  • 1.  MPC7E-MRATE Port Speed

    Posted 08-19-2021 11:19
    Looking for clarification regarding port speed configuration for the MPC7E-MRATE  cards.  Documentation states cannot exceed 240g per pic.  I am looking to fully utilize all ports. I understand to do so I need to configure at the port level and not pic level.  If a port is configured at 10g does Junos look at the port as 10g or 40g being its really 4x10g?  In the config  below  would Junos look at pic 0 as 180g or 300g and pic 1 at 240g or 360g?  Would the config below commit succeed?    

    Thanks in advance!

    Configuring at the port level is the best way.
    But whatever you configure, you cannot commit an oversubscribed port configuration: you can provision 240G per PIC and nothing more.
    A «10G» port is 4x10G, and it counts for 40G.

    If you want two 100G ports on each «PIC», you have only one remaining usable port (40 or 4x10) per PIC.

    Thank you for the clarification.   This makes it easier to assign ports ports when the cards arrive.

    Much Appreciated!!

    greed every PIC must not exceed 240G and here are the possible combinations:

     

    Ports speed Combinations in PIC-mode:

    2*100G;

    6*40G;

    6*4*10G;

     

    Ports speed Combinations in port-speed mode:

    All combinations in PIC mode;

    N*40G + M*4*10G,  N+M ≤ 6;

    1*100G + N*40G + M*4*10G,  N+M ≤ 3;

    2*100G + 1*40G;

    2*100G + 1*4*10G.

     

    Please use port-speed only if necessary.

     

    Hope this helps.
