Device Groups

A Device Group can be used to create a Mitigator Group or a Detector Group.

The Device Groups page displays a list of devices. You can select a set of devices to create a new mitigator group or a detector group. You can also add devices to an existing device group or delete a device group.

A mitigator group helps to streamline the configuration process. For example, you could push a config file to all devices in the group at once.

A detector group helps to ensure a reliable operation and provides redundancy of the detectors for a zone. In case of a failure of one of the detectors, the Detector Group ensures A10 Defend Orchestrator App continues to receive DDoS detection events from the other detectors in the group and thus achieve uninterrupted DDoS Protection.

When a detector group is associated to a zone, all the detectors within the group will receive xFlow (sFlow or NetFlow) traffic from the edge router for traffic monitoring. If any of the detectors within the group detects an attack or an increase in the configured threshold, it sends an escalation notification to A10 Defend Orchestrator App, and then A10 Defend Orchestrator App will create an incident and start the mitigation.

NOTE:

At least, one device group must be created and used as a mitigator group or a detector group.
