Hi I agree with the last reply,
vme you can only have one, you could configure 2 me0 interfaces one for the master and one for the backup as explained here:

vme stands for virtual management ethernet, it is basically a virtual interface that you can reach through any of the members of a VC. I personally think this is more efficient than configuring different IPs for the different members once on the master you ca use:
>request session member <member id>
to move between the different members of the VC.
