Hi @Robo123 

With the 9600X-SUP-2 you have to use a software from 17.8.x and newer:

https://software.cisco.com/download/home/286328203/type/282046477/release/Cupertino-17.9.3

I would use the 17.9.x Train at the moment.

You cant use a 17.6.x on the C9600X-SUP-2

https://www.cisco.com/c/en/us/support/docs/switches/catalyst-9300-series-switches/214814-recommended-releases-for-catalyst-9200-9.html

Note:  # For C9400X Series (C9400X-SUP-2, C9400X-SUP-2XL), C9500X Series (C9500X-28C8D) and C9600X Series (C9600X-SUP-2), the recommendation is Cisco IOS-XE 17.9.1 or later versions.

You just have to check the documentation on the cisco support, normaly you find all the informations there.

High Availability Configuration Guide

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9600/software/release/17-7/configuration_guide/ha/b_177_ha_9600_cg/configuring_cisco_stackwise_virtual.html#topic_pvq_lyn_lkb

Restrictions for Cisco StackWise Virtual 17.7.x

• This feature is not supported on the Cisco Catalyst 9600 Series Supervisor 2 Module.

17.9.X:

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9600/software/release/17-9/configuration_guide/ha/b_179_ha_9600_cg/configuring_cisco_stackwise_virtual.html#topic_pvq_lyn_lkb

17.10.X:

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9600/software/release/17-10/configuration_guide/ha/b_1710_ha_9600_cg/configuring_cisco_stackwise_virtual.html#restrictions_for_cisco_stackwise_virtual_9600

Cisco IOS XE Dublin 17.10.1

Cisco StackWise Virtual

Support for this feature was introduced on the Cisco Catalyst 9600 Series Supervisor 2 Module (C9600X-SUP-2).

17.11.X:

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9600/software/release/17-11/configuration_guide/ha/b_1711_ha_9600_cg/configuring_cisco_stackwise_virtual.html#restrictions_for_cisco_stackwise_virtual_9600

So starting with 17.10.x SVL is for the C9600X-SUP-2 supported. But see in the documentation that there are some hints:

Note: This does not apply to the Cisco Catalyst 9600 Series Supervisor 2 Module (C9600X-SUP-2).

Is the supervisor come with that Version ?

If that is the latest - some of the IOS you can not download  i guess here ?
