Applying the QoS policy
You can apply a QoS policy to the following destinations:
•
Interface
—The QoS policy takes effect on the traffic sent or received on the interface.
•
VLAN
—The QoS policy takes effect on the traffic sent or received on all ports in the VLAN.
•
Globally
—The QoS policy takes effect on the traffic sent or received on all ports.
•
Control plane
—The QoS policy takes effect on the traffic received on the control plane.
•
User profile
—The QoS policy takes effect on the traffic sent or received by the online users of
the user profile.
You can modify traffic classes, traffic behaviors, and class-behavior associations in a QoS policy
even after it is applied (except that it is applied to a user profile). If a traffic class uses an ACL for
traffic classification, you can delete or modify the ACL.
Applying the QoS policy to an interface
A QoS policy can be applied to multiple interfaces. However, only one QoS policy can be applied to
one direction (inbound or outbound) of an interface.
The QoS policy applied to the outgoing traffic on an interface does not regulate local packets. Local
packets refer to critical protocol packets sent by the local system for operation maintenance. The
most common local packets include link maintenance, routing, LDP, RSVP, and SSH packets.
QoS policies can be applied to Layer 2/Layer 3 Ethernet interfaces, Layer 3 Ethernet subinterfaces,
Layer 2/Layer 3 aggregate interfaces, and VSI interfaces.
For VSI interfaces, the QoS policy application feature is available in Release 2510P01 and later.
The term "interface" in this section collectively refers to these types of interfaces. You can use the
port link-mode
command to configure an Ethernet port as a Layer 2 or Layer 3 interface (see
Layer
2—LAN Switching Configuration Guide
).
On a border gateway in a VXLAN or EVPN network:
•
If a QoS policy without VLAN ID match criteria is applied to a Layer 3 Ethernet interface, the
QoS policy also takes effect on its subinterfaces.
•
If a QoS policy is applied to any other interface, the match criteria for untagged packets
forwarded at Layer 3 do not take effect if the following conditions exist:
{
A class contains an inner or outer VLAN ID match criterion.
{
The class also contains match criteria configured to match untagged packets forwarded at
Layer 3.
