For example , if a multilayer switch supports ip , then ipx packets can only be switched at layer 2 not routed at layer 3 例如,若某臺多層交換機支持ip協(xié)議, ipx包則只能在第二層上交換,不能在第三層上規(guī)定路由。
A multilayer switch (MLS) is a computer networking device that switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers.
