Deploying Virtual Stackwise Catalyst 9400

Question

I am looking into deploying Virtual Stackwise on the Catalyst 9400 series switches. I wanted to know based on best practices where should the VSL links be deployed on the Sups or the modules? Is there a Cisco document which documents this?

Thank you

Answer 1

According to the documentation for Configuring Cisco StackWise Virtual The SVL link needs to be connected to the sup-module.

StackWise Virtual Link (SVL) connections are established only through 10G or 40G uplink ports on the
supervisor module. You cannot establish an SVL using a 10G port on one switch and a 40G port on the
other switch.

Please refer to the following Cisco guide for details.
Although this is not a best practice, however, the following link contains the requirements.

Configuration guide for Cat 9400 and StackWise Virtual Link "configuring_cisco_stackwise_virtual.pdf".

And this is the design guide(CVD)

The following link is CVD "CVD-Campus-LAN-WLAN-Design-Guide-2018JAN.pdf".

CVD is a document that describes a verified configuration. It will be possible to find Best Practice. For deploying devices to the network

This also contains information Cat9x and StackWise Virtual Link.

As I note in the comments, I do not know if the answer to stack overflow is only to allow link paste.
However, I know that finding valid information on the official Cisco site is difficult.
