Cisco ACI - Troubleshooting common EPG faults - Encap already used in Another EPG

Here is another short flowchart to help you troubleshoot common issues seen after an ACI migration. For those who are performing large enterprise migrations consisting of 500+ servers, it is possible that a physical leaf port has a static binding to two different EPG's. When this occurs, you will see a fault in ACI with a reference message of "Encap Already Used in Another EPG". In my experience, the fault will mention the port that raised the alarm. At the end of the day, you need to remove that port from the last EPG it was added to. Sometimes, there are instances where a trunk port was incorrectly added to an EPG as an access port which the flowchart will also help you determine.
