Gents,

I will describe the way I understand this as I think there is still
something missing.

Failover mac-address is used to assign static MAC addresses to the failover
pair of devices. This is useful when both devices boot up and the Secondary
device will start first. As the active MAC address by default is derived
from Primary device, there can be a problem if the Secondary device boots
first. Then the Secondary device will use its own burned-in MAC address.

The "failover mac-address" is valid for Active/Standby failover only. For
Active/Active there is "mac address" command under the failover group.

"mac-address auto" command is used to automatically generate all MAC
addresses inside the security contexts. This is important if two contexts
share the same physical/logical interface. We use it in multi context mode
only.
Note that there is no need for that command when A/A failover is configured.

The traffic classifier is used to direct the traffic to the correct context.
It uses the following logic:
- different physical interfaces
- MAC addresses on the interfaces
- Global IP due to NAT/PAT.

HTH,
Piotr Matusiak
