    Hi everybody,

     

    I hope you are doing fine, have a few questions:

     

    1) Let say we have Virtual chasis with Sw1,SW2,SW3 with following roles:

    SW1 is master

    SW2 is back up RE

    Sw3 is line card

     

    Can Sw1 and SW2  forward tproduction traffic though they have assumed Master and back up RE role?  Most likely they can as it is very similar to VDX fabric technology in Brocade, just want to be sure as I have never configured EX switch in Virtual chasis .

     

    Thanks and have a nice day!!

    Absolutely yes.  I would recommend using a pre-provisioned VC configuration, I think easy to troubleshoot any VC issues.

    Thanks for the reply.

    Just thought of another question if you could answer that will be great.

     

    Master and back up election in Virtual chasis:

    If two switches have the same priority, what is next criteria is used to declare one switch as a master?

    Is premption enabled by default?

     

    Appreciated!!
