Why Do MAC Address Entries Need to Be Synchronized Between Boards and What Are the Functions of Real-Time Synchronization and Periodic Synchronization?

Why Do MAC Address Entries Need to Be Synchronized Between Boards and What Are the Functions of Real-Time Synchronization and Periodic Synchronization?

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.
