Yes those four points are all very valid.
Just wanted to clear up that using 100G didn’t “lose” the extra 40G of capacity.

Hi Tobias,
Clearly our last beer together happened too long ago ;-)
I haven’t referred to the kb article or anything … I just wanted to mention
that you can use 100G and 40G ports on the same pic
as long as you don’t go above 240G per pic. Of course setting $whatever to 100G
only will not work.
Still… All of my points are valid.

Brian,
I'm not sure who you team is, but the other guys are correct. You can
provision the addition ports using port mode.
Just enabling the 100G ports does not disable the use of the additional 40G.
Been there done that, fully supported.

First, I would like to clarify that yes you can provision up to 240G of
capacity per PFE/PIC on the MPC7.
It can be any combination of 100/40/10, just as long as the total doesn't go
over 240, noting that only certain ports are 100G capable.
Second, to Tobias' comments,
Several points.
1. Configuration examples explaining how something is configured are not
supposed to imply that this is how you should configure it or even that the
exact configuration is valid. The example configuration could allow for
over-subscription if port 5 were added at 100G.
2. The

With 2x100G ports enabled you can still set one remaining port to 40G on the

And it also works just fine.
Which part of my last mail is not true? Maybe i did not make
Hi there,
That’s not true and you sad it yourself. You have 240G per PIC.
With 2x100G ports enabled you can still set one remaining port to 40G on the

Yes. But the speed must

Yes. But you can have 8 x 10G in addition in the form of 2 x 40G with
breakout. This is from one
FYI this is a more complex question….
From my understanding, you need to look at the card as 4 groups of 3 ports (2
QSFP+ and 1 QSFP28). Here are your options:
1. All 3 ports can be used at 40G or 4x10G in any combination. So 120G per
group or 480G per card. This is the maximum for the card.
Many thanks Charlie. It seems that calculation doesn't belong to my main
skills ;-)
Please forgot my questions...

If you are absolutely certain you are not providing DHCP you could always set
the punt rate to 1 and disable logging.
Beware, this can be an awfully sharp sword. Ask me how I know!

Hi,
we have some MX-Routers (MX480 and MX960) with MPC7E-MRATE linecards. As
far as i know, one PFE supports 240G each. Is it possible to use both
100G ports and in addititon 14x 10G ports on a single PFE ?
With the following configuration, i got an error "FPC 5 PIC 1 Invalid
