The CoS Page contains the following:

•Quality of Service — Determines whether QoS is enabled on the interface. The possible values are:

–Enable — Enables QoS on the interface.

–Disable — Disables QoS on the interface.

•Trust Mode — Defines which packet fields to use for classifying packets entering the device. When no rules are defined, the traffic containing the predefined packet CoS field 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 — Classifies traffic based on the CoS tag value.

–DSCP — Classifies traffic based on the DSCP tag value.

•Copy from Entry Number— Indicates the row number from which CoS parameters are copied.

•to Entry Number(s)— Indicates the row number to which CoS parameters are copied.

•Interface — Displays the interface for which the global QoS parameters are defined.

–Port — Selects the port for which the global QoS parameters are defined.

–LAG — Selects the LAG for which the global QoS parameters are defined.

•Default CoS for Incoming Traffic— Determines the default CoS value for incoming packets for which a VLAN tag is not defined. The possible field values are 0-7. The default CoS is 0.
