Why each option
In the `show control connections` output, the 'connect' state signifies that the control plane connection between the vEdge router and the vSmart controller is fully established and operational.
If the control connection were down, the state would typically be 'down' or 'disconnect'.
While 'up' is technically correct, 'connected' more precisely describes the specific keyword shown in the output, implying full establishment.
A connection attempt in progress would typically be indicated by states like 'connecting' or 'init', not 'connect'.
The 'connect' state confirms that the DTLS/TLS tunnel is successfully built and maintained, indicating the vEdge router is actively participating in the SD-WAN control plane and exchanging OMP routes with the vSmart controller.
