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. Basic Settings You can configure the following basic settings for the port-channel interface • Bandwidth-Use this setting for informational purposes only; this setting is to be used by higher-level protocols. • Delay-Use this setting for informational purposes only; this setting is to be used by higher-level protocols. • Description • Duplex • Flow control. • IP addresses-Both IPv4 and IPv6 • Maximum Transmission Unit (MTU) Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide, Release 5.x 6-4 OL-23435-03
