 MCLAG server connections are used to connect servers to the pair of switches using multiple ports (Dual-homing).
+Switches should be configured as an MCLAG pair which requires them to be in a single redundancy group of type `mclag`
+and Connection with type `mclag-domain` between them. MCLAG switches should also have the same `spec.ASN` and
+`spec.VTEPIP`.
