  • 1.  Best performance / bandwidth using VSF?

    Posted Feb 21, 2024 03:05 PM

    Hi, 

    I am currently configuring two 6300m for a stack but I am not sure about the best practice in that case. How do I have to set VSF if I want to use two DAC cables with the maximum bandwidth of 20G? Do I have to set one VSF link and add all ports to it? Or do I have to set 2 VSF links each with two interfaces?

    I already saw some screenshots that are showing the used bandwidth on VSF but I guess those commands are not available on a 6300m.

    Thanks for your help!

    You should keep 2 separate links for redundancy. the speed will be determined by the DACs used for the connection (SFP+ 10gb, SFP28 25gb or SFP56 50gb).

    So if you want a max bandwidth of 20gb, you would buy the SFP+ 10gb DAC cables (I believe the 1m part number is J9281B)

    hi,

    Various 6300M might have various ports capability, look for your specific model and go as high as you can. 

    and look in the manuals Transceiver Guide. Follow best practices.

    Look for new model S0E91A,, supporting "Up to 400 Gbps stacking bandwidth"

    (HPE Aruba CX 6300 new addition S0E91A & S0X44A! | Wired Intelligent Edge (arubanetworks.com))

    be aware:

    "50G capability is for use with 50G DACs for both interconnect and VSF stacking. 50G transceivers and DACs are not supported on S0E91A and S0X44A switch models, which requires QSFP to SFP56 DAC cable for VSF stacking with other CX 6300 switch models. VSF stacking not supported on 1G ports"

    happy stacking
