For an overlay logical switch, check that the netcpa on the host is connected to the central control plane.

Prerequisites

Find the controller that the logical switch is on. See Check the CCP for the Logical Switch.

Procedure

  1. SSH to the controller that the logical switch is on.
  2. Run the following command and verify that the controller shows the hypervisors that are connected to this VNI.
    get logical-switch 5000 transport-node-table
  3. On the hypervisors, run the command /bin/nsxcli to start NSX CLI.
  4. Run the following command to get the CCP sessions.
    host1> get ccp-session
    Session Index State Controller
    Config  0     UP    10.33.74.163
    L2      5000  UP    10.33.74.163

    You should see a Config session on one of the CCP nodes in the CCP cluster. For every overlay logical switch, you should see an L2 session to one of the CCP nodes in the CCP cluster. For VLAN logical switches, there are no CCP connections.
