Hi,
Vstack is used for smart install or no-touch upgrade. If you are not doing that, you don't need the feature. See the link for more info.
To determine whether a Cisco IOS or IOS XE device is configured with the Smart Install client feature enabled, use the show vstack config privileged EXEC command on the Smart Install client. The following is the output of the show vstack config command in a Cisco Catalyst Switch configured as a Smart Install client. The output for Role: Client from the show vstack config command confirms that the feature is enabled on the device.
switch#show vstack config Role: Client Vstack Director IP address: 10.1.1.100
Note: Smart Install client functionality is enabled by default on Cisco IOS switches.
