  • 1.  6300 3-Switch Stacking

    Posted Jan 04, 2024 05:52 PM

    Hey folks, I have an issue with some stacking for a group of 6300 switches. I am not able to get my third switch to add to the VSF. I have the VSF configured, and the first two switches are working like they should be, but I have not been able to get my third to join the VSF. I am trying to get them as a ring for the VSF. My research has pointed me to the place below. I do have another multiple 6300 switch stack, but the ports are a little different than what is here, and we are not having any issues. 

    Forming a four-member ring setup using auto-stacking command (arubanetworks.com)

    This is what I get after running 'show vsf'

    This is how my ports are configured.

    Now when it comes to the actual physical cables I am using 50G SFP56 DAC Cables. They are plugged in as follows:

    1/1/50 -> 2/1/49

    2/1/50 -> 3/1/49

    3/1/50 -> 1/1/49

    Is my cabling off or is my config off or is there something that I have missed?

    I like this conversation thread because I feel like the instructions for stacking have changed since we first started using Aruba CX switches.  Your DAC cables are correct. What is your OS version? We are on 10.10.1060. Once we have member 1 on this firmware downloaded via ZTP, we just power each additional member one at a time top to bottom and they add automatically. Since you have already attempted this on member 3 and it failed, you will likely need to run a "erase all zeroize" on member 3 if you haven't already. If after zeroize it still hasn't successfully added to the stack on its own, use the following commands:

    changeme(config)# vsf member 1

    changeme(vsf-member-1)# link 1 1/1/49

    changeme(vsf-member-1)# link 2 1/1/50

    changeme(vsf-member-1)# exit

    changeme(config)# vsf renumber-to 3

    This will save the VSF configuration and reboot the switch.

    Do you want to continue (y/n)? y

    I am running version 10.10.1100.

    Thank you for the help. I got it to work by just zeroing out the third switch. I do not remember putting a config on that switch but when I zeroed it out the device automatically joined the stack.

    The one question I have is are you running those commands on the third switch or are you running them on the first switch. What is confusing to me is when you do 'vsf member 1' I am thinking your are accessing the Master in the stack.

    Yes, it is kind of confusing, but it is correct because the device hasn't been renumbered yet, so it is technically member 1 until it is renumbered.

    It makes sense though if you think about it from the factory default. Your turning on the vsf protocol by doing the 'default' of vsf member 1 then telling the device your not the number 1 your whatever number.
