... GMAC ARL TA BLES 4 CoS QUEUES 10/100/1000 GMAC The BCM5682 supports IEEE 802.1p with up to four Class of Service (CoS) queues per egress port, along with traffic class expediting and dynamic multicast filtering. The chip implements a number of advanced mechanisms for flow control. Two mechanisms, cell-based HOL blocking and packet-based HOL blocking, to prevent Head Of Line blocking on a per-port basis. A packet aging mechanism discards packets residing in the switch’ ...
