QoS Global Settings Page
The QoS Global Settings page contains the following fields:
Quality of Service—Enables managing network traffic using QoS. The field value options are:
l
Enable—Enable QoS on the device.
¡
Disable—Disable QoS on the device.
¡
Trust Mode—Determines which packet fields to use for classifying packets entering the switch. When no rules are defined the traffic containing the
l
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.
