A question that comes up frequently when setting up the collector portion of EUEM is if it can handle traffic feeds larger than 1Gbyte.  The virtual and hardware option both have this capability.


Virtual Collector:

When deployed, the default nic driver is set to E1000.  Before powering the collector on for the first time, you have the ability to the virtual nics attached to the vm and install new virtual nics using the VMXNET3 driver.  This driver uses less resources on the ESXi host and supports 10 Gbyte traffic  This driver can also be changed at anytime during the use of the collector but to remove/install new nics, the vm will need to be powered off.

***Note:  if you choose to change the management nic driver, the collector will need to be re-licensed.


From VMWare:

  • VMXNET 3: The VMXNET 3 adapter is the next generation of a paravirtualizedNIC designed for performance, and is not related to VMXNET or VMXNET 2. It offers all the features available in VMXNET 2, and adds several new features like multiqueue support (also known as Receive Side Scaling in Windows), IPv6 offloads, and MSI/MSI-X interrupt delivery. For information about the performance of VMXNET 3, see Performance Evaluation of VMXNET3 Virtual Network Device. Because operating system vendors do not provide built-in drivers for this card, you must install VMware Tools to have a driver for the VMXNET 3 network adapter available.


***Note: VMWare tools are already embedded in the BMC EUEM Collector OS


Hardware device TS-4200


The TS-4200 series has the following network ports on the front of the device:

  • Four capture ports dedicated to traffic capture.
    For 10 Gb traffic feeds, you must use a port that supports 10 Gb traffic.
  • One management port for managing the device; for example, to perform initial configuration tasks via the CLI. You must also use this port to feed external devices which rely on system data.
  • One spare port that can be configured as either a traffic capture port or a management port using the spareniccommand in the system CLI.
