Fex Qos Configuration Example - Cisco Nexus 9000 Series Configuration Manual

FEX QoS Configuration Example

• For IPv6 QoS TCAM carving support, you can use the hardware access-list tcam region fex-ipv6-qos
• For MAC based QoS TCAM carving support, you can use the hardware access-list tcam region
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.
class-map type qos match-all DSCP8
class-map type qos match-all DSCP16
class-map type qos match-all DSCP32

For configuring the uplink Layer 3 ports:
