    Hi,

     

    could someone tell me why two VSF stack in the same networ must have different domain ID?

     

    Than you

    Because VSF, as chassis virtualization technology, uses the VSF Domain Ids to uniquely identify VSF Fabrics and prevent VSF Fabrics from interfering with one another (that is exactly what is needed when you're going to deal with two VSF Fabrics on the verys same network). One VSF Fabric forms one VSF Domain...so one VSF fabric is uniquely identified by its VSF Domain Id.

    Greetings!

     

    To add onto this: specifying different VSF domain IDs will prevent members from joining a different stack if the VSF links from one stack are inadvertently connected to a member of another stack.

    Thank you for your replay.

    Does it mean that two VSF stacks, that are physically non-connected, can have the same domain ID?

    If you have two VSF Fabrics totally (logically and physically) separated each other...yes, the same VSF Domain Id can be used on both VSF Fabrics...this approach is possible because you're accepting (and granting) the assumption that those two VSF Fabrics will never connect each other and so they will never interfere each other...IF this essential assumption is (or will became) invalid then do yourself a favor and simply use two different VSF Domain Ids (1 and 2 or 10 and 20...), it's simple...they are just numbers.

    I have a very similar question so didn't want to create a new thread, i've been trying to find the answer from here:

     

    https://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-a00050273en_us-4.pdf

     

     

    My question on VSF domain id's is this, is there a number limitation?

     

    ie: can the domain be ANY number? Or is is limited to a number between say 1 and 1024 ?

     

    Tia!

    Hi @tbb, the VSF virtual chassis domain ID value can be any integer in the range from 1 to 4294967296 (that's from Aruba 3810 / 5400R Management and Configuration guide for ArubaOS-Switch 16.08 available here: http://h22208.www2.hpe.com/eginfolib/Aruba/16.08/5200-5491/index.html#v36580555.html).
