Information About Port Channels
Figure 6-1 Port-Channel Interfaces
You can classify port-channel interfaces as Layer 2 or Layer 3 interfaces. In addition, you can configure
Layer 2 port channels in either access or trunk mode. Layer 3 port-channel interfaces have routed ports
as channel members and may have subinterfaces.
Beginning with Cisco NX-OS Release 4.2(1), you can configure a Layer 3 port channel with a static
MAC address. If you do not configure this value, the Layer 3 port channel uses the router MAC of the
first channel member to come up. See the Cisco Nexus 7000 Series NX-OS Layer 2 Switching
Configuration Guide, Release 5.x, for information on configuring static MAC addresses on Layer 3 port
channels.
See Chapter 3, “Configuring Layer 2 Interfaces,” for information on configuring Layer 2 ports in access
or trunk mode and Chapter 4, “Configuring Layer 3 Interfaces,” for information on configuring Layer 3
interfaces and subinterfaces.
