You won't see these MAC in any commands as this is used internally
to the VSX cluster (and ISL).
However, on the same L2 domain and if you configure STP, you should avoid having contiguous system-MAC: i.e 02:02:00:00:01:00 and
02:02:00:00:01:01 will collide due to the -1/+1 rule. So please make sure that in your system-MAC allocation you have +3 between them,
assuming these devices share L2 domain and use STP.
