Information About Interfaces
Virtual Ethernet Interfaces
Virtual Ethernet (vEthernet or vEth) interfaces are logical interfaces. Each vEthernet interface corresponds to a switch interface that is connected to a virtual port. The interface types are as follows:
VM (interfaces connected to VM NICs)
vEthernet interfaces are created on the Cisco Nexus 1000V to represent virtual ports in use on the distributed virtual switch.
You can use the management interface to connect the device to a network for remote management using a Telnet client, the Simple Network Management Protocol (SNMP), or other management agents.
Simplifying the Interface Configuration with Port Profiles
You can use a port profile to simplify the interface configuration. You can configure a port profile and then assign it to multiple interfaces to give them all the same configuration. Changes to the port profile are propagated to the configuration of any interface that is assigned to it.
We do not recommend that you override port profile configurations by making changes to the assigned interface configurations. You should make configuration changes to interfaces only to quickly test a change or to disable a port.
High Availability for Interfaces
Interfaces support stateful and stateless restarts. A stateful restart occurs during a supervisor switchover. After the switchover, the Cisco Nexus 1000V applies the run-time configuration.
