been provided for usage of the DM8603’s three ports, and the internal memory supports an up to 1K uni-cast
MAC address table. Then to meet the demands of various bandwidth and latency issues in data, voice, and
video applications, each port of the DM8603 has four priority transmit queues. These queues can be defined
either through port-based operation, 802.1p VLAN, or the IP packet TOS field automatically.
