Cisco ASA Series CLI Configuration Guide
1-16
Purpose
Configures the virtual MAC address for an interface.
The phy_if argument is the physical name of the interface, such as
Ethernet1. The active_mac and standby_mac arguments are MAC
addresses in H.H.H format, where H is a 16-bit hexadecimal digit. For
example, the MAC address 00-0C-F1-42-4C-DE would be entered as
000C.F142.4CDE.
The active_mac address is associated with the active IP address for the
interface, and the standby_mac is associated with the standby IP address
for the interface.
You can also set the MAC address using other commands or methods, but
we recommend using only one method. If you set the MAC address using
multiple methods, the MAC address used depends on many variables, and
might not be predictable.
Use the show interface command to display the MAC address used by an
interface.
