    What license is require to configure EVPN and VXLAN features on QFX 5120-48Y switches.


    In License Guide document the two types of licenses are mentioned,

    1) S-QFX5K-C1-A2 mentioned under the Flex Software Subscription Model and

    2) QFX5K-C1-PFL. mentioned undet the Software Licenses.

    What is the difference in between these two licenses and which of them require to configure EVPN/VXLAN features on QFX 5120-48Y.

    Hello Arslan,


    QFX5120-48Y supports old perpetual as well as subscription (Flex) licenses.



    For EVPN-VXLAN, you need the Premium Feature set, which is the middle one. Advanced would be the highest one for this old perpetual feature license.

    So actually "QFX5K-C1-PFL" is the perpetual license without any service contract, just the features.



    For the Flex license, Juniper made it funny as here the Advanced license is the middle one and the Premium the highest one (in contrary to the old perpetual feature license). Here you have 3 possibilites:


    S-QFX5K-C1-A2-3 - Advanced 2 Feature set including Service Contract for 3 years
    S-QFX5K-C1-A2-5 - Advanced 2 Feature set including Service Contract for 5 years
    S-QFX5K-C1-A2-P - As well perpetual, but I have absolutely no idea what the difference is between the old "QFX5K-C1-PFL" and this one

    Hi all, 

    In the same mean regarding the QFX Licensing, is the "S-QFX5K-C1-A2-3" include all features of "S-QFX5K-C1-A1-3" ? 

    I think so but I want confirmation please. 


    Thx in advance,

    Yes, A2 includes all features of A1 as shown on in figure 12 on the following link.




    Compared to previous license type from Juniper, you don't need to stack licenses - the higher tier includes the features of the lower one.

    @F1ght3r: I need to correct you a bit.


    QFX5120-48Y can currently be purchased in two variances: "legacy" and "flex" with different list prices.


    QFX5120-48Y-AFO is the legacy SKU

    QFX5120-48Y-AFO2 is the flex SKU


    The flex SKU is lower priced but also comes with fewer base features. We have been used to having virtual chassis, OSPF, routing-instances and similar included in the base SKU. That is not the case with the flex model anymore... but as mentioned, the hardware list prices has been lowered accordingly.


    If you buy a legacy HW SKU, you should buy the QFX5K-C1-PFL license + support

    If you buy a flex HW SKU, you should buy either the 3 or 5 year subscription SKU *or* the perpetual flex SKU (S-QFX5K-C1-A2-P) + support.


    Overall the Flex A2 subscription matches the features of the legacy PFL license.

    Flex P1 matches legacy AFL license.


    Bonus note: the legacy licenses and the perpetual flex license are non-portable where the subscriptions can be migrated between devices.


    I hope this clarifies a bit 🙂

    One other point for Flex Licenses.  Currently there are no upgrade SKUs for A1 to A2/P or A2 to P, so best to purchase the license level you might need for the future, day 1.


    Yes some compensation on next sale for all is possible (probable) but this just makes things harder for all involved on $$ side.


    Just FYI
