hi everyone
i created new virtual machines (centos6) on vmware esx5 but i have problem in a specific vlan (20). when i want to start or restart an interface it shows me "Error, some other host already uses address x.x.x.x".
i thought it is related to OS version but when i tested another os version (like red hat 5 , centos5) it showed the same error. however when i change vlan number it will be correct but when i return to vlan20 it has the same problem. i dont know why but this error only happened in Linux and when i change a windows vm to vlan20 it will work correctly. thanks in advance
