Hi all, Got a very basic question, why physical link is flapped when we set the address # dmesg -c # ifconfig ix1 ether 70:6d:15:1f:12:72 ..wait.. # dmesg ix1: link state changed to DOWN ix1: link state changed to UP # is this a bug or expected behavior? We could update our MAC in next ARP request without link flap or some other system like switch etc expect the link flap to update ARP. Is this the behavior for other systems? Thanks in advance. -Anish
