    Description

      Steps to reproduce

      1. Configure two one node cluster
      2. Enable uni-direction XDCR from cluster one to cluster two using TLS
      3. run a tcpdump on cluster 2 capturing all the traffic from cluster one

        sudo tcpdump -lvni [INTERFACE] -w /vagrant/xdcr.pcap  host [CLUSTER ONE IP ADDRESS]
        

      Problem

      When reviewing the tcpdump, there is traffic over port 8091:

      While this is a small amount of traffic I would expected there to be none.

      Expectation
      All communication to be over encrypted ports

      Logs

      Tcpdump:
      [^xdcr2.pcap]
