Abstract
In some examples, a first controller of a cluster of controllers provides a first controller network address assignment service for a first collection of client devices. The first controller detects a communication interruption with a second controller of the cluster of controllers, and determines whether a second controller network address assignment service of the second controller is unavailable, based on a determination of whether a network address assignment was performed within a specified recent time interval at the second controller. Based on determining that the second controller network address assignment service of the second controller is unavailable, the first controller transitions to a partner down state as part of a network address assignment failover in which the first controller provides the first controller network address assignment service for the first collection of client devices and for a second collection of client devices associated with the second controller.
