VMware vCenter network settings | Trend Micro Service Central

Views:

After successfully deploying your Virtual Network Sensor, decide which network configurations to use based on your requirements.

If your throughput is less than 2 Gbps, your ERSPAN data port configuration can use a vSphere Distributed Switch, a vSphere Standard Switch, or a PCI passthrough.
If your throughput is equal to or greater than 2 Gbps, using a PCI passthrough is recommended. Your data port must be able to connect to the internet.

To determine which deployment scenario is best for your network security needs, see Mapping your deployment with VMware vCenter.

Throughput	Recommended Network Settings
Throughput of monitored traffic is less than 2 Gbps	For information about monitoring internal network traffic, see: Configuring internal network traffic with the VMware vSphere Distributed Switch (promiscuous mode) Configuring internal network traffic with the VMware vSphere Standard Switch (promiscuous mode) Configuring internal network traffic with the VMware vSphere Distributed Switch (SPAN)
Throughput of monitored traffic is less than 2 Gbps	For information about monitoring external inter-VM traffic, see: Configuring external inter-VM traffic with the VMware vSphere Distributed Switch (RSPAN) Configuring external inter-VM traffic with ERSPAN For information about monitoring external network traffic from other external sources, see: Configuring external network traffic with the VMware vSphere Distributed Switch (RSPAN) Configuring external network traffic with the VMware vSphere Distributed Switch (SPAN) Configuring external network traffic with the VMware vSphere Standard Switch (promiscuous mode/RSPAN)
