#REMOVE NATIVE ACCESS MAC#

Trunks carry the traffic of multiple VLANs over a single link and allow you to extend VLANs across an entire network. Note An Ethernet interface can function as either an access port or a trunk port it cannot function as both port types simultaneously.Ī trunk is a point-to-point link between the device and another networking device.

#REMOVE NATIVE ACCESS MAC#

If an access port receives a packet with an 802.1Q tag in the header other than the access VLAN value, that port drops the packet without learning its MAC source address. Note Only an end station can be set as a host port you will receive an error message if you attempt to configure other ports as hosts. Use the host designation to decrease the time it takes the designated port to begin to forward packets. Once the port is configured as a host port, it is automatically set as an access port, and channel grouping is disabled. To optimize the performance on access ports, you can configure the port as a host port. In order to correctly deliver the traffic on a trunk port with several VLANs, the device uses the IEEE 802.1Q encapsulation or tagging method (see the “Understanding IEEE 802.1Q Encapsulation” section for more information on this subject). The trunk port carries traffic for two or more VLANs.įigure 1-1 Devices in a Trunking Environment A trunk port can have two or more VLANs configured on the interface it can carry traffic for several VLANs simultaneously.įigure 1-1 show how you can use trunk ports in the network.An access port can have only one VLAN configured on the interface it can carry traffic for only one VLAN.Understanding Access and Trunk InterfacesĮthernet interfaces can be configured either as access ports or a trunk ports, as follows: Note Cisco NX-OS supports only IEEE 802.1Q-type VLAN trunk encapsulation.
