Capacity License

  • 1.  Capacity License

    Posted 30 days ago

    Hi

    As far as I checked for MX960 LCs and Chassis there is no Capacity license beside BNG license. So I assume If we want to use this router we just need feature licenses per card or per Chassis.

    Is this assumption correct?

    MX240/480/960 chassis have some licenses for capability and most are chassis based. There are also some RTU. cards you need to be aware of. Feature licenses are generally chassis based, so you are on the right track.

    Dear Brian

    Referring to:

    https://www.juniper.net/documentation/en_US/release-independent/licensing/topics/topic-map/software_licensing_requirements.html

    They are indeed Capacity licenses for MX series but they are applicable for MX5 or MX104. All I can see is BNG Licenses which for using MX as BRAS and feature like NAT,PCRF and JFlow. Is this link reliable?

    I also know that there is -IR and -R level for some cards(e.g. MPC7E Series) which provides access to Feature sets. (Also this is different with MPC10E and MPC15E)

    What I mean about capacity is How much traffic the router can handle. For example MX960 is supposed to handle 480Gbps per slot using SCBE2 and  1.5Tbps(Full Duplex-Line rate) per slot Using SCBE3-MX-BB and MPC15. Are these numbers licensed-based or just we are entitled to have these number as soon as card is purchased on was installed in the Chassis?

    Thank you

    Alireza 

    Thank you

    Hello Alireza,

    From capacity( throughput) perspective from Native Routing perspective the below Upgrade licences example you have

    - mx5-to-mx10-upgrade

    - mx10-to-mx40-upgrade

    - mx40-to-mx80-upgrade

    Or what is mentioned by "Upgrade license" in the below link

    https://www.juniper.net/documentation/en_US/release-independent/licensing/topics/topic-map/software_licensing_requirements.html

    Otherwise, you should consider other licences for MX series as Software/feature licences 

    And for accuracy when calculating the BW required is better to be based on PFE Capacity: for example, MPC7E has 2 PFEs 

    MPC7E has 2 PFEs  >> PFE Capacity = 240G >>MPC Capacity = 480G

    • Bandwidth per PFE is dependent on three factors
      • Memory bandwidth for packet reads and writes
      • The bandwidth to/from the fabric
      • The packets per second processing capacity
    • Packet read/write memory hard enforces the maximum bandwidth
    • Fabric capacity varies for the same PFE
      • Number of PFEs per line card
      • Speed and number of fabric links on the chassis
      • Fabric chip

    - For Example, MX960 has 6 planes located on 3 Fabric cards, 2 planes per fabric 

    - Fabric Midplane Bandwidth should be also taken into consideration 

    > In short: the usable bandwidth is MIN (Line card BW, Fabric Capacity, Midplane)

    > No license needed in case of your example mentioned with different  SCBx

    Regards,

    Bemwa Beshay

    Hi 

    Another question is When we say a card supports line rate, I assume if card has 10x100GE it can provide 100GE on each port full duplex, So the Fabric capacity must be 10x100GE or 1Tbps.

    Now if install 7x(10x100GE) I will have 1Tbps on each of 7 card" Full Duplex". Consider I use SCBE3-MX.

    Anyway based on Datasheet MX960 supports 12Tbps

    Is this correct?

    Thank you

     Hello,

    Your Understanding is right. 

    the link needed below 

    Licenses for PTX, MX, M and T Series

    SCBE3 support up to 1.5T per line card on MX960/MX480/MX240

    For MPC10E-10C-MRATE : 

    Throughput - 1Tbps

    2 PFEs per line card

    Each PFE throughput 500 Gbps

    800Gbps throughput with standard midplane

    1 Tbps throughput with enhanced midplane

    Supports 10 ports per card 5 ports per PFE

    For MPC10E-15C-MRATE

    Throughput - 1.5 Tbps
    3 PFEs per line card
    Each PFE throughput 500 Gbps
    800Gbps throughput with standard midplane
    1.5 Tbps throughput with enhanced midplane
    Supports 15 ports per card 5 ports per PFE

    Hi Bemwa

    Thank you for the answer, are these values in Full Duplex?

    I remember before Juniper used to mentioned the values in Half duplex.

    I assume line-rate simply means full duplex right?

    Thank you again
