This command was introduced. |
Usage Guidelines
In-order delivery of data frames guarantees frame delivery to a destination in the same order that they were sent by the originator.
Examples
This example shows how to enable in-order delivery for the entire switch:
switch(config) # in-order-guarantee
This example shows how to disable in-order delivery for the entire switch:
switch(config)# no in-order-guarantee
This example shows how to enable in-order delivery for a specific VSAN:
switch(config)# in-order-guarantee vsan 3452
This example shows how to disable in-order delivery for a specific VSAN:
switch(config)# no in-order-guarantee vsan 101

Usage Guidelines
Note 
The Cisco virtual machine feature is supported only on the Cisco Nexus 5500 Series switches.
This command requires an Enhanced Layer 2 license.
Examples
This example shows how to install the Cisco virtual machine feature set on the switch:
switch# configure terminal
switch(config)# install feature-set virtualization
switch(config)#

interface fc
To configure a Fibre Channel interface on a Cisco Nexus 5000 Series switch, use the interface fc command. To revert to defaults, use the no form of this command.
interface fc slot/port
channel-group {group-id [force] | auto}
fcdomain rcf-reject vsan vsan-id
fcsp {auto-active | auto-passive | on | off} [timeout-period]

4.0(0)N1(1a) |
This command was introduced. |
Usage Guidelines
You can specify a range of interfaces by entering a command with the following example format:
interface fc 1/1 - 5 , fc 2/5 - 7
Use the no shutdown command to enable the interface.
The interface fc command enters interface configuration mode, which includes five commands (each with a no form). These five commands can only be used in the interface configuration mode.
The channel-group auto command enables autocreation of port channels. If autocreation of port channels is enabled for an interface, you must first disable this configuration before downgrading to earlier software versions or before configuring the interface in a manually configured channel group.
Examples
This example shows how to configure ports 1 to 4 in Fibre Channel interface 3:
switch(config)# interface fc 3/1 - 4
This example shows how to enable the Fibre Channel interface in port 1 of slot 3:
switch(config)# interface fc 3/1
switch(config-if)# no shutdown

interface vethernet veth-id[, vethernet veth-id, ...]
no interface vethernet veth-id[, vethernet veth-id, ...]
Syntax Description

5.1(3)N1(1) |
This command was introduced. |
Usage Guidelines
Before you use a virtual Ethernet interface, you must enable Cisco virtual machine feature on the switch by using the feature-set virtualization command.
You can create a maximum of 1000 virtual Ethernet interfaces on a Cisco Nexus 5548 switch. Before you disable the Cisco Adapter Fabric Extender (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 remove a virtual Ethernet interface:
switch# configure terminal
switch(config)# no interface vethernet 2
switch(config)#
