Issue

  • When running network ping without specifying a source LIF, the ping fails when using a specific source node
network ping -node node1 -destination 8.8.8.8
no answer from 8.8.8.8
  • Packet trace shows that
    • the ping's source MAC address is on the specified node, and the source IP is the cluster_mgmt LIF
    • the ping reply's destination MAC is on a different node, and the destination IP is the cluster_mgmt LIF
  • EMS contains netinet.ethr.duplct.ipAdrr events for the IP of the cluster_mgmt LIF
  • In the output of  node run -node * ifconfig the IP of the cluster_mgmt IP appears multiple times
