Ex3300 Virtual Chassis preprovisioning issue.

Hi Guys,

 

I have an interesting issue. I have a 2 member VC where I am using preprovisioning. However that info seems to be getting ignored by the switches upon reboot. Even if I stagger the reboots the wrong switch becomes master. In my preprovision config I have the higher serial numbered switch set as member 0 and routing-engine role assigned. Upon reboot of all the switches member 1 always becomes master. Even if I let member 0 boot first it will stay as a Line card until the other is booted. It will not assume its role as a routing engine until the other node comes up and then it assumes the backup role.  It also doesnt route traffic. I have to manually trigger a role release for member 0 to assume the Master routing role. After that everything works and connectivity is restored. Anyone seen this kind of behavior?  Pasted my VC config below. 

 

preprovisioned;
no-split-detection;
member 0 {
role routing-engine;
serial-number GA02170704XX;
}
member 1 {
role routing-engine;
serial-number GA02170701XX
