Switch Alerts
Aruba Central allows you to configure and enable the following switch alerts:
—Generates an alert when a new switch is connected.
—Generates an alert when a switch is disconnected. This alert is enabled by default and the alert severity is . In the field, enter the duration after which the alert must be generated. The default value is 10 minutes.
—Generates an alert when there is a mismatch in switch configuration.
—Generates an alert when the switch hardware fails. The following are the typical hardware failures for Aruba and MAS 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 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. 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.
Fan failure.
High temperature.
—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 field, enter the duration after which the alert must be generated. You can add additional rule(s) for this alert.
—Generates an alert when the switch memory utilization exceeds the threshold value. In the field, enter the duration after which the alert must be generated. You can add additional rule(s) for this alert.
—In the drop-down, select either or . Select to generate an alert if the data transmission rate of the port (in terms of MbpsMegabits per second) exceeds the threshold value. Select 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 field, enter the interface name. You can add additional rule(s) for this alert.
—In the drop-down, select either or . Select to generate an alert if the data reception rate of the port (in terms of Mbps) exceeds the threshold value. Select 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 field, enter the interface name. You can add additional rule(s) for this alert.
—Generates an alert when the percentage of input errors on the port exceeds the threshold value. In the field, enter the interface name. You can add additional rule(s) for this alert.
—Generates an alert when the percentage of output errors on the port exceeds the threshold value. In the field, enter the interface name. You can add additional rule(s) for this alert.
—Generates an alert when the port is operating in half-duplex mode. In the field, enter the interface name.
—Generates an alert when the PoE 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.
—Generates an alert when a switch configured as the Spanning Tree Protocol (STPSpanning Tree Protocol. STP is a network protocol that builds a logical loop-free topology for Ethernet networks.) root is replaced by another switch in the LANLocal Area Network. A LAN is a network of connected devices within a distinct geographic area such as an office or a commercial establishment and share a common communications line or wireless link to a server.. This alert is enabled by default and the alert severity is Major.
—Generates an alert when a stack member is added or removed. This alert is enabled by default and the alert severity is Major.
—Generates an alert when there is a change in Stack commander. This alert is enabled by default and the alert severity is .
