AOS-CX 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-CX switch alerts that you can configure:

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

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 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 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 Mbps) 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 PoE Power 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 Uplink Port Status Change—Generates an alert when there is a change in the status of the uplink port. This alert is generated when the uplink port goes down and it is cleared when the port status is restored.
Stack Member Added/Removed—Generates an alert when a stack member is added or removed. This alert is enabled by default and the alert severity is Major.
Switch Stack Conductor Change—Generates an alert when there is a change in the stack conductor. This alert is enabled by default and the alert severity is Major.
Stack Link Status Change—Generates an alert when there is a change in the VSF Virtual Switching Framework. VSF allows network administrators to stack multiple individual switches into a single logical device using standard Ethernet links. link between stack members. This alert is disabled by default and the alert severity is Major. This alert is generated and displayed in the Open Alerts tab when the VSF link goes down. However, the same alert will be acknowledged and displayed in the Acknowledged Alerts tab when the VSF link is restored or enabled.

Switch Hardware Failure—Generates an alert when the switch hardware fails. The following are the typical hardware failures for AOS-CX switches:
- Endurance Storage Utilization Failure (eMMC)—Generates an alert when the eMMC storage reaches critical utilization levels.
- Critical hardware faults
  This alert is supported only on the AOS-CX 6200 and 6300 Switch Series.
- Thermal alerts—Platform temperature crossed the lower or higher threshold.
  This alert is supported only on the AOS-CX 4100i, 6100, 6200, 6300, 8320, 8360, 9300, and 10000 Switch Series running firmware version 10.10.1000 or later. For the 8400 and 6400 Switch Series, this alert is supported from 10.11.1000 or later versions.
- Management module failure—Generates an alert when the state of the management module changes to down or failed.
- Line-card failure—Generates an alert when the state of the line card changes to down or failed.
- Fan tray failure—Generates an alert when the state of the fan tray in the slot changes to down or failed.
- Fan failure—Generates an alert when the state of the fan in the slot tray changes to fault.
- Power supply failure—Generates an alert when the state of the power supply in the slot changes to fault input or warning.
Switch NAE Status—Generates an alert when the NAE Status for the AOS-CX switches exceed the Normal value, based on the severity configured. This alert is disabled by default and the alert severity is Major. If you want to generate alerts for the NAE Status of value Disabled, then set the alert severity to Warning.
Switch NAE Network Analytics Engine. The NAE feature within AOS-CX switches is a framework for automating the detection of issues and automating root cause analysis. Agent Status—Generates an alert when an NAE agent hits a condition that requires to be reported. This alert is disabled by default. This alert is supported only on AOS-CX switches running 10.13.1000 or later versions. This alert is generated only for the following NAE agent scripts:
- routing_health_monitor
- EVPN_VXLAN Virtual Extensible LAN creates virtual networks overlaid on a physical network.
- Client Services
- VSF_agent
- VSX Virtual Switching Extension. VSX is a virtualization technology for aggregation/core switches running the AOS-CX operating system. This solution lets the switches present as one virtualized switch in critical areas.
- default_agent
Switch Routing Neighbor Status Change—Generates an alert when the current status of the BGP Border Gateway Protocol. BGP is a routing protocol for exchanging data and information between different host gateways or autonomous systems on the Internet. neighbor changes from up (established) to down and it is cleared when the status changes back to up (established). This alert is disabled by default and the alert severity is Critical.
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) within the specified duration. This alert is disabled by default and the alert severity is Major. 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 is generated if the condition persists even after this duration.
Switch Reboot (AOS-CX)—Generates an alert when a switch reboots, crashes, or when the Redundancy Switchover action is executed on the active module in the switch.
Reboot alerts are generated for devices with firmware greater than 10.10.1000 with a reboot history of less than 30 minutes from the time they are connected / last connected to Aruba Central.
