   -69 00  133
xx:xx:xx:xx  0014  BT     SI    myAP1              --   -69 00  133

To display 802.11a interference devices information for the given AP for 5-GHz, use this command:

Device# show ap dot11 5ghz SI device type ap
                
DC    = Duty Cycle (%)
ISI   = Interference Severity Index (1-Low Interference, 100-High Interference)
RSSI  = Received Signal Strength Index (dBm)
DevID = Device ID
AP type = CA, clean air, SI spectrum intelligence
No  ClusterID/BSSID    DevID  Type    AP Type AP Name                 ISI  RSSI  DC   Channel
--- ------------------ ------ ------- ------  ------------------------ ---- ----- ---- ----------

To display all Cisco CleanAir interferers for a 2.4-GHz band, use this command:

Device# show ap dot11 24ghz cleanair device type all
