We are currently evaluating the features of the VNA gateway for Cisco Viptela in CAPC, but we have some problems. The connection between the gateway and the vmanage is successful, we get the devices with the right interface ip's, but we don’t get any SLA path information.
The following was seen in the gateway log after enabling OC_AQUISITION debug.
