In Virtual chassis on EX200 , each PFE is assigned a device ID . Is Device ID always equal to PFE ID?

Above we have two PFE : PFE0 and PFE1.

Above device ID 0 is assigned to PFE 0 because PFE is numbered as zero?
Thanks and have a good weekend!!
No, the device id also changes with the member ID. It is a value assigned to each PFE, within the Virtual Chassis for VCCP calculations.
The EX2200-48T/P is a dual-PFE so each switch/FPC or member (in a VC) will have two PFE's each. And each PFE is assigned a device ID as rightly mentioned in the previous post. Note that EX2200-24T/P is a single PFE so you may only find one device ID on those.
Hope this helps.

A useful command for this is:
>show virtual chassis vc port
show virtual-chassis vc-path source-interface ge-0/0/0 destination-interface ge-0/0/43
will give you this output (this can also be done across VC members):
vc-path from ge-0/0/0 to ge-0/0/43Hop Member PFE-Device Interface0 0 1 ge-0/0/01 0 2 internal-1/252 0 0 ge-0/0/43
As you can see here it is telling you
ge-0/0/0 is an interface from PFE-Dev 1
ge-0/0/43 is an interface from PFE-Dev 0
and PFE-Dev 2 is actually internal (internal-1/25 is actually part of the VC-ports)
you can experiment a little with that command I am sure you can see the information you need that way.
