Linux Agent Installation

Refer to the following sections for the Linux agent installation:

Single vNIC Configuration

A single vNIC acts both as the source and the destination interface. A G-vTAP Agent with a single vNIC configuration lets you monitor the ingress or egress traffic from the vNIC. The monitored traffic is sent out using the same vNIC.

For example, assume that there is only one interface eth0 in the monitoring VM. In the G-vTAP configuration, you can configure eth0 as the source and the destination interface, and specify both egress and ingress traffic to be selected for monitoring purpose. The egress and ingress traffic from eth0 is mirrored and sent out using the same interface.

Using a single vNIC as the source and the destination interface can sometimes cause increased latency in sending the traffic out from the VM.

Example of the G-vTAP config file for a single vNIC configuration:

Note:  The GigaVUE Cloud Suite for AnyCloud supports only single NIC G-vTAP Agent configuration.
