Hello
The VSF Configuration Guide has the following statement on page 10.
https://www.arubanetworks.com/techdocs/AOS-CX/10.10/PDF/vsf.pdf"In a standard deployment, uplinks should be from primary and secondary"It is good to keep in mind that only the designated primary and secondary can be VSF conductors. If both of them fail at the same time, the remaining member switches will reboot, wait for conductor and keep their network ports down. They will not elect new conductor among them and operate as stack.
Also if there is a stack split and primary and secondary are in one fragment, while in the other fragment there are only member switches, the fragment with the member switches will reboot and wait for a conductor with disabled ports. Again no new conductor will be elected among them.
If you think that the uplink bandwidth of the conductor and secondary is not sufficient or if you want to avoid east west traffic within the stack (first send from member to conductor and then from conductor to 5400R) you can add uplinks from every member as well. But the main uplinks (with redundancy, for example LAG) should be from conductor and secondary because this will ensure that the stack remains operational in case of a failure.

Hi,
I am creating a 6 member AOS-CX VSF stack with 6300's in a ring topology. The devices connected to the 6300 stack will be end user workstations and AP's. The 6300 stack will be configured to have a master and standby nodes with the remaining 4 nodes being members. The 6300 stack will have uplinks to my 5406R 2 member VSF stack (AOS).
Question
What is the best practice in cabling physical uplinks from the 6300 VSF stack to the 5406 VSF stack? Do I just need uplinks from the master/secondary nodes or all nodes? I have the capacity for as many 10GB SFP+ as necessary.
Thanks
