Synchronizing MAC address entries ensures that most Layer 2 packets are forwarded based on MAC addresses, reducing broadcasts.
The functions of real-time synchronization and periodic synchronization are:
Real-time synchronization responds to MAC address changes quickly, but packet loss may occur during synchronization due to the limited processing capacity of the system.
Periodic synchronization synchronizes MAC address entries at an interval of several seconds. It works with real-time synchronization to ensure that all MAC addresses are synchronized and prevents aging of MAC address entries synchronized from other boards.
