You can configure Layer 2 switching ports as access or trunk ports. Trunks carry the traffic of multiple
VLANs over a single link and allow you to extend VLANs across an entire network. All Layer 2
switching ports maintain media access control (MAC) address tables.
Note See the Cisco Nexus 7000 Series NX-OS Layer 2 Switching Configuration Guide, Release 5.x, for
information on VLANs, MAC address tables, private VLANs, and the Spanning Tree Protocol.
Note A Layer 2 port can function as either a trunk port, an access port, or a private VLAN port. See the Cisco
Nexus 7000 Series NX-OS Layer 2 Switching Configuration Guide, Release 5.x, for more information on
private VLANs.
