CSCvo19594 - Nexus 9000-FX QinQ VxLAN BGP EVPN. Multitag not functional after device is reloaded

[JonasP]

Hi,
We use the option "switchport trunk allow-multi-tag" and are facing CSCvo19594.
In bug CSCvo19594, it indicates that NX-OS 9.2(3) and 7.0(3)I7(6) is known as "fixed released". We have tested in this 2 versions and they are still affected by this bug. We have tested in 9.3 and the result is the same.
So I have 2 questions :
- when this bug will be definitly fixed ?
- do you found a way to identify if a switch is affected or not by this bug ? We are running more than 30 Nexus9300 and we can't reload them with the command "reload ascii" just because we assume the switch is affected by the bug.
Thanks.

Hi Jonas,

Did you ever find a solution for that problem? I guess we're hitting either the same or a very similar Bug. Configuration works as intended, but after shut/no shut of the Port the switchport trunk allow-multi-tag stops working and traffic with multiple tags is not forwarded by those ports anymore. Even more - removing this command from the interface makes it working again!!! Re-adding after removing that command from the interface does not change the forwarding behavior anymore.

I already opened a TAC-Case but didn't receive any valuable feedback by now...

Regars,

Michael
