AOS-Switch Alerts

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

Following are the AOS-Switch alerts that you can configure.

  • New Switch Connected—Generates an alert when a new switch is connected.
  • Switch Disconnected—Generates an alert when a switch is disconnected. This alert is enabled by default and the alert severity is Major. In the Duration field, enter the duration during which the condition persists. The alert must be generated if the condition persists even after this duration. The default value is 10 minutes.
  • Switch Mismatch Config—Generates an alert when there is a mismatch in switch configuration.
  • Switch CPU Utilization—Generates an alert when the switch CPUCentral 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 rule(s) for this alert.
  • Switch Memory Utilization—Generates an alert when the switch memory utilization exceeds the threshold value. In the Duration field, enter the duration after which the alert must be generated. You can add additional rule(s) for this alert.
  • Switch Port Tx Rate—In the Transform Function drop-down, select either absolute or percentage. Select absolute to generate an alert if the data transmission rate of the port (in terms of MbpsMegabits per second) exceeds the threshold value. Select percentage to generate an alert if the data transmission rate of the port (in terms of utilization as a percentage of total bandwidth available) exceeds the threshold value. In the Interface field, enter the interface name. You can add additional rule(s) for this alert.
  • Switch Port Rx Rate—In the Transform Function drop-down, select either absolute or percentage. Select absolute to generate an alert if the data reception rate of the port (in terms of Mbps) exceeds the threshold value. Select percentage to generate an alert if the data reception rate of the port (in terms of utilization as a percentage of total bandwidth available) exceeds the threshold value. In the Interface field, enter the interface name. You can add additional rule(s) for this alert.
  • Switch Port Input Errors—Generates an alert when the percentage of input errors on the port exceeds the threshold value. In the Interface field, enter the interface name. You can add additional rule(s) for this alert.
  • Switch Port Output Errors—Generates an alert when the percentage of output errors on the port exceeds the threshold value. In the Interface field, enter the interface name. You can add additional rule(s) for this alert.
  • Switch Port Duplex Mode—Generates an alert when the port is operating in half-duplex mode. In the Interface field, enter the interface name.
  • Switch PoE Utilization—Generates an alert when the PoEPower over Ethernet. PoE is a technology for wired Ethernet LANs to carry electric power required for the device in the data cables. The IEEE 802.3af PoE standard provides up to 15.4 W of power on each port. utilization for a port exceeds the critical and major threshold value. This alert is enabled by default and the alert severity is Critical. You can add additional rule(s) for this alert.
  • Switch Hardware Failure—Generates an alert when the switch hardware fails. The following are the typical hardware failures for Aruba and MAS switches:

    MAS switches

    • Fan failure
    • High temperature

    Aruba switches

    • Fan failure
    • Power supply failure
    • Redundant power supply failure
    • High temperature
    • Management module failures—Management module failed self-test or lost communication with management module
    • Slot failure—Lost communications detected, slot self-test failure or unsupported module, or chassis hot swap failure
    • Fabric power failure
    • Internal power supply: Fan failure
    • Internal power supply failure
    • Internal power supply main PoE power failure
    • Internal power supply: Main inlet exceeds/within total fault count
    • Bad driver—Too many undersized/giant packets
    • Bad transceiver—Excessive jabbering
    • Bad cable—Excessive CRCCyclic Redundancy Check. CRC is a data verification method for detecting errors in digital data during transmission, storage, or retrieval. /alignment errors
    • Too long cable—Excessive late collisions
    • Over bandwidth—High collision or drop rate
    • Broadcast storm—Excessive broadcasts
    • Duplex mismatch HDx—Duplex mismatch. Reconfigure to Full Duplex
    • Duplex mismatch FDx—Duplex mismatch. Reconfigure port to Auto
    • Link flap—Rapid detection of link faults and recoveries
  • Switch STP Root Change—Generates an alert when there is a change in the Spanning Tree Protocol (STPSpanning Tree Protocol. STP is a network protocol that builds a logical loop-free topology for Ethernet networks.) root. This alert is enabled by default and the alert severity is Major.
  • Switch Uplink Port Usage—Generates an alert when the total uplink port usage of a switch at a site exceeds the configured value in gigabytes (GB) within a specified duration. The severity for this alert is Warning. In the exceeds field, enter the uplink port usage value in GB. In the Duration field, enter the duration after which the alert occurs. The alert must be generated if the condition persists even after this duration.
