I am planning to upgrade my Nexus 7009 and when I did the "show impact", it asked me to run "show lacp issu-impact" which gave me a few ports that are not "ISSU ready". I researched and found that even though they don't have "lacp fast rate" enabled, their LACP neighbor does.

I am wondering what impact this would cause if I go ahead with the upgrade? I am guessing that this port will drop out of the VPC/port-channel that would cause a few packet losses, but should resume quickly over the other links in the port-channel? The port-channels are either dual-connected to two separate Nexus chassis, or to two FEX each single-homed to each Nexus chassis.
Hello,I understand that Contracts in ACI that are enfored by the leafs are stateless ACL. When is an ACI Contract stateful?- as far as I know when using AVS/AVE?- what about when using Kubernetes/Openstack integration with ovs?
