In this example Request ID “1-2212"
1 = is the Internal ID number used by TPAM to identify the Primary and Replica. Normally this will be 1 for the Primary appliance and 2 for the Replica, but this will change if multiple enrollments are performed or if there are multiple replicas for example. The 1 indicates the request was generated on the Primary appliance. If it was 2-2212, the request would have been generated on the replica.
2122 = This is a unique number starting at 1 and increasing for every request.
