802. 1 p trusted mode or DSCP trusted mode.
To configure the QoS settings per interface:
Click Quality of Service > QoS Basic Mode > Interface Settings.
Select a port or LAG and click Go.
The QoS State column displays whether QoS is enabled on the port or LAG.
To enable or disable QoS on an interface, select the interface and click Edit.

•
QoS State—Check Enable to enable QoS on this interface, or uncheck to

Click Apply. The Running Configuration is updated.
Frames that match an ACL and were permitted entrance are implicitly labeled with
the name of the ACL that permitted their entrance. QoS advanced mode actions
can then be applied to these flows.
In QoS advanced mode, the switch uses policies to support per flow QoS. A policy
and its components have the following characteristics and relationships:
•
A policy contains one or more class maps.
•
A class map defines a flow with one or more associating ACLs. Packets that
match only ACL rules (ACE) in a class map with Permit (forward) action are
considered belonging to the same flow, and are subjected to the same
quality of services. Thus, a policy contains one or more flows, each with a
user defined QoS.
•
The QoS of a class map (flow) is enforced by the associating policer. There
are two type of policers, single policer and aggregate policer. Each policer
is configured with a QoS specification. A single policer applies the QoS to a
