In order to configure a VRF in Cisco NX-OS Software, do the following: 

NXOS : (config)#vrf context <VRF NAME> 

NXOS : (config)#interface Ethernet1/1 

NXOS : (config-if)# vrf member <VRF NAME> 

In order to configure a VRF in Cisco Catalyst IOS Software, do the following: 

Catalyst IOS : (config)#ip vrf <VRF NAME> 

Catalyst IOS : (config)#interface Ethernet1/1 

Catalyst IOS : (config-if)# ip vrf forwarding <VRF NAME> 

Cisco NX-OS platforms offer a management interface. This port is clearly indicated on the front plate of Cisco Nexus 
devices and is configured through the following command: 

NXOS: (config)#interface mgmt0 

NXOS: (config-if)# ip address … 

Routing for management traffic is configured starting from the management vrf: 

NXOS: (config)#vrf context management 

NXOS: (config-if)# ip route … 

The Cisco Nexus switches follow the Cisco Modular Quality of Service command-line interface (MQC).  Quality-of-
service (QoS) features and capabilities are hardware-specific, and as a result, several options are specific to each of 
the Cisco Nexus platforms. 

MQC consists of three configuration steps: 

1.  Define match criteria with a class map. 

2.  Associate an action for each defined class with a policy map. 

3.  Apply the policy to the entire system or to an interface service policy. 

Classification 

A simple configuration example of classification is: 

Ip access-list ACL-A 

  Permit ip any 1.1.1.0/24 

 

class-map type qos qosgroupA 

  match access-group ACL-A 

 

policy-type qos policy-classify 

  class type qos qosgroupA 

    set qos-group 3 

  class type qos qosgroupB 

    set qos-group 4
