Will the same MAC be input from different interfaces? switch processing?

예, but the MAC table only keeps one MAC example MAC1 adds a new entry from the FO/1 input MAC table for the first time (MAC1, F0/1) Later MAC1 enters from another interface F0/5 This time the MAC table does not add a new entry but updates (MAC1, F0/1) 에게 (MAC1, F0/5)
