Turned on Mac Learning - linux systems broke

Hey Guys and Gals,

We are upgrading to NSX T from V and we created some bridges and turned on MAC Learning.  It appears Linux systems were impacted.  They had higher vCPU activity and had issues running their applications.  Reboot didn't work, vMotion brought the problem to other hosts.

 

Ultimately a reboot of the host worked.  and then moving the VM to that host.  Why?  Did anyone else run into an issue like this?

 

Teamwork

Kaizen!

Yes!  We had the exact same problem.  Were you able to maintain stable bridges after rebooting the hosts?  Did you complete the migration to NSX-T?  We were considering doing Promiscuous mode instead.  Our customer is reluctantly considering a full shutdown of critical applications, which we would all prefer to avoid.  What did you end up doing?
