Trunk Ports

A trunk port carries traffic for two or more VLANs. This port type is a Layer 2 interface only.

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)

• Service console

• vmkernel

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 Ethernet 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.

A port channel is a logical interface that aggregates multiple physical interfaces. You can bundle up to eight

individual links to physical ports into a port channel to improve bandwidth and redundancy. You can also use

port channeling to load balance traffic across these channeled physical interfaces.

You can offload operation of the Line Aggregation Control Protocol (LACP) from the VSM to the VEMs to

prevent a situation where LACP cannot be negotiated with the upstream switch when the VEM is disconnected

from the VSM (referred to as headless mode). VEM management of LACP allows port channels to be

reestablished after the reboot of a headless VEM.

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.
