Additonal Requirement for Usage Monitoring

To support Usage monitoring you will need an additonal network interface card installed on the host to capture traffic from an external hardware switch and pass to the monitoring interface on a v35.

vmxnet3 interfaces are capable of speeds up to 10 Gbps, but our virtual machines are not. Monitoring is supported up to 1 Gbps.
