Maintain the MAC address table of cascade ports of two vswitches

Assume that the first 23 ports of vswitch A are connected to 23 computers and the MAC addresses are A1 to A23. The 24th ports of vswitch A are cascade with the 1st ports of vswitch B, after the MAC address of the system is learned, in the worksheet of Switch B, the 23 MAC addresses A1 to A23 are associated with the 1st ports.

In addition, vswitch B does not store the relationship between the 23 MAC addresses from A1 to A23 in the internal address table of vswitch A and the port of vswitch, vswitch B sends all the MAC addresses from A1 to A23 to its port 1.
