Prepare G-vTAP Agent to Monitor Traffic

A G-vTAP Agent is an agent that is deployed in the VMs. This agent mirrors the selected traffic from the VMs (virtual machines), encapsulates it using GRE or VXLAN tunneling, and forwards it to the GigaVUE® V Series node.

Note:  The G-vTAP agent installation is applicable only when the G-vTAP is your traffic acquisition method.

A G-vTAP Agent consists of a source interface and a destination interface. The network packets collected from the source interface are sent to the destination interface. From the destination interface, the packets traverse through the L2GRE or VXLAN tunnel interface to the GigaVUE V Series node.

A source interface can be configured with one vNIC. While configuring a source interface, you can specify the direction of the traffic to be monitored in the VM. The direction of the traffic can be egress or ingress or both.

Note:  AnyCloud deployment supports monitoring for only one vNIC per guest VM, although it is still possible to have a dedicated tunnel vNIC on a guest VM in addition to monitored vNIC.
