Binding data plane interfaces to MAC addresses
Consider a scenario in which you are running a vRouter in a virtual machine (VM) and the virtual interfaces might not consistently appear at the same locations on each instantiation of the VM.
On the first boot of the VM, the interface assignments might be as follows:
| Data plane interface | MAC address |
|---|---|
| dp0s3 (physically in slot 3 on the VM) | 00:01:02:03:05:06 |
| dp0s4 (physically in slot 4 on the VM) | 00:01:02:03:05:07 |
To keep the NICs in slots 3 and 4 assigned to dp0s3 and dp0s4, respectively, for every subsequent instantiation of your VM, enter the following commands:
vyatta@R1# set interfaces dataplane dp0s3 hardware mac 00:01:02:03:05:06
vyatta@R1# set interfaces dataplane dp0s4 hardware mac 00:01:02:03:05:07
vyatta@R1# commit
vyatta@R1# saveYou do not have to reboot the vRouter.
