Configuring a Static MAC Address on a Layer 3 Interface

Beginning with Release 4.2(1), you can configure static MAC addresses on Layer 3 interfaces. You cannot
configure broadcast addresses as static MAC addresses. Beginning with Cisco NX-OS Release 5.2(1), multicast
MAC addresses can be configured as static MAC addresses. For further information, see the "Configuring
IGMP Snooping" of the Cisco Nexus 7000 Series NX-OS Multicast Routing Configuration Guide.
You cannot configure static MAC addresses on tunnel interfaces.
Note
See the Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide for information on configuring Layer
3 interfaces.
Before You Begin
Before you configure static MAC addresses, ensure that you are in the correct VDC (or enter the switchto
vdc command).
