You can use ERSPAN to mirror traffic from one or more source ports on a virtual switch, physical switch, or router and send the traffic to a destination IP host running NNM. The following ERSPAN virtual environments are supported for NNM:

  • VMware ERSPAN (Transparent Ethernet Bridging)
  • Cisco ERSPAN (ERSPAN Type II)

Tip: Refer to the Configuring Virtual Switches for Use with NNM document for details on configuring your virtual environment.

High Performance Mode

To run NNM in High Performance mode, you must enable HugePages support. HugePages is a performance feature of the Linux kernel and is necessary for the large memory pool allocation used for packet buffers. If your Linux kernel does not have HugePages configured, NNM automatically configures HugePages per the appropriate settings. Otherwise, if your Linux kernel has defined HugePages, refer to the Configuring HugePages instructions.

The following virtual environments are supported for running NNM in High Performance mode:

  • VMware ESXi/ESX 5.5
  • VMXNET3 network adapter
  • VMware ESXi/ESX 6.0.0
