If a vswitch has a downlink switch on its port, because the switch supports multiple MAC addresses, the lower-level MAC address is recorded in the upper-level MAC table, therefore, first look for the MAC table of the upper-level switch, determine the specific location, and then look for the next-level switch, which will greatly reduce the search range. Use
