Juniper switch interfaces ifindex value

Juniper switch interfaces ifindex value

Hi,
I have a problem about identifying the interface names of Juniper 5200 switch on NFA 9.
When I check the switch config, it says ge-0/0.0 ge-0/1.0 etc. but their ifindex values are 522, 512, 312 etc. 
So how can I know which interfaces these values belong to? Do I have to check it from the switch console?
