QoS for L3Outs
To configure QoS policies for an L3Out, use the following guidelines:
-
To configure the QoS policy to be enforced on the border leaf where the L3Out is located, the VRF instance must be in egress mode (Policy Control Enforcement Direction must be "Egress").
-
To enable the QoS policy to be enforced, the VRF Policy Control Enforcement Preference must be "Enforced."
-
When configuring the contract governing communication between the L3Out and other EPGs, include the QoS class or target DSCP in the contract or subject.
Note
Only configure a QoS class or target DSCP in the contract, not in the external EPG (
l3extInstP
).
-
When creating a contract subject, you must choose a QoS priority level. You cannot choose Unspecified.
Configuring QoS for L3Outs Using the NX-OS Style CLI
QoS for L3Out is configured as part of the L3Out configuration.
Procedure
Step 1 |
When configuring the tenant and VRF, to support QoS priority enforcement on the L3Out, configure the VRF for egress mode and enable policy enforcement, using the following commands: Example:

Configuring QoS Directly on L3Out Using CLI
This section describes how to configure QoS directly on an L3Out. This is the preferred way of configuring L3Out QoS starting with Cisco APIC Release 4.0(1).
You can configure QoS for L3Out on one of the following objects:
-
Switch Virtual Interface (SVI)
-
Sub Interface
-
Routed Outside
Procedure
Step 1 |
Configure QoS priorities for a L3Out SVI. Example:

Step 2 |
Configure QoS priorities for a sub-interface. Example:
|
Step 3 |
Configure QoS priorities for a routed outside. Example:
