Note	FEX QoS is not supported on the Cisco Nexus 9508 switch (NX-OS 7.0(3)F3(3).

Note	Only 4Q queuing policy model is supported on FEX. When you try to bring up FEX in 8Q queuing policy mode you will get an error message.

You must free up unused TCAM space to accommodate TCAM carving for FEX QoS.

Note	FEX QoS is not supported on the Cisco Nexus 9508 switch (NX-OS 7.0(3)F3(3).

• For FEX QoS TCAM carving for IPv4 traffic, you can use the hardware access-list tcam region fex-qos 256 command.

  As a best practice, you can use the hardware access-list tcam region fex-qos-lite 256 command when policers are not used.

  Note	The fex-qos-lite region does not have conformed policer statistics support for IPv4.

• For IPv6 QoS TCAM carving support, you can use the hardware access-list tcam region fex-ipv6-qos 256 command.

• For MAC based QoS TCAM carving support, you can use the hardware access-list tcam region fex-mac-qos 256 command.

• When configuring end to end queuing from the HIF to the front panel port, the QoS classification policy 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:

  
  system qos
    service-policy type qos input LAN-QOS-FEX
  
  interface Ethernet101/1/12
    service-policy type qos input LAN-QOS-FEX
  

class-map type qos match-all DSCP8
       match dscp 8
class-map type qos match-all DSCP16
       match dscp 16
class-map type qos match-all DSCP32
       match dscp 32
policy-map type qos-remark
      class  DSCP8
           set qos-group 1
           set cos 0
      class  DSCP16
           set qos-group 2
           set cos 1
      class  DSCP32
           set qos-group 3
           set cos 3
     class  class-default

Int ethx/y
     Service-policy type qos input qos-remark

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.

Input queuing (system type queuing input policy)

Note	System input queuing is applied on NIF Ports for HIF to NIF traffic.
