PIM/PIC/FPC explanation..

Can someone breakdown the relationship between PIMs/PICs, and FPCs for me? I've worked with Cisco

devices for 10 years, but I'm brand new to Juniper. Haven't had much luck finding a good explation on this

topic. I nkow what the acronyms stand for, but now sure how they relate to one another.

 

Thanks,

 

Andy

Re: PIM/PIC/FPC explanation..

Super high level:

 

PIM - Physical Interface Model - found in J Series - adaptor card for I/F's - T1, ADSL, Ethernet......

PIC- Physical Interface Card - found in other JUNOS Routers - adaptor card for I/F's - T1, ADSL, Ethernet...... used in M series routers

FPC - Flexible PIC Concentrator - PICS go into FPC's on larger routers - - example 4 PIC's to an FPC - used in larger routers

 

If you send me your email address I can send you a nice PowerPoint that does a good job of explaining the hardware architectures in more detail.

Re: PIM/PIC/FPC explanation..

A quick note to put this in context -- The JUNOS interface naming convention = MM-F/P/T

 

      MM = media: fe (Fast Ethernet), ge (Gigabit Ethernet), se (Serial), t1 (T1 or DS-1), t3 (T3 or DS-3), so (SONET), etc.

      F = FPC (M/T/MX-Series) or PIM (J-Series) slot in the chassis

      P = PIC slot (M/T/MX-Series) in the FPC or 0 (J-Series does not use PICs)

      T = Port #

 

PIM -- J-Series Physical Interface Module that slides into a chassis slot

   The actual interface card (port adapter in Cisco-speak)

   Includes the "built-in slot 0 PIM" represented by the 10/100/1000 ports that come with the J-Series routers

 

FPC -- M/T/MX-Series Flexible PIC Controller that slides into a chassis slot

   The "carrier card" (or controller card in Cisco-speak) that allows you to slot interface cards

 

PIC -- M/T/MX-Series Physical Interface Card that slides into an FPC slot

   The actual interface card (port adapter in Cisco-speak)

 

Port # -- One of the physical ports on a PIM or PIC that can be used to carry traffic

 

 

Much of this information is from the "JUNOS as a Second Language" course and the book "JUNOS Enterprise Routing" amongst other sources.

Re: PIM/PIC/FPC explanation..

How does the interface naming convention vary when using DPC as opposed to FPC?

I think different chasses/models use different ways of counting FPC and PIC. Any reference for each model?

DPC uses the same convention as FPC, just that the 'PIC' part is fixed to the DPC.  When you look at "show chassis hardware" it will still list an FPC part and PIC part for the DPC to be consistent with other JUNOS boxes.

 

As far as counting the interfaces on the PIC, you have to look on the faceplate itself to see how they are numbered, as different PICs can arrange the ports in different ways.   The hardware guides generally show drawings to detail it.

 

Counting PICs on FPCs is consistent too, except that they could be horizontal or vertical.  In a vertical configuration, the top is zero and the bottom is 3 (except on M120 where there are 2 layers).  The horizontal configuration puts the zero PIC on the left and the 3 PIC on the right, as though you are taking the vertical one and rotating it counter-clockwise 90 degrees.

 

I hope that verbal description helps.
