    Dear All


    What is the best methode to change VCP port for EX-4300 ?

    I want to switch it from 10 Gbps uplink port to 40 Gbps QSFP+ in rear panel.

    Should i break the VC and start build it again ?


    Thanks for sharing.

    You should be able to just provision the 40G ports, get link up and verify connectivity and then decommision your 10G VCP links.


    EX4300 supports dual-rings where eg. EX3400 is single-ring, where you had to remove a single 10G link at a time a reprovision as 40G.


    If I remember correctly, dual VCP links are not weighted so both 40G and 10G will receive same amount of traffic... but as you are going from 10G to 40G that's not a problem 🙂

    You can also view the below documentation for a better understanding of the VC ports configuration in EX4300:
