Interface VLAN configurations are typically identical in Cisco NX-OS and Cisco Catalyst IOS Software. One 
difference is that in Cisco NX-OS, you must enable the interface-VLAN service, as follows: 

NXOS: (config)#feature interface-vlan 

NXOS: (config)#interface vlan <number> 

Hot Standby Router Protocol (HSRP) configurations are generally identical in Cisco NX-OS and Cisco Catalyst IOS 
Software. One difference is that in Cisco NX-OS, you must enable the HSRP service, as follows: 

NXOS: (config)#feature hsrp 

Additionally, the HSRP configuration under the interface is slightly different than it is in Cisco Catalyst IOS Software: 

NXOS: (config-if)# hsrp <group> 

NXOS: (config-if-hsrp)#ip <IP address> 

NXOS: (config-if-hsrp)#priority <priority> 

NXOS: (config-if-hsrp)#[no] preempt 

 

Catalyst IOS: (config-if)# standby <group> ip 

Catalyst IOS: (config-if)# standby <group> priority <number> 

Catalyst IOS: (config-if)# standby <group> preempt 

The show commands differ as follows: 

NXOS: #show hsrp brief 

Catalyst IOS: #show standby brief 

In Cisco NX-OS Software, the network command is not utilized; it has been replaced by the ip router ospf <area> 
command under the interface VLAN or the Layer 3 interface configuration, as follows: 

NXOS: (config)#feature ospf 

 

NXOS: config)# interface <VLAN> 

NXOS: config-if)#ip router ospf <area> 

Additionally, if you want to make an interface passive, enter the following: 

NXOS: config-if)# ip ospf passive-interface 

 

NXOS: router ospf 1 

NXOS: auto-cost reference-bandwidth 1000000 

Both Cisco Nexus and Cisco Catalyst platforms support the concept of virtual route forwarding (VRF). 

Cisco Nexus platforms utilize VRF by default for management purposes. Two VRFs are defined by default: 

● 

Default 

● 

Management
