Command History
Usage Guidelines Before you use a virtual Ethernet interface, you must enable the Cisco Virtual Machine Fabric Extender
(VM-FEX) on the switch by using the feature vmfex command.
You must configure a virtual Ethernet interface on each switch. The configuration in the secondary
switch must be identical to that of the primary switch.
You can create a maximum of 1000 virtual Ethernet interfaces on a Cisco Nexus 5548 switch. Before
you disable Adapter-FEX on the switch, make sure that you delete these interfaces. After you delete a
virtual Ethernet interface, make sure that you save the running configuration of the switch to the startup
configuration file.
Examples This example shows how to enter configuration mode for virtual Ethernet interface 10:
switch# configure terminal
switch(config)# interface vethernet 10
switch(config-if)#
This example shows how to enter configuration mode for multiple virtual Ethernet interfaces:
switch# configure terminal
switch(config)# interface vethernet 10, vethernet 2
switch(config-if-range)#
This example shows how to bind an interface, configure a vEthernet access interface, assign the access
VLAN for that interface, and then assign a port profile named ppVEth, and a class of service (CoS) value
3 to a virtual Ethernet interface:
veth-id Virtual Ethernet interface number. The range is from 1 to 1,048,575.
You can specify more than one virtual Ethernet interface. Make sure you use
the comma (,) separator.
