FEX QoS Configuration Example

• When configuring end to end queuing from the HIF to the front panel port, the QoS classification policy
Example of a FEX QoS Marking Policy Configuration
The following example is to configure set cos when the incoming traffic is untagged on the Layer 3 uplink
port with DSCP values. In this way, it carries cos values to the FEX ports when traffic comes on the Layer 3
port and egress out on the FEX HIF port.

FEX QoS Configuration Example
Note
FEX QoS is not supported on the Cisco Nexus 9508 switch (NX-OS 7.0(3)F3(3).
The following are examples of the aspects of a FEX QoS configuration.
Classification (system type qos policy)
Policies of type qos are applied to classify incoming packets.
• Class map configuration:

needs to be applied to both system and HIF. This allows the FEX to queue on ingress appropriately
(system) and allows the egress front panel port to queue appropriately (HIF).
Example:

match dscp 16
match dscp 32
