Step Command
Remarks
3.
Apply the QoS policy to
the interface.
qos apply policy
policy-name
{
inbound
|
outbound
}
By default, no QoS policy is
applied to an interface.
You cannot apply a QoS
policy to the outbound
direction of a Layer 2
aggregate interface, Layer 3
aggregate interface, or VSI
interface.
Applying the QoS policy to VLANs
You can apply a QoS policy to VLANs to regulate traffic of the VLANs.
Configuration restrictions and guidelines
When you apply a QoS policy to VLANs, follow these restrictions and guidelines:
•
QoS policies cannot be applied to dynamic VLANs, including VLANs created by GVRP.
•
If the hardware resources of an IRF member device are insufficient, applying a QoS policy to
VLANs might fail on the IRF member device. The system does not automatically roll back the
QoS policy configuration already applied to other IRF member devices. To ensure consistency,
use the
undo qos vlan-policy vlan
command to manually remove the QoS policy
configuration applied to them.
Configuration procedure
To apply the QoS policy to VLANs:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Apply the QoS policy to
VLANs.
qos vlan-policy
policy-name vlan
vlan-id-list
{
inbound
|
outbound
}
By default, no QoS policy is applied
to a VLAN.
Applying the QoS policy globally
You can apply a QoS policy globally to the inbound or outbound direction of all ports.
If the hardware resources of an IRF member device are insufficient, applying a QoS policy globally
might fail on the IRF member device. The system does not automatically roll back the QoS policy
configuration already applied to other IRF member devices. To ensure consistency, use the
undo
qos apply policy global
command to manually remove the QoS policy configuration applied to
them.
To apply the QoS policy globally:
Step Command Remarks
1.
Enter system view.
system-view
N/A
2.
Apply the QoS policy
globally.
qos apply policy
policy-name
global
{
inbound
|
outbound
}
By default, no QoS policy is applied
globally.
Applying the QoS policy to a control plane
A device provides the data plane and the control plane.
