Configuring Cisco Nexus 5000 Series NX-OS Adapter-FEX
software
The Cisco NX-OS Adapter-FEX feature combines the advantages of the FEX link architecture with server
I/O virtualization to create multiple virtual interfaces over a single Ethernet interface. This allows you to
deploy a dual-port NIC on the server and to configure more than two virtual interfaces that the server
sees as a regular Ethernet interface. TTis approach allows you to reduce power and cooling needs and to
reduce the number of network ports.
About this task
Adapter-FEX can be thought of as a way to divide a single physical link into multiple virtual links or
channels. Each channel is identified by a unique channel number, and its scope is limited to the physical
link. The physical link connects a port on a server network adapter with an Ethernet port on the switch.
This allows the channel to connect a vNIC on the server with a vEthernet interface on the switch. Packets
on each channel are tagged with a VNTag that has a specific source virtual interface identifier (VIF). The
VIF allows the receiver to identify the channel that the source used to transmit the packet.
For more information about the Adapter-FEX feature, see the
Cisco Nexus 5000 Series NX-OS Adapter-
FEX Software Configuration Guide
.
Procedure
1
Enable the Adapter-FEX feature on each of the switches to which the server is connecting.
a
switch# configure terminal
b
switch(config)# install feature-set virtualization
c
switch(config)# feature-set virtualization
d
(Optional) switch(config)# vethernet auto-create
2
Configure the switch by creating a port profile to support Adapter-FEX.
a
switch# port-profile type vethernet port-profile_name
b
switch# switchport mode trunk
c
switch# switchport trunk allowed vlan 5,6,8-10
d
switch# state enabled
e
switch# configure terminal
f
switch(config)# interface Ethernet1/
5
g
switch(config-if)# switchport mode vntag
