... PAUSE, backward congestion notification, and early-class watermark capabilities for congestion notification. These features in combination with its large buffer memory, allow the MB8AA3020 to handle both best-effort and guaranteed- high-availability customer traffic in a single chip. In addition to its standard 4K VLAN and Q-in-Q capabilities, the chip provides 64 additional user VLAN addresses, which can be used to logically partition a network without the use of Q-in-Q ...
