Odd one here - traffic works for SOME of the source NAT IPs, but not others.If we stop traffic to from one source NAT IP for period of time (few hours) it never works again.Source is uEPG in VRF1.Destination is a handful of customer owned devices tha...

I have numerous uSEG EPGs in the Fabric, all from various App Profiles tied to our VMM Domain set with micro-segmentation. This uEPG deployment is pretty straight forward and working great. Have a number of other App EPGs defined from connections to...

Thank you @Robert Burns !! Might ping you if any specific questions but the above makes perfect sense, I've just not deployed EPGs in this exact manner before.

Where is the Micro-segmentation allowed for this? I know with our VCenter connection its defined on the VM Domain. I see there is option under "static ports" section of the App EPG that looks like I can define the VPC in use and do Micro-Segmentatio...
