Hi everyone,
I'm setting up a corporate LAN with two Cisco Catalyst 9300X-24UX-E switches in the core. I've already cabled the network with fiber optic backbones connecting each floor of the building to the core using the SFP+ ports.
My goal is to create a redundant core, but I've discovered that I don't have the StackWise+ cables needed to enable stacking on the 9300X switches.
Is it possible to create a virtual stack between the two switches without using StackWise+ cables? If not, what alternatives would you recommend to ensure redundancy and high availability in the core?

NO not possible Flex stack on these models.
2 Option,
1 order stack cables.
2. Create Layer 2 Link Bundle between these 2 Cat 9300 and connect access switch,(one of the Link will be spanning blocking you can use priority which link you like to active.
Other way you can do Layer 3 between access switches to Cat 9300 using any IGP to load share,

Get StackWise cables.
There is really no excuse to skimp on buying StackWise cables. They are even cheaper in the gray or used market.

Fabiano,
Unfortunately, you cannot create a StackWise Virtual with the 9300 series. However, you can do this with a 9400, 9500, or 9600 series switch. Having a conversation with your SE is a good idea. At Cisco Live this year, we announced a new feature called mLAG that will be available later this year. If you are familiar with Nexus, it is similar to the VPC feature. You will have independent data and management planes, but you can build an EtherChannel from both switches to an access switch.
I hope this helps.

switch stack-speed high
Enter this command into all the 9300X switches or else it will not join the stack.
