What does the Flagged AP section on the Access Point page of Aruba Central Dashboard show? What are the possible reasons due to which Aruba Central may flag an AP?

Aruba Employee
Environment This article applies to all the Instant Access Points running ArubaOS version 6.2.1.0-3.3.0.0 or higher and managed by Aruba Central.

 

The Flagged AP section of the Access Point page lists all the IAPs that exceed the utilization, noise, or error threshold. It also shows the available free memory, CPU utilization, and number of clients associated with the APs.

 The FLAGGED AP section contains the following sub-sections:

   1. ACCESS POINTS

Displays the list of flagged access points managed by Aruba Central.
 

   2. UTIL(%)

Displays the utilization percentage of the access point's operating channel.

Depending on the percentage of utilization, the color of the lines on the Utilization icon changes from Green > Orange > Red.

  • Green   — Indicates less than 50 percent utilization.

  • Orange — Indicates 50-75 percent utilization.

  • Red      — Indicates more than 75 percent utilization.

To view the actual utilization value of an IAP, hover the mouse over utilization icon next to the IAP in the utilization column.
 

   3. NOISE (dBm)

Displays the noise floor of the access point channel (dBm).

Noise is measured in decibels/meter. Depending on the noise floor, the color of the lines on the Noise icon changes from Green > Orange > Red.

  • Green— Indicates the noise floor that is more than 87 dBm.

  • Orange— Indicates the noise floor that ranges from 80 dBm-87 dBm.

  •  Red— Indicates the noise floor less than 80 dBm.

To view the actual noise value of an IAP, hover the mouse over the noise icon next to the IAP in the noise column.

   4. ERRORS

Displays the bit error percentage per second for the access point. This is the stream of data that have been altered to due noise, distortion, and other factors.

Depending on the errors, color of the lines on the Errors icon changes from Green > Orange > Red.

  • Green— Indicates the errors that are less than 5000 frames per second.

  • Orange— Indicates the errors that ranges from 5000-10000 frames per second.

  • Red— Indicates the errors that are more than 10000 frames per second.

To view the actual error value of an IAP, hover the mouse over the Errors icon next to the IAP in the Errors column.

   5. CLIENTS

Displays the number of clients currently associated with the access point. An access point can potentially be flagged if there are excessive number of clients connecting to this AP compared to the rest of the APs in the cluster.
 

   6. MEMORY

Displays the memory availability of the IAP (MB).

Depending on the memory availability, color of the lines on the memory icon changes from Green > Orange > Red.

  • Green— Indicates that the memory available is more than 50 percent.

  • Orange— Indicates that the memory available is between 20-50 percent.

  • Red— Indicates that the memory available is more than 20 percent.

To view the actual memory availability of an IAP, hover the mouse over the Memory icon next to the IAP in the memory column.
 

   7. CPU

Displays CPU utilization for an IAP.       

Depending on the CPU utilization, color of the lines on the CPU icon changes from Green > Orange > Red.

  • Green— Indicates less than 50 percent CPU utilization.

  • Orange— Indicates 50-80 percent CPU utilization.

  • Red— Indicates more than 80 percent CPU utilization.

To view the actual CPU utilization of an IAP, hover the mouse over the CPU icon next to the IAP in the CPU column.
