If “Port Priority” is enabled and a high priority is assigned
to a physical port, all packets passing through this port
are mapped into high priority. As a result, the switch
processes the received/transmitted packets through this
port first.
If “802.1Q tag Priority” is enabled, the switch automati-
cally reads the 3-bit priority tag from the packet with a
VLAN tag. And if such a priority tag indicates a high
priority, this packet is mapped into high priority. In this
way, when the switch gets faulty, it will process packets
transmitted by this port first.
If “ToS Priority” is enabled, the switch automatically reads
the 8-bit ToS tag from the IPv6/IPv4 packet. And if such
a priority tag indicates a high priority, this packet is
mapped into high priority for priority processing.
