trafficPolicyVersionMarker

For your first request to ListTrafficPolicyVersions, don't include the TrafficPolicyVersionMarker parameter.

If you have more traffic policy versions than the value of MaxItems, ListTrafficPolicyVersions returns only the first group of MaxItems versions. To get more traffic policy versions, submit another ListTrafficPolicyVersions request. For the value of TrafficPolicyVersionMarker, specify the value of TrafficPolicyVersionMarker in the previous response.
