The core layer switch is a Layer 3 switch e nang le phallo e phahameng ka lebelo, bandwidth ea sebopeho se seholo (joalo ka sebopeho sa 10-gigabit), le bokhoni bo boholo ba ho sebetsa ka sefofane.Ka hona, ts'ebetso ea eona e phahame ho feta ea li-switches tsa lera la aggregation le li-switches tsa lera la phihlello.Li-switches tsa aggregation le tsona li na le mesebetsi ea ho tsamaisa 'me e ka ba li-switch tsa Layer 2 kapa Layer 3.Li-switches ke li-switches tsa Layer 2.Ka hona, li-switches tsa aggregation li na le ts'ebetso e phahameng, likou tse fokolang, le litefiso tse phahameng ho feta li-switches.Ka bokhutšoanyane, liphetho tsa papiso ea ts'ebetso ea li-switch tsena tse tharo ke: core layer switch> Aggregation layer switch> Access layer switch.
