 All, we have several systems using IPMP and the MAC address comes from the
NIC since local-mac-address is set to true. We have some tracking software
that had the MAC address of the system prior to setting local-mac-address to
true.

Does anyone know how to get the original MAC address prior to setting the
local-mac-address variable? The hostid contains the last six digits but not
sure how to get the first six.
