Question MAC Address spoofing on alias/secondary interface


Hi

I'm using Mandrake 10.2 (Mandriva). I have a machine with 2 NICs; the onboard and 2 additional ones. The 2 additional ones (eth1 and eth2) are bonded together as interface bond0. When bonded together the bond0 interface and eth1 and eth2 all have the same MAC address - as bonding is suppose to do (it takes the eth1 address and bond0 and eth 2 uses it too).

My question is: Is it possible for the 2 additional cards to have separate MAC addresses as it is causing problems at the switch as it thinks there is a loop as the MAC addresses are moving between ports. Or would bonding only work if the MAC addresses are the same?

I have read this:
whoozoo.co.uk/mac-spoof-linux.htm
and taken note of the extra bit at the end about not being able to spoof the mac address of a secondary or alias interface.


or does anyone else have any other solution that might solve this problem


thanks
Tara

Bonding requires that both interfaces share the same mac. Bonding also requires that your switch be capable of handling it.
