The MAC address table of a switch is as follows. If the switch receives a data frame whose destination MAC address is 5489-9885-18a8 from Eth0/0/2, which of the following statements is true?
The MAC address table of a switch is as follows. If the switch receives a data frame whose destination MAC address is 5489-9885-18a8 from Eth0/0/2, which of the following statements is true?
When a switch receives a frame with a destination MAC address that is already associated with the same port on which the frame arrived (Eth0/0/2 in this case), the switch discards the frame. This is because the switch considers it redundant to forward the frame back to the same port from which it originated.
There could be a case where a HUB is connected to eth0/0/2, and another endpoint device with a different source mac-address tries connectivity to a destination also connected to the same hub, in any case these another mac-address will be added to the switch in the same inteface but with another source mac-address, updating the mac table.
