Cisco Catalyst c9500 virtual stacking - simple configuration

**make sure the software version is the same
**make sure the same license type
**make sure you use the same stackwise virtual domain

**do this on each 9500

**configuring the stackwise virtual domain
conf t
stackwise-virtual
domain 1

**configuring the virtual link
conf t
interface range hun1/0/49 - 50
stackwise-virtual link 1

***update: if you get an error when adding the second interface: "The speed of the interface does not match the speed of the interfaces on SVL link 1"...This is a BUG. Error does go away when you upgrade to 16.12.4.***

**configuring dual active detection (DAD)
interface twe1/0/48
stackwise-virtual dual-active-detection

**reload

**verification commands
show switch
show stackwise-virtual dual-active-detection
show stackwise-virtual link

Hello! Thanks for the video. One question: Why did interfaces HunderGigEth1/0/50 failed to be a member of the stackwise virtual link? I noticed that the speed of the interface did not match the speed of the interface on SVL 1. What went wrong with that? Thank you in advance!

Hello! Got a question to ask. We also have two 9500 and plan to deploy in a StackWise virtual. My questions to you, how many physical cables are needed to connect? I plan to use the last two 100G interfaces. But I also noticed that you configured DAD interfaces, does that mean I need to connect another cable on another interfaces? Hope that makes sense. Just trying to visualize it, the physical layer. Thanks

Hi, Will DAC/AOC cables both work for SVL/DAD links, or only SFP transceiver

Thanks of your video, my question is can a 1G SFP module on the C9500-48Y4C switch to the C2960-X access switches? answer me

Before configuring stackwise virtual in Cisco 9500 switch, I have connected cables in both switches but port not coming up, executed no shutdown also could you please help on this

Hello, how to set up the priority of switch? "switch 1 priority 15" seems not work
