Abstract: Examples disclosed herein relate to selection of a master controller in a software defined network (SDN). In an example, a master controller may monitor a parameter on each SDN controller in a team of SDN controllers comprising the master controller, wherein the master controller performs a role of master over a group of network devices. In response to a determination that a value of the parameter on the master controller is above a pre-defined limit, master controller may select another SDN controller from the team. Master controller may assign the role of master over network devices in the group to the selected SDN controller based on a ranking of the network devices, wherein the network devices may be assigned in succession until a limit defined for a value of the parameter on the selected SDN controller is reached.

Abstract: A system and method for real-time detection, identification, and reporting of mac-sync failures in distributed trunking (DT) are disclosed. In one example, a mac-sync failure between a pair of communicatively coupled DT switches is detected in real-time. Further, a type of mac-sync failure between the pair of DT switches is dynamically identified upon detecting the mac-sync failure. Furthermore, an information technology (IT) admin is dynamically notified about the type of mac-sync failure between the pair of DT switches.
