Configuring Layer 2 Interfaces
Beginning with Cisco Release 5.2, the Cisco Nexus 7000 Series devices support FabricPath Layer 2
Note
interfaces. See the Cisco Nexus 7000 Series NX-OS FabricPath Command Reference, Release 5.x for
complete information about the FabricPath feature and interfaces.
This chapter describes how to configure Layer 2 switching ports as access or trunk ports on Cisco
NX-OS devices.
Beginning with Cisco NX-OS Release 5.1, a Layer 2 port can function as either one of the following:
Note
A trunk port
•
An access port
•
A private VLAN port (see the Cisco DCNM Layer 2 Switching Configuration Guide, Release 5.x,
•
for more information on private VLANs)
A FabricPath port (see the Cisco Nexus 7000 Series NX-OS FabricPath Configuration Guide,
•
Release 5.x, and the Cisco DCNM FabricPath Configuration Guide, Release 5.x, for information on
FabricPath)
Beginning with Cisco NX-OS Release 5.2(1), a Layer 2 port can also function as a shared interface. You
cannot configure an access interface as a shared interface. See the Cisco NX-OS FCoE Configuration
Guide for Cisco Nexus 7000 and Cisco MDS 9500 for information on shared interfaces.
See the Cisco DCNM FabricPath Configuration Guide, Release 5.x, for more information on configuring
Note
the FabricPath feature.
A Layer 2 port can function as either a trunk port, an access port, or a private VLAN port.
