The communication between the nodes occurs through SSL encrypted channels; without this, our spine and leaf nodes will not be able to register with the controller(s), so once we have checked that our cables are connected and we can see everything on layer 2, we should check whether we are communicating in the right manner with the nodes.
We can check that the nodes have a valid SSL certificate.
- Navigate to
Fabric|Inventory|Fabric Membership. - Check that the nodes all have an SSL certificate.
We can also check that the communication is working using the following command on the APIC:
netstat -ant | grep :12Check that the output lists the connections as ESTABLISHED:
apic1# netstat -ant | grep :12 tcp 0 0 10.0.0.1:12151 0.0.0.0:* LISTEN <truncated> tcp 0 0 10.0.0.1:12567 10.0.248.29:49187 ESTABLISHED tcp 0 0 10.0.0.1:12343 10.0...
