Stackwise virtual not working either

So after trying to use vrrp/vrrs (and getting no where as it seems nobody has ever tried this on a 9500 based on responses to a previous email) I thought I would try stackwise virtual which to be fair I have had more success with but cannot get dual action detection to work.

I have the following config.

 

stackwise-virtual
domain 1
dual-active detection pagp trust channel-group 1

 

 interface HundredGigE1/0/25

No idea why the port channel wont come up as I have followed this https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9500/software/release/16-12/configuration_guide/ha/b_1612_ha_9500_cg/configuring_cisco_stackwise_virtual.html#concept_ad5_4wx_31b

I assume you have reloaded both switches after configuring SVL and DAD ?

Unfortunately seems to go from bad to worse !.

 - from show log

%ETC-5-L3DONTBNDL1: Hu2/0/27 suspended: PAgP not enabled on the remote port.

 

I have tried reloading the entire stack - still the same. 

I am starting to think that there is either a license problem or a bug that doesnt allow for pagp port channels.

Details of license and version (just in case)

Hello,

 

I checked for bugs, none found. It does definitely sound like one. Weird that it doesn't work with PAgP, which is Cisco-proprietary, but is does with the open standard LACP.

 

If you have a support contract, you could raise a TAC case to report this is a bug.
