I'd like to understand a little more on the Ethernet switches.
Consider this Ethernet Switch which is a 3 port switch.
Like, it has 2 copper ports and one digital (MAC side interface) port.
It is mentioned as Gigabit ethernet switch port. In that case, when the 2 Cu ports have 1Gbps input data coming, (so total 2Gbps of data), will the output MAC port also be able to provide the data at 2Gbps or 1Gbps?
What is the purpose of a switch in case if it can provide only 1Gbps MAC data output when 2 Cu ports have 2Gbps input data but the MAC side or the switch can only transmit data at only 1Gbps speed?
I understood about the Non-blocking term from my previous question. But in this case, if the switch can provide only 1Gbps MAC output, does it really make any sense to say the switch is non blocking?
