Access Point Alerts

Aruba Central allows network administrators and users with admin permissions to configure alerts. For more information, see Configuring Alerts.

To enable or disable all the access point alerts on a single click, you can use the Enable All or Disable All button respectively.

Following are the AP alerts that you can configure:

  • New Virtual Controller Detected—Generates an alert when a new virtual controller is detected.
  • Virtual Controller Disconnected—Generates an alert when a virtual controller is disconnected. This alert is enabled by default and the alert severity is automatically set to Major. To customize the alert trigger, enter a duration in minutes, in the Duration field. By default, the trigger to generate the alert is set to 10 minutes.
  • New AP Detected—Generates an alert when a new IAP is detected.
  • AP Disconnected—Generates an alert when an IAP is disconnected. This alert is enabled by default and the alert severity is automatically set to Major. To customize the alert trigger, enter a duration in minutes, in the Duration field. By default, the trigger to generate the alert is set to 15 minutes.
  • Rogue AP Detected—Generates an alert when a rogue IAP is detected. This alert is enabled by default and the alert severity is Major.
  • Infrastructure Attack Detected—Generates an alert when an infrastructure attack is detected.
  • Client Attack Detected—Generates an alert when a client attack is detected.
  • Uplink Changed—Generates an alert when an uplink has changed.
  • Modem Unplugged—Generates an alert when the modem is unplugged.
  • Modem Plugged—Generates an alert when the modem is plugged.
  • AP CPU Utilization—Generates an alert when the IAP CPU Central Processing Unit. A CPU is an electronic circuitry in a computer for processing instructions. utilization exceeds the threshold value. In the Duration field, enter the duration after which the alert must be generated. You can add additional rules for this alert.
  • AP Memory Utilization—Generates an alert when the IAP memory utilization exceeds the threshold value. In the Duration field, enter the duration after which the alert must be generated. You can add additional rules for this alert.
  • Insufficient Power Supplied—Generates an alert when the IAP is supplied with lesser power than the required power.
  • AP With Missing Radios—Generates an alert when the AP radio is faulty.
  • Radio Channel Utilization—Generates an alert when the IAP radio channel utilization exceeds the threshold value. In the Duration field, enter the duration after which the alert must be generated. From the Band drop-down, select the spectrum band Band refers to a specified range of frequencies of electromagnetic radiation.: 2.4 GHz or 5 GHz or 6 GHz. You can add additional rules for this alert.
  • Radio Noise Floor—Generates an alert when the Noise Floor (dBm Decibel-Milliwatts. dBm is a logarithmic measurement (integer) that is typically used in place of mW to represent receive-power level. AMP normalizes all signals to dBm, so that it is easy to evaluate performance between various vendors.) exceeds the threshold value. In the Duration field, enter the duration after which the alert must be generated. From the Band drop-down, select the spectrum band: 2.4 GHz or 5 GHz or 6 GHz. You can add additional rules for this alert.
  • Connected Clients per VC—Generates an alert when the number of connected clients to the VC exceeds the threshold value. In the Duration field, enter the duration after which the alert must be generated. You can add additional rules for this alert.
  • Connected Clients per IAP—Generates an alert when the number of connected clients to the IAP exceeds the threshold value. You can enter the threshold value after which the alerts must be generated. The recommended value is 15 minutes and above. You can add additional rules for this alert.
  • Radio Frames Retry Percent—Generates an alert when the IAP radio frames retry percent exceeds the threshold value. In the Duration field, enter the duration after which the alert must be generated. From the Band drop-down, select the spectrum band: 2.4 GHz or 5 GHz or 6 GHz. You can add additional rules for this alert.
  • AP Tunnel Down—Generates an alert when a single L3 tunnel configured on the AP goes down.
  • All AP Tunnels Down—Generates an alert when all the L3 tunnels configured on the AP go down.
  • IAP Firmware Upgrade Failed—Generates an alert when there is any IAP upgrade failure such as, no firmware image is available or there is no response from the device.
  • Radio Non Wi-Fi Utilization—Generates an alert when the IAP radio non-Wi-Fi Wi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. utilization exceeds the threshold value. In the Duration field, enter the duration after which the alert must be generated. From the Band drop-down, select the spectrum band: 2.4 GHz or 5 GHz or 6 GHz. You can add additional rules for this alert.
  • AP Crash—Generates an alert when an AP crash is detected. It is only supported for CAP/ RAP devices.
  • AP Reboot—Generates an alert when an AP reboot is detected. It is only supported for CAP/ RAP devices.
  • Airgroup Cache Overflow—Generates an alert when cache records cross a specific limit and the AP is flooded. Memory on the AP is limited, so a maximum limit of 2k records on discovered-cache entries and 4k records on central-cache entries is set. This alert is generated for APs that run ArubaOS 10 or higher. It is only supported for IAP devices.
  • AP Routing Table Limit—Generates an alert when the number of routes on Microbranch solution reaches 80% of the maximum routes. The maximum number of routes supported is 512 out of which, 16 route entries are reserved for default and connected routes, leaving only 496 routes for protocol routes, static and overlay. This event is cleared when route table utilization goes below 70% of the total route table size.
  • DPP Device Provisioning Protocol. DPP is a provisioning protocol certified by the Wi-Fi Alliance that allows onboarding IoT devices easily, securely, and on a large scale. Attack—Generates an alert when there is a DPP-related DoS Denial of Service. DoS is any type of attack where the attackers send excessive messages to flood traffic and thereby preventing the legitimate users from accessing the service. attack in the network.
  • AP DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  Pool Consumption Alert—Generates a Microbranch IAP alert when the client uses an IP address from the AP DHCP Pool which exceeds the threshold value.
