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.
