Applying The Qos Policy To An Interface; Applying The Qos Policy To A Vlan - HP FlexFabric 5700 series Configuration Manual

You can modify traffic classes, traffic behaviors, and class-behavior associations in a QoS policy even
after it is applied. If a traffic class uses an ACL for traffic classification, you can delete or modify the ACL
(such as add rules to, delete rules from, and modify rules of the ACL).
QoS policies applied to an interface, a VLAN, and globally are in descending order of priority. The
switch first matches the criteria in the QoS policy applied to an interface. If there is a match, the switch
executes the QoS policy applied to the interface and ignores the QoS policies applied to the VLAN and
globally.

Applying the QoS policy to an interface

You can apply QoS policies to the following interfaces:
Ethernet interfaces.
•
S-channel interfaces.
•
S-channel aggregate interfaces.
•
• VSI interfaces.
VSI aggregate interfaces.
•
For information about the preceding interfaces except Ethernet interfaces, see EVB Configuration Guide.
A QoS policy can be applied to multiple interfaces, but only one QoS policy can be applied in one
direction (inbound or outbound) of an interface.
The QoS policy applied to the outgoing traffic on an interface does not regulate local packets, which are
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.
To apply the QoS policy to an interface:
Step
1. Enter system view.
2. Enter Ethernet interface
view.
3. Apply the QoS policy to
the interface.
NOTE:
If both packet filtering with the permit statement and QoS policies are configured on an interface, the car
and filter actions in the QoS policies do not take effect. For information about packet filtering, see
"Configuring

Applying the QoS policy to a VLAN

You can apply a QoS policy to a VLAN to regulate traffic of the VLAN.
QoS policies cannot be applied to dynamic VLANs.
To apply the QoS policy to a VLAN:
Command
system-view
interface interface-type interface-number
qos apply policy policy-name { inbound |
outbound }
ACLs."

By default, no QoS policy
is applied to an interface.
