•
Trust State—The trust state of an interface determines how it marks, schedules, and classifies
received L2 frames, and whether or not congestion avoidance is implemented. This attribute can
have the following values:
–
untrusted—The interface is marked as untrusted.
–
DSCP—The DSCP value of the frame is trusted.
–
CoS—The CoS value of the frame is trusted.
–
IP-precedence—The IP-precedence value of the frame is trusted.
•
Default CoS Value—Interface class of service value. QoS assigns the CoS value to untagged frames
from a trusted interface and to all frames of an untrusted interface.
•
Input Service Policy—The QoS policy map applied to the interface. This policy map is only applied
if QoS is enabled on the interface and VLAN-based QoS is disabled on the interface.
•
Queue Type (RX)—Describes the queue structure for traffic on an egress port.
•
Queue Type (TX)—Describes the queue structure for traffic on an ingress port.
•
Select Policy—Launches the Ethernet Interface Management - Modify QoS Policy Map window to
attach an input QoS policy map to the interface. This action may fail if the specified policy map is
not suitable for use with an Ethernet interface.
