OMAPI Host Object and Duplicate MACs in different subnets

[Caciano Machado]

Glenn,

It's not exactly what I need.

My problem is: different machines which have the same MAC address but
are in different subnets. They may have different configurations.

Anyway, I tried to create a host entry with the parameter
fixed-address using more than one IP, but it's not possible. OMAPI
takes only the first argument.

Any ideas?

Thanks,
Caciano Machado
