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>
Management Port
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:
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 …
Quality of Service
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.
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
