ABSTRACT:
First and second management systems are placed in active and standby modes, respectively. The first and second management systems are configured to be in communication with the second and the first management systems, respectively and with a plurality of network devices. A first number of the plurality of network devices in communication with the first management system is determined at the first management system and transmitted to the second management system. A second number of the plurality of network devices in communication with the second management system is determined at the second management system and transmitted to the first management system. A first determination is made regarding whether the first number of network devices is less than the second number of network devices at the first management system. A second determination is made regarding whether the first number of network devices is less than the second number of network devices at the second management system. The first and second management systems are placed in failure mode and active mode, respectively based on the first and second determinations.
