Trust Mode
—Determines which packet fields to use for classifying packets entering
the switch. When no rules are defined the traffic containing the predefined packet
field (CoS, DSCP or TCP/UDP port) is mapped according to the relevant trust modes
table. Traffic not containing a predefined packet field is mapped to best effort. The
possible trust mode field values are:
–
CoS
—Indicates the output queue assignment is determined by the IEEE802.1p
VLAN priority tag (VPT) or by the default VPT assigned to a port.
–
DSCP
—Indicates the output queue assignment is determined by the DSCP field.
–
TCP/UDP
—Indicates the output queue is determined by the TCP/UDP port.
