Configuring QoS
Beginning with Cisco NX-OS Release 5.0(2)N1(1), on the Cisco Nexus 5548 switch, you can configure
Note
qos policy and untagged cos on the same interface.
On the Cisco Nexus 5010 switch and the Cisco Nexus 5020 switch, untagged CoS and type QoS input
policies are mutually exclusive on an Ethernet or EtherChannel interface. If a type qos policy is configured
at the interface, untagged frames received over that interface will not match any match cos 0 commands
in the policy.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# interface {ethernet [chassis/]slot/port | port-channel channel-number}
3. switch(config-if)# untagged cos cos-value

Configuring Interface Service Policy
An input qos policy is a service policy applied to incoming traffic on an Ethernet interface for classification.
For type queuing, the output policy is applied to all outgoing traffic that matches the specified class. When
you configure an input queuing policy on an interface or EtherChannel, the switch sends the configuration
data to the adapter using the DCBX protocol.
Type qos policies can be activated only on Cisco Nexus 5000 Series interfaces and Cisco Nexus 2000
Note
Series Fabric Extender interfaces. Type qos policies on Fabric Extender fabric interfaces or Fabric Extender
fabric EtherChannel interfaces are ineffective, though the Cisco NX-OS CLI does not reject the
configuration.
We recommend that you do not configure type qos policy-maps on Fabric Extender fabric interfaces or
Fabric Extender fabric EtherChannel interfaces to avoid wasting hardware resources.
